Modeling of a Low Head Hydroelectric Project
In order to shorten the time to develop a hydroelectric project at the Corps of Engineers Hannibal Lock and Dam on the Ohio River for the City of New Martinsville, West Virginia, a turnkey...
Hydrologic Forecasting in the National Weather Service
A description of hydrologic forecasting procedures of the National Weather Service (NWS) is presented. Also included is a description of various hydrologic products produced by the NWS...
The Effects of Sediment Transportation Changes on Aquatic Habitat
Sediments are a natural part of the riverine and estuarine environment. However, if the sediment load changes or bed sediment type occur, direct and sometimes detrimental and sometimes...
Sedimentation Problems of the Illinois River Valley
Natural and manmade factors have drastically changed the character of the river and resulted in the accelerated deposition of sediments all along the entire river valley. The Illinois...
Fine Contaminated Sediment Erosion/Deposition in the Buffalo River, New York
This paper documents part of a project which sought to characterize sediment transport in the Buffalo River as a contribution toward planning for dredging or in-place containment of the...
Estimation of Uplift Pressure in Cracks in Concrete Gravity Dams
This paper presents an analytical solution to predict uplift pressures in cracks in concrete gravity dams. It is shown that drainage systems are effective in reducing such pressures....
Field Investigation in an Estuary: A Case Study of Cooper River/Charleston Harbor
In 1942, the flow of the Cooper/Ashley/Wando (South Carolina) River complex was altered by a flow diversion project. Subsequently, Charleston Harbor suffered a dramatic increase in maintenance...
Three-Dimensional Modeling of a Stratified Estuary
Development around Choctawhatchee Bay, and reduced productivity, loss of seagrass beds, and higher salinities, prompted the Northwest Florida Water Management District to conduct an investigation...
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 Survey of Lake Powell
The 1986 Lake Powell Sediment Survey documented the present storage-elevation relationship and loss of storage from sediment accumulation since the reservoir began filling. From the calculated...
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...
Expert System for Mixing Zone Analysis of Aqueous Discharges (CORMIX1): Further Developments
Two recent publications have reported the development of the Cornell Mixing Zone Expert System (CORMIX) for the analysis, prediction and design of aqueous toxic or conventional pollutant...
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....
Task Committee Report on Reliability Analysis of Water Distribution Systems
The results of the ASCE Hydraulics Division Task Committee on Reliability Analysis of Water Distribution Systems are summarized in a very comprehensive report entitled Reliability Analysis...
New Methodology for Determining the Optimal Rehabilitation and Replacement of Water Distribution System Components
A methodology is presented for the determination of the optimal timing for the rehabilitation/replacement of water distribution system components in order to minimize costs. In this model...
