This study aims to modify the SINTACS and DRASTIC models with a land-use (LU) layer compares modified-DRASTIC, modified-SINTACS SI methods for groundwater vulnerability assessment (GVA) in southern Tehran aquifer, Iran. Single parameter sensitivity analysis (SPSA) served determine most significant parameters approaches, revise model weights from “theoretical” “effective.” The inherent implementation of LU may explain its better performance compared unenhanced versions models. Validation all...
The prediction of municipal solid waste generation ( MSWG ) plays an important role in a management system. However, achieving the anticipated accuracy with regard to nonhomogeneous nature and effect various out control factors on is quite challenging. In this article, support vector machine SVM ), one artificial intelligence techniques, hybrid wavelet transform (WT) WT ‐ are used predict weekly time series Tehran Mashhad cites during period January 2006–December 2011. To improve performance...
Wastewater treatment plants (WWTPs) have a significant role in urban systems’ serviceability. These infrastructures, especially coastal regions, are vulnerable to flooding. To minimize vulnerability, better understanding of flood risk must be realized. quantify the extent efforts for management, unified index is needed evaluating resiliency as key concept vulnerability. Here, framework developed evaluate WWTPs areas New York City. An analysis current vulnerability performed and new...
The main purpose of the present investigation was to develop a pollution index for agricultural soils. For this purpose, 58 soil samples were collected from lands in Hamedan Province (Iran). elemental contents As, Cd and Co crops measured by atomic absorption spectroscopy. spatial distribution studied metals prepared Kriging method. It is concluded that activities have led higher concentrations Co, As. Results chemical partitioning studies revealed considerable portions soils are derived...
Background: Wastewater treatment is a critical environmental challenge, and moving bed biofilm reactor (MBBR) technology an effective solution. The selection of appropriate media significantly impacts efficiency, particularly in terms organic matter nutrient removal. This study aims to optimize for MBBR systems improve wastewater treatment. Methods: Three types-K3, MB3, K5-were evaluated based on key properties such as specific surface area (SSA), porosity, buoyancy, economic feasibility....
A vital key to the development of a reservoir eutrophication management strategy is link watershed-nutrient model water quality. To develop cost-effective optimization model, coupled watershed-reservoir with an has been developed design control strategies in watershed planning time horizon. This methodology can help reduce phosphorus concentration standard level. In this study, weather data for next 10 years was generated using downscaled GCM simulate load SWAT model. Then optimal selection...
In recent years, a number of biological processes have been used for bioremediation TNT contaminated soils. The goal this research was to select the proper formulation compost materials based on mechanically sorted organic fraction municipal solid wastes (MSW) that can provide balance carbon and nitrogen best conditions promote activity in reach highest removal. Seven factors, including soil (%w/w), trace element solution (%v/w), chicken manure concentration (mg/Kg), microbial suspension...
Anaerobic digestion (AD) treatment of agricultural and animal waste can be considered as a means enabling environmental remediation. This research investigated two conditions anaerobic co‐digestion maize cow dung. was done by placing mixture dung together in floating drum digester that run at different dung/maize ratios 10:1 10:5. Batch were on bench‐scale AD, 5 L volume, developed to operate under mesophilic (36 ± 1 ° C). Results showed biogas methane yields from the ratio lower than...
Heavy metal concentrations and magnetic susceptibility of sediment samples were analyzed as indicators urban industrial contamination in Anzali wetland Gilan, Iran. The aim was to investigate the suitability properties measurements for indicating heavy pollution. concentration six metals (Ni, Cr, Cd, Zn, Fe, Pb) determined different depths four core within regions (Abkenar, Hendekhaleh, Shijan Siakeshim). Average cores higher than severe effect level (SEL) Ni, Cr Fe (77.26, 113.63 ppm 5.2%,...
