Current decisions concerning water allocation from rivers are constrained by the requirement of maintaining a viable ecosystem in the river or stream. The current practice is to use physical habitat as a surrogate for ecology based on the assumption that if the physical conditions are similar to those used by existing aquatic populations then the ecology will be maintained. Reliable hydrodynamic modeling tools are required to predict detailed depth, velocity and temperature distributions as a function of the stream discharge and geometry.

目前关于从河流分配水的决定受到维持河流或溪流中有生存能力的生态系统的要求的制约。目前的做法是利用自然栖息地作为生态的替代品，其基础是假设如果物理条件与现有水生种群使用的条件相似，则生态将得到维持。需要可靠的水动力模拟工具来预测作为水流流量和几何形状函数的详细深度、速度和温度分布。
