This paper presents an approach to examine potential relationships between land use-derived solutes and baseflow surface water quality using regional ground water and solute transport models linked to GIS. We demonstrate this approach by estimating the chloride fluxes from road salt through ground water into surface water in a regional coastal watershed in Michigan. The geologically parameteriz...

Lack of sewage collection systems, percolation of surface waters, and seepage of wells have raised the groundwater table in Shiraz area in the south of Iran. The growing population generates environmental pollution resulting in the degradation of the quality of surface and groundwaters used for agriculture. Inorganic and organic pollutants have been traced in Shiraz water resources. Heavy metal...

Abstract Water scarcity threatens people in various regions, and has predominantly been studied from a water quantity perspective only. Here we show that global is driven by both quality issues, quantify expansions clean technologies (i.e. desalination treated wastewater reuse) to ‘reduce the number of suffering scarcity’ as urgently required UN’s Sustainable Development Goal 6. Including tempe...

The ecological assessment of the quality surface water Dnipro basin (within Zhytomyr region) is carried out. In general, rivers teter, rotten, Guiva, forest stone, Irsha, Human, Arpin, Rostavitsa and Kamyanka were investigated. study was conducted according to systematic observations based on classification estuates in Ukraine, which includes a set hydrophysical, hydrochemical, hydrobiological ...

Background & Aims of the Study: Water resources are useful or potentially useful. Uses of water are included agricultural, industrial, household, recreational and environmental activities. The majority of human uses require fresh water. Rivers are parts of this fresh water that play a very important role in the water cycle, acting as drainage channels for surface water. Hence, ...

treated sea water is the most significant source of water and surfactant floods. the various chemicals employed in treatment plants should be compatible with surfactant systems. based on surface tension experiments, the activity of these chemicals is examined over a wide range of concentrations in different solutions, including distillated water, sea water by using three types of surfactant mix...

surface-piercing propellers (spps) have been widely used in high speed craft due to some desirable features such as high efficiency, omission of resistance of equipment attached to the propeller and proper functioning of cavitation. unlike the submerged propellers, theoretical methods have no significant application on simulation of sppsbecause of problems related to modeling of these propeller...
