Integrated Hydrological/Ecological/Economic Modeling for Examining the Vulnerability of Water Resources to Climate Change
A methodology for assessing regional-scale hydrologic vulnerability to climate variability which incorporates ecologic and economic factors is presented. A simple economic model of damages...
Adapting Water Resources of the Canadian Prairies under the impact of Climatic Warming
Given that future droughts could become more frequent and more severe because of climatic warming, this paper discusses some strategies to manage and to develop the water resources of...

Problem and Technical Solutions: The Seven Oaks Dam, Physical Elements of the Seven Oaks Dam Feature
Seven Oaks Dam is located in the upper Santa Ana Canyon approximately 1 mile from the canyon mouth. The site is 8 miles northeast of the city of Redlands in San Bernardino County on the...
Expected Moments Alogrithms for Flood Frequency Analysis
The Expected Moments Algorithm (EMA) is a new but conceptually simple approach for the treatment of nontraditional data in flood frequency analysis. Nontraditional data includes censored...
Beneficial Aspects of Flood and Rain in Countries Where the Drinking Water is Naturally Contaminated with Fluoride Where Fluorosis is a Major Public Health Problem
Floods, although considered destructive, have beneficial aspects too. This report is about one such instance where flood waters are considered extremely beneficial in countries where drinking...
Aspects of River House Cleaning during Floods
In spite of all the destructive forces of floods, the washing and scouring of polluted bottom deposits during spring floods gives the rivers a new start at the beginning of what is usually...
Pier Scour at Wide Piers
Scour at relatively wide piers in shallow water is not explicitly accounted for in the current HEC-18 scour equation. The scour estimated for this case is often overpredicted. In this...
Scour around Exposed Pile Foundations
Laboratory experiments were conducted to measure local scour around exposed pile groups for a variety of conditions including different spacings, different skew angles, different patterns...
Modeling Groundwater Contaminant by Unstructured FVM
This study focuses on the numerical solution of the integral form of transport equation on unstructured grids. The algorithm is developed in direct finite volume concept and constructed...
Discussions of a 3D Numerical Simulation of Transient Regional Groundwater Flow and Transport
A 3D numerical model of a groundwater flow and transport was developed to study the movement of radionuclides in the Savannah River Nuclear Site, South Carolina. The modeling effort has...
Effects of Ignoring Well Losses on the Specific Capacity Function
This paper combines these equations with the traditional step-drawdown equation to generate a more realistic relationship among discharge, specific capacity, and drawdown. Under both confined...
Delineating Subsurface Contamination Using Geostatistical and Non-Intrusive Geophysical Methodologies
Electromagnetic (EM) conductivity surveys are becoming a more practiced technique in screening for contamination of soil and groundwater. This non-intrusive geophysical approach detects...
Central Artery/Tunnel (CA/T) Project Environmental Permitting
The Central Artery/Tunnel Project is one of the largest public infrastructure projects in the United States. As such it poses major environmental planning and design challenges. The environmental...
PCE in Dewatering Flows?A Case Study Risk-Based Clean-Up Action Levels
Up to 70 micrograms per liter (?g/L) of tetrachloroethylene (PCE) was detected in dewatering flows associated with a construction project (Project) in the City of Los Angeles. Because...
Technical Activities in a Large Branch or Section
The Texas Section of the American Society of Civil Engineers (ASCE) is currently one of the largest Sections in the Society. Similarly, the Houston Branch is one of the two largest Branches...
Organizing a Local Water Resources Technical Group
Participating in a local water resource technical group can be rewarding professionally as well as socially. However, if such a group does not exist in your area, organizing one is an...
The Birth and Success of Orange County's Hydrology and Hydraulics Technical Group
The Orange County.s Hydrology and Hydraulics Technical Group (HHTG) has been very successful ever since it was founded in 1991. The HHTG is incorporated as a Technical Group under the...
Searching for Optimal Combinations of Stormwater Detention Basins
Hydrology of urban areas is dominated by two distinct characteristics: (1) a preponderance of impervious surfaces created primarily by pavement and roofs, and (2) the presence of constructed...
