The world is facing severe and growing challenges in maintainig water quality and meeting the rapidly growing demand for water resources. In addition, water used for irrigation, the largest use of water in most developing countries, will likely have to be diverted increasingly to meet the needs of urban areas and industry whilst remaining a prime engine of agricultural growth. Finally, environmental and other in-stream water demands become more important as economies develop. The river basin has been acknowledged to be the appropriate unit of analysis to address these chanllenges facing water resources management: and modeling at this scale can provide essential information for policy makers in their decisions on allication of resources. This paper reviews the state of the art of modeling approaches to integrated water resources management at the river basin scale, with particular focus on the potential of coupled economic hydrologic models, and concludes with directions for future modeling exercises.

Based on the water footprint (WF) concept, this book reviews WF-based water stress evaluation methods at the city, provincial and river basin levels respectively. In addition, it explores the factors that influence regional water footprint in the spatial sequence via the extended STIRPAT model. Highlighting the utilization of WF accounting in sustainable water management, one of the book’s goals is to establish the optimization model of water allocation in various industrial sectors. Based on WF accounting, which thoroughly considers the water input for production, the relevant intermediate water inputs, and the water amount for wastewater discharge dilutions, the book provides a wealth of insights for scholars and practitioners with an interest in water resources and environmental management. In addition, it exhibits a scientific plan for regional water resource utilization and allocation, helping relieve regional water shortages.

Describes the use of a distributed hydrologic model to evaluate different data scenarios. The study attempted to answer questions such as; what will happen to the basin water resources if a) there is a change in climate; b) it is decided that more water must be retained in the river for environmental reasons; c) more water is extracted for urban and industrial use; d) the timing and accounts used for water are changed?

An increasing number of hydrological datasets from earth observations, hydrological models and seasonal forecasts have become available for water managers, consultants and the general public. These datasets are state-of-the-art products which are usually accessible online and may contribute to develop hydrological studies and support water resources management. However, the added value of these datasets has not been completely explored in decision-making processes. Research studies have assessed how well data can help in predicting climate, but there is a lack of knowledge on how well data can help in water allocation decisions. This work provides numerical tools, methods and results to evaluate the value of using hydrological datasets to support water allocation decisions at river basin and irrigation district scale. An integrated approach is used to predict climate, improve decisions and reduce negative impacts. Results show that investing in hydrological data with finer spatial and temporal resolution and longer periods of record improves water allocation decisions and reduces agricultural production loss in large irrigation schemes. Using river discharge data from hydrological models and global precipitation enhances irrigation area planning when little in-situ data is available. Moreover, using seasonal streamflow forecasts improves available water estimates resulting in better water allocation decisions. The framework was tested in Costa Rica, Colombia and Australia, but can be applied in any case study around the world.

"The goal of this study was to examine the consequences of surface-water allocation policies in the Yellow River basin. This goal was accomplished using a mathematical optimization model developed by the World Bank. The first objective was to assess the economic efficiencey of the upper limits on the use of river water for irrigation and other purposes as established by the Chinese government. These limits were determined to be overly restrictive for some regions, resulting in significant economic losses unless revised to reflect the optimal uses of water. The second objective was to examine the economic implications of the current 'first come, first serve' water allocation policy. Results from model simulations suggest that water should be reallocated from upstream regions to lower regions in the basin in order to maximize the value added from water use. ... "--leaf [1]
