Effect of Conowingo Dam Releases on the Water Quality of the Lower Susquehanna River
A modeling study was performed to assess the effects of flow releases from Conowingo Dam on the water quality of Conowingo Pond and the Susquehanna River downstream of the dam. Reservoir...
Sediment Variability Mark Twain Lake, Missouri
This paper looks at the historical variability in suspended sediment loads in the Upper Salt River Basin above Mark Twain Lake, Missouri in an attempt to assess the magnitude of suspended...
Martins Fork Reservoir Sedimentation Study
The Martins Fork Reservoir is located on Martins Fork of the Cumberland River in Harlan County, Kentucky. The lake was impounded in December, 1978. Since closure, the lake has experienced...
Entropy as a Probability Concept in Energy-Gradient Distribution
The concept of entropy based on probability theory instead of thermodynamic principle has been applied to study the distribution of energy gradient along alluvial rivers. The formulas...
Longitudinal Dispersion in Rivers: A Dead Zone Model Solution
The longitudinal dispersion of tracer material in rivers is often analyzed based on the one-dimensional convective diffusion equation developed by G.I. Taylor. However, the persistent...
Silt Run Effectiveness in Withdrawing Sediment
An investigation was conducted during the silt runs on the North Platte River to determine the continued effectiveness of the runs in providing fine sediments to the canal systems downstream....
Utilization of Ground Penetrating Radar to Conduct Sediment Surveys of Frozen Reservoirs
The ground penetrating radar (GPR) system consisted of a control unit, antenna, recorder, a power supply on a sled towed by a snowmobile. A 120 Mhz antenna was utilized and gave excellent...
Sediment Flushing Experiences at Cherry Creek Dam
An overview of the U.S. Army Corps of Engineers, Omaha District's experiences in sediment flushing operations at Cherry Creek Reservoir near Denver, Colorado is presented....
An Error Analysis of the Dynamic Wave Model
The Dynamic Wave Operational Model (DWOPER) is used to forecast river stages on the Lower Columbia River. DWOPER was developed by the National Weather Service's Hydrologic...
Two-Dimensional River Modeling of Buckhorn Creek
A two-dimensional Finite Element Surface Water Modeling System (FESWMS-2DH) was used to simulate flow at a bridge crossing of a heavily vegetated flood plain where State Highway 130 crosses...
Waste Processing: Makes Good Energy
Materials separation in solid wastes streams will generate more BTU's at waste-to-energy facilities. The removal of noncombustibles like bottles, batteries and refrigerators...
Minipiles Mature in America
After being born more than 40 years ago in Europe, minipiles are maturing in the United States. Their distinctive feature is a relatively small diameter, rarely larger than 12 in. Constructing...
Out of the Mainstream
By treating only part of the wastewater stream, a biological/chemical phosphorus removal system also reduces chemical costs and sludge production. The system consists of two 60 ft dia...
Water-Quality Ponds ? Are They the Answer?
Water-quality 'wet' ponds have been proposed to treat storm water for the removal of phosphorous in streams tributary to Cherry Creek Reservoir, a major recreational...
Urban Runoff Management?An Industry Perspective An Opinion
Coors presently produces about 17 million barrels of beer per year from a single plant about 15 miles west of Denver. The company chose to keep the responbibility for the quality of its...
Bureau of Reclamation's High Plains States Ground Water Recharge Program
The Bureau of Reclamation is conducting a two-phase program to demonstrate the feasibility of recharging declining aquifers in the 17 western states. The U.S. Geological Survey (USGS),...
Tucson Recharge with Existing Potable Water System
In 1987, a study was undertaken to evaluate the potential for using the City of Tucson's existing potable water distribution system and production wells for recharge of treated...
Quality Changes of River Rhine and Meuse Water Upon Basin Recharge in the Netherlands' Coastal Dunes: 30 Years of Experience
A wide spectrum of quality changes of river Rhine and Meuse water is presented, on a global scale after pre-treatment, dune infiltration and post-treatment. Attention is focussed on the...
Augmenting Water Supply in the Phoenix Area Through Recharge of Surplus Central Arizona Project Water Into the Agua Fria Riverbed
This paper describes the efforts of several months activities in the initial stages of developing a 30,000 feet Demonstration Recharge Facility for surplus Colorado River water on the...
