Integration of a surcharged pipe model and an overland flow model for flood prediction in a highly urbanized area
Two models were incorporated to evaluate the hydrologic and hydraulic behavior of the Harris Gully watershed in Houston, Texas. A HEC-1 model was created and calibrated to three historical storms for average errors of 6% ...
Modeling contaminant partitioning between residual oil and mobile water phases in porous media: A time variant source of contamination
Residual hydrocarbons residing above or within an aquifer can serve as a continuous time-variant source of contamination to the aquifer. The primary mechanism for contamination is the movement of water past the immobile ...
Evaluation of slug tests in a bounded, phreatic, sand and gravel aquifer
The purpose of this research was to compare hydraulic conductivity estimates in a bounded phreatic aquifer derived from slug tests to those calculated from more accurate and costly tracer tests. A slug test is a simple ...
Flood estimation in a highly urbanized watershed using advanced radar (NEXRAD)
Advanced radar (NEXRAD) was used for collection of rainfall data over Brays Bayou in Houston, TX for the storms in October 1994 and January 1998. The radar rainfall data was calibrated to the rain gauge system within the ...
The effects of representing the spatial variability of aquifer characteristics on numerical ground water flow and contaminant transport modeling
The objective of the research presented here is to determine how the representation of the spatial variability of aquifer properties affects ground water flow and contaminant transport modeling at the United Creosoting ...
A new method for the real-time prediction of flood peak discharges in Brays Bayou, Houston, Texas
A new method for the prediction of maximum flood stage discharges in real time that does not rely on rainfall data has been developed for the Brays Bayou drainageway in Houston, Texas. A study of 21 historical storm discharge ...
