Calibration of a Movable Bed River Model
This paper discusses the calibration procedures used for a model study of three miles (5km) of the Arkansas River. A hydro-power station will be added to an existing Corps of Engineers...

Bed Topography and Sorting in Alluvial Channel Bends
A quasi-three-dimensional model has been developed for the purpose of calculating the velocity distribution, the bed topography and sediment sorting along channel bends. The depth-averaged...

A Computer Model for Gravel Pit Headcut Simulation
Sand and gravel mining activities have led to numerous problems in river management. A review of many complaints on sand and gravel mining indicates that the major concern is structural...

Infiltration of Water to the Ground in a Flood-Control Reservoir with Seepage
As storm water management in urban area with increasing amount of runoff, flood-control reservoir with the bed having large permeability to enrich the groundwater is considered. A dynamical...

Reservoir Sedimentation Mathematical Modeling
The main objective for this paper is to show how one can predict the sediment movement, and estimate the volume of the deposited sediments, which is considered as one of the factor affecting...

Water Resources Planning and Management
The proceedings of the 16th annual Water Resources Planning and Management Conference, which was held on May 22-24, Sacramento, CA, consists of four page extended abstracts for about 200...

Ports '89
This is a collection of the technical papers presented at the triennial Ports '89 Conference held in Boston, Massachusetts in May 1989. Authors, although predominantly from...

Boundary Element Methods in Structural Analysis
Tutorial and state-of-art aspects of the Boundary Element Method (BEM) are combined with applications in structural analysis in order to provide information about the advantages of this...

Electricity From Air
After a decade of research and dozens of feasibility studies at sites around the country, the first Compressed Air Energy Storage (CAES) plant in the U.S. is under construction at McIntosh,...

Breakwater Choices
Most of the maritime breakwaters built throughout the world are of the rubble mount type, with a protective armor constructed of artificial blocks. Despite the multitude of different shapes...

Bullwinkle
The 1989 Outstanding Civil Engineering Achievement is an offshore oil production platform named Bullwinkle, a structure in the Gulf of Mexico that is taller than the Sears Tower, shaped...

Agriculture and Groundwater Quality
Nitrates and pesticides used in agriculture cause groundwater degradation. Agricultural practices in the U.S. will have to be changed to alleviate the health effects of these chemicals....

Analysis of Local Scouring
An understanding of local scouring is very important for the safety and integrity of hydraulic structures. The location, shape, and magnitude of the scour hole is a function of dynamic...

Stochastic Modeling and Generation of Droughts
Stochastic simulation was used for deriving drought properties of the Poudre River, Colorado and the Red River, North Dakota. The autoregressive moving average (ARMA) model and a threshold...

Predicting Human Instability in Flood Flows
The delineation of high flood hazard zones within a flood plain is usually independent of the parameters that constitute a life threatening situation. In order to define human instability...

Boundary Conditions of Tidal Model at River Mouth
A small grid is required to schematize irregular shape of shoreline in the vicinity of river mouth which limits the modeling area to be small. Tidal records along the boundary show no...

Application of Hydraulic and Sediment Transport Principles in the Design of Tidal Exchange Structures
This paper presents a procedure for the analysis and design of tidal exchange structures, such as tidal gates and training dikes. In lieu of over generalized theories or complicated modeling...

Sorting of Mixed Sand on a Two-Dimensional Beach
A numerical method is developed to predict temporal variations of the sea bed topography and the bed-material composition. The predicted results are compared with the measurements in a...

Comparison of DAMBRK With DWOPER for Computing Water Surface Elevations at Stream Junctions
The National Weather Service computer programs DWOPER (Operational Dynamic Wave Model) and DAMBRK (Dam-break) are one-dimensional models using an implicit finite difference method of solution...

Partnership in Environmental Design for Brush Creek Flood Control
Brush Creek drains a highly urbanized area in metropolitan Kansas City. A large physical model was used to develop a channel modification design for flood control. The Parks and Recreation...
