MODSIM is a generalized network flow model designed to simulate the physical, hydrological, and institutional features of river basins operating under the Prior Appropriation Doctrine. The intuitive graphical user interface allows the user to perceive system relationships that often go undetected in 'black box' simulations. Complex operational aspects of a water resources system, such as water rights, storage accounts, and river exchanges in the network can be represented explicitly with MODSIM's advanced functionality.

Understanding the complexity surrounding water rights, water administration, and water accounting, Riverside Technology, inc. (RTi) engineers have successfully implemented and applied river basin/water right models using MODSIM on various water resources projects, ranging in scope from international river management to municipal water supply investigations. We understand the benefits of broad basinwide analysis as well as the importance of precise water accounting. Our experience allows us to identify the underlying issues on a case by case basis, select the appropriate analysis tools, both customized applications as well as standard software packages, and provide a comprehensive picture of the water resources system. In many cases, we also have developed customized pre- and post-processing utilities to assist with data management and analysis, and interpretation of results.
