Measuring Impervious Surfaces for Non-point Source Pollution Modeling
The US EPA has reported non-point source pollution (NPS), which includes eroded sediments, toxic contaminants, nutrients, debris, and other pollutants, to be the number one threat to surface water quality nationwide. Numerous studies have established a direct relationship between the amount of impervious surface within a watershed and pollution of its surface waters. However, without detailed d...
متن کاملModeling of Non-Point Source Pollution by Long-Term Hydrologic Impact Assessment (L-THIA) (Case Study: Zayandehrood Watershed) in 2015
Background & Aims of the Study: In this research, Long-Term Hydrologic Impact Assessment model is selected for simulation of runoff and NPS pollution. The aim of this study is modeling of non-point source pollution by L-THIA model in Zayandehrood watershed in 2015. Materials & Methods: In this study, analytical survey and investigation of references in the context of libr...
متن کاملModelling of point and non-point source pollution of nitrate with SWAT in the river Dill, Germany
We used the Soil and Water Assessment Tool (SWAT) to simulate point and non-point source pollution of nitrate in a mesoscale mountainous catchment. The results show that the model efficiency for daily discharge is 0.81 for the calibration period (November 1990 to December 1993) and 0.56 for the validation period (April 2000 to January 2003). The model efficiency for monthly nitrate load is 0.66...
متن کاملContracting for Non - Point - Source Pollution Abatement
This paper presents an incentive scheme to control agricultural non-point-source pollution. The analysis is based on a nested agent framework with three parties; farmers, a country’s government, and the governments of all countries that affect each other’s environmental quality. Unlike previous analysis of incentive schemes to control agricultural pollution, we suggest non-individual contracts ...
متن کاملnon point source pollution modeling and critical area priority for environmental management of tajan watershed
non-point pollution are an important factor in determining water quality and eutrophication of fresh water. the principle causes of this issue is high concentrations of nutrients in the water especially nitrogen and phosphorus. change of land use particularly affected on water nitrate load. therefore, understanding the correlations between land use and nitrate pollutant is a priority in order t...
