Settling Basin Model for the Personal Computer
The SETSIZE program, models sediment deposition in a settling basin. The program can be applied to determine the length of time until dredging or cleaning is necessary or solve for an...
Soil Erosion and Sediment Transport Modeling on Small Tropical Watersheds
A fundamentally-based concept of a soil erosion and sediment transport model in a forest tropical area is presented. It will be incorporated to the ANSWERS model. The forest hydrology...
A Watershed Model of Sediment Transport?Load-I
A watershed sediment transport model has been formulated and optimized upon storm hydrographs and the associated sediment load data for several watersheds that have been urbanized and...
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...
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...
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...
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...
Scour Assessment at Bridges
Due to the key role that bridges play in the national transportation system, the Federal Highway Administration has developed a scour evaluation program. This program, issued in the form...
Local Scour at Bridge Abutments
Comparison of local scour depths at bridge abutments computed using different equations yields a large variation in predicted values. To consolidate the fragmented results of previous...
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...
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...
Hydraulic Mechanisms of Riverbank Erosion
Recent efforts are described to develop an improved understanding of bank failure due to piping in noncohesive layers in riverbanks. The efforts included field surveys and laboratory tests....
Geotechnical Aspects of River Bank Erosion
The principal geotechnical mechanisms of river bank failure are identified on the basis of extensive field investigations on many different river systems. The role of each factor depends...
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...
Peak Outflow From a Breached Embankment Dam
A relation for rapidly predicting the peak outflow rate from a breached embankment dam has been presented. The prediction equation is based on reliable data from 19 embankment dam failures...
Regional Flood Plain Management
A flood plain management plan for White Rock Creek in the Cities of Dallas and Plano, Texas was developed. New technologies such as three-dimensional topography, CADD, and remote sensing...
The Role of Vegetation in River Bank Erosion
The purpose of this paper is to describe briefly how streambank vegetation, both roots and shoots, modify the 'skin' or surface layer and how this in turn affects...
Improved Numerical Analysis of Steady Water Surface Profiles
As well as HEC-2 and similar models serve the profession, problems exist with their application. In general, inflexibility of use and inaccuracies around transitions between subcritical...
Determining River Stages with Consideration of Backwater Effects
In a recent hydraulic investigation on the Cache River basin, the stages of the Mississippi River at the Beechridge station were found to be necessary downstream boundary conditions for...
Analysis of Pumping Station and Force Main Networks
A computer program to simulate the performance of wastewater pumping station and force main networks is discussed. Results are presented which compare system performance for steady and...
