introduction the special regional and geographical characteristics of iran, the flowof streams with mediterranean regime, topographic status, and diversity of relieves have provided an extensive areafor the penetration of water into the ground. all of these factors together with the shortage of ground water reservoirs have enhanced the significance of ground water in iran. since the volume of g...

This case study was carried out to determine the ground water quality of Madurai district, Tamilnadu, India. The results of various samples of water collected from the observation wells/bores at the seven Taluks of the Madurai district during the period of 2001-2011at periodical intervals by the Ground Water Wing of Public Works Department of Tamil Nadu have been collected by the present author...

Two forms of water service delivery in peri-urban settlements in the eThekwini municipal region are communal stand-pipes and household ground-tanks. Water from these sources requires storage prior to use. Previous studies have shown that water quality tends to deteriorate during storage. This study was conducted during the winter season and tested water from standpipe and ground-tank households...

Contamination of ground water is a major concern for citizens as well as local, state, and federal agencies that are involved with the management, quality and quantity of water and human health. However, the generation of vulnerability maps or delineations of vulnerable zones in a map for monitoring purposes are difficult since ground water contamination depends upon numerous, complex interacti...

Information based agriculture (IBA) includes matching of agronomic practices with soil and water characteristics and their spatial variability for enhancing productivity. An attempt was made to derive agriculture management zones based on soil and water characteristics for sustainable agricultural production in Mansa district (Punjab, India). Based on physiographic analysis and semi detailed so...

Anaerobic microbial processes play particularly important roles in the biogeochemical functions of wetlands, affecting water quality, nutrient transport, and greenhouse gas fluxes. This study simultaneously examined nitrate and sulfate removal rates in sediments of five southwestern Michigan wetlands varying in their predominant water sources from ground water to precipitation. Rates were estim...

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...
