Public Attitudes, Behavior, and the Willingness to Sacrifice to Mitigate Uncertain Adversity: Water Management Implications for Climate Change
Although several scholars have touted the emergence of a new environmentalism, many Americans seem to make decisions that do not reflect green thinking. Examples include driving more miles...
Stormwater Management Plan Updated for Climate System Changes
When large watershed stormwater management plans are updated, climate system change factors due to global warming effects should be considered. Climate system changes may cause changes...
A Study into Effectiveness of Urban Best Management Practises
The author present an ongoing research project into the effectiveness of two wetland Best Management Practises. The research methodology and site setup are presented. The research objective...
Testing and Effectiveness of a New Urban BMP Storm
Stormwater management for water quality control, pollution prevention and pretreatment can be a difficult problem for the development design professional, a costly and time consuming problem...
Floodplain Analysis of the Lower Santa Margarita River in Camp Pendleton Marine Air Base, California
Floods of 1993 caused extensive flooding of the Santa Margarita River, and significant damage to Camp Pendleton. A floodplain analysis was performed including an assessment of recent flood...
Modeling the Ecological Impacts of Flaming Gorge Dam Operations
Hydropower operations at Flaming Gorge Dam on the Green River in Utah, U.S.A., can produce rapid downstream changes in flow and stage during a day. These changes can, in turn, affect ecological...
Optimization and Simulation in Design and Operation of Reservoirs
Due to stochastic nature of rivers, their volumetric yields are random variables. Spatial and temporal redistribution of Water makes the reservoir construction a must. Therefore, water...
Roanoke Valley Flood Hazard Mitigation
Dewberry & Davis is under contract to the Fifth Planning District Commission (5th PDC) to prepare the Roanoke Valley Regional Stormwater Management Plan. The Plan, which will address...
Management of Contaminated Groundwater Using Natural Attenuation
Many state and federal regulations governing remediation of contaminated groundwater give preference to the implementation of remedial alternatives which are capable of providing protection...
Evaluation of Potential Impacts to Endangered Species that Use Wetland Areas: A Case Study
A proposed runway extension in an airport adjacent to a large riverine system and containing a small perennial branch of the riverine system would result in loss and modification of forested...
Emergency Repair of an Ocean Outfall
The County Sanitation Districts of Orange County (Districts) provide wastewater collection, treatment and disposal services for more than 2 million people in metropolitan Orange County....
Biological Serendipity from an Ocean Outfall Maintenance Inspection
A large deep-water ocean outfall discharging ?880 x 106 liters day (230 million gallons day of treated wastewater effluent was inspected with a one-man...
External Inspection of an Ocean Outfall
In October and December, 1994, an external inspection was performed on the County Sanitation Districts of Orange County's (Districts) ocean outfall. This presentation describes...
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...
