GIS and SWMM Applications in Developing the Lake Houston Watershed Management Program
The City of Houston has undertaken the task of developing a Watershed Management Program for the 2,828 square mile lake Houston Watershed in an effort to prevent future degradation of...

A Flexible Curtain Structure for Control of Vertical Reservoir Mixing Generated by Plunging Inflows
To maintain salmon habitat in the Sacramento River, efforts are being made to pass cold water inflows through Whiskeytown Reservoir, California, with minimal warming. In Whiskeytown, summer...

A Guideline for the Determination of Probable Maximum Flood for Civil Works

Foreign Investment in Latin America: A Second Look
It has become common to hear that Latin America has emerged from the lost decade of the 1980s, a period when virtually every country in the region suffered from high debt, high inflation...

Integration of Chemical and Cement Grouting Techniques for Controlling Mine Water Inflows through Fractured Ground

Expert System for Wastewater Collection System Infiltration and Inflow Mitigation

Evaluating Spillway Adequacy
More than a third of all dam failures are caused by overtopping. Equipment malfunctions or operations errors are sometimes to blame, but the principal cause is inadequate spillway capacity....

Global Climate Change Effects on Water Quality
The annual thermal energy cycle of Shasta Reservoir in California is simulated under scenarios of climate corresponding to present conditions and as predicted by global climate models...

An Approach for Incorporating Inflows Uncertainty in Management Models
Inflow uncertainty is probably the most difficult issue for optimal management of conjunctive use water resources systems. In many instances, the effect of future inflows and their uncertainty...

Hydraulic Risk of Flood Disaster Reduction at Dams

Modeling the Salinity History of Great Egg Harbor Bay, New Jersey

In-Channel Sediment Basins: An Alternative to Dam-Style Debris Basins

Advantages of Installing Influent Fine Screens at a Large Wastewater Treatment Plant

Water Quality and Hydrologic Characteristics of a Wet Detention Pond
A small wet detention pond was instrumented to determine treatment efficiencies. Annual loads showed a reduction from the inflow to the outflow for ammonia as nitrogen (39%), organic nitrogen...

Analysis of Thermal Scanning Imagery to Investigate Point Inflows Into Surface Water Bodies
Using a modified technique of thermal infrared remote sensing, physical sampling, and data analysis (graphical and geostatistical) locating a small inflow to a lake was possible. Thermal...

Use of Computers in the Management of Pecos River Compact
The Pecos River Compact between New Mexico and Texas did not define clearly what New Mexico's delivery obligation was. After a 14-year long litigation in the U.S. Supreme...

Operation of Hydropower Plants Considering Daily Streamflows
Operation of hydropower plants is a sequential decision process often modeled as a dynamic programming problem. Typically, such formulations consider monthly stages assuming that monthly...

Brule Hydroelectric Project Inflow Design Flood Study
In 1987, Wisconsin Electric Power Company (WE) was directed by FERC to provide additional spillway capacity at it's 63-foot (19 m) high Brule Dam. Original spillway capacity...

Hydrologic and Geochemical Approaches for Determining Ground-Water Flow Components
Lyman Lake is an irrigation-storage reservoir on the Little Colorado River near St. Johns, Arizona. The main sources of water for the lake are streamflow in the Little Colorado River and...

Hydraulic Features of Flexible Curtains Used for Selective Withdrawal
Flexible curtain barriers are being investigated as a way to modify power penstock intakes to achieve selective withdrawal. The curtain barrier controls the elevation from which water...
