Background: Although experiments on water quality are time consuming and expensive, models are often employed as supplement to simulate water quality. Artificial neural network (ANN) is an efficient tool in hydrologic studies, yet it cannot predetermine its results in the forms of maps and geo-referenced data. Methods: In this study, ANN was applied to simulate groundwater quality ...

In 49 samples of groundwater, sampled in Muzaffargarh District of south-western Punjab, central Pakistan, concentrations of As exceeded the World Health Organisation provisional guideline value, and United States Environmental Protection Agency (USEPA) Maximum Contaminant Level (MCL), of 10 lg L 1 in 58% of samples and reached up to 906 lg L . In this semi-arid region canal irrigation has lead ...

Riparian forest buffers can improve stream water quality, provided they intercept and remove contaminants from surface runoff and/or shallow groundwater. Soils, topography, hydrology, and surficial geology detemine the capability of forest buffers to intercept and treat these flows. This paper describes landscape analysis techniques for identifying and mapping locations where forest buffers can...

Groundwater pollution by nitrates from agricultural sources is a common environmental issue. In order to support risk analysis, hazard maps are used classify land uses according their potential of pollution. The aim this study propose new index based on nitrogen input and its connection with nitrate concentration in groundwater. effectiveness the Nitrogen Input Hazard Index was tested Gallocant...

Abstract Groundwater is the main source of water supply in Sleman Regency. Although quantity not an issue, quality groundwater should be understood to ensure sustainability supply. A previous study shows increase manganese (Mn) and nitrate (NO 3 ) concentration groundwater, yet distribution unknown. Therefore, this aims develop a map spatial pattern analyze potential Regency Yogyakarta Province...

A Precious natural asset and prime resource for the basic need a human is water. Groundwater which commonly available as freshwater sources beneath earth's surface widely used in many parts of world domestic agricultural activities. In this present work, groundwater potential zone identification done by using remote sensing GIS. The thematic maps like soil, rainfall, drainage, DEM land use cove...

in this study, a method for determining the location and extent of myocardial infarction using body surface potential map data that is obtained from physionet challenge 2007 database has been suggested. this data is related to four patients with myocardial infarction that we used from two patients as training set to determine rules, and from two other patients for testing set and the conclusion...

A new method to study 3D saline front advancement in coastal fractured aquifers has been presented. Field groundwater salinity was measured in boreholes of the Bari (Southern Italy) coastal aquifer with depth below water table. Then, the Ghyben-Herzberg freshwater/saltwater (50%) sharp interface and saline front position were determined by model simulations of the freshwater flow in groundwater...
