Welcome to the Hydrologic Engineering Center's web page for our Prescriptive Reservoir Model program, HEC-ResPRM. HEC-ResPRM is a reservoir system operations optimization software package
developed to assist planners, operators, and managers with reservoir operation planning and decision-making. HEC-ResPRM uses network flow optimization to suggest an idea of the best
outcome that can be expected for the system based on any particular prioritization of the system objectives and given inflow time-series.
Optimization is the approach to solving problems that seeks the best solution by maximizing (or minimizing) a set of goals in the form of an objective function, subject to specified constraints.
Reservoir operation takes into account a number of goals from different interests (flood control, water supply, power generation, recreation, etc.). HEC-ResPRM allows users to pose a reservoir
system as a network flow problem. Users create a network schematic of their watershed's reservoirs and stream reaches. They then enter hydrologic data and penalty functions for each reservoir
and reach, representing the cost/benefit of each interest in terms of penalty and flow/storage. HEC-ResPRM then uses a network flow solver to find an optimal solution. Users can view optimization
results in graphical and tabular format directly within the graphical user interface.
HEC-ResPRM runs on a monthly time step and can be used alone or in conjunction with simulation software such as HEC-ResSim to analyze and improve reservoir operations. HEC-ResPRM can be used
to maximize benefits to a variety of goals, demonstrate a best case scenario for given priorities, or visualize the interplay among conflicting interests in the watershed. It can be used to
optimize non-monetary values such as ecosystem goods and functions alongside traditional values. HEC-ResPRM is also a useful tool for communicating with stakeholders – allowing them to view
tradeoffs between different system objectives.
The purpose of this site is to enhance the support services we provide to our customers. We’ve provided a number of resources here to help you download software, resolve problems, report bugs,
and suggest improvements to our products.
