Abstract:

In recent years, waterway governance has become an opportunity for a new round of reform to urban waterfront space. In the new historical conditions, affected by the requirements of ecological restoration of waterways and urban waterfront landscape, the improvement of the water quality, the functional transformation of waterfront space and comprehensive improvement in the shoreline environment are hold together by the guide of principles of sustainable development. Based on waterway governance, the urban waterfront space is becoming into the important meeting point of the improvement of urban environment, space and the quality of the culture. In this paper, the planning of urban waterfront based on Anhui Nanfei River waterway governance is discussed.

Abstract:

Natural environments, such as inland waterways (IWs), have been identified as a potential means to increase physical activity and promote health and wellbeing. However, further information on predictors of IW usage and their relationship with health and wellbeing outcomes is needed. Data were taken from the cross-sectional UK Waterways Engagement Monitor survey of waterway users (n = 21,537) in 2019/2020. Health outcome measures were life satisfaction, physical activity, and mental wellbeing. Visit frequency was an additional outcome measure. Both bivariate and multivariable associations between outcome measures and features of IWs were explored. The travel-cost method was used to estimate users’ demand, expressed by travel costs to waterways. Multivariable models showed positive associations of frequent visits and use for recreational/leisure purposes with life satisfaction and physical activity. Rural visits were associated with higher life satisfaction than urban ones. Lower visit satisfaction negatively impacted life satisfaction and mental wellbeing. Visit frequency was influenced by individual characteristics and purpose of visit, including visits for exercise. Waterway visits were inversely associated with travel costs (IRR = 0.99, p-value ≤ 0.001), and there was greater demand elasticity for short distances (≤5 miles). Socioeconomic-related inequalities were present. Future policies could enhance frequent use of waterways and alleviate accessibility-related inequalities to improve population health outcomes.

Abstract:

Waterways can contribute to the beauty and livelihood of urban areas, but maintaining their hydro-ecosystem health is challenging because they are often recipients of contaminated water from stormwater runoff and other discharges. Public awareness of local waterways’ health and community impacts to these waterways is usually poor due to of lack of easily available information. To improve community awareness of water quality in urban waterways in New Zealand, a web portal was developed featuring a real-time waterways monitoring system, a public forum, historical data, interactive maps, contaminant modelling scenarios, mitigation recommendations, and a prototype contamination alert system. The monitoring system featured in the web portal is unique in the use of wireless mesh network technology, direct integration with online modelling, and a clear target of public engagement. The modelling aims to show the origin of contaminants within the local catchment and to help the community prioritize mitigation efforts to improve water quality in local waterways. The contamination alert system aims to keep managers and community members better informed and to provide a more timely response opportunity to avert any unplanned or accidental contamination of the waterways. Preliminary feedback has been positive and is being supported by local and regional authorities. The system was developed in a cost-effective manner providing a community focussed solution for quantifying and mitigating key contaminants in urban catchments and is applicable and transferable to other cities with similar stormwater challenges.

Abstract:

Descriptions of shifts in biodiversity across time are desired for urban freshwater systems to better study ecosystem change and causal mechanisms. I document changes in fish diversity within the Chicago Area Waterways across 35 years using a battery of diversity metrics calculated on both abundance and biomass data. Has diversity of Chicago's waterways changed over 35 years and if so, do different diversity metrics exhibit different trends or breakpoints in trends? Diversity of the fish assemblage increased across the three decades of study. Breakpoint analysis suggested that trends across the timeseries were nonlinear. Changes in dominant species influenced behavior of less traditional metrics, whereas Margalef's Richness, Shannon-Weiner, and Gini-Simpson appeared more robust. Increases in richness and taxonomic diversity combined with decreases in species dominance suggest an ecosystem of increasing quality. The fish community of the Chicago Area Waterway System is more diverse both in abundance as well as biomass (i.e., energy flows) in the late 2010's than it was in the late 1980's. Although external factors related to wastewater treatment increased water quality and likely led to these assemblage-level changes breakpoint analysis did not allow verification of causal mechanisms.

Abstract:

In Melbourne, Australia, the adoption of Water Sensitive Urban Design (WSUD) and the inclusion of best practice in new urban development has shifted the “drained city” of the 1960s toward an environmentally-oriented “waterways city” for the future. However, the “waterways city” is tenuous owing to the variable commitment of local municipalities to WSUD. This paper reports on the first phase of a social research project, which aims to secure a model of the waterways city by addressing the commitment and capacity deficits of local municipalities. Municipal commitment and capacity across three geographical areas in Melbourne are measured quantitatively using an innovative, comprehensive, and replicable assessment technique. The results show variability in municipal capacity and commitment across the areas, with a pronounced deficit in the rural-regional area. Consequently, intergovernmental attempts to normalise modes of integrated urban water management (such as WSUD) need to include innovative and flexible mechanisms that are responsive to the dynamics of municipal commitment and capacity. These principles have broader application to cities internationally where the management of urban stormwater is the shared responsibility of multiple governments.

Abstract:

When the wastewater volume exceeds the sewer pipe capacity during extreme rainfall events, untreated sewage discharges directly into rivers as combined sewer overflow (CSO). To compare the impacts of CSOs and stormwater on urban waterways, we assessed physicochemical water quality, the 16S rRNA gene-based bacterial community structure, and EcoPlate-based microbial functions during rainfall periods in an urban waterway before and after a stormwater storage pipe was commissioned. A temporal variation analysis showed that CSOs have significant impacts on microbial function and bacterial community structure, while their contributions to physicochemical parameters, bacterial abundance, and chlorophyll a were not confirmed. Heat map analysis showed that the impact of CSO on the waterway bacterial community structure was temporal and the bacterial community composition in CSO is distinct from that in sewers. Hierarchical clustering analysis revealed that the waterway physicochemical water qualities, bacterial community composition, and microbial community function were distinguishable from the upper reach of the river, rather than between CSO and stormwater. Changes in the relative abundance of tetracycline resistance (tet) genes—especially tet(M)—were observed after CSOs but did not coincide with changes in the microbial community composition, suggesting that the parameters affecting the microbial community composition and relative abundance of tet genes differ. After pipe implementation, however, stormwater did not contribute to the abundance of tet genes in the waterway. These results indicate that CSO-induced acute microbial disturbances in the urban waterway were alleviated by the implementation of a stormwater storage pipe and will support the efficiency of storage pipe operation for waterway management in urban areas.

Abstract:

High prevalences of liver neoplasms have been found in English sole (Parophrys vetulus) from urban waterways of Puget Sound, Washington. Although the etiology of these neoplasms is not known, evidence suggests that chemical contaminants may be the causative agents. Electron microscopy studies were undertaken to investigate subcellular structures of hepatocellular carcinomas from these fish.English sole were collected by otter trawl from several urban waterways of Puget Sound, Washington State. Grossly visible liver nodules were excised from freshly killed fish and divided for light and electron microscopy. Tissues for light microscopy were processed by standard histological procedures, and stained with Hematoyxlin and Eosin.

Abstract:

Inland navigation is hardly ever used to transport cargo in cities. In most urban areas, it is performed almost exclusively via road transport, with the virtual exclusion of rail and inland transport. Research and implementation projects in several European cities have shown that employing inland navigation is a viable alternative for road transport in urban areas. The research involved a case study of transporting the same number of 40-foot containers by inland waterway and road and then comparing the results in terms of transport time, transport costs, and carbon dioxide emissions between two metropolitan areas in Poland. The article shows that River Information Services (RIS) system can contribute to improving freight transport efficiency not only on longer routes, but also in urban and inter-urban conditions. The findings were that inland shipping is much cheaper and more environmentally friendly, but transport takes much longer and is not always possible due to insufficient waterway infrastructure. The paper can be used as a road map to proceed with new approach to planning urban and inter-urban logistics, with the use of inland navigation supported by the RIS system. The study delivers evidence that the main benefits of using RIS for urban logistics are: optimization of the cargo route, improved supervision and control of cargo transport, optimization of inter-branch transport, optimization of the use of fleet, more efficient use of technical infrastructure of waterways, combination of many recipients/senders into one transport, and reduction of administrative barriers.

Abstract:

Owing to new regulations starting from 2025, all commercial canal boats have to comply to zero local emission standards in Amsterdam. It is therefore vital that a clear emission indicator is made available for vessels with a varying operational profile, such as canal boats. In this paper, it is argued that current indicators, such as the Energy Efficiency Design Index, are not suitable for these (passenger) vessels. This paper proposes environmental performance indicators that can quantify emissions, (non-dimensional) energy and fuel usage based on an operational profile set in the design phase. This profile includes part load operation and auxiliary consumers and it can compare new designed concepts with current baseline vessels based on the ‘benefit for society’ of different vessel types. In the proposed environmental performance indicators, several operational modes can be defined, in contrast with the currently proposed Energy Efficiency Design Index, which is a point index at 75% of installed power. To gauge not only local emissions but also global emissions, the environmental performance indicator methodology is used to determine a minimum efficiency from any power generation method. This minimum efficiency follows from a comparison between baseline vessels and concepts that are more energy efficient and emission friendly. The proposed environmental performance indicators were validated using measurements on typical propulsion configurations of canal boats in Amsterdam. Three full electric concepts were designed and compared with the measured baseline vessels. As full electric concepts do not have local emissions, the method of power generation must satisfy the requirement to have less global emissions than the mechanical baseline. Furthermore, an energy efficiency of at least 33% is calculated from a fossil-fuelled land-based power plant (including transport) to the boundary from quay to boat to be required for newly designed electric concepts to be more energy efficient than the mechanical baseline.

Abstract:

The urbanization process indicates that today’s cities are the main centres where transport demands accumulate. This causes, in effect, an increase in freight and passenger traffic, which in turn contributes to a rise in environmental and noise pollution, accidents, and thus a deterioration of the quality of life in cities. Bearing in mind the numerous advantages of inland waterway transport, it can be assumed that in cities located near inland waterways, this branch can be seen as an important link in the urban logistics chain. Therefore, the aim of this article is to indicate the possibility of using this mode of transport to handle transport needs in cities. Thearticle uses the method of desk research, based on analysing andverifying facts and merging existing statistical data on the urbanization process and experiences related to the use of inland waterway transport to handle various transport needs in selected European cities. The article shows that in cargo transit, the use of inland waters in urban logistics is an attractive branch of transport, not only in such areas as transportation of construction materials or waste collection but also in transport related to the supply of stores. Positive experiences of Western European cities should inspire action to increase the use of this branch in urban logistics in Poland, e.g., in the city of Gdańsk, located above the Motława waterway.

Abstract:

It is often difficult today to appreciate the important role that waterways played in the development of Edo-Tokyo. For most of the city's history, however, they have been fundamental to its economic prosperity and its cultural landscape. In this chapter, I focus on the city's main river, the Sumida, and the waterways that drain into it from its east bank, away from the centre of the city. During the Edo period, the east bank presented space for urban expansion. Its many waterways provided extra capacity for the offloading of goods and provisions and the establishment of marketplaces. Indeed, the ubiquity of water and waterways meant that the east bank became the principal site of industrialisation and the problems that accompanied it. Here I take a longitudinal look at the Sumida and the east bank's waterways. I start with a brief introduction to water and land in the city's early years. The bulk of this chapter explores the development of waterways and activities along their banks in the XIX and early XX centuries, bridging the change from shogunal to imperial rule. This long temporal span throws a number of changes into relief. The first is the nature of the documentary material, whose nature and idiom changes radically through this period. Second is the process of urbanisation and later of industrialisation that occurred as the east bank became ever more densely populated. The third relates to the waterways themselves, vital to the provisioning of the city, arena of recreation but also source of pollution.

Abstract:

The value of natural heritage within urban areas is nowadays gaining recognition, but there are still no clear reference frameworks to confront the complexities of their management. In this discussion, the challenges of the association of historical preservation and urban nature are explored through the analysis of the management of Kyoto’s waterways. The conflicts caused by the rapid modernization of Japan at the end of 19th century find in Kyoto a remarkable expression in the tensions between renovation and conservation, providing a fertile frame for discussion. Relevant achievements and shortcomings of Kyoto´s experience are here analyzed, considering how the preservation of historic landscapes affected the protection of urban rivers, the relationship between sustainability and heritage, and the new environmentally aware approaches to river improvement.

Abstract:

The waterways of South East Queensland, Australia, represent unique and complex ecosystems that have a high conservation value and support major recreational and commercial fisheries. The agricultural districts of the region also contribute significantly to the regional economy and, together with the growing urban areas, are heavily reliant on good quality water supplies. However, the human footprint of these activities has led to significant changes in catchment hydrology and sediment delivery, declining water quality and loss of aquatic biodiversity. Predicted population increases in the region are likely to further impact on the ecological and economic health of its waterways and catchments, and there are growing community expectations to reverse the decline in water quality and ecosystem health. In response to these concerns, government, industry and community stakeholders have worked in close cooperation to develop a whole-of-government, whole-of-community approach to understanding and managing the region's waterways. This paper provides an overview of the experience gained through development of the SEQ Healthy Waterways Partnership and highlights some of the key factors we believe have contributed to its success.

Full text

Abstract:

In amphibians, abnormal metamorph sex ratios and sexual development have almost exclusively been considered in response to synthetic compounds like pesticides or pharmaceuticals. However, endocrine-active plant chemicals (i.e. phytoestrogens) are commonly found in agricultural and urban waterways hosting frog populations with deviant sexual development. Yet the effects of these compounds on amphibian development remain predominantly unexplored. Legumes, like clover, are common in agricultural fields and urban yards and exude phytoestrogen mixtures from their roots. These root exudates serve important ecological functions and may also be a source of phytoestrogens in waterways. I show that clover root exudate produces male-biased sex ratios and accelerates male metamorphosis relative to females in low and intermediate doses of root exudate. My results indicate that root exudates are a potential source of contaminants impacting vertebrate development and that humans may be cultivating sexual abnormalities in wildlife by actively managing certain plant species.

Abstract:

Due to increasing population and expansion of cities, urban planning issues are becoming more important worldwide. It is realized that biological methodologies ought to be coordinated into urban arranging activities. Particularly in European cities, creating greenways and green corridors is a very recent phenomenon. The advancement of green space along urban waterways could moderate urban warmth island impacts, improve the physical and mental prosperity of city occupants, improve flood resilience and could also sustain biodiversity. The Pedieos River is the longest river in Cyprus. Like most of streams on the island, it is a non-enduring waterway, of fleeting nature that for the most part streams during the blustery winter months or after overwhelming precipitation occasions. A literature review was undertaken to discover the importance of rivers within the urbanized areas. It is known that the Pedieos River is firmly connected to the historical backdrop of Nicosia as it is one reason for the city's presence at the site. The increase of impermeable areas as a result of urbanization is also one of the main causes for flooding in recent years. In this research, the current situation of the river was investigated and its possible rehabilitation discussed for more sustainable city. The aim of this study is to recommend a feasible proposition by examining green territory zones and reason green passages along the Pedieos River so as to improve the living condition of Nicosia city.

After studying the morphometric analysis of the waterways of the fan, the role of the natural factors represented by tectonic, geological, climate and hydrology was highlighted in the occurrence of torrents, which are among the most severe, The geomorphological hazards affected by urban facilities, agricultural lands and road networks on the surface of flood fans. The total number of waterways reached (948) streams ،And the total lengths of the waterways amounted to (446689) m. Three channels of waterways appeared on the surface of the Rani flood fan, which are the bed rocks channel pattern, the semi-dominant channel pattern, and the alluvial channel pattern. The research found that the flow risk values fall within the first category of the final classification table for the equations of the (Filmman) model with the risk value (High), which represented the dangerous flood areas, where it appeared that the expenditures at the points (q1, q2, q3) fall within the high-risk drainage According to the final classification of the Felman equations Where their expenses

Abstract:

Water pollution is a persistent problem in China, in part, because local governments fail to implement water quality standards set by national and provincial authorities. These higher authorities often lack regular information about the immediate and long-term achievement of remediation targets. Accordingly, central authorities have encouraged nongovernmental organizations to monitor local governments’ remediation efforts. This study examines whether nongovernmental monitoring of urban waterways improves water quality by facilitating oversight of local governments or instigating public action for remediation. We randomly assigned urban waterways in Jiangsu province previously identified for remediation to be monitored by a partner nongovernmental organization for 15 mo. We further randomized whether the resulting information was disseminated to local and provincial governments, the public, or both. Disseminating results from monitoring to local and provincial governments improved water quality, but disseminating results to the public did not have detectable effects on water quality or residents’ pursuit of remediation through official and volunteer channels. Monitoring can improve resource management when it provides information that makes local resource managers accountable to higher authorities.

Abstract:

Traffic congestion is an enormous problem at peak hours in western province. Existing transport system is not capable to overcome these complexity situations. Therefore, Srilankan government needs to find out different mode of transport to save time and money and finally economy of the country. In the past history, there was a rich water transportation system over the country. Specially, the western province has a well-distributed network of inland waterways, comprising of main rivers, streams, canals, lakes, and tanks. Most of the time, the existing waterways were used for freight transportation (timber, sand, brick, and tiles. compare to Public transportation. The study is to determine the efficient use of waterways for the public transportation focusing the travel time and fuel consumption. The existing water way network was map and find availability of other network connectivity using ArcGIS and Google Earth Pro software. Then compare it with an existing public transportation mode (bus) and checked the suitability of usage of water transportation as an alternative to reduce the existing traffic congestion problem. And proposed water way transport system, that capable of potential and strategic way to reduce the traffic congestion problem in Colombo and its sub urban areas.

Abstract:

Abstract Illicit discharges in urban stormwater drains are a major environmental concern that deteriorate downstream waterway health. Conventional detection methods such as stormwater drain visual inspection and dye testing have fundamental drawbacks and limitations which can prevent easy location and elimination of illegal discharges in a catchment. We deployed 22 novel low-cost level, temperature and conductivity sensors across an urban catchment in Melbourne for a year to monitor the distributed drainage network, thereby detecting likely illicit discharges ranging from a transitory flow with less than 10 minutes to persistent flows lasting longer than 20 hours. We discuss rapid deployment methods, real-time data collection and online processing. The ensemble analysis of all dry weather flow data across all sites indicates that: (i) large uncertainties are associated with discharge frequency, duration, and variation in water quality within industrial and residential land uses; (ii) most dry weather discharges are intermittent and transient flows which are difficult to detect and not simply due to cross-connections with the sewerage network; (iii) detectable diurnal discharge patterns can support mitigation efforts, including policies and regulatory measures (e.g., enforcement or education) to protect receiving waterways; and, (iv) that it is possible to cost effectively isolate sources of dry weather pollution using a distributed sensor network.

Abstract:

Abstract As the world moves towards urbanization, the demand for land for urban land use increases. If left unmanaged, this might result in the wastage of land that could have been used for more productive purposes, such as agriculture. Other developments can also pose risks to the environment and to those who inhabit it. Therefore, land suitability analyses must be carried out before proceeding to urban planning. This study produced an urban suitability analysis of the municipality of Diffun in Quirino Province as a basis for future urban planning. Conducting this analysis will be very timely, considering that the revision of the municipality’s Comprehensive Land Use Plan (CLUP) will start in 2021. In this study, two methods of doing the analysis were integrated: Boolean overlay and weighted overlay. Using the gathered spatial data, a total of 18 factors and restrictions were produced for the analysis. Restriction layers used in the Boolean overlay method include existing built-up areas, erosion risk, flooding susceptibility, protected agricultural lands, other protected lands, Quirino Protected Landscape (QPL), slope, waterway buffers, and ecotourism site buffers. Meanwhile, the weighted overlay analysis used the following factors: elevation, land-use type, distance to ecotourism sites, distance to local roads, distance to national and provincial roads, proximity to the downtown, distance to protected agricultural lands, distance to waterways, and slope. The weights of the factors were calculated using a pairwise matrix. The study concluded that only 0.32% of the total land area of the municipality is most suitable for urban land-use, while 87.36% is considered not suitable for the development of built-up areas.

Abstract:

The study is carried in the framework of the project “Urban planning retrospective of medium and small settlements of the Ob-Yenisei waterway”, which is aimed at studying the transformation of residential areas of one of the main waterways of Siberia, from Tyumen to Kyakhta. The coastal territory of the Tura, Tobol, Irtysh, Ob, Ket rivers of the Ob basin in West Siberia is studied. The theoretical study identifies and graphically displays medium and small settlements at different development stages of West Siberia. A retrospective of the settlements allows to determine their typhology in the waterway coastal zone in the 18–19th centuries. The quantitative data on each type of settlement are obtained, and the routes of communication are classified. In the 18th century, land directions rarely cross the settlements, most of them locate along the rivers, streams, elders and lakes. In the 19th century, local residential areas (houses, single yards, settlements, villages) along the land routes enlarge and form villages. A comparative analysis shows a high percentage of preserving the location, typhology and planning structure of the small settlements of the modern settlement system. In general, the period of urbanization is described from the late 18th and early 19th centuries.

Abstract:

Andrea Palladio’s Venetian churches of San Giorgio Maggiore and Il Redentore overlook the Bay of San Marco and its tributaries, the Grand Canal and the Giudecca Canal. In Palladio and the Water-oriented Scenography of Venice, Daniel Savoy examines the churches from their surrounding waterways, explaining them as centerpieces in an elaborate program of urban scenography that must be seen as a work of collective civic authorship. Through close topographical and contextual analysis, he shows that Palladio and his patrons oriented the churches to be seen from the perspective of the waterways approaching and transversing the city while evoking the visual experience and cosmological associations of theater. The scheme accords with Palladio’s theoretical project but also builds on Venetian conventions of aquatic urbanism and symbolic geography, implicating the architect in a centuries-old tradition in which the mythical image of Venice was projected through the city’s spectacular waterfront architecture.

Abstract:

Urbanization degrades the hydrology and water quality of waterways. Changes to flow regimes include increased frequency of surface runoff, increased peak flows and an increase in total runoff. At the same time, water use in many cities is approaching, and in some cases exceeding, sustainable limits. Stormwater harvesting has the potential to mitigate a number of these detrimental impacts. However, excessive harvesting of stormwater could also be detrimental to stream health. Therefore, a study was undertaken to test whether typical stormwater harvesting scenarios could meet the dual objectives of (i) supplying urban water requirements, and (ii) restoring the flow regime as close as possible to ‘natural’ (pre-developed). Melbourne and Brisbane, which have different climates, were used along with three land use scenarios (low, medium and high density). Modelling was undertaken for a range of flow and water quality indicators. The results show that using these typical harvesting scenarios helped to bring flow and water quality back towards their pre-developed levels. In some cases, however, harvesting resulted in an over-extraction of flow, demonstrating the need for optimizing the harvesting strategy to meet both supply and environmental flow objectives. The results show that urban stormwater harvesting is a potential strategy for achieving both water conservation and environmental flows.

Abstract:

Research on sustainable transport and water projects, conducted in North America during 1999, identified four key considerations common to a number of projects. These four considerations are the pre-conditions necessary to achieve sustainability in a given location. These preconditions (BAPP) are boundary definition, administrative alignment, protection of non-urban lands, and the participation of all interested parties. This paper considers the perceived attitudes of various catchment stakeholders and focuses on planners and planning. The results of questionnaire surveys based on BAPP concepts suggest that local government is perceived as having the highest priority for protection of riparian lands and waterways (as individual Councils and Regional Organisations of Councils). Thus local government is the preferred arena for coordination, responsibility and jurisdiction of waterways and riparian land. The opportunity exists to examine the differing roles of local and state government. The paper concludes by outlining the implications of this research for land use planning and institutional structures in sustainable river management.
