Hydraulic Properties of Surface Runoff on Ash-Mixed Concrete Pavement
The disposal of incinerated sludge ash from wastewater treatment plants is becoming an increasingly difficult problem in highly populated cities. The feasibility of reusing sludge ash...
Fort Bend County Surface Water Supply Study
Fort Bend County encompasses approximately 876 square miles in southeast Texas near the Gulf of Mexico. The County's sole source of potable water is groundwater, which supplied 28 million...
Surface Water Withdrawal Permits Programs for Humid Regions
In humid regions of the U.S., where control of surface water withdrawal is traditionally under the riparian doctrine, there are few strong regulatory programs to restrict water use. In...
Determining Optimal Parameter Dimensions for Water Distribution Network Models
Water distribution systems contain a large number of pipes whose roughness factors are unknown prior to model calibration. During the calibration process, pipe roughnesses for each link...
