Managing a Drought Through Advance Water Resources Planning: The Iowa Approach and Experience
It is important for states and local governments to devise and implement strategies for dealing with their water resource needs during a drought. This paper discusses the mechanisms that...
Determination of Optimal Capacity for Water Imports
Determination of the optimal size of water import facilities is inextricably related to the issue of establishing the optimal water price, and is made more difficult by the stochastic...
Mathematical Modeling of Water Balance in a Well Defined Pilot Area
This study developed a water balancing computer code, a type of book keeping method using a detailed version of the hydrologic balance equation. The purpose was to provide a method of...
Water Supply and Conservation in a Desert City
The city of Phoenix, a fast growing metropolitan area, set in the northern reaches of the Sonoran Desert, seems to have reached the limits of the western water frontier. Presently, Phoenix...
Optimal Operational Analysis of the Colorado-Big Thompson Project
The Northern Colorado Water Conservancy District is currently investigating the feasibility of constructing a major water storage project on the mainstem of the Poudre River for water...
Near Bed Sediment Concentration as Influenced by Turbulence
Suspended sediment concentration profiles are developed based on the conservation of mass and conservation of momentum equations of sediment laden flows. The resulting concentration profile...
1-D and 2-D Analysis of Flood Plain Encroachment
The paper reports on a study into the effects of a local encroachment in a broad regular flood plain. The results of a one-dimensional analysis were compared with the results of an equivalent...
Utilization of Expert Systems for the Operation of Reservoir Systems
This paper illustrates how knowledge-based expert systems can obtain, organize, document, store, and utilize valuable complex reservoir systems experience, obtained by experienced water...
Optimizing Joint Load Control for Hydroelectric Plants
This paper discusses a method to minimize water usage at a multi-turbine hydroelectric generating plant. At plants which do not spill water this optimization is directly converted to extra...
Efficiency Monitoring Yields Large Revenue Gains
This paper presents a Washington Water Power Company program to increase hydroelectric plant operations' efficiency. This increase is due to improved flow, head, and megawatt...
Waterpower Development: A Renewed Partnership
Efforts to meet the water supply and energy needs of the country in a changing economic, environmental, and technical environment create new opportunities for joint action by water and...
