摘要
根据官厅水库狭长、水浅和水文、水力、水质迁移扩散等特点与河流相似的事实，采用一维Ｓｔ．Ｖｅｎａｎｔ方程组模拟其水流状况；采用完全混合反应器概念模拟其水质变化，两者的藕合就构成了官厅水库的水质模型。该模型在模拟官厅水库ＮＨ３－Ｎ浓度时空变化时，精度令人满意，并已用于官厅水库的水质预测和水质管理。
channel” reservoirs whose
profiles are characterized as being wide and shallow, do not demonstrate gradation
phenomena, so it can be assumed that pollutes entering into “channel” reservoirs
mix with water completely. In this paper, the flow simulation model for “Channel”
reservoirs was developed by solving one dimensional Saint Venant equations in
Preissman weighted four points implicit scheme and the water quality simulation model
for “channel” reservoirs was developed by solving water quality equations employing
the concept of full mixed reactor. The flow/water quality simulation coupled model was
used to simulate the water quality situation for “channel” reservoirs. The flow/water
quality simulation coupled model is of clear concept, concise structure and was used in
the Guating Reservoir(“Channel” reservoir) to simulate the transaction of NH 3-N with
satisfied results. This model can be used for environmental impact assessment, water
quality prediction and management in the Guanting Reservoir.
