Abstract The problem of noise pollution in Baghdad, the capital city Iraq, is getting worse every day as a result increased volume traffic. This presents considerable risk, particularly on main roads that connect densely populated neighborhoods such Al-Sadr City district with central capital. In order to inform decision-makers urban development and environmental policy about high values require...

Introduction: The present study aimed to compare the performance of two widely-used models for spatial assessment of particulate matter less than 10 microns (PM10) in ambient air of Yazd city. Finally, effective factors on concentrations of pollutants and corresponding standards were investigated. Materials and Methods: A number of 13 sampling stations were employed in different areas of Yazd ...

Several areas in Semarang City have been unable to get a clean water supply through the Local Water Company (PDAM) channel. One of solutions that can be done overcome this problem is by utilizing groundwater, which obtained building deep well made obtain rock layers accommodate and drain groundwater (aquifer layer). To find out approximate depth aquifer layer, it necessary conduct preliminary i...

drought monitoring is a fundamental component of drought risk management. it is normally performed using various drought indices that are effectively continuous functions of rainfall and other hydrometeorological variables. in many instances, drought indices are used for monitoring purposes. geostatistical methods allow the interpolation of spatially referenced data and the prediction of values...

Groundwater depletion has become a major concern all over the world. Recently, rapid population growth and need for water food have placed massive strain on land resources. In this study, groundwater resulting from land-use climate change was investigated in Faisalabad district, Pakistan, 2000 to 2015. A Pearson correlation analysis between climatic parameters indices with conducted explore inf...

Groundwater quality management is one of the most important issues in many arid and semi-arid regions, including Iran.Nitrate (NO3-) is one of the most common anions contaminating groundwater. This study aimed to range nitrateconcentrations in water resources in Bahabad plain in Yazd province. To evaluate the nitrate data in this descriptive study,260 nitrate samples from 13 wells in Bahabad we...

A watershed management program is usually based on the results of watershed modeling. Accurate modeling results are decided by the appropriate parameters and input data. Precipitation is the most important input for watershed modeling. Precipitation characteristics usually exhibit significant spatial variation, even within small watersheds. Therefore, properly describing the spatial variation o...

Previous studies have shown that the presence of nitrate in drinking water can cause several diseases especially in the infants, such as cancer and blue baby. The Environmental Protection Agency (EPA) has since adopted the 50 mg/l standard as the maximum contaminant level (MCL) for nitrate for regulated public water systems. This study aimed to evaluate the concentration of nitrate in the drink...

In this paper, a hybrid inverse distance weighted (IDW) and the imperialist competitive algorithm (ICA) was proposed for grade estimations in mining projects. Indeed, coefficients of IDW equation, power, influence were modified by applying ICA algorithm. For this, an example solved using IDW, ordinary kriging, IDW-ICA. After successfully validating IDW-ICA, iron grades estimated Baba Ali mine, ...
