  • Water Resources Management and Modeling

    Hydrology is the science that deals with the processes governing the depletion and replenishment of water resources of the earth's land areas. The purpose of this book is to put together recent developments on hydrology and water resources engineering. First section covers surface water modeling and second section deals with groundwater modeling. The aim of this book is to focus attention on the ...

  • Integrated modeling on water resource management

    World is facing a water crisis and increasing in recent years. It is necessary to understand the water system from source to sink and about 10% of total annual runoff is being used. Agriculture is found largest direct user of water. Asia is consuming about 23%, highest percentage of available water resources. Various steps for efficient water resources management are discussed. Decision support ...


  • Determining Proper Cooling Tower Size

    To maximize water-based cooling tower benefits, the appropriate tower size must be selected, requiring the identification of several critical factors. Cooling towers are a relatively inexpensive and reliable way of expelling heat from a number of industrial processes, including nuclear & thermal power plants, petroleum refineries, petrochemical plants, food processing plants, as well as HVAC ...

  • Privatization of Water-Resource Development

    This paper analyzes the inefficiencies from market power and return-flow externalities in private construction of a water project. The model pays special attention to increasing groundwater pumping costs, project set-up costs, limited project capacity, and return flow to the aquifer. For a given capacity, the return-flow externality causes project owners to construct the project too late when the ...

  • A model for risk minimisation on water resource usage failure

    We present a framework for solving the strategic problem of assigning transboundary water resources to demand centres under uncertainty in the water exogenous inflow in the reservoirs and other segments of the basin system along the time horizon. The functional to maximise is the probability of satisfying different targets on the stored water and different demands over a set of scenarios. A ...

  • In the image of the market: the Chilean model of water resources management

    Chile's free-market Water Code turned 20 years old in October 2001. This anniversary was an important milestone for both Chilean and international debates about water policy, because Chile has become the world's leading example of the free-market approach to water law and economics and water resources management - the textbook case of treating water rights, not merely as private property, but ...

  • Integrating water resources management in eco-hydrological modelling

    In this paper the integration of water resources management with regard to reservoir management in an eco-hydrological model is described. The model was designed to simulate different reservoir management options, such as optimized hydropower production, irrigation intake from the reservoir or optimized provisioning downstream. The integrated model can be used to investigate the impacts of ...

  • A coupled model for water resources allocation regarding water quality control

    In this study, a fuzzy credibility constrained programming (FCCP) model is developed for water quantity and quality management with uncertainties in water quality parameters. The proposed method could reflect not only inexact uncertainties in the objective function, variables and parameters, but also fuzzy uncertainties in the right-hand side. Credibility levels which represent satisfaction ...

  • Drinking Water Resource Protection, Germany

    Reference Project: Drinking Water Resource Protection, Germany In the catchment area of a major drinking water supplier in western Germany increasing nitrate concentrations were noticed within a deep water-bearing layer. Although high nitrate concentrations, resulting from regional intensive application of fertilizers, were known from shallow layers in the area, they were new to the deep ...

  • Bi-level optimization allocation model of water resources for different water industries

    There are severe water shortages, exacerbated by overexploitation, in the region upstream of the dam at Zhang Jiakou, and in many other regions, both in China and other parts of the world. Allocating water resources equitably amongst the numerous domestic and industrial consumers in these regions, while preserving or improving the environment and meeting economic goals, is a highly complex ...

  • A study of multi-objective dynamic water resources allocation modeling of Huai River

    Water resources supply and demand has become a serious problem. Water resources allocation is usually a multi-objective problem, and has been of concern for many researchers. In the north of China, the lack of water resources in the Huai River Basin has handicapped the development of the economy, especially badly in the low-flow period. So it is necessary to study water resources allocation in ...

  • An optimization model for water resources allocation risk analysis under uncertainty

    In order to deal with the risk of low system stability and unbalanced allocation during water resources management under uncertainties, a risk-averse inexact two-stage stochastic programming model is developed for supporting regional water resources management. Methods of interval-parameter programming and conditional value-at-risk model are introduced into a two-stage stochastic programming ...

  • Sustainable use of water resources in Europe and the role of integrated modelling of phosphate fluxes

    Sustainable management of European water resources is advanced by the implementation of the Water Framework Directive. To achieve its aims the directive requires the realisation of cost-efficient programmes of measures. In this context, also measures for reducing phosphate inputs have to be taken, which demands models as quantification tools for the status quo analysis as well as for scenario ...

  • A simulation/optimization model for selecting infrastructure alternatives in complex water resource systems

    The paper introduces a simulation/optimization procedure for the assessment and the selection of infrastructure alternatives in a complex water resources system, i.e. in a multisource (reservoirs) multipurpose bulk water supply scheme. An infrastucture alternative is here a vector X of n decision variables describing the candidate expansions/new plants/water ...

  • The application of a drought reconstruction in water resource management

    This study uses extended (1880s–2012) rainfall series to examine the implications of historical droughts on water supply yield calculations used in water resource management and drought planning across the English Midlands and Central Wales. UK guidance to water companies is to use climate data from the 1920s to present where possible in modelling to inform water resource management and ...

  • An optimization procedure for the sustainable management of water resources

    The sustainable management of water resources requires the identification of procedures to optimize the use and management of resources that are able to deal adequately with the problems of an integrated water service. Taking cue from the classic problem of transport of operations research, this paper proposes a procedure to optimize the allocation of resources for water supply in an area. The ...

  • Dynamic simulation of water resources in an urban wetland based on coupled water quantity and water quality models

    Water quality in wetlands plays a huge role in maintaining the health of the wetland ecosystem. Water quality should be controlled by an appropriate water allocation policy for the protection of the wetlands. In this paper, models of rainfall/runoff, non-point source pollution load, water quantity/quality, and dynamic pollutant-carrying capacity were established to simulate the water ...

  • Interdependence in water resource development in the Ganges: an economic analysis

    It is often argued that the true benefits of water resource development in international river basins are undermined by a lack of consideration of interdependence in water resource planning. Yet it has not been adequately recognized in the water resources planning literature that overestimation of interdependence may also contribute to lack of progress in cooperation in many systems. This paper ...
