Abstract: Results from five physical hydraulic model studies of riverside water intakes situated along the Missouri River reach between Sioux City, Iowa, and St. Louis, Missouri, are presented. Movable-bed, undistorted Froude-scale ...

Abstract: Distributed, physically based watershed and irrigation advance models require robust infiltration estimation capabilities. The empirical Green and Ampt (GA) equation of infiltration is a popular method for estimating ...

Abstract: The advantages of bentonite clay for sealing applications are well known. Bentonites have extremely low permeability, do not affect formation water chemistry, and have the ability to swell and deform in response to subsurface ...

Abstract: Shear strength tests are conducted in a model of a water, well on four, commercially available, granular bentonite well sealing products. The time dependency of annulus seal shear strength and resistance to piping is ...

Abstract: The need to simulate surface water flows in watersheds with diverse runoff production mechanisms has prompted the Department of Defense to invest in the development of a new, physically based hydrologic model, called the ...

Abstract: Runoff data were analyzed from the semihumid 21.2 km

Abstract: Statistical analyses were performed using five years (1996–2000) of Weather Surveillance Radar–1988 Doppler (WSR-88D) weather-radar rainfall estimates that were produced for the Global-Continental Scale International Project ...

Abstract: The increasing proliferation of spatial data, geographic information systems (GIS), and models for hydrologic applications provide many new investigation opportunities but also present a number of challenges for the ...

Abstract: This paper presents representative applications and models that can take advantage of spatially distributed data in a geographic information system (GIS) format for watershed analysis and hydrologic modeling purposes. The ...
