摘要/Abstract

摘要： 针对多闸坝河网水流控制特征，以MIKE11 HD和AD模块的水量-水质模型为基本模块，通过水位-流量关系及其水位控制，体现闸坝调度对河网水动力及其水质的影响，构建了多闸坝河网水系最大日负荷（TMDLs）计算系统，并应用于淮河流域江苏省沂沭泗水系。利用2006年-2008年及2010年水文、水质监测资料对计算模型的率定与验证。验证结果为：计算区域板浦、沭阳闸下站水位计算值和实测值平均相对误差为0.45%和0.91%，仲集和沭阳（南泓）站CODMn和氨氮的计算值和实测值平均相对误差分别为4%~7.1%和6.5%~20.4%。以2010年（平水年）为设计水文条件，研究区内主要水质受限水体CODMn与氨氮最大日负荷年总计值分别为25276.85t和1932.56t。

Abstract: In according with the flow control characteristics of river networks with multi-sluices,amodelforcalculating Total Maximum Daily Loads(TMDLs) was built based on MIKE11 HD and AD modules. The model reflects the hydrodynamic and water quality influences of dam operation through stage-discharge relation. The Yishusiriver system in Jiangsu province was selected as a typical study area, and the calculation model system for TMDLs process was tested in this area. The results showed that the average relative error of calculated water level was 0.45% and 0.91% at Banpu and Shuyangzhaxia stations, respectively. The average relative errorof the calculated CODMn and NH3-Nwere 4%~7.1% and 6.5%~20.4% at Zhongji and Shuyang (South Channel) stations,respectively.Taking 2010,a normal flow year as the design hydrological year,TMDLs of COD and ammonia nitrogen in the limited water bodies were 25276.85 ton and 1932.56 ton.
