Using a GIS to link digital spatial data and the precipitation-runoff modeling system, Gunnison River Basin, Colorado Using a GIS to link digital spatial data and the precipitation-runoff modeling system, Gunnison River Basin, Colorado
The U.S. Geological Survey Precipitation-Runoff Modeling System, a modular, distributed-parameter, watershed-modeling system, is being applied to 20 smaller watersheds within the Gunnison River basin. The model is used to derive a daily water balance for subareas in a watershed, ultimately producing simulated streamflows that can be input into routing and accounting models used to assess

Variation of froude number with discharge for large-gradient steams Variation of froude number with discharge for large-gradient steams
Under chemical-control conditions, the Froude number (f) for a cross-section can be approximated as a function of the ratio R2/ 3/d 1/2 , where R is the hydraulic radius and d is the average depth. For cross sections where the ratio increases with increasing depth, F can also increase with depth Current-meter measurement data for 433 streamflow gaging stations in Colorado were reviewed...

Water-level, velocity, and dye measurements in the Chicago tunnels Water-level, velocity, and dye measurements in the Chicago tunnels
On April 13, 1992, a section of a 100-year-old underground freight tunnel in downtown Chicago, Illinois was breached where the tunnel crosses under the Chicago River, about 15 meters below land surface. The breach allowed water from the Chicago River to flow into the freight tunnels and into buildings connected to the tunnels. As a result, utility services to more than 100 buildings in...

A geographic information systems technique for monitoring contaminants in Galveston Bay, Texas A geographic information systems technique for monitoring contaminants in Galveston Bay, Texas
A geographic information system (GIS) was used to compile a series of databases containing details concerning metal contamination and pollution sources to study their impacts on the Galveston Bay (TX) ecosystem. Using these databases, a series of maps with various overlays was created with ARC/INFO software. These maps allowed patterns of spatial distribution of numerous variables to be...
