  • Dynamic simulation of water resource management focused on water allocation and water reclamation in Chinese mining cities

    Mining cities have undergone the process of extensive exploitation, which always results in a series of water issues. Integrated water resource management is necessary in improving water supply, allocation and quality without damaging economic development. This article constructs a linear optimization model including a ‘Top-Down’ socio-economic mode, and ‘Bottom-Up’ water quality control and ...

  • 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 large-scale conjunctive management model of water resources for an arid irrigation district in China

    The quantity of available water resources has been recognized as the key limiting factor for development of most of the arid regions. This paper focuses on the simulation–optimization for conjunctive use of surface water and groundwater on a large scale. In this study, Hetao Irrigation District in China, one of the largest irrigation districts in the Yellow River basin, is selected as a ...

  • 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 ...

  • 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 ...

  • Simulation study of the sustainable utilization of urban water resources based on system dynamics: a case study of Jiamusi

    To achieve sustainable utilization of urban water resources and sustainable social and economic development and to relieve the supply–demand pressure related to water resources in Jiamusi, a simulation model based on system dynamics theory is established to identify the feedback mechanism and the causal relationship among the factors affecting the sustainable utilization of water resources. ...

  • A web-based environmental decision support system for legacy models

    An environmental decision support system (EDSS) was designed for the Occoquan system in Northern Virginia, USA. This EDSS is available through the internet using web-browsers, and enables stakeholders to interact with complexly-linked water resources models for the Occoquan system based on seven implementations of HSPF and two implementations of CE-QUAL-W2 software. Using the web-interface of ...

  • Comparison of General Circulation Models: methodology for selecting the best GCM in Kermanshah Synoptic Station, Iran

    General Circulation Models (GCMs) suggest that rising concentrations of greenhouse gases will have significant implications for climate at global and regional scales. Increased concentration of greenhouse gases in the atmosphere leads to change in air temperature and precipitation. Temperature and precipitation are important parameters for water management, so the climate change studies on ...

  • Forecast-based analysis for regional water supply and demand relationship by hybrid Markov chain models: a case study of Urumqi, China

    A clear understanding of regional water supply and demand trend is crucial for proper water resources planning and management in water-deficient areas, especially for Northwest China. In this study, three hybrid stochastic models (Markov chain model, unbiased Grey-Markov model and Markov model based on quadratic programming) were developed separately for predicating the available water ...

  • 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 ...

  • Climate change impact assessment on water resources in Iran: applying dynamic and statistical downscaling methods

    As a result of inappropriate management and rising levels of societal demand, in arid and semi-arid regions water resources are becoming increasingly stressed. Therefore, well-established insight into the effects of climate change on water resource components can be considered to be an essential strategy to reduce these effects. In this paper, Iran's climate change and variability, and the ...

  • Water quality management in the context of future climate and development changes: a South African case study

    Globally, water resources are being over-utilised; a situation exacerbated by degenerating water quality of rivers. To achieve sustainable management of water resources, uncertainty under climate change and development must be considered. A companion study was the first to incorporate uncertainty within water resources development scenario modelling for a catchment in South Africa using the ...

  • An inexact multi-objective programming model for water resources management in industrial parks of Binhai New Area, China

    In recent years, Binhai New Area of Tianjin has been suffering severe water shortage due to climate change and industrial activities. Integrated and effective water resources management approaches are urgent for the sustainable development of industrial parks in Binhai New Area. However, uncertainties exist in many aspects of the water resources system and are inevitably problematic for water ...

  • Get more out of Water Resources Engineering Models

    The effort required to develop water resources engineering models can be significant. But once developed, in many instances the models are only evaluated for a limited, or a single set of conditions. The results and predictions obtained from these evaluations are the ones used in design, presented in reports and conveyed to decision makers and the public. This approach might serve ...

  • Water, energy, and food nexus: review of global implementation and simulation model development

    Water, energy, and food (WEF) have complex interconnections. Water is required to produce energy, while energy is needed for water extraction, treatment, and distribution. The food sector requires water and energy to produce food products, while fertilizer and pesticide from farmland have a negative impact on water quality; however, biomass is a potential alternative energy source. ...

  • 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 ...
