Plug-and-Play Integration of Watersheds in the Regional Simulation Model, Part II: Regional Resource Assessment with SFRRM/SFWMM Routing

The Regional Simulation Model (RSM) is a regional hydrologic model developed by the South Florida Water Management District (SFWMD). The RSM is an object-oriented model that is capable of simulating all of the major components of the hydrologic cycle and the management operations for the complex network of canals and water control structures in southern Florida. Part I of this paper presents a high level description of the model and the "Plug and Play" approach proposed for modeling subregions of interest using a distributed, finite-volme mesh imbedded in a lumped, regional model. The Management Simulation Engine (MSE) component of the RSM provides a platform for simulating a wide range of policies and operations for the water control features in the South Florida system. One approach uses assessors to quantify water supply and flood control needs in the system and traversal methods to impose flow at managed structures across the network of canals. Many of these methods have been developed and used successfully in two legacy models for the same region: the South Florida Water Management Model (SFWMM or 2 x 2) and the South Florida Regional Routing Model (SFRRM). This paper identifies some of the key management methods employed by the SFWMM and SFRRM and describes how they have been reformulated for use in the MSE to coordinate regional and local operations in the detailed finite-volume based mesh models.
