Modeling 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 کاملLand use pattern optimization based on CLUE-S and SWAT models for agricultural non-point source pollution control
Improper land use is one major cause of non-point source pollution. Integrated modeling would support the evaluation and optimization of land use for the non-point source pollution control. In this study, the CLUE-S (the Conversion of Land Use and its Effect at Small regional extent) and SWAT (Soil and Water Assessment Tool) models were coupled to simulate pollution loads under different land u...
متن کاملIntegrating Ecological Restoration of Agricultural Non-Point Source Pollution in Poyang Lake Basin in China
This study addresses the excessive consumption of river basin water from the Poyang Lake area in China. Consumption of water for irrigation, together with the discharge of agricultural non-point source pollution, is seriously affecting the water quality of Poyang Lake. This study assesses the application of integrated ecological restoration technology for agricultural non-point source pollution...
متن کاملمدل سازی آلودگی غیرنقطه ای با استفاده از سیستم اطلاعات جغرافیایی (GIS) برای ارائه بهترین شیوه های مدیریت (BMP) در حوضه آبخیز گرگانرود
The most important pollutants that cause water pollution are nitrogen and phosphorus from agricultural runoff called Non-Point Source Pollution (NPS). To solve this problem, management practices known as BMPs or Best Management Practices are applied. One of the common methods for Non-Point Source Pollution prediction is modeling. By modeling, efficiency of many practices can be tested before ap...
متن کاملAgricultural Non-point Source Pollution Load Estimation Method in Haihe River Basin
the agricultural non-point source pollution shows some special features such as dispersion, randomness, fuzziness and cumulative compared with industry and other point source pollution. Owing to lacking complete and systematic data on agricultural sources of pollution in the long-term, Agricultural non-point source pollution load of the new method "IS (Investigation-Statistics) estimation metho...
