Abstract Submission: An increasingly large number of hydrologic systems are not natural but are managed to achieve flood control, water supply, and environmental objectives by water managers. While many of the structural operations used to achieve medium- and long-term (1–30 day) water management objectives in the field are rule-based, some of the operations are still not established as clearly defined rules. They rely on operator experience. Because there are no explicit operating instructions for some of the operations, computer simulation of such systems is difficult. To solve this problem of developing integrated surface-water groundwater models to represent constraints and goals, we developed a structure operation-based optimization method that works with existing hydrologic models using implicit methods. This approach allows us to make use of existing computer models, such as the Regional Simulation Model RSM, and add constraints. The RSM model uses an implicit TVDLF method to simulate hydrology.
This approach of adding operational constraints and targets to existing simulation models is tested in the C-111 canal in Miami, Florida. The canal is used for flood relief as well as water supply. The results show that this approach provides unique and acceptable solutions to difficult problems, and eliminates the need to use iterative methods or formulate the entire problem as a constrained optimization problem.
