<br /> <br />PRSYM is a general-purpose, interactive model <br />building tool used to develop water distribution <br />models for: <br /> <br />. short..term operations and scheduiing <br />. mid-term operations and planning <br />. long-term poiicy and planning <br /> <br />PRSYM Is an object-oriented reservoir and river <br />system modeling framework developed by the <br />Center for Advanced Decision Support for Water <br />and Environmental Systems (CADSWES) at the <br />University of Colorado with funding provided by <br />Reclamation, Tennessee Valley Authority (TVA) and <br />the Electric Power and Research Institute (EPRI). <br /> <br />MMS , ThE ModvLAR ModEliNG SYSTEM <br /> <br />MMS is a model building framework to simulate a <br />wide range of interdisciplinary environmental and <br />water resource physical processes, MMS was <br />initially developed collaboratively by CADSWES and <br />the US Geological Survey (USGS). Enhancements <br />are presently being made and supported by the <br />USGS. Components of MMS include: <br />. Pre-processors to access and prepare data, <br />. A library of models and modules to simulate <br />hydrologic and ecosystem processes, and <br />. Post-processors to display and analyze <br />model results. <br /> <br />Basin models may be run using meteorological <br />historic data or input from weather and climate <br />models. Resulting simulated streamflow is used <br />directly by river basin managers or to subsequently <br />simulate alternative operating scenarios. <br />:~'? <br /> <br />o <br />M <br />N <br /> <br />The H DB is a relational data base which <br />includes streamflow, reservoir operations, <br />SNOTEL and other snowpack data and <br />weather data, Data is continually updated <br />automatically trom telemetry, SCADA, and <br />other real-time systems. Ultimately, it will <br />inciude water accounting, water rights <br />information, data and NEXRAD precipitation <br />estimates, HDB Is the key to successful <br />decision making with rapid access to timely <br />information. <br /> <br />Opera.tionalAnalysis and RunoHPrediction Tools <br /> <br />The ability to link other modules to the <br />database (inciuding the modeling <br />components) provides a consistent view of the <br />historical, current, and future predictions. <br />Other modules make it easily to query, <br />analyze, and display this information to the <br />water resource managers, <br /> <br />. Improve precipitation and snowmelt <br />forecasting to allow more effective and <br />efficient river basin management <br />. Determine Available Water in the River Basin <br />System <br />. Predict short-term (12 to 48 hour) supply and <br />flood threats <br />. Estimate long term (1 to 12 month) probable <br />supplies (10,50, 90% exceedence) for <br />Annual Operations Plans <br />. Simulate long term (10 to 85 year) river basin <br />management scenarios (using historic and <br />stochastic streamflow data) <br />. Water scheduling for: <br />1.
