通过地表径流和洪水输移的地面污染物是特拉华河流域农业土地资源管理最主要的问题。卡茨基尔是为纽约市供水的多功能水库的基地。由于库水受到来自洪泛区农业污染物的污染 ,需要对污染源作风险量化分析。为了评价 1a中不同时期河水漫滩淹没的风险 ,对 7个水文测站的河道流量资料进行了分析 ,得出月部分历时与最大历时系列资料。这对根据洪泛区土壤内污染物输移的水文风险作出决策具有重要意义 (如该信息可用于确定农田施肥造成地表水污染的风险 ,并提出减少这种风险的计划 )
Ground pollutants transported by surface runoff and floods are the most important issues in agricultural land resource management in the Delaware River Basin. Catskill is the base for a multi-purpose reservoir that supplies water to New York City. As the reservoir water is contaminated by agricultural pollutants from the floodplain, quantitative analysis of the risks of pollution sources is needed. In order to evaluate the risk of river floodplain flooding in different periods of 1a, the data of river flow of seven hydrological stations were analyzed and the monthly part-time and the maximum time-lapse data were obtained. This is important for making decisions based on the hydrological risk of pollutant transport in floodplain soils (eg, this information can be used to determine the risk of surface water contamination from fertilization of farmland and to propose a plan to reduce the risk)
