Comparing Results of Wave Data from Two Recorders
In this paper two sets of wave measurements made in the same region using a pressure transducer and a wave rider bouy are compared. The same methods of analysis were applied to both the...
Enhancing Diked Wetlands in Coastal California
Significant areas of wetland in coastal California are diked off from full tidal action. These areas retain considerable value as wetland, and their management and enhancement present...
Numerical Modeling of the Coastal Current Regime at Yaquina Bay, Oregon
The application of a family of hydrodynamic numerical models for simulating tidal and wave-induced currents at Yaquina Bay, Oregon, is described. An overview of four numerical models is...

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...
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...
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...
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....
Cellular-Automata for Hydrodynamic Modeling
A two-dimensional fluid continuum system can be modeled using a discrete field of particles that interact according to simple deterministic rules. The methodology is called Cellular Automata....
Three-Dimensional Modeling of Estuarine Circulation and Contaminant Transport
The conjunctive use of optimal grid and the generalized 3-D hydrodynamic model allows accurate and efficient simulation of realistic estuarine circulation and transport problems. Sheng...
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...
Evaluting the General Well Function
The closest thing to a mathematical function that maps well discharge to drawdown has been Jacob's equation, caled the step-drawdown equation. However, this equation assumes the drawdown...
Analysis of Storm Event Suspended Sediment Data From Tennessee
In order to provide an understanding of transport patterns, historical suspended sediment data collected by TVA in the late 1930s were computerized and entered onto WATSTORE. Frequent...
Dimensional Analyses of Yellow River Sediment Data
A contemporaneous set of bed load and suspended load sediment transport data were analysed for three hydrologic stations on the Yellow River. There were a total of 82 bed load events,...
Low Head Hydropower Finite Element Analysis
Finite element analysis provides a means of predicting the flow conditions resulting from the operation of a proposed hydropower facility. The results of a finite element flow analysis...
Real Time Modeling to Meet Flow Requirements at a Fossil Steam Plant
A real time modeling system has been developed to schedule hydropower operations in order to comply with discharge permit requirements at a downstream fossil steam plant. The modeling...
Hydraulic Investigation of the Cache River Basin
