Operation of Hydropower Plants Considering Daily Streamflows
Operation of hydropower plants is a sequential decision process often modeled as a dynamic programming problem. Typically, such formulations consider monthly stages assuming that monthly...
Streamflow Gaging in a Remote Area Using Cellular Telephone Telemetry
A case study will be presented describing the utilization of cellular phone technology in a remote sensing situation. Because expected annual energy estimates are vital in planning small...
Ground-Water Recharge from Streamflow Data, NW Florida
Annual base flows of streams draining Okaloosa County and adjacent areas in northwest Florida were determined through hydrograph separation and correlation techniques for purposes of evaluating...
A New Method for Calculating a Mathematical Expression for Streamflow Recession
An empirical method has been devised to calculate the master recession curve, which is a mathematical expression for streamflow recession during times of negligible direct runoff. The...
Effects of Uranium Mining, Puerco River, New Mexico
Effluent from uranium-mine dewatering and acidic water released by a tailings-pond dike failure increased radionuclide activities in streamflow in the Puerco River in New Mexico and Arizona....
Geochemical Mass-Balance in a Small Forested Watershed in Southwestern Pennsylvania
An intensive hydrologic investigation of the North Fork Bens Creek Watershed on Laurel Hill in southwestern Pennsylvania was made during 1984-85. Precipitation was sampled weekly, and...
Discharge Forecast of Underground Tunnel System
An underground tunnel system can be discribed with linear system theory and its mathematical model can be made up according to its recharge and discharge conditions. But, because of so...
Effect of Nile River Flow on Performance of Shoubrah Power Plant Cooling System
Shoubrah El-Khimah Power Plant was built in 1982. Its peak capacity is 1200 MW, generated by four units, three of them having one cooling water intake. The cooling water pumps suffer from...
Incipient Motion Criteria Defining Safe Zones for Salmon Spawning Habitat
Approximately 70% of the City of Seattle's water supply is drawn from the Cedar River. Between 200,000 and 400,000 sockeye salmon spawn annually in this partially dewatered...
Influence of Wetlands on Streamflow in Illinois
Streamflow records from 30 gaging stations in Illinois were analyzed to assess the influence of wetlands on streamflow. The objective of this research was to determine if streamflow parameters...
Wetland Drainage and Streamflow Trends in Illinois
Long-term streamflow records from 30 gaging stations in Illinois were analyzed to assess the impact of wetland drainage on streamflow trends. The objective of the research was to determine...
One Power Plant, Two Job Sites
In response to the lingering questions about energy, officials from Vidalia, La initiated a plan in 1977 to build a hydroelectric plant at a site 90 mi northwest of Baton Rouge, where...
Using an Index Stream to Make Instream Flow Decisions
The paper discusses development of an Integrated Operating Plan (IOP) that uses an unregulated (natural) stream in the upper Cedar basin as an index of overall hydrologic status of the...
Estimating Lake Inflows for Storage by Linear Programming
The Lower Colorado River Authority (LCRA) recently completed a Water Management Plan for the lower Colorado River Basin in Texas. In developing the Plan, a daily river flow routing procedure,...
Conflict Resolution, Reallocation and Management of Lake Texoma Resources
From its inception, Lake Texoma has created conflicts among users of its natural resources, including hydropower, water supply, flood control, and recreational users. Many attempts have...
Some Hydrological Impacts of Climate Change for the Delaware River Basin
To gain insight into possible impacts of climate change on water availability in the Delaware River, two models are linked. The first model is a monthly water balance model that converts...
Instream Habitat Considering Hydro-Peaking
Hydroelectric projects with storage have the characteristic of being able to generate electricity with short notice and to stop generating electricity with equally short notice. This peaking...
Streamflow Prediction and Allocation Model in Texas
The State of Texas' Water Rights Adjudication Act of 1967 provided for the creation of regional watermasters to divide the water of state streams in accordance with the adjudicated...
Application of a Water Budget for Instream Flows
A portion of a water supply reservoir can be dedicated to supplying instream flows. This subreservoir is operated to provide instream fish habitat below the reservoir when releases to...
Water Reallocation of the Carson River
The federal courts have not been able to allocate the waters of the Carson or Truckee Rivers in such a manner as to satisfy all the users. As a result, there have been a number of suits...
