The correct address of wave characteristics in the vicinity of submerged vegetation is crucial to perform an ecological analysis. Although several attempts have been done in the past using an analytical approach or depth averaged models, the rigidity of the assumptions used to solve the physics produced limited application to real cases. The use of a NS model called IH-2VOF is used first to minimize the number of predefined assumptions for wave propagation and the non-linear interactions between waves and plants and second to explore the possibility to improve existing turbulence models to consider wave interaction with vegetation. The IH2-VOF model has been validated using large scale experiments developed by Stratigaki et al. (2011). The model has shown a high degree of accordance between the lab data and the numerical predictions in free surface evolution. Numerical predictions of the velocity field have been compared both over and inside the vegetation showing also a high degree of accordance. Drag coefficients obtained during the model calibration are in accordance with previous studies such as Mendez et al. (1999). The influence of wave height, wave period, water depth and patch density have been studied using additional numerical simulations with irregular waves. Both the wave period and the water depth have been revealed as the most important parameters in the modification of the flow patterns around the patch.

Ecological impairment and flooding caused by urbanization can be expressed numerically by calculating the risks throughout the watershed (floodplain) and along the main stems of the streams. The risks can be evaluated in terms of the present and/or future. This article describes the methodologies for ascertaining the risks in the Geographical Information Systems (GIS) environment. The objectives of urban flood controls and ecological preservation/restoration of urban waters are often conflicting and, in the past, the sole emphasis on flood control led to destruction of habitat and deterioration of water quality. An optimal solution to these two problems may be achieved by linking the risks to the concepts of risk communication, risk perception, and public willingness to pay for projects leading to ecological restoration and ecologically sustainable flood control. This method is appropriate because, in each case, public funds are used and the projects require approval and backing of policy makers and stakeholders. This article briefly describes a research project that attempts to resolve the conflict between the flood protection and stream ecological preservation and restoration and suggests alternative ways of expressing benefits of urban stream flood control and restoration projects.

Annotation:

It is notable that of the environmental objectives of the Water Framework Directive (wfd), good ecological potential has been given less attention. The Weser case has made it possible to establish a more detailed understanding of ‘ecological potential’. An analysis indicates that the main approach to implementing ‘ecological potential’, the non-wfd mitigation-measure approach, creates discontinuity among the environmental objectives, which the wfd reference method does not. Even if the mitigation-measure approach accommodates enhancements, bodies of water are still not classified in accordance with the wfd. If a body of water is incorrectly classified, both good ecological potential and the non-deterioration prohibition should not be binding, as the ‘ecological status’ has not been determined. Furthermore, two different and uncoordinated forms of ‘ecological potential’ establish diverging quality standards, and risk legal uncertainty and inconstancy among Member States.

Based on the analysis of the current state of water resources and utilization characters, the optimizing and allocating model of water resources in Yinchuan plain is established by multi-objective planning methodology. Systematic viewpoint runs throughout the whole modeling process. Furthermore, by employing the established model, the proper allocation of the industrial and agricultural water, the ecological environment water and integrated development of surface water and groundwater are discussed. The more reasonable water utilization structure is suggested. The water resource for agriculture is decreasing, while the water resource for people life, industry and ecologic environment are increasing. This change of water utilization is correspond to economic and social development trend.

In the last 20 years, the EU has adopted some rather ambitious pieces of legislation with the aim to achieve a good environmental status in freshwater and marine ecosystems. Both the Water Framework Directive (WFD) and the Marine Strategy Framework Directive (MSFD) have a strong focus on the natural environment and biological criteria for assessing the status of the relevant ecosystems. In the same time period, much research on environmental governance has focused on the interconnectedness of social systems and ecosystems, so-called social-ecological systems (SES). While having high aspirations, the legal frameworks underpinning current EU water and marine management do not necessarily reflect the advances of contemporary science relating to SES. Using the geographical intersection of the two directives, i.e., coastal waters as a focal point, the paper explores the inchoate integration of social and ecological perspectives in the EU marine governance. What are the main challenges for the current EU legal regimes for managing coastal waters in a way that builds on the understanding of social and ecological systems as interconnected? Having explored the two directives, the paper introduces the possibility of using marine spatial planning (MSP), and the EU directive establishing a framework for maritime spatial planning (MSPD) as a bridge between the social and ecological dimensions and discusses what implications this would have for the current system for governing coastal waters in Europe.

Integrated Management of the Water Resources is nowadays a prerequisite for environmental preservation and economic growth. The EU Water Framework Directive provides the guidelines to develop strategies and institutions to protect and restore the water resources in both qualitative and quantitative bases. However, the implementation of the proposed measures incorporates significant difficulties arising from the lack of necessary data, the fragmented approach often followed in water management and the incomprehension of the interactions between hydrologic systems and ecological components. In this particular study, a combination of remote sensing data, hydrologic models, ecological assessment techniques, GIS software and isotopic surveys have been adopted to extensively study the water resources of Trichonis Lake catchment, in Western Greece, in order to develop management alternatives aiming at protecting ecologically significant wetlands and meeting the local irrigation demands. The management alternatives have been developed with the contribution of local authorities by redistributing the monthly water outflows from the lake according to the ecological and anthropogenic demands and comprise five plans that attempt to minimize the environmental impacts from the regional water use while maintaining the economic activities unaffected.

Management of land and water resources has emerged as a vital issue in promoting biodiversity and ecological security programmes. The basic message of ecological security is not of containing development to save ecology but of managing ecology to promote development. What is good for development is equally good for ecology. Developmentalists point out that development not only provides for all-round expansion of the economy but also brings capacity for improving the quality of ecology. Therefore the basic issue is that the wheel of development must move on but it should advance within the supportive capacity of the ecosystem. Any desired development should have the ingredients of efficiency, equity and democracy. When this is done the people tend to take ecology-friendly decisions. The validity of the above ideas is tested through a case study on Palar river basin. Management of Palar river basin against water pollution requires effective monitoring and implementation of protective measures not only for the management of water care but also for the land care as well. In doing so, this study analyses the grave problems posed by tannery effluents and suggest measures for achieving sustainable development, environment and livelihood security.

We present an independent assessment of the health and water sustainability of the East River (Dongjiang) in South China, which is the source of nearly 80% of Hong Kong's water supply. Field measurements show that the water quality in the upper and middle reaches is generally good and well exceeds the drinking quality standard, with high bio-diversity. The streamflow of the East River Basin is satisfactorily simulated using both the distributed MIKE-SHE model and the lumped HSPF model. With an average streamflow of 760 m3/s, the River is able to satisfy the current water demand. Using the HSPF model, the water quality is found to have deteriorated in recent years. In addition to water supply, the River also supports a variety of needs such as hydro-power generation, waste assimilation, navigation, habitat for aquatic life, and expulsion of sea water intrusion. Using the projected need of 150 m3/s for water supply, the instream flow requirement based on hydrological and water quality simulation is estimated to be 467 m3/s in 2010. This suggests that the water sustainability of the East River requires alternative strategies, which may include integrated water resources management, provision of better wastewater treatment, and water and soil conservation.

The article presents the results of the analysis of the main provisions of the concept of ensuring the ecological safety of settlements. The requirements for the water disposal system as a component of safe water use in settlements are determined in accordance with the principles of sustainable development. Scientifically based criteria formulated as components of sustainable development - ecological, social and economic-technological. The technologies of ecologically safe water disposal are theoretically justified and proposed. The sequence of the gradual conversion of the water disposal systems of a specific locality into an ecologically safe one was determined by selecting priority technologies for water disposal. A multi-criteria multi-level hierarchy of the choice of ecologically safe water disposal technologies has been developed, which has allowed the ecological sustainable functioning of a water body as an element of the environment. The program-analytical method for selecting priority technologies for ecologically safe water disposal, including the method of analyzing hierarchies to improve the quality of the results obtained in the formation of the decision-making process for the ecological safety management tasks of a particular settlement, was substantiated and tested. For specific localities, the priority of technology implementation was determined, the correct pairwise comparison was made with the achievement of the given level of consistency (ІY≤0.1 %). Based on this, it was determined that a reasonable choice for the implementation of priority technologies for ecologically safe water disposal can improve the ecological safety of eutrophic water bodies – sources of drinking water supply and recreational use and rise up the living conditions of residents of the settlements. Keywords: ecological safety, method for choosing environmentally sound wastewater technologies, settlement.

Purpose. The aim of the article is substantiation of the need to use the ecological and economic approach in the process of functioning of forestry, water, hunting in Ukraine. Methodology of research. The theoretical and methodological basis of writing the article are the fundamental provisions of economic theory, set out in the scientific works of domestic and foreign scientists on the efficiency (ecological and economic) use of forest, water resources and hunting grounds of Ukraine. General and special methods were used to solve certain tasks in the research process, in particular: analysis, synthesis, induction, deduction (to characterize the environmental and economic problems of forestry, water, hunting); abstract and logical (for the formation of conclusions and proposals on the need to use the ecological and economic approach and ecological rent as a direction of improving the ecological condition of forestry, water and hunting). Findings. It is argued that the economic, environmental, compensatory role of water and forest resources is growing, due to the man-made load on the environment in the world and in Ukraine. The content and algorithm of calculation of ecological rent as environment-forming value of forestry, water, hunting economy are determined. Problems of functioning and directions of development of forest, water, hunting economy are substantiated. Originality. Ecological and economic approach to the functioning of forestry, water, hunting in Ukraine was improved. This approach in contrast to the existing, allowed substantiating the need and developing an algorithm for using environmental rents as an environment of value of forest, water, hunting (monetary expression of ecological effect). Practical value. The use of the proposed ecological and economic approach allows to make informed decisions in the process of functioning of forestry, water hunting in Ukraine and to reduce the negative ecological consequences of nature management. Key words: forestry, water management, hunting management, ecological rent, ecological and economic approach, efficiency, nature management.

The Water Framework Directive (WFD) is a new legislative framework to manage, use, protect, and restore surface water and groundwater resources and coastal waters in the European Union (EU). The aim is to ensure sustainable water management and to reach good water quality by 2015. The assessment of the ecological status and setting of the practical management goals require several steps. The process has started with the characterisation of the river basins including identification of surface water bodies and types, and identification of significant anthropogenic pressures and impacts. The water bodies will be classified in five quality classes (high, good, moderate, poor, bad) based on the Ecological Quality Ratio, which is a ratio between reference conditions and measured status of the biological quality elements. The normative criteria for high, good and moderate ecological status described in the WFD need to be made operational because those will be used to set the practical quality targets for surface water management. National ecological assessment systems and classifications will be harmonised through the WFD intercalibration exercise in order to ensure an equal level of ambition in achieving good surface waters status all over Europe.

Abstract. Rebalancing water allocation between human consumptive uses and the environment in water catchments is a global challenge. The conventional water balance approach which partitions precipitation into evapotranspiration (ET) and surface runoff supports the optimization of water allocations among different human water use sectors under the cap of water supply. However, this approach is unable to support the emerging water management priority issue of allocating water between societal and ecological systems. This paper recast the catchment water balance by partitioning catchment total ET into ET for the society and ET for the natural ecological systems, and estimated the impacts of water allocation on the two systems in terms of gross primary productivity (GPP), in the Murray–Darling Basin (MDB) of Australia over the period 1900–2010. With the recast water balance, the more than 100 year water management in the MDB was divided into four periods corresponding to major changes in basin management: period 1 (1900–1956) expansion of water and land use by the societal system, period 2 (1956–1985) maximization of water and land use by the societal system, period 3 (1985–2002) maximization of water diversion for the societal system, and period 4 (2002–present) rebalancing of water and land use between the societal and ecological systems. The recast water balance provided new understandings of the water and land dynamics between societal and ecological systems in the MDB, and it highlighted the experiences and lessons of catchment water management in the MDB over the last more than 100 years. The recast water balance could serve as the theoretical foundation for water allocation to keep a dynamic balance between the societal and ecological systems within a basin for sustainable catchment development. It provides a new approach to advance the discipline of socio-hydrology.

Reliable water sources are central to human and environmental health. In south Texas, USA, the Nueces River Basin (NRB) directly or indirectly plays that important role for many counties. Several NRB stream segments are designated as ecologically significant because they serve crucial hydrologic, ecologic, and biologic functions. The hydrologically significant streams recharge the Edwards Aquifer, an essential water source for the region’s agricultural, industrial, and residential activities. Unfortunately, the semiarid to arid south Texas climate leads to large inter-annual precipitation variability which impacts streamflow, and as a consequence, the aquifer’s recharge. In this study, we used a suite of hydrologic metrics to evaluate the NRB’s hydroclimatic trends and assess their potential impacts on the watershed’s ecologically significant stream segments using precipitation and streamflow data from the National Climatic Data Center (NCDC) and Hydroclimatic Data Network (HCDN) respectively from 1970 to 2014. The results consistently showed statistically significant decreasing streamflow for certain low-flow indicators over various temporal scales, likely due to water rights diversions and minimal land use changes. This research could help decision-makers develop the necessary tools to manage water resources in south Texas, given the NRB’s significance as a source of water for domestic consumption and ecological health.

An intensive review of existing Water Law has just been conducted by the Department of Water Affairs and Forestry. The review was motivated by the need for preparation for new legislation to support water resource management with a goal of “some for all, forever.” The development of a water resource protection policy was begun in that review. This paper describes the major aspects of the policy at one point in a process of rapid development. Initial proposals are to use the concept of ecological integrity as an indicator of sustainable use of the resource. While management's goal is to ensure all water users will benefit from access to the water resource, ecological integrity provides a good indication of sustainability in the use of the resource. More discussion in this paper is, therefore, centred on ecological integrity than on individual water users under the assumption that the resource will only be able to provide for long term water uses if ecological integrity is assured. A water Reserve has been defined that is intended to protect water resources, so basic human needs can be met and ecological functions and processes can be sustained. Components of ecological integrity, that is, the chemical and physical characteristics of water, the quantity and assurance of water, the habitat (instream and riparian), and the structure and function of the associated biotic communities would be assessed through the use of a resource classification system. The approach integrates resource-directed measures for protection (such as resource quality objectives) with source-directed measures (such as effluent standards).

Environment plays a very significant role in human civilization. Human beings have close relations with the biosphere in which they live. The whole environment and ecology consisting of earth, air, water, plants and animals provide the necessary and sufficient conditions for sustaining human life. The last few centuries have been dominated by human beings, and are referred to by some scholars as ‘anthropocene’, or a period of human domination over the planet. This domination has impacted the planet, leading to the rapid depletion of wildlife and their habitat. In the last few decades, growing human populations and their consumption levels, accompanied by greater need for water, electricity, metal, food, housing and other luxury items has led to the quick erosion of other species. This loss of species has been guesstimated by various scholars at anywhere between one per hour to one per day. Although human beings are considered the most intelligent life form on earth, they are responsible for most of the damage done to planet earth. Developing countries as well as developed countries alike are all suffering from environmental pollution. Therefore, today environmental problems have been the object of discussion everywhere from village to parliament.

The water quality of most rivers near the settlements is below the optimal level, taking in account natural ecosystems condition and numerous needs of various users. Considering the environmental, economic and social importance of this factor, measures are required to improve natural reservoirs water quality management conducted by local civil autonomy and various levels of government. The goal of this work is to offer methodical recommendations on the system design of collecting, analyzing and forming the river’s water and ecosystems conditions database for the information support of complex management decision-making directed to accomplishment and preservation of the water bodies specified functional characteristics. Presently none of the existing methods of water environment assessment can take into account all possible biological communities’ responses to the various stress factors and their combinations impacts. For every type of impact the corresponding to it approaches in sampling and analysis methods are used; values of such methods are often difficult to collate and, especially, provide statistical evaluation of the water streams processes. The presented methods are based on the multimetric index application, which include parameters, reflecting biological communities biodiversity and stability in mountain type rivers, tolerance degree of the constituted them water organisms to external impacts and water environment toxicity for its inhabitants. Modern quality management, including quality of the processes, has a wide range of proven tools. The offered quality management process improvement method of the natural watersheds experiencing an anthropogenic pressure, is aiming to reach stability and guaranteed quality of the natural waters, based on the DMAIC quality management methodology and statistic quantitative methods united under the Six-Sigma approach. This article is the first in publications series devoted to the description of the methodology of the rivers ecological state monitoring and management using integrated biomarkers and quality management methods. Formed during the study organizational and methodical approaches can be applied to digital transformation of effective administrative decisions making process in sphere of water objects protection and development of the river’s catchment territory ecological planning within the project of the RF Construction Ministry “The Smart City”.

The European Water Framework Directive is the basis of sustainable water resources management in the European Union. The required “good status” of waterbodies can be achieved only by encouraging the application of natural renewable‐energy‐driven ecological engineering. Ecotechnological methods in wastewater treatment (e.g. constructed wetlands) can remove more than 90 per cent of total N and P, and organic load. These methods also save up to 80 per cent of the cost and energy compared with central technical systems. Because ecomorphology in around 80 per cent of German streams and rivers is disturbed to a high degree, increased efforts for renaturalization are necessary. Successful control concerning first initiated measures shows that improvement of stream morphology has a remarkable positive influence on water ecology.

Small- and medium-sized rivers are facing a serious degradation of ecological function in water resource-scarce regions of Northern China. Reservoir ecological operation can restore the damaged river ecological environment. Research on reservoir ecological operation and watershed management of urban rivers is limited in cold regions of middle and high latitudes. In this paper, the urban section of the Yitong River was selected as the research object in Changchun, Northern China. The total ecological water demand and reservoir operation water (79.35 × 106 m3 and 15.52 × 106 m3, respectively) were calculated by the ecological water demand method, and a reservoir operation scheme was established to restore the ecological function of the urban section of the river. To examine the scientific basis and rationality of the operation scheme, the water quality of the river and physical habitat after carrying out the scheme were simulated by the MIKE 11 one-dimensional hydrodynamic-water quality model and the Physical Habitat Simulation Model (PHABSIM). The results indicate that the implementation of the operation scheme can improve the ecological environment of the urban section of the Yitong River. A reform scheme was proposed for the management of the Yitong River Basin based on the problems in the process of carrying out the operation schemes, including clarifying department responsibility, improving laws and regulations, strengthening service management, and enhancing public participation.

To protect the river ecosystem and sustain ecological flow regime, it’s vital to consider environmental flow management in reservoir operation. Many researches try to use more detailed environmental flow management strategies to improve ecological flow regime. However, ecological flow regime not only is influenced by environmental flow management strategy, but also by three kinds of parameters, including reservoir capacity, reservoir inflow and water supply yield. The aim of this paper is to illustrate how ecological flow regime is affected by different reservoir capacities, reservoir inflows and water supply yields and to find a proper reservoir capacity, reservoir inflow or water supply yield under which the optimal ecological flow regime is the best and could not be improved. In this paper, an environmental flow management strategy, which is Four-period release approach (FP), is developed. Besides, social benefit and ecosystem needs are satisfied simultaneously. The results show that changing reservoir capacity, reservoir inflow or water supply yield could improve ecological flow regime.

The modern problems of irrigation sector and need of its reforms are presented as well as the importance of evaluation of reforms results via system of indicators that characterized efficiency of water use and effectiveness of water management. For this purpose, the methods of system analysis are used and the main economic and ecological factors influencing the efficiency of water use are determined. Based on the results of the system analysis an indicative assessment proposed for the following three spatial levels: for assessment of the efficiency of the irrigation sector at the national level; evaluation of water management efficiency at the level of main infrastructure and; at the level of non-state irrigation network. The efficiency of water use in irrigated agriculture at the national level is calculated as the added value in agriculture sector related to the amount of water taken for agricultural purpose. This indicator shows general productivity of water use in irrigated agriculture. Groups of ecological and economic indicators that proposed for assessing the efficiency of water use on the level of the main irrigation infrastructure allow to assess the quality of irrigation service under existing management model. For evaluation of efficiency of water use and management at the level of water users’ organizations and individual farms the following economic indicators are selected: land productivity; water productivity; irrigation area; volume of water used for irrigation; costs of irrigation and amount of production. The soil fertility and ecological state of the irrigated lands proposed as a main ecological indicator. In addition to the economic and ecological indicators the number of organizational and technological factors that provides reliability of water supply to the fields and show a effectiveness of water management should be evaluated also. The proposed integrated system of indicators can be used to evaluate the state of water use and water management in irrigated agriculture, as well as to assess the results of institutional reforms of the sector that approved by the state strategic documents.

Abstract. Rebalancing water allocation between human consumptive uses and the environment in water catchments is a global challenge. This paper proposes a socio-hydrological water balance framework by partitioning catchment total evapotranspiration (ET) into ET for society and ET for natural ecological systems, and establishing the linkage between the changes of water balance and its social drivers and resulting environmental consequences in the Murray–Darling Basin (MDB), Australia, over the period 1900–2010. The results show that the 100-year period of water management in the MDB could be divided into four periods corresponding to major changes in basin management within the socio-hydrological water balance framework: period 1 (1900–1956) – expansion of water and land use for the societal system, period 2 (1956–1978) – maximization of water and land use for the societal system, period 3 (1978–2002) – maximization of water use for the societal system from water diversion, and period 4 (2002–present) – rebalancing of water and land use between the societal and ecological systems. Most of management changes in the MDB were passive and responsive. A precautionary approach to water allocation between the societal and ecological systems should be developed. The socio-hydrological water balance framework could serve as a theoretical foundation for water allocation to evaluate the dynamic balance between the societal and ecological systems in catchments.

Abstract Adaptive management is currently an important method to optimize the management of complex water resources systems. Regional water resources adaptive management was conducted based on the advanced theory of a complex system multi-agent model; the state of an agent was tracked and modified by information entropy theory, which was improved by using individual standard deviations. With the goal of optimizing the adaptation of each agent of the region, water resources in the major grain production area of China were managed under the constraints of the total annual available water resources and water use efficiency requirements for 2015 and 2030. By introducing the adaptive water resources management in 2015, the domestic benefits and economic benefits increased by 2.90% and 14.81%, respectively, with respect to observed values. The ecological benefits declined by 3.63%, but ecological water demand was fully satisfied, and the ecological water environment was improved. Given the water use efficiency targets in 2030, applying adaptive management resulted in an increase of domestic, economic, and ecological benefits of 34.29%, 21.14%, and 1.78%, respectively. The results show that the adaptive management method presented can help managers to balance the benefits of various agents to determine the direction of water resources management decisions.

Danjiangkou Reservoir and its upstream tributaries as water resource area is of strategic importance for the Mid-route of South-to-North Water Transfer Project. Ecological and water security are the key measures for sustainable water diversion. Green water management as a new technology to achieve water conservation and water purification has a broad application prospects. In this research, green water management such as bench terraces, contour tillage, mulching and stone line was studied in the Upper Du watershed. ArcSWAT model was used to assess effect of green water management on river base flow. The results show that four green water management measures activated the regulating action of “soil water reservoir”. Base flow in export section of Upper Du river basin is increased under different four green water management measures, and especially the base flow increased more obvious in non-flood season. That is helpful to improve the ecological security degree in water resources area.

No other environmental variable of ecological importance to estuarine and coastal marine ecosystems around the world has changed so drastically, in such a short period of time, as dissolved oxygen. Coastal surveys in United States and Europe found that a staggering 78 % of the assessed continental U.S. coastal area and approximately 65 % of Europe’s Atlantic coast exhibit symptoms of eutrophication. The 65 % of the coasts counted by Diaz does not take into account inland seas like the Adriatic or Baltic Seas but also for these, eutrophication and consequently anoxia are common problems. In the present study a simple and economic device is proposed to enhance vertical mixing processes and to induce aeration of deep water by pumping of oxygen-rich surface water downwards to a desired depth around the halocline. The hydrodynamic parameters of the device are estimated through free oscillation tests. Preliminary values of the downward water flux velocity inside the device and the movements of the floater under the action of 4 regular waves, characterizing of the wave climate in the Nord Adriatic Sea, are estimated.

Abstract The need for guidance on the bioassessment and management of contaminated sediment has been articulated by Remedial Action Plan practitioners, the International Joint Commission, scientists, and managers in many jurisdictions. Encouragingly, a convergence of opinion, on what constitutes a comprehensive sediment assessment, is beginning. However, there continues to be a need for methods to interpret and integrate multiple pieces of information on sediment chemistry, biological information from field monitoring and laboratory sediment bioassessment in an ecologically meaningful way. This paper recommends an approach to comprehensive sediment bioassessment that is driven by the need to rehabilitate “beneficial uses” as described in the Great Lakes Water Quality Agreement. The paper also highlights advances in data interpretation that are facilitating he development of sediment management strategies.
