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)...

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...

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...

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...

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,...

Sediment generated by interrill erosion is commonly assumed to be enriched in soil organic carbon (SOC) compared to the source soil. However, the reported SOC enrichment ratios (ER_SOC) vary widely. It is also noteworthy that most studies reported that the ER_SOC is greater than unity, while...

This paper aims to analyse the underlying factors of varied behaviour shown in the store set of purchase of households during a time period (temporal variation). In order to examine whether there are differences between households with and without shopping varied behaviour, a Bayesian Separate...

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...

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...

In order to deal with problems related to both water quality and quantity as well as to strengthen the sustainable and integrative management of the nation’s water resources, the Vietnamese Government has adopted a wide spectrum of laws and regulations. In recent years, more than 300 water...
