Abstract
The purpose of this study is to integrate the resources of Irrigation Association and Environment Protection Agency. Utilize the sampling data of water and sediment in irrigating channels to establish the model of water pollutant transportation, and based on the sampling data and statistical methods to analyze the correlation between the electrical conductivity and concentration of heavy metal ion in the irrigation water. According to the results, water pollution in this area caused by copper pollutant. According to previous studies, Water Quality Analysis Simulation Program (WASP) has been widely applied in large-scale watersheds and river, but rarely applied in small-scale irrigation channels. This study utilized WASP model to establish copper ion transport and evaluate the assimilative capacity of irrigation channels. By calculate the annual accumulating rate of heavy metal pollutant in downstream farmland and evaluate current polluted situation, suggest improvement countermeasures to assure the safety of agricultural products. ? 2018, Taiwan Agricultural Engineers Society.
