These proceedings identify and assemble information on recent applications of mini- and microcomputer technology to problems in urban stormwater and flood management. Instrumentation and data management are reviewed with respect to watershed management and flood forecasting. Computer applications of hydrologic modeling are reported. Hydraulics and water quality models using microcomputers and programmable calculators are presented and applied to urban flooding and runoff and river plume models. Real-time control is reviewed in application to urban runoff forecasting, flood forecasting, and reservoir operation. Implications for the future are discussed, covering software, expert systems and interactive processing.
