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.

目前有关河流水分配的决策受到维持河流或溪流中可行的生态系统的要求的限制。目前的做法是使用物理栖息地作为生态的替代，其假设是如果物理条件与现有水生种群使用的条件相似，那么生态将得到维持。需要可靠的流体动力学建模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。
