Ethanol is playing a key role in current discussions on energy, agriculture, taxes and the environment. This work addresses the potential environmental impacts and behavior of subsurface fuel-ethanol releases. A continuous-flow ...

This study evaluates a 1D and a 2D method for analyzing the combined effect of inland rainfall and hurricane-induced storm surge on a coastal floodplain. Horsepen Bayou near Clear Lake, southeast of Houston, Texas is ...

This study uses a distributed hydrologic model to assess the impact of wetland loss on flood peaks. There is large agreement among hydrologists that wetlands have significant flood-mitigation potential. However, the lack ...

Use of a standard three-dimensional flow model to simulate the saltwater interface in coastal and island aquifers as a no flow boundary is introduced. The method was used to simulate flow in a generic circular island ...

A multiphase unsaturated zone contaminant transport (MUCT) model has been developed to simulate the simultaneous vertical flow of water and a second immiscible fluid in unsaturated porous media. The model couples multiphase ...

The design and performance of soil vapor extraction (SVE) systems can be evaluated using mathematical models. A lack of knowledge in how to select the appropriate model and use it properly for field settings are major ...

The present research employs remote sensing data and advanced hydrologic modeling to improve the spatial representation of an urban watershed, Whiteoak watershed, located northwest of downtown Houston, TX. During the last ...

The availability of high-resolution LIDAR and GIS data combined with the onset of more powerful computers has made the use of distributed parameter hydrologic models more feasible. This study employs one such model, Vflo(TM), ...

A Decision Support System is a class of computer software with information, databases, and computer models integrated together to help people solve broad, semi- structured problems. Ground water contaminant transport ...

The United States coastline contain some of the most valued ecological resources, the most populated urban areas, the most complex infrastructure systems, the most prolific economic engines, and the busiest ports of trade. ...
