Physical Modeling of Contracted Flow
Experiments on steady flow over uniform grass roughness through centered single-opening contractions were conducted in the Flood Plain Simulation Facility at the U. S. Geological Survey's...

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...

Penetrative Convection in Mixed Layer Models
While surface heat transfer is important in lakes and reservoirs, solar radiation, which penetrates the water surface and is absorbed in the water column, also exists. In this work, a...

The NOS Experience in Real-Time Measurements of Tidal Currents
NOAA'S National Ocean Service (NOS) uses the term RADS, Remote Acoustic Doppler Sensing, for a new class of oceanographic instruments that uses acoustic backscatter to probe...

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...

Rehabilitation Measures?Wanaque Reservoir System
The rehabilitation of Pompton Lake Dam and the dams of the Wanaque Reservoir System has provided the North Jersey District Water Supply Commission with a safe, dependable source of water...

Techniques for Measuring Flow and Sediment Parameters Near the Bed in Estuaries
The collection of accurate and meaningful field data is often the key to successful description and prediction of natural processes. The U. S. Army Engineer Waterways Experiment Station...

Nonhomogeneous Terms in the Unsteady Flow Equations: Modeling Aspects
A study is in progress to identify the relative significance, effects, and benefits attributable to the use of one-dimensional, unsteady, open-channel, flow-simulation models employing...

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...

GLVHT Model Verification using Field Data
The Generalized, Longitudinal-Vertical Hydrodynamic and Transport model (GLVHT) as developed for the U. S. Army Corps of Engineers Waterways Experiment Station and described in Buchak...

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...
