The Briny Deep Comes Ashore
Amusement park attractions are not all fun and games. More than 10 years of planning by dozens of firms went into the Living Seas Pavilion at Walt Disney's Epcot Center. The...
Structural Systems for Multispan Cable Suspended Bridges
Multispan cable suspended bridges, i. e. , cable-stayed or suspension bridges with a large number of consecutive main spans of equal size, must be carefully designed to become economical...
Development of a Double Tee Structural System for Highway Bridges
The fully precast, prestressed double tee beams are tied together by transverse post-tensioning through simple grout filled V-joints. The system provides for complete transversal continuity...
Design Rainfall for Pennsylvania
The most commonly used source of rainfall estimates is the U. S. Weather Bureau Technical Paper 40. A more detailed study of Pennsylvania storms was conducted in 1970 under the sponsorship...
Water Supply Demand Forecast
In this study, estimates of location, quantity and timing of water demands have been investigated for determination of the adequacy of an existing water supply system, the need for additional...
The Northwest Watershed Research Center, 1959-86
Hydrologic research has been conducted on the Reynolds Creek Experimental Watershed by the Agricultural Research Service for nearly 27 years. Some noteworthy instrumentation, developed...
ENDOW, An Expert System for Screening Environmental Features for Stream Alternations
This paper discusses development of an expert system for Environmental Design of Waterways Projects (ENDOW) by stream alteration specialists who were novices in artificial intelligence....
Expert System for Mixing Zone Analysis of Toxic and Conventional Discharges
The Cornell Mixing Zone Expert System (CORMIX) is a series of software subsystems for the analysis, prediction and design of aqueous toxic or conventional pollutant discharges into watercourses...
Interagency Standards for Automated Local Flood Warning Systems
The need exists for establishing guidelines and standards for aspects of local flood warning systems. The demand for increased flood warning systems is expected to increase due to the...
Feasibility Studies of Flood Warning-Response Plans
Local flood warning-emergency preparedness plans consist of hardware, technical activities, and formal and informal inter- and intra-organizational arrangements and commitments to performance...
Optimal Flood Warning and Preparedness Plans
This paper includes a framework for selecting the optimal investment in warning and preparedness activity. The primary factors which might influence the magnitude of cost and damage are...
Emerson, Iowa Flood Warning System
A flood warning system was installed in 1985 by the Corps of Engineers at Emerson, Iowa as part of Emerson, Iowa Flood Control Project on Indian Creek. The warning system consists of two...
The Santa Ana River Flood Forecasting System
A real-time flood forecasting and reservoir operations simulation system has been developed for the Santa Ana River Basin, located in southern California. The system consists of generalized...
Underground Drainage of Urban Runoff from Natural Depressions
A unique subsurface system was designed and implemented for draining such a natural depression in the City of West Lake Hills, Texas. This subsurface drainage system uses a part of the...
Heppner, Oregon Flood Warning System: An Interagency Cooperative Effort
The flood warning system is a network of event-actuated precipitation and river level gages in two flash flood prone drainage basins of 44 and 6. 8 square mile areas. These basins enter...
Minimizing the Impact of Salinity Intrusion Due to Sea Level Rise
A rise in sea level will cause saline water to intrude up estuaries including those adjacent to aquifers with major pumping centers. During a drought a significant amount of saline estuary...
Transport Model for Aquifer Reclamation Management
A contaminant transport model which is specifically designed for management applications is developed. A key feature is the transient velocity field needed in the solution of the advection-dispersion...
Modeling Coal Pile Leachate - A Case Study
Ground water transport of coal leachate from an existing unlined coal storage pile was modeled using the USGS 'Computer Model of Two-Dimensional Solute Transport and Dispersion...
A Riverflow-Water Quality Control Model
In order to implement how regulated riverflow (control variable) impacts the salinity (output variable) under a tidal dynamic environment, a multiple input control system is developed....
Deriving Streamflow Distribution Probabilities
Streamflow distribution probabilities are often involved in the stochastic analysis of water resources systems. Limited by data availability, certain probability terms can hardly be abstracted...
