Real-Time Rainfall Monitoring-Prediction System and Urban Hydrologic Operations

During a 4-year period (1975-1979), a comprehensive hydrometeorological research program was carried out in the Chicago metropolitan area to develop better methods of utilizing meterorological data in the design and real-time operation of urban hydrological systems. A real-time monitoring-prediction rainfall system was developed and tested to facilitate and improve operations of urban storm-sanitary sewer systems during heavy rainstorms. Basically, this system involved the combination of a dedicated weather radar with associated data processors and computers, used in conjunction with telemetered raingage data. The demonstration proved successful and indicated that the system can provide very useful meteorological input which should lead to substantial improvement in the real-time operation of urban hydrologic systems, particularly in large metropolitan areas having complex operating problems during heavy rainstorms.
