Storage-Reliability-Resilience-Yield Relations for Northeastern United States
An evaluation of time-series of streamflow at 166 basins in the northeastern United States reveals that this region is remarkably homogeneous in terms of the year-to-year variability and persistence o...
Estuary Management by Stochastic Linear Quadratic Optimal Control
A new type of estuary-management model based on discrete-time stochastic linear quadratic optimal control is presented. It is a feedback-control model that enables decision makers to determine the ups...
Apersonal computer (PC) based decision-support system (DSS) can provide real-timeinformation for improved flood prevention and control in the TrinityRiver basin in Texas. The DSS components (1) retrieve, process,and file rainfall and streamflow data; (2) estimate basin averagerainfall, update model parameters, and forecast runoff; and (3) simulatereservoir operation in order to forecast regulated flows basinwide. TheDSS uses custom software for retrieving and processing the dataand an industry-standard database-management system (DBMS) for filing the data.It uses specialized versions of the well-known programs HEC-1 andHEC-5 for forecasting runoff and simulating reservoir operation, respectively. TheDSS integrates these components with a specialized program manager. Althoughnot yet used as designed, potential improved flood prevention andcontrol with the DSS are demonstrated with historical storm data.
