Satellite data have been used for temperature modeling both in urban areas and water. This paperstudies viability of ASTER satellite images that provide high spatial and spectral resolution to model watersurface temperature, as a fundamental water quality parameter. This study is focused on Dez dam reservoirresiding in Khuzestan province, south west of Iran. After the image corrections required...

background: nitrate and nitrite compounds are considered as groundwater’s contamination factors, which in recent years, their densities have been growing in these resources. this study was conducted aiming to measure nitrate and nitrite density in drinking water wells in villages around the industrial estate, city of orumieh, and to compare them to the approved standards. methods: this was a de...

Ground-water flow modeling is an important tool frequently used in studies of ground-water systems. Reviewers and users of these studies have a need to evaluate the accuracy or reasonableness of the ground-water flow model. This report provides some guidelines and discussion on how to evaluate complex ground-water flow models used in the investigation of ground-water systems. A consistent threa...

Main perennial rivers of Gujarat, Tapi, Narmada, Mahi and Sabarmatiare meeting Arabian Sea in Gulf of Khambhat. The out flow of Mahi River intothe sea is decreased due to construction of dams like Bajaj Sagar, Kadana, Panamand Wanakbori weir. So, Tidal effect of sea and sea water intrusion is beingincreased on landward side. Moreover, due to erratic nature of rainfall andimproper management of ...

it is over two decades that groundwater flow models are routinely implemented for better management of groundwater resources.modeling groundwater flow with the help of the ground water modeling system (gms) in the damghan plain aquifer in northern iran,which experiences declining levels and numerous environmental hazards, has demonstrated that, (a) in the worst case scenario theaquifer will fac...

Ground water flow was investigated at Clear Lake, a 1468-ha glacial lake in north-central Iowa, as part of a comprehensive water quality study. A multiscale approach, consisting of seepage meters (and a potentiomanometer), Darcy's law, and an analytic element (AE) model, was used to estimate ground water inflow to and outflow from the lake. Estimates from the three methods disagreed. Seepage me...

background: in the present times, arsenic poisoning contamination in the ground water has caused lots of health‑related problems in the village population residing in middle gangetic plain. in bihar, about 16 districts have been reported to be affected with arsenic poisoning. for the ground water and health assessment, simri village of buxar district was undertaken which is a flood plain region...

GSFLOW is a new U.S. Geological Survey model for simulating ground-water/surface-water interactions. GSFLOW couples PRMS (the Precipitation Runoff Modeling System) to MODFLOW (the Modular Ground-Water Model) with modules for simulating flow and storage in unsaturated-zones, lakes, and streams. GSFLOW simulates infiltration, runoff generation, and lateral flow in temporarily saturated material (...
