Pure Simulation RiverWare's simulation algorithm solves upstream, downstream, or any well-determined combination of these in a single run. Input/output data combinations are flexible, allowing various combinations of, for example, storage, pool elevation, releases, energy and inflows as inputs to drive the simulation. Value-added Features:   • The solution can progress forward or backward in time, as the data requires. This allows for meeting future storage targets or solving for upstream releases to meet downstream future demands.   • The object-oriented modeling approach makes it easy to find where your model may be over- or underdetermined.   • Advanced diagnostic utilities provide detailed information about the progress of the solution at each timestep, making it easy to analyze runs. ☼ Last edited October 16, 2015 ☼
