Babiker, Insaf; Mohamed, Mohamed; Hiyama, Tetsuya - In: Water Resources Management 21 (2007) 4, pp. 699-715

Assessing the quality of groundwater is important to ensure sustainable safe use of these resources. However, describing the overall water quality condition is difficult due to the spatial variability of multiple contaminants and the wide range of indicators (chemical, physical and biological)...

Water quality management of a stretch of river Yamuna: An interactive fuzzy multi-objective approach

Singh, Ajit; Ghosh, S.; Sharma, Pankaj - In: Water Resources Management 21 (2007) 2, pp. 515-532

This paper presents an Interactive Fuzzy Multi-Objective Linear Programming (IFMOLP) model for water quality management in a river basin. The IFMOLP model formulated will first evaluate dissolved oxygen (DO) concentrations or DO deficits at a point in different reaches depending on the overall...

Critical Flow for Water Management in a Shallow Tidal River Based on Estuarine Residence Time

Huang, Wenrui; Liu, Xiaohai; Chen, Xinjian; Flannery, … - In: Water Resources Management 25 (2011) 10, pp. 2367-2385

To support the development of protective water resources management strategies, a 3D hydrodynamic model was applied to the Little Manatee River (LMR) to evaluate the effects of reducing river flow and drought on the Estuarine Residence Time (ERT). ERT is an important indicator for estuarine...

Evaluation of rainfall erosivity and its temporal variation in the Yanhe River catchment of the Chinese Loess Plateau

Yue, B.; Shi, Z.; Fang, N. - In: Natural Hazards 74 (2014) 2, pp. 585-602

The potential of rain to generate soil erosion is known as the rainfall erosivity (R), and its estimation is fundamental for a better understanding of the erosive ability of certain rainfall events. In this paper, we investigated the temporal variations of rainfall erosivity using common daily...

Critical Environmental Flows to Support Integrated Ecological Objectives for the Yellow River Estuary, China

Sun, T.; Yang, Z.; Cui, B. - In: Water Resources Management 22 (2008) 8, pp. 973-989

The volume of inflowing water needed to meet multiple demands in the Yellow River Estuary of China was examined and quantified. Pressure on available environmental flows comes from varied ecological objectives, including maintenance of freshwater habitat for hundreds of plant and animal species,...

Refill and Drawdown Rules for Parallel Reservoirs: Quantity and Quality

Paredes, Javier; Lund, Jay - In: Water Resources Management 20 (2006) 3, pp. 359-376

This paper presents two operating rules for the refill and drawdown seasons of reservoirs in parallel for water supply, considering water quality. For the refill season a Linear Programming form of the New York City Rule is developed. Another Linear Programming form based on equalizing the...

Hydrodynamic Model of the Lower Hudson River Estuarine System and its Application for Water Quality Management

Novikov, Andrei; Bagtzoglou, Amvrossios - In: Water Resources Management 20 (2006) 2, pp. 257-276

In this paper a hydrodynamic model and associated post-processing tools for the Lower Hudson River (LHR) are presented. The model computes the two-dimensional (2D), depth-averaged Eulerian time-dependent velocity field in response to various external signals. The paper documents the mathematical...

An Inexact Chance-constrained Quadratic Programming Model for Stream Water Quality Management

Qin, X.; Huang, G. - In: Water Resources Management 23 (2009) 4, pp. 661-695

in formulating and solving the resulting inexact nonlinear optimization problems. In this study, an inexact chance …-point-source waste reduction (MWR) optimization model as water-quality constraints. The interval quadratic polynomials were employed to …. The results demonstrated that the proposed optimization model could effectively communicate uncertainties into the …

Product Policy as an Instrument for Water Quality Management

Ast, J. Van; Blansch, K.; Boons, F.; Slingerland, S. - In: Water Resources Management 19 (2005) 2, pp. 187-198

A main reason for the persistence of current water pollution lies in the diffuse character of many of its sources. For a large part such diffuse pollution is related to the production, use and waste of various kinds of products. For the reduction of this pollution, a product-oriented policy...
