AB: Hydrologic modeling of surface water reservoirs is an effective tool in evaluating different water management options for addressing regional water issues in Florida. However, modeling reservoir water dynamics could be challenging because of the difference in scale between canals and the entire reservoir. Water pumped into the reservoirs is first discharged into canals inside the reservoirs, which distributes the water. The canal eventually overflows and water floods all the reservoir. Two modeling approaches to simulate this process were tested on two reservoirs using the integrated MIKE-SHE and MIKE 11 model. The first approach simulates the 1- D flow in the canal in a link-node model and once water floods, it is modeled as 2-D flow. The second approach simulates the entire impoundment as a canal. In both reservoirs, Modeling Approach 1 resulted in overestimation of peaks and poor results. Modeling Approach 2 showed considerable improvements in the results and a satisfactory match between observed and simulated water levels. The difference is attributed to the difficulty in representing the canal flooding process in hydrodynamic models.
