Abstract:

The Corps of Engineers has a need for radar information to enhance rain gauge measurements in determining average rainfall over a particular basin for hydrological forecast models used in reservoir control. Spatial distribution of rainfall has always been difficult to determine from rain gauges alone since the rain gauge networks are sparse due to problems associated with the cost to install, maintain, and retrieve data on a real-time basis. The nature of thunderstorms also limits expectations of rain gauges since rain does not normally fall in uniform amounts over a river basin in convective thunderstorms.
