Development of Transport Model for Groundwater Planning and Management in Taipei Basin
The objective of this paper is to develop a groundwater model for contaminant transport simulation. The transport model, in conjunction with the previously developed flow model, is used...
Flood Monitoring Network In Southeastern Louisiana
A flood monitoring network has been established to alert emergency operations personnel and the public about hydrologic conditions in the Amite River Basin. The U.S. Geological Survey...
Energy Dissipation for a RCC Stepped Spillway
A two-dimensional physical model study was used to quantify the kinetic energy dissipation of the steps in a roller compacted concrete (RCC) stepped spillway. The steps were effective...
A New Formula for Mean Velocity in Torrents
In this paper we present a new equation for mean velocity in torrents based on travel time measurements and geomorphological relations. Here, the emphasis is not on understanding the physical...
Determination of Sediment Profile for a Dry Flood Control Basin
A modification of the standard delta profile method was used to estimate the sediment profile in a dry flood control basin. Dry flood control basins do not have a normal operating pool...
Scour Hole Depth Downstream of the SAF stilling Basin
A Model to predict the maximum local scour depth downstream of the SAF stilling basin is presented. The model is based on stability analysis of a particle attacked by the hydrodynamic...
Three-Dimensional Simulations of Ground Motions in Sedimentary Basins
This report describes work being done at the U.S. Geological Survey on 3-D simulations of earthquake ground motions in sedimentary basins. The ultimate goal of this research is to predict...
Using Environmental Tracers to Estimate Recharge Through an Arid Basin
Multiple tracer techniques were used to estimate recharge rates through unsaturated alluvium beneath the Greater Confinement Disposal site, a waste disposal site located in Frenchman Flat,...
Basin Scale Management of Surface and Ground Water
An important element in the economic development of many regions of the Great Plains is the availability of reliable water supply. The primary supply has tended towards developing groundwater...
Natural, Cultural, & Environmental Resource Values Influencing Colorado River Basin Management
The Colorado River Basin supplies water to the seven western states of Wyoming, Colorado, Utah, Arizona, New Mexico, Nevada, and California, and to Mexico. Originally the Colorado River...
Development of Bioretention Practices for Stormwater Management
This paper introduces the concept of bioretention as an innovative stormwater quality management practice. Bioretention is a method to treat the first flush of runoff using a combination...
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...
