Evaluation of groundwater quality in urban area, using Geostatistical methods in drought and wet periods (Case study: Mashhad city)
In many urban areas, groundwater has been exploited neglecting to wet and dry periods owing to of surface water deficit. In this study, using the percent of normal rainfall index, 36 year (1971-2008) were studied and a drought event and a wet event were determined. The reason to choose two consecutive years is the effect of early wet period on groundwater quality. Physicochemical characteristic...
متن کاملMachine Learning Algorithm for Prediction of Heavy Metal Contamination in the Groundwater in the Arak Urban Area
This paper attempts to predict heavy metals (Pb, Zn and Cu) in the groundwater from Arak city, using support vector regression model(SVR) by taking major elements (HCO3, SO4) in the groundwater from Arak city. 150 data samples and several models were trained and tested using collected data to determine the optimum model in which each model involved two inputs and three outputs. This SVR model f...
متن کاملEvaluation of groundwater contamination in the Marand study area under urban wastewater reuse conditions in agriculture using GODS
The study area of Marand city is 45 ° 46 'east longitude and 38 ° 26' north latitude and is located in the northwest of East Azarbaijan province and 60 km northwest of Tabriz province. Unfortunately, in recent years, the development of countries, including Iran, has led to more exploitation and improper use of groundwater resources, which reduces these resources and does not control the amount ...
متن کاملNumerical Simulation of Groundwater Flow in a River Valley Basin in Jilin Urban Area, China
In order to evaluate the groundwater resources and aquifer system of the Jilin urban area (JUA), a groundwater numerical flow model was established by using the groundwater modeling system based on data from 190 boreholes. River stages were interpolated to control the groundwater flow field. The input parameters such as hydraulic conductivity and specific yield were based on data from 260 pumpi...
متن کاملGroundwater Engineering in an Environmentally Sensitive Urban Area: Assessment, Landuse Change/Infrastructure Impacts and Mitigation Measures
A rise in the shallow unconfined groundwater at a site in Australia is causing water logging of the underground facility in the affected area. Realizing this problem, a study was conducted to identify the source of water that is causing the rise and to develop an implementation and operation plan of the mitigation (dewatering system). Modelling was undertaken using MODFLOW-SURFACT code, within ...
