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 ...

The impact of industrial effluent on the Oruku River in southwestern region of Nigeria was investigated. Surface water, sediment, ground water and industrial effluent samples were obtained bimonthly for 18 months (March 2005 to September 2006). Effluent characteristics varied widely with averages of DO (4.25±1.3 mg/L), BOD (27.5±43 mg/L), Pb (0.41±0.26 mg/L), Cr (0.26±0.48 mg/L) and Ni (0.19±0....

In this paper, the utility of Landsat TM imagery for water quality studies in East Texas is investigated. Remote sensing has an important and effective role in water quality management. Remote sensing satellites measure the amount of solar radiation reflected by surface water and the reflectance of water depend upon the concentration and character of water quality parameters. Three water qualit...

abstract statement of the problem: surface roughness is a key factor in the aesthetics of restorative dentistry as it can determine the clinical quality and success of restorative materials. the chemical process of dissolution in the presence of mechanical forces can accelerate the surface roughness of tooth-coloured restorative materials. objectives: to determine the degree of surface roughnes...

The Danube is an international river passing partly through Serbia. The protection of the environment and sustainable use of water resources is a primary task that implies constant monitoring of the quality status and evaluation of ecochemical status of the water in the Danube basin. The investigation includes calculation of all-inclusive water quality by the Serbian water quality index (SWQI) ...

water samples have been collected from key parts of haraz river along different points andanalyzed for various water quality parameters during winter and spring season. effects of industrial wastes,municipal sewage, fish farming and agricultural runoff on river water quality have been investigated. thesurvey was conducted on along the haraz river (185 km) from near its headwaters at the polour,...
