Design Considerations Associated with Bioretention Practices
This paper presents the design requirements of bioretention practices. Bioretention is a stormwater management practice using a combination of retention, native terrestrial vegetation...
Pollutant Removal Efficiency of Detention Basins
A simple method is presented for quick estimates of pollutant removal efficiency of detention basins under dynamic conditions. The method is based on the generalized solutions to the reservoir...
Long-Term Performance of Wet Detention Ponds
Wet detention is a technology which has been successfully applied in recent years to improve stormwater runoff quality in urban areas. Since most systems have a short operational history,...
Biological Modeling in the Columbia Basin: An Organized Approach to Dealing with Uncertainty
Development of the Columbia River basin has had a profound impact on its natural resources, particularly species of Pacific Salmon. Passage of the Northwest Power Act of 1980 put in motion...
The Development and Use of Policy Statements in River Simulation Models
There are a number of ways in which the physical operation of a river system can be expressed in simulation models. Most of the earlier simulation models have incorporated the operating...
The Law of the River: Policy Expression
The need to accurately represent the law of the Colorado river has heretofore precluded the use of any general purpose river basin simulation model. In order to overcome the inflexibility...
RSS: A Construction Kit for Visual Programming of River Basin Models
With the ever increasing pressure on environmental resources, there exists strong interest in river basin models which can be used to simulate proposed policy alternatives. Traditionally,...
Evolving Institutions for Managing the ACF Basin
The ACF basin is a case of interstate conflict in resource management. This study looks at the planning underway with regard to mechanisms for managing the basin....
Estimating Maintenance Cost of Existing Stormwater Retention Ponds
The 280-acre Kensington Business Park includes 11 stormwater retention ponds that were also designed to provide aesthetic enhancement. Maintenance of these ponds became a concern when...
A Watershed Approach to Water Quality Criteria
Water quality has been managed historically using water quality criteria implemented through the NPDES permitting process. Many water bodies have water quality better than that defined...
A Methodology for the Evaluation of Global Warming Impact on Soil Moisture and Runoff
Global warming is expected to increase the intensity of the global hydrologic cycle. Precipitation and temperature patterns, soil moisture requirements, and the physical structure of the...
The Challenges of Interstate Water Planning and Management
This study is one of four primary basin studies as part of the U.S. Army Corps of Engineers National Study of Water Management During Drought, a four year study initiated after the Drought...
Demonstrating Competition for a Limited Resource in the Cedar/Green Basins
An object oriented model building tool is used to develop two river basin simulation models. The models will be used to help manage the water resource during dry years in the Cedar and...
Optimum Operation of Recharge Basins
Mathematical models based on nonlinear programming are developed for operating recharge basin systems. The objective of these optimization models is to determine the operation policy that...
Artificial Recharge to Manage Groundwater Quality in a Connected Surface Water Groundwater System
Finite difference method is used to formulate the management problem of movement of water and solute in a connected surface water groundwater system. Pumped groundwater quality of conservative...
Large-Scale Conjunctive Use of the San Gabriel Basin: An Environmentally Beneficial Water Supply Project
The 170-square-mile San Gabriel Basin in Los Angeles County, California, has commanded the attention of both water supply and environmental agencies because: (1) it is an idyllic natural...
Salinity-Colorado River Water Quality Crisis
The major concern cited is excessive salt concentrations caused by salt loading of return flows to the Colorado River. Salinity levels measured as milligrams per liter (mg/L) are monitored...
The Dynamic Geomorphology of Yangpu Bay, Hainan Island, China
Yangpu Bay is located in the northwest of Hainan Island. It consists of Yangpu Bay (outer bay) and Xinying Bay (inner bay). During 1983-1989, we carried out a series of research into the...
From Planning to Construction in Coastal Louisiana (With a Cast of Thousands)
In light of the 25 square mile loss of coastal wetlands in Louisiana, the Coastal Wetlands Planning, Protection, and Restoration Act mandates that a interagency Task Force develop a comprehensive...
Transformation of the Black Sea Coast and Shelf by Wave Erosion in Pliocene-Pleistocene
Theory of transformation of coast and shelf of the ancient and modern seas by waves is presented. It allows to work out a scheme of adjoining land and shelf evolution on the basis of basin...
