Résumé :
Roughly 50,000 people are injured in bicycle collisions with motor vehicles each year. The Hank Bicycle Simulator provides a virtual environment to study and reduce this risk by safely investigating the interaction of bicycle riders and traffic, particularly for bicyclists crossing streets. The bicycle simulator design focuses on the bicycle and rider inertia, the predominant dynamic element for riders moving from a stopped position. The Hank Bicycle Simulator's flywheel provides instantaneous inertial response while a servomotor provides simulated wind resistance to pedaling. This work describes the simulator design and a validation experiment that compares the simulator performance to theoretical predictions. The Hank Bicycle Simulator achieved initial acceleration with less than 0.20% error at realistic rider weights. The observed terminal velocity achieved less than 3.75%, with smaller errors for heavier riders. This allowed the rider to cross a street with about a 60 ms time difference between the simulator and a real-life rider. The Hank Bicycle Simulator was also validated through various physical experiments measuring the system inertia, the time delay of the electrical components, and overall system performance. Such careful system validation for a mechanical feedback system is relatively rare in simulation research and is unique among previous reports of bicycle simulators.

Résumé :
Purpose Whilst motorcycling is an activity of pleasure in most parts of the world, in India, it is a regular mode of commuting. The number of registered motorized two wheelers increased at the rate of 14.7 percent during the year 2016-2017 to reach the figure of 20.19m in 2018. But, with this increase, the number of motorcycle road accidents is also increasing. Uncomfortable riding clothing is one of the major factors for motorcycle rider’s muscular fatigue, which might at times lead to serious accidents. No kinematic human models have been, so far, used for the design of protective, functional and aesthetic looking products, and the result is, hence, a compromised fit that is not protective or comfortable. The purpose of this paper is to develop virtual 3D human body models for specific postures of a motorcycle rider. Design/methodology/approach Kinematic analysis of a motorcycle rider was conducted to identify typical body postures obtained by the motorcycle rider while mounting and riding a motorcycle. The identified body postures were mapped on a virtual parametric human model to obtain digital model of a motorcycle rider. 3D garment patterns for jacket and trouser were developed on all the four body postures. 3D patterns were flattened out to get 2D flat patterns that were compared and analyzed, and appropriate pattern shapes from each of the four postures were selected. Virtual fit analysis was conducted for the finally garment. Findings It is well established that a static 2D anthropometry fails to accurately capture the dimensions of complex 3D human form, yielding poor garment fit. Therefore, in this study, virtual, 3D human body models were developed in selected dynamic poses. Garment patterns developed in 3D have the typical movement inbuilt in them; hence, they offer more comfort and ease of motion to the wearer. Originality/value The identification of typical body postures of motorcycle rider has not been done before. The CAD models developed in the study can be used for the generation of ergonomic garment patterns for the motorcycle riders.

Résumé :
In this research we present the modules of virtual reality augmented cycling (VRAC) system for people post stroke including mechatronic rehabilitation system and virtual environment. VRAC modules are designed as modular system to suit most stationary bicycles in virtual reality (VR) cycles without changing its parts. VRAC consists of novel hardware components embedded with sensors that are use to gain of a stationary exercise bicycle. VRAC modules include balancing pedals module, rpm (rotation per minute) counter module, safety driving module , handlebar module and acquisition data module. The handle system is a novel type of hand dynamometer, which measures applied physical force to control dynamic motion of the rider in the virtual environment. The data from sensing systems are measured by Arduino microcontroller as a acquisition data module and sent its results to virtual environment processed by computer. The prototype of the system was successful in demonstrating that a modular mechatronic kit can monitor and record kinetic, kinematic and physiologic parameters of riders.

Résumé :
Grounded in social facilitation theory, this study compared the impact on exercise intensity of a virtual versus a live competitor, when riding a virtual reality-enhanced stationary bike (“cybercycle”). It was hypothesized that competitiveness would moderate effects. Twenty-three female college students were exposed to three conditions on a cybercycle: solo training, virtual competitor, and live competitor. After training without a competitor (solo condition for familiarization with equipment), participants competed against a virtual avatar or live rider (random order of presentation). A repeated-measures analysis revealed a significant condition (virtual/live) by competitiveness (high/low) interaction for exercise intensity (watts). More competitive participants exhibited significantly greater exercise intensity when competing against a live versus virtual competitor. The implication is that live competitors can have an added social facilitation effect and influence exercise intensity, although competitiveness moderates this effect.

Résumé :
The demands of high-quality dynamic performance and short development time for vehicle production can only be fulfilled by the application of advanced design, simulation and optimization technologies. Virtual prototyping (VP), the analysis and simulation technology based on a fully developed computer model, represents a future way for cost and time efficient design of vehicles and can perform the same as those on the physical prototyping. This paper describes an integrated modeling method, based on the topological structure of a heavy vehicle and oriented to ride dynamics, of a human-vehicle-road system. A multi-body simulation model was chosen as the integration platform for the virtual prototyping since it provided the flexibility to integrate all relevant aspects such as rigid body movement, road-induced vibration and the driver’s responses to the vibration. The time domain model of the stochastic excitation from the road irregularities was numerically reconstructed as input data to VP and the feeling evaluation model in time domain, equivalent to conditional frequency evaluation, was used to the vehicle’s riding comfort simulation. Through integrating the sub-models in VP and combining the data of the sub-models it became possible to predict dynamic performance of vehicles by virtual prototyping technology.

Résumé :
Rider visibility has been considered an important issue in car-motorcycle accidents due to the frequency of unperceptive and negligent driving behavior. Mostly car drivers stated that they didn’t see the rider before the collision. This study aims to investigate the contributing factors that reduce rider visibility in point of view of car drivers for car-motorcycle accidents. The study considered the car-motorcycle accidents which occur in the built-up area. Statistical data analysis categorized the accidents into six dominant accident types. Twenty-five accidents were selected by accident types for simulation analysis. The selected accidents were simulated in Virtual Crash software during 5 seconds before the collision. The simulation analysis evaluated that the view obstructions, blind spots and high speed were the contributing factors that reduce rider visibility in car-motorcycle accidents. The simulation plots identified the involvement of contributory factors and variation within the time interval. The comprehensive in-depth analysis also evaluated that no collision avoidance maneuvers were performed by most of the car drivers due to visibility issues before the collision. Safety systems were proposed based on observed factors according to car and motorcycle perspectives for collision avoidance.

Résumé :
This work presents SimBike, a virtual bicycle simulator that uses non-conventional motor, sensory and sensorimotor devices to provide greater user involvement and comfort. SimBike aims to recreate the activity of riding a bicycle by exploring possibilities of electronic devices, such as making curves with the handlebar or body-weight, pedaling, braking, among others. It also offers feedback commonly expected by the rider, such as wind sensation varying according to speed and the sensation of trepidation on uneven terrain. The simulator was evaluated with 16 users, obtaining positive results regarding user experience, comfort, and immersion. As future work, we propose to improve some features to adapt the simulator for all users, regardless of their weight and height.

Résumé :
A number of diseases can be prevented through active lifestyles. Yet, despite technological and non-technological interventions, many people do not engage in exercise. Immersive virtual reality (iVR) offer the opportunity for highly engaging and entertaining experiences. Their designs affects how people are motivated (or not) to engage and exercise. To maximise the benefits of these technologies a model of motivation that can help designers is needed. There is need to investigate psychological constructs of wellbeing: how do users engage with wellbeing technology’s designs? What motivates or demotivates them? And how can constructs borrowed from psychology aid better technological designs? This thesis introduces a framework for comparing designs in VR exergames and use technologies as instruments to study motivation. An iVR exergaming platform – VR-Rides – was developed to explore designs for wellbeing over an iterative design, development and evaluation process. The thesis addresses challenges by understanding users’ perceptions, evaluating iVR designs based on psychological constructs and informing future designs based on findings to promote wellbeing goals. Furthermore, various designs, game narratives and mechanics were developed to engage players in activities that purportedly lead to wellbeing. The research applied a quantitative research methodology, facilitated across five studies conducted in diverse social settings. Four studies particularly explored VR-Rides’ designs for participants’ engagement and motivation in an exergaming setup. In the fifth study we tested the feasibility of the VR-Rides platform to assess memory for age-related cognitive decline. The findings show psychological constructs have a central role in understanding users’ enjoyment and motivation with wellbeing platform, highlight motivating factors, and bridge the gap between technology designs and wellbeing constructs.

Résumé :
Pre-Trip Inspection of the truck and trailer is one of the components of the current Commercial Driver's License (CDL) test. This part of the CDL test checks the ability of the student to identify the important parts of the commercial vehicle and their potential defects. The Virtual Check Ride System (VCRS), a computer-based application, is an assessment and feedback tool that mirrors the inspection component of the actual CDL. The VCRS has provided an after action review (AAR) via a feedback session that helps in identifying and correcting drivers' skill in inspecting parts and for overall safety. The purpose of this research is to determine the effectiveness of the VCRS in truck driving training programs. An experimental study was conducted with truck driving students at Mid Florida Tech, located in Orlando, Florida. The students were divided into control and experimental groups. Students in the both groups received regular training provided by Mid Florida Tech. The experimental group received additional training by making use of the VCRS. A total of three paper-based tests were given to all subjects during first three weeks; one test at the end of a week. Both groups were given the same paper-based tests. A two-way analysis of variance was conducted to evaluate the effect of the VCRS in the experimental group. This analysis found a significant difference between control and experimental groups. This effect showed that the students in the experimental group increased their performance by using VCRS. Moreover, there was a main effect in the scores of each week. However, there was not an interaction between the two factors. Follow up Post Hoc tests were conducted to evaluate the pair-wise differences among the means of the test week factors using a Tukey HSD test. These Post Hoc comparisons indicated that the mean score for the third week's test scores were significantly better than the first week's test score in the experimental group. It was concluded that the VCRS facilitated learning for the experimental group and that learning also occurred for both groups as a result of repeated testing.

Résumé :
Water is the source of life. Leonardo da Vinci, constructor of the drainage system of a swamp area north of Rome, said that “water is the blood of the soil”. Without water there is not fertile soil and without any of them there is no harvest. Sustainable Agriculture Management is all about how to develop and improve the use of different resources to make agriculture more sustainable. This study is about how to apply this concept into the study area. The Balkhash Lake is among the biggest lakes on earth, but due to unreasonable water utilization, the lake is facing the same fate as the Aral Sea. The lake belongs to the Ili Balkhash Basin IBB that is shared by two countries; Kazakhstan and China. Most of the water (around 80%), that feed the lake, come with the Ili River that is born on the Chinese side. Most of the water is used for agriculture purposes. Now the Chinese Government want to increase the irrigated area and develop more projects that require more water. If this is done without any improvement in the agriculture management, the IBB is under threat. The irrigation systems in the study area are very precarious. The farmers are isolated with almost no possibility to participate in the development process. The government is not interested in any research in water issues and the information that can be found about water consumption and cultivated area are proven to be far from reality. A difficult situation facing the above mention problematic. The agriculture area can grow but the water management in the Upper Ili Basin needs to be reviewed and improved. Just by doing small changes like changing rice cultivation for a crop with a higher water productivity the amount of water that can be saved is considerable. Or by importing virtual water from a region with a higher water productivity. But first a general recognition from the Chinese side about water shortage is necessary. The Ili Balkhash Basin can be sustainable if it is treated as a whole. The boundaries of the system need to be set around the whole basin. A partial view of the basin can be dangerous and jeopardize the subsistence of the natural environment of the area. When the carrying capacity of the basin is measured, the only way to grow is under this threshold. In this case, by improving water productivity with better agriculture management.

Satellite derived data has become an essential input in hydraulic modelling. Digital ElevationModels (DEMs) derived from different sources through remote sensing techniques have become a powerful tool for poorly gauged regions. This paper analyses the capabilities of DEMS derived from Shuttle Radar Topography Mission (SRTM) and a Light Detection and Ranging (LiDAR) and compares their accuracy against each other in a 1D hydraulic model. The study tests two different methods for inferring the river bathymetry under the water surface level for the SRTM derived DEM in order to enhance its performance, the study further analyze the reliability of remotely sensed altimetry data derived from different satellite missions (TOPEX and ENVISAT) and its suitability to complement spaceborne topographic data in hydraulic modelling.

Résumé :
This dissertation encompasses two studies: one developing virtual field trips for mobile devices for an innovative approach to lower-division geoscience education, and the other examining the role of rock strength in river erosion and landscape evolution. The education study involves the development of three virtual field trip modules (Geologic Time, Geologic Structures, and Hydrologic Processes, all free on iTunes and Google Play) that lead students down a virtual Colorado River through Grand Canyon by physically moving around their campus quad, football field or other location, using their GPS-equipped smart phone or tablet. As students reach each location in the scaled down and geo-referenced virtual Grand Canyon, an informative video appears with a themed geological question and an interactive touchscreen activity. The effectiveness of these three modules in terms of student engagement and learning was tested at five U.S. Colleges with a range of missions and student demographics. Results show that the virtual field trip modules are effective at increasing student interest across races and genders in the geosciences, do not detract from student learning, and have the potential to increase content comprehension. The second study is the examination of the relation between rock strength and topography in the Colorado Plateau. This work contributes empirical data to the age-old debate over the mechanisms and patterns of stream erosion through statistical relations between rock strength and stream power, river steepness, and valley width along the Green-Colorado River system. Estimates of an “effective” tensile strength were calculated for units too incompetent to test directly, such as the shales prevalent in the region. Results indicate bedrock strength is a first-order control on river erosion in this landscape, as suggested by John Wesley Powell in 1896: “where the rocks are firm and stable, corrasion [sic] of the stream is slow; where the rocks are soft, corrasion [sic] is more rapid,” which is intuitive yet frequently overlooked.

Résumé :
Estimating the bed material transport in large gravel-bed rivers represents a challenging task. Among the alternatives to achieve estimates of such key process, the virtual velocity approach represents one of the most promising possibilities. The research aims at improving the virtual velocity approach and at evaluating the reliability of its transport estimates using an independent and robust procedure as the morphological method applied at the same dam-regulated study sector of the Parma River (Italy). After field and remote sensing data collection, we performed the coarse sediment transport calculations using the two selected approaches and compared the estimates obtained at the same river cross-sections. Since the two methods provided remarkably similar transport results over the period April 2016 - April 2017, the virtual velocity approach can be considered as a viable tool for achieving reliable bed material load estimates in large gravel-bed rivers.
La stima del trasporto del materiale grossolano costituente il letto dei corsi d’acqua ghiaiosi di grandi dimensioni rappresenta un’attività complessa. Fra le diverse possibilità per conseguire tale obiettivo il metodo della “velocità virtuale” costituisce una delle opzioni più promettenti. Il presente lavoro di ricerca mira al miglioramento di tale approccio e alla valutazione dell’affidabilità delle stime da esso fornite utilizzando quale termine di confronto i risultati forniti dall'applicazione di un robusto “metodo morfologico” applicando entrambi le metodologie al medesimo settore studio posto a valle di una diga che regola il flusso del Torrente Parma (Italia). A seguito della raccolta di dati in campo e attraverso tecniche di telerilevamento è stato eseguito il calcolo del trasporto solido grossolano mediante le due metodologie selezionate e sono state confrontate le stime ottenute in corrispondenza di quattro sezioni-studio. I risultati ottenuti risultano essere significativamente simili per il periodo Aprile 2016 - Aprile 2017, permettendo di concludere che il metodo della velocità virtuale rappresenta un’alternativa affidabile per stimare il trasporto solido grossolano in corsi d’acqua ghiaiosi di grandi dimensioni.

Texte intégral
Résumé :
Operating hydropower reservoirs with small storage capacity is a challenging task due to the fact that in a watershed system there usually exist multiple stakeholders with different and conflicting preferences and values. Consequently the process of planning for reservoir operation must be carried out with consideration of several, usually competing, objectives. This process becomes even more challenging during a high inflow or flooding event for three main reasons. First, the objective of minimizing adverse consequences of such an event is added to the set of objectives that the operator must deal with. Second, inflow forecast uncertainty-driven risks are highly intensified due to the high sensitivity of the outcomes to inflow forecasts. And third, the available time for making a decision is very short while comprehensive analysis is a necessity in order to make an informed decision regarding the best operational alternative. Under these circumstances, the best approach to confront this challenge could be developing a Risk-Informed Decision Making (RIDM) framework that provides operation planning engineers with a solid and pre-designed guideline to deal with the task of identifying the best operational alternative in an efficient and timely manner. The current study is an attempt to apply the virtual structure of a RIDM framework for the Cheakamus River system in British Columbia. The framework is a coherent assembly of a number of methods and tools we have either developed or utilized from the existing widely used methods and techniques in practice. The product of our work is an example of the necessary tools that need to be used to develop recommendations for operating Daisy Lake reservoir during a high inflow event in a manner that all the operational objectives are served in the best possible way. This is done while taking into account making trade-offs among competing objectives. We illustrate the practical applicability and merits of the framework through applying it to a historical high inflow period in October 2003. The outcome is near real-time decisions with less dependency on only planners’ judgement and more dependency on thorough and systematic analysis with consideration of human judgement and possible risk tolerances.

Résumé :
Stephen’s musings on the pre-cinematic ‘stereoscope’ are discussed in relation to Bloom’s contemplation of parallax and his mention of the ‘Mutoscope’. The three-dimensionality, tangibility, and tactility of stereoscopic perception is analysed alongside Bloom’s and Gerty’s encounter in ‘Nausicaa’ and the Merleau-Pontian concepts of ‘flesh’ and ‘intercorporeity’. The bodily effects of projected cinema—achieved through virtual film worlds, virtual film bodies, and the intercorporeity of film and spectator—are discussed through reference to panorama, phantom ride, and crash films. The dizzying effects of some of these films are compared to the vertiginous nature of the ‘Wandering Rocks’ episode of Ulysses; these cinematic and literary vestibular disturbances are elucidated through gestalt theory and the phenomenological concepts of ‘intention’, ‘attention’, and the ‘phenomenal field’. Finally, the relationship between the self and the other is considered, through a discussion of cinematic mirroring in Ulysses and in Mitchell and Kenyon’s fin de siècle Living Dublin films.

Résumé :
European statistics show that motorbikes road accidents are extremely high and the reduction of such accidents is one of the main concern for the European community. Advanced Driver Assistance Systems are safety electronic systems used to assist the driver in avoiding risks and road accidents, by means of warnings sent before the situation becomes critical. The use of such systems in motorcycle context is currently lacking due to numerous variables that it is necessary to consider for making sure the riding. This paper presents an innovative research for the safety improvement of Powered-Two-Wheelers (PTW) by means of the development of effective and rider-friendly interfaces and interaction elements for the on-bike assistance systems. In particular, the paper presents the experimental results on comfort and safety aspects of two advanced rider assistance systems: the Frontal Collision Warning (FCW) and the Lane Change Support (LCS). The study starts from analyzing results of motorcycle simulator tests performed in 3D Virtual Reality environments which aim is to find recursive rider’s behavior patterns in FCW and LCS situations according to different multimodal type of warnings (visual, audio and haptic). Afterward, the paper presents three different machine learning models, Hidden Markov Models, Support Vector Machines and Artificial Neural Networks, that have been considered for simulating the riders’ behavior patterns according to the reaction time needful for avoiding a front collision. These simulation behavior models enabled to design a warning delivery strategy for apprising the rider of possible dangerous situations due to front collisions. Finally, the paper describes how this warning delivery strategy has been implemented in a HMI (Human Machine Interface) installed on motorbikes. This HMI is thought to offer an effective FCW system based on an understandable but, at the same time, discreet and unobtrusive rider-friendly solution.

Résumé :
Multibody dynamics simulation technology can provide a great help to understand and analyze motorcycle dynamics. In fact, its application in this field has grown very fast in the last years. However, apart from the mathematical model of the vehicle, a virtual rider is essential in order to properly simulate a motorcycle. This is due to the unstable nature of two-wheeled vehicles, which makes them very difficult to simulate by using open-loop maneuvers. The problem of developing a virtual rider for motorcycles has already been covered in literature but most of the proposed control algorithms achieved their purpose without considering the physiological limits of the rider. The objective of the research activities presented here are the preliminary development of a realistic virtual rider based on an experimental campaign and its subsequent simulation together with a detailed multibody model of a motorcycle. Special emphasis was put on making the rider model as simple as possible to facilitate the posterior design of the controller. Real rider movements were measured under laboratory conditions by means of the Motion Analysis technique. Several volunteers with different riding experiences, gender and anthropometry were involved in the experiments in order to provide a valid dataset for the analysis. For the present research, the virtual rider controls the direction of the motorcycle by means of both a torque on the handlebars and the movement of his body. The upper part of the rider’s body was modeled as an inverted pendulum. With regard to the longitudinal dynamics, the motorcycle is controlled by means of the brake torques and by the engine torque, which is transmitted to the rear wheel by means of a simplified model of the chain. First results of the developed virtual rider are presented at the end of this paper.

Résumé :
In this paper, three motorcycle models of increasing complexity are introduced. The first, and most simple, can be considered an extension of the model developed by Neil Getz in which the non-holonomic constraints have been removed to take into account the sideslip in tires. Also, this model can be viewed as an extension of the popular bicycle model, widely used in analyzing car dynamics. It has been extended with an additional degree of freedom essential to study motorcycle dynamics: the roll angle. Such a model, simple yet detailed enough, will be used as the basis in the development of a virtual rider. The second model is much more complex than the previous one. It includes the real geometry of the steering system and circular tire profiles which greatly increases the size of the equations. This is a multibody model of a complete rigid motorcycle (i.e. it has no suspensions) consisting of 4 bodies: rear wheel, main frame, fork and front wheel. The last model incorporates the front and rear suspensions together with all the features of its predecessor. It has 13 degrees of freedom, 11 of the mechanical system and 2 of the tire relaxation equations. It will be used as a full model for simulation and rider validation. The models presented in this article have been developed using Maple mathematical software which allows symbolic manipulation of equations. Thus, with this set of models, one can study in depth the phenomena that govern motorcycle dynamics since all the equations are available symbolically.

Texte intégral
Résumé :
A bond graph model of a fully suspended mountain bike and non-seated rider is created to develop predictions for the performance of mountain bikes during large excursion maneuvers such as drops, jumps, crashes, and rough terrain riding. The model assumes planar dynamics, a single pivot full suspension bicycle, and a rigid-body rider suspended from the bicycle. The main frame, front fork, rear triangle, two wheels, and rider are modeled as separate bodies interconnected at the main pivot, telescoping fork, pedals, handlebars, and axles. Suspensions are between the main frame and front fork, main frame and rear triangle, handlebars and rider (arms) and pedals and rider (legs). An algorithm is used to allow tracking of a virtual tire-ground contact point for events that separate the wheels from the ground. Significant excursions of motion are allowed to model major slope changes, separations from the ground, and large rotational events (endos). The bond graph approach allows kinematics to drive the significant dynamic interactions with the effort (force and torque) relationships being derived for “free”. Simulations of a ground profile with a rise followed by a steep drop are performed for various initial conditions to qualitatively validate the predictions of the model. Rider strategies for negotiating the drop are examined in the process. Overarching goals of the research are to examine and understand the dynamics and control of interactions between a cyclist and mountain bike. Specific, longer term, goals are to understand the improvement in performance afforded by an experienced rider, to hypothesize human control algorithms that allow riders to perform maneuvers well and safely, to predict structural bike and body forces from these maneuvers, and to quantify performance differences between hard-tail and various full suspension bicycles.

Résumé :
CIRA has recently set up a research and development project with Italian industrial partners, with the aim of develop hot structures based on ceramic matrix composites technology (C-C/SiC), code named SHS-CMC project. The project focuses on the application of the technology on the control surface of a re-entry vehicle, with the final objective of reaching TRL 5/6, to be spent in more challenging projects such as ESA SPACE RIDER. Thanks to CIRA heritage on ESA EXPERT flap plasma wind tunnel testing, the demonstrator of SHS-CMC project technology will be based on the EXPERT flap geometry, to be tested for final TRL assessment, in more demanding environment such as those of ESA-SPACE RIDER atmospheric re-entry phase. Besides the manufacturing process development it is of paramount importance to have robust and reliable thermal-mechanical models for design, in which both the material anisotropy and the most representative heat transfer phenomena are modelled and validated through test. In the present work the thermal model of the technological demonstrator has been set up. The validation of the model has been obtained trough numerical experimental correlation of PWT test on a similar test article developed in the frame of ESA EXPERT project. The virtual test shows good agreement with experiments in terms of temperature maps. This is the first step to be accomplished before the final qualification test and numerical-experimental validation of the SHS-CMC technology demonstrator, and subsequent TRL assessment.

Texte intégral
Résumé :
The main recommendations of the panel report can be summarised under four headings: 1. From Source to Sea: River systems, from their source to the sea and beyond, should form the focus for research projects, allowing the integration of all archaeological work carried out along their course. Future research should take a holistic view of the marine and maritime historic environment, from inland lakes that feed freshwater river routes, to tidal estuaries and out to the open sea. This view of the landscape/seascape encompasses a very broad range of archaeology and enables connections to be made without the restrictions of geographical or political boundaries. Research strategies, programmes From Source to Sea: ScARF Marine and Maritime Panel Report iii and projects can adopt this approach at multiple levels; from national to site-specific, with the aim of remaining holistic and cross-cutting. 2. Submerged Landscapes: The rising research profile of submerged landscapes has recently been embodied into a European Cooperation in Science and Technology (COST) Action; Submerged Prehistoric Archaeology and Landscapes of the Continental Shelf (SPLASHCOS), with exciting proposals for future research. Future work needs to be integrated with wider initiatives such as this on an international scale. Recent projects have begun to demonstrate the research potential for submerged landscapes in and beyond Scotland, as well as the need to collaborate with industrial partners, in order that commercially-created datasets can be accessed and used. More data is required in order to fully model the changing coastline around Scotland and develop predictive models of site survival. Such work is crucial to understanding life in early prehistoric Scotland, and how the earliest communities responded to a changing environment. 3. Marine & Maritime Historic Landscapes: Scotland’s coastal and intertidal zones and maritime hinterland encompass in-shore islands, trans-continental shipping lanes, ports and harbours, and transport infrastructure to intertidal fish-traps, and define understanding and conceptualisation of the liminal zone between the land and the sea. Due to the pervasive nature of the Marine and Maritime historic landscape, a holistic approach should be taken that incorporates evidence from a variety of sources including commercial and research archaeology, local and national societies, off-shore and onshore commercial development; and including studies derived from, but not limited to history, ethnology, cultural studies, folklore and architecture and involving a wide range of recording techniques ranging from photography, laser imaging, and sonar survey through to more orthodox drawn survey and excavation. 4. Collaboration: As is implicit in all the above, multi-disciplinary, collaborative, and cross-sector approaches are essential in order to ensure the capacity to meet the research challenges of the marine and maritime historic environment. There is a need for collaboration across the heritage sector and beyond, into specific areas of industry, science and the arts. Methods of communication amongst the constituent research individuals, institutions and networks should be developed, and dissemination of research results promoted. The formation of research communities, especially virtual centres of excellence, should be encouraged in order to build capacity.
