Aids for the Hazard Classification of Small Dams
The last few years have seen a large growth in the tools available to the engineer to better determine the risk of failure in earth dams. One of the models developed is the National Weather...
Parking Lot Drainage Design: Gainesville, Florida
The construction of a 10-acre (4. 05 ha) parking facility (1,000-car capacity) at the University of Florida during 1984 presented the potential for increasing downstream flooding and for...
Imbrication of Tabular Boulders
Analysis of moments on tabular boulders projecting into a uniform stream indicates that a tabular boulder dipping downstream is unstable and can be overturned by velocities expected during...
Preliminary Engineering Design of an Artificial Tidal Lagoon System in Kuwait
A coastal resort project was planned for a 30 hectare site along the Arabian Gulf approximately 69 km south of Kuwait City at Dubaiyeh. The master plan, originally developed by Kuwait...
Management of Water Distribution System Components
The purpose of this study is to 1) analyze main break failures and 2) incorporate other drinking water distribution system components into a data base management structure for reliability...
Scour Downstream of High Level Emergency Spillways
The Corps of Engineers has numerous high level emergency spillways (HLES) including some that have the potential for excessive scour downstream during certain flow events. 'Excessive...
A Semianalytical Method for Solving Unsteady Flow Equations
This paper proposes a method that uses conjunctively the Laplace transform for continuous time and finite element for spatial discretization to solve unsteady flow equations. Laplace transforms...
Developing a User Friendly System for Water Distribution Management Applications
A hydraulic computer model of a water distribution system that can be updated with current billing (customer meter readings) information automatically. The model was calibrated with field...
Alternative Methods for Representing Sinkholes in Three-Dimensional Ground Water Flow Models
Two methods of representing the sinkholes in central Florida were investigated with a three-dimensional finite element model recently developed by Camp Dresser & McKee Inc. Both...
Ground Water Flow Simulation in a Small Drainage Basin
This paper describes the development and use of a numerical simulation approach for predicting ground water flow in a small drainage basin in southern California. The purpose of the modeling...
Two-Dimensional Groundwater Transport Subgrids in a 3-D Flow Model
The USGS Modular 3-D Finite Difference Ground-Water Flow Model by McDonald and Harbaugh (MODULAR) simulates ground-water flow in three dimensions by breaking the modeled region into several...
Methods for Specification and Verification of Hydraulic Design in a Turnkey Construction Contract
The project site is at the Hannibal Locks and Dam at New Martinsville, West Virginia. The existing project, a Corps of Engineers' (Corps) facility built in the 60's...
Development of a Monitoring Program and Vegetative Restoration Project in a Mississippi River Bendway
The Dry Bayou-Thompson Bend area is located on the right descending bank of the Mississippi River between river miles 4. 5 (7. 2 kilometers) and 30. 0 (48. 3 kilometers) above the confluence...
A Large-Scale Groundwater Transport and Dispersion Test: The First 1000 Days
TVA is conducting a large-scale field experiment to quantify the groundwater transport and dispersion of leachates from solid disposal facilities. This project is an integral part of the...
Contaminant Transport from an Array of Sources
The authors show analytic solutions to the problem of contaminant dispersion from an array of point sources in a waste disposal site. These solutions are for waste sources in a fluid-saturated...
Diversion Structure for Peak Flow Reduction
The flood control requirements of a planned development in the City of Orange, California were such that the peak discharges ranging from an annual flood up to 25-year return period be...
Lessons from the Failure of a Needle Valve
In 1984 a manually operated, hydraulically actuated 66-inch needle valve ruptured due to water hammer. The circumstances that caused the failure were reconstructed through extensive analysis...
Crop Production Models in Water Management
A weather generating model called WMAKER is introduced. The model generates daily climatic data based on the mean monthly values of temperature, precipitation, number of rainy days and...
Choices Between Micro and Mainframe Computers
The explosion of microcomputers (PCs) has shifted a great amount of engineering computing from mainframes to micros. It has also shifted a lot of programming from FORTRAN to BASIC. This...
Delivery System Management Via Dynamic Programming
Management of irrigation water delivery systems may involve allocating limited water supplies over both time and space under uncertain future demands. The physical delivery systems are...
