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...

Applications of the Singular Point Method to Hydraulic Analysis of Spillways
A computer-oriented procedure is described to develop rating tables for side channel spillways. The procedure includes three sets of computations which have to be performed iteratively...

Computation of Supercritical Flow in Open Channels
The use of two explicit, shock-capturing, finite-difference schemes, Lax and MacCormack, for the solution of two-dimensional shallow-water equations in steady, supercritical flow is investigated....

Lower Mississippi River Salt Intrusion Modeling
A laterally averaged numerical model called LAEM has been employed for both a 40- and 55-ft channel. In addition, LAEM has been applied with an increased height of the natural river crossing...

Nontidal Exchange Processes at the Chesapeake Bay Entrance
Magnitudes of gravitational and meteorologically-driven exchange at the entrance to the Chesapeake Bay are compared using current measurements, numerical model runs and subtidal volume...

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...

Low Head Dam Safety Studied with Hydraulic Models
Use of physical models to study the hydraulic jump or submerged roller action created as water overflows low head dams provides an opportunity to develop design criteria for various structure...

The Development of Test Cases for Hydrodynamic and Transport Models
This paper reviews the test cases employed by several investigators in the development of two- and three-dimensional finite difference and finite element hydrodynamic and transport models....

Modeling Materials for Protecting Earth Weirs
This paper reports laboratory experiments on various materials used to protect earth weirs. Dumped rock, gabion mattresses, and shaped blocks on a gravel layer were subjected to high velocity...

Design of Overtopping Protection for Small Dams
Many existing small embankment dams in the United States cannot safely pass current design floods without overtopping. In the past several years, embankment overtopping protection has...

Advanced Concept for Generation of Waves in Hydraulic Models
This paper describes a new wavemaker for the generation of naturally occurring waves in physical models of coastal areas. Recent research incorporating directional aspects of monochromatic,...

Hydraulic Model Investigation of the North Diversion Structure, Albuquerque, New Mexico
The North Diversion Structure diverts storm runoff around Albuquerque, New Mexico. Observed flow conditions have caused concern about the capacity of the structure and the safety of a...

Uncertainty in Models for Environmental Management
In recent years, computer models have become increasingly popular as tools to aid the decision-maker in balancing complex, interacting factors in environmental management and pollution...

Input Programs for Engineering Applications
This paper discusses several input program types and the data structures associated with them. Two input programs were designed for KYPIPEF to demonstrate the use of files of records and...

Accuracy of Computed Water Surface Profiles
Stream cross-sectional geometry obtained from aerial surveys (aerial spot elevations and topographic maps) that conform to mapping industry standards are more accurate than is often recognized....

Effects of Land Subsidence on Flood Profiles
In this study, the effects of land subsidence on water-surface elevation and depth profiles during flood conditions were investigated for a large, hypothetical, slope-controlled stream....

Comparison of Some River Discharge Calculation Methods
To measure the discharge of a river, it is necessary to develop a stage-discharge curve based on water velocity at various cross sections of the river. This is the method which is used...

Numerical Model Analysis of Sedimentation Problems at Lock and Dam 1, Red River Waterway
This paper addresses the numerical modeling techniques used to identify the conditions and parameters affecting sediment deposition at Lock and Dam 1. Two-dimensional finite element models...

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...
