摘要
应用WASP 7模型的EUTRO子模块对淮沭新河东海段的溶解氧(DO)和化学需氧量(COD)指标进行模拟研究,采用2014年与2015年的水文、水质数据进行模型参数率定,并以2016年1月—2017年9月的水质数据进行验证,验证结果为DO和COD的模拟值与实际值的相对误差分别能控制在15%和10%以内,线性回归分析结论显示相关系数R2均在0.9以上,表明两者的吻合度较高。
Simulation study of the water quality in Lianyungang section of Huaishuxin River was carried out using WASP7 model.Water quality indices in this study included:Dissolved oxygen(DO)and Chemical oxygen demand(COD).The measured values of Lianyungang section of Huaishuxin River in 2014 and 2015 were used to calibrate and check the simulated values.Results showed that as for the simulated values the relative error of DO was below 15%,and of COD was below 10%in a specific time period from January 2016 to September 2017.The results of the linear regression analysis showed that the correlation coefficient R2 was above 0.9,indicating a high degree of anastomosis between the simulation values and the measured values.
