“…To capture hydrological dynamics, many integrated models of environmental flows have used single-dimensional linear network models with environmental flows occurring between interconnected nodes (e.g., Letcher et al 2007, George et al 2011a, b, Yin and Yang 2011. Without a spatial approach, linking hydrological flow rates with environmental flow metrics for specific areas of river ecosystem types is not possible and the ability of the model to capture key ecohydrological processes is limited.…”

Abstract. Investment in and operation of flow control infrastructure such as dams, weirs, and regulators can help increase both the health of regulated river ecosystems and the social values derived from them. This requires high-quality and high-resolution spatiotemporal ecohydrological and socioeconomic information. We developed such an information base for integrated environmental flow management in the River Murray in South Australia (SA). A hydrological model was used to identify spatiotemporal inundation dynamics. River ecosystems were classified and mapped as ecohydrological units. Ecological response models were developed to link three aspects of environmental flows (flood duration, timing, and interflood period) to the health responses of 16 ecological components at various life stages. Potential infrastructure investments (flow control regulators and irrigation pump relocation) were located by interpreting LiDAR elevation data, digital orthophotography, and wetland mapping information; and infrastructure costs were quantified using engineering cost models. Social values were quantified at a coarse scale as total economic value based on a national survey of willingness-to-pay for four key ecological assets; and at a local scale using mapped ecosystem service values. This information was integrated using a constrained, nonlinear, mixed-integer, compromise programming optimization model and solved using a stochastic Tabu search algorithm. We tested the model uncertainty and sensitivity using 390 Monte Carlo model runs at varying weights of ecological health vs. social values. Integrating ecohydrological and socioeconomic information identified environmental flow management regimes that efficiently achieved both ecological and social objectives. Using an ecologically weighted efficient and socially weighted efficient scenario, we illustrated model outputs including a suite of cost-effective infrastructure investments and an operational plan for new and existing flow control structures including dam releases, weir height manipulation, and regulator operation on a monthly time step. Both the investments and management regimes differed substantially between the two scenarios, suggesting that the choice of weightings on ecological and social objectives is important. This demonstrates the benefit of integrating highquality and high-resolution spatiotemporal ecohydrological and socioeconomic information for guiding the investment in and operational management of environmental flows.

“…The term "environmental flows" is now commonly used to refer to a flow regime designed to maintain a river in certain agreed ecological condition (George B., et al, 2011). The term should always be used in plural, implying that a synonym to environmental flows is an ecologically acceptable flow regime designed to maintain a river in an agreed or predetermined state (Smakhtin & Anputhas, 2006).…”

Article InformationThe sustainable development of water resources is a multi-dimensional way of thinking about the connections or interdependencies among natural, social, and economic systems in the use of water. The purpose of environmental impact assessment is to guarantee a sustainable development that is in harmony with human welfare and the conservation of ecosystems and hence it should be clearly understood by all concerned. The main purpose of this paper is to review the current level of understanding of environmental impact assessment of water resources development; to assess the major challenges to sustainable environmental systems from water resources development perspectives, and to identify major environmental issues that need to be considered in sustainable water resources planning and development. During project study and design, major environmental impacts of water resources development should be identified and made available for decision makers and the public. In the arena of Integrated Water Resources Management, the environment should be considered as one of the legitimate users of water, and allotted reasonable amount of water for its sustainability. Hence, environmental flows assessment should be a mandatory condition for granting permission for project construction. Besides, as catastrophic flood events resulting from dam breaches are enormous, performing dam breach flood wave propagation and inundation mapping during the design phase of the project would support timely decision on the fate of the project or identifying mitigating measures to be taken. In the instances of shortage of geographic data, remotely sensed data can be analysed in GIS environment to generate data and map the information. Simulation models, coupled to GIS, would add GIS layers to provide clarity of impacts. To bring about environmental integrity of water resources development, the major challenges like population pressure, climate change, lack of proper planning and integration, policies and institutional arrangements should be properly addressed.
