A Stormwater Management Plan
Part 2 of the National Pollutant Discharge Elimination System (NPDES) Stormwater Permit requires both sampling and analysis of stormwater and the control of illicit discharges to stormwater...
Rainfall-Runoff Modeling for Watershed Stormwater Management
In the design of watershed stormwater management plans used for land development, the Pennsylvania State Runoff Model (PSRM) presents upstream subbasin flows that contribute to the peak...
Direct Sizing of Small Stormwater Pump Stations
Pump stations are components of stormwater drainage systems that remove collected storm runoff from locations where drainage by gravity is not feasible. Usually pump stations will operate...
Managing Sediments in Reservoirs at FERC
Reservoir siltation has negative effects on water resource development projects. The impact of sedimentation on FERC's licensed hydropower developments is often quite significant....
Emerging Concepts for Management of Salinity and Drainage in Irrigated Regions
The purpose of this paper is to very briefly highlight some physical and design concepts important to management of salinity and drainage in irrigated regions in an environmentally sensitive...
Shallow Ground Water Management with a Modified Subsurface Drainage System
An existing subsurface drainage system was modified to control the flow from the drain laterals and to control the water table depth on a portion of the field. Tomatoes and cotton have...
Efficiencies of Drainage Systems and Improved Water Management
Drainage of agricultural lands has become a contentious issue as concern increases over the actual economic benefits of subsurface drainage in irrigated regions relative to the impacts...
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...
Santa Ana River Mainstem Project
The Santa Ana River Mainstem Project consists of seven major features including the construction of 550 ft. high earth and rockf ill dam; raising the embankment by 28 feet of Prado Dam,...

1. Need for additional flood control in Orange County. A. Orange County flood history. B. Increasing Population and development. C. Santa J River flood threat today. 2. How the Santa Axia...
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...
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...
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...
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...
The Treatment Train Detention Concept
With the recent concern for nonpoint source pollution impacts to receiving waters, the Village of Saukville, Wisconsin took advantage of state funding grants to conduct a Stormwater Management...
Effective Subsurface Retention/Detention Systems
Stringent environmental regulations and increasing land values have made finding an effective way to manage storm water runoff a high priority for consulting engineers and land developers....
Calibration of Sediment Transport Model for the Upper End of Elephant Butte Reservoir
Elephant Butte Reservoir is located about 125 miles north of El Paso, Texas on the Rio Grande. The reservoir is approximately 35 miles long with a narrow neck, called the Narrows, about...
