4、时的起始条件，起调水位357m；(c) 本次调洪计算采用水能规划书中介绍的列表试算法计算，依据书中所给的水库洪水调节原理，采用水量平衡方程式，当采用开敞式溢流时，可利用下式计算 。调洪演算方法在洪水来临前，用闸门控制下泄流量，让水库保持在起调水位357m，河流来流量继续增大于是闸门全开。先假定一个水位，根据，可以确定下泄流量，然后根据采用水量平衡方程式求出V后,从而求出了时段末的库容，再根据库容曲线Z-V可以求出计算水位，从而与假定水位对照如果其与假定水位相等则试算完毕，否则重新假定水位重复上面的过程直到两者相等。1.3调洪的基本资料起调水位357m1.4 调洪演算过程 方案一时间t设计流量平
