Structural Materials
This volume of Structural Materials contains papers from 12 sessions of the 7th Structures Congress held in San Francisco on May 1-5, 1989. The sessions cover a very broad range of topics...
A Parallel Partitioning Method for Large-Scale Circuit Simulation
In this paper, we discuss a partitioning method for large-scale circuit in parallel computer simulation. The partitioning method maps the sparse and irregular circuit equations to a special...
Computer Aided Design of Monolithic Integrated Circuits
An algorithm has been developed to relocate the sites of electrical components and integrated circuits. The process simulates site location changes in order that path lengths of conductors...
Local Area Network Communications Testing
This paper presents the philosophy developed for benchmark communications testing in networks typical of CAD/CAM environments. Implementation of the test philosophy in a connectionless...
Expert Systems for Assessment of Radon Gas
This paper covers a brief discussion of enviro-geotechnical aspects of radioactive toxic radon gas. Basic information required for assessment and controlling this gas is summarized and...
Continuous Sampling of Nonpoint Source Pollution
Sediment, nutrient, and other pollutant loads from storm water runoff in a small Texas watershed have been estimated using an initial strategy of periodic grab sampling and a revised strategy...
An Expert System for Groundwater Management with Applications to Collier County, FL
This paper describes techniques used in frequency analysis, time series model building, forecasting, up-dating, and mapping. Domain knowledge of experts is transferred into the system...
The Water Erosion Prediction Project: Model Overview
A new generation of water erosion prediction technology is being developed by the USDA Water Erosion Prediction Project (WEPP). The WEPP models are a new erosion prediction technology...
Parameter Identifiability in Conceptual Rainfall?Runoff Models
Computers have played a major role in the evolution of hydrologic rainfall-runoff models. Besides providing the computational power required for the simulation of the complex interacting...
TVA Weekly Scheduling Model Application Experience
Development of TVA's Weekly Scheduling Model was completed in 1980. Eight years of experience covering a wide variety of applications has now been accumulated. Since the basic...
Total Sediment Transport and Its Physical and Mathematical Modeling
Some main results in the field of sediment transport theories obtained by the author are presented. Based on these theories, the methods of physical and mathematical modeling for total...
Quasi-3D and Fully 3-D Modelling of Suspended Sediment Transport
The influence of different velocity and eddy viscosity fields on the computation of suspended sediment concentration and sediment transport rates, is presented here. Two different mathematical...
Numerical Modeling of Suspended Sediment Transport
Validity domain of hypothesis of depth integration has been approached by comparison of results of depth integrated model with complete vertical models. Use of shape functions to represent...
Advances in Computational Mobile-Bed Hydraulics
A new conceptual approach to one-dimensional mobile-bed simulation is briefly described, along with two demonstrative examples. The approach is based on fully coupled solution of the unsteady...
The Formation of Meandering and Braided Channels
Flow in alluvial channels implies flow past boundaries that form and deform under the action of the flow. Interaction between the flow and the mobile boundaries produces channel patterns...
Bed Waves Generated by Internal Waves in Alluvial Channels
The flow in an alluvial channel is conceived as a stratified flow both with respect to the velocity- and density-distribution. In such flows internal waves may occur which influence the...
On the Numerical Simulation of Suspended Sediment Transport in Estuaries
Estuarine fine sediment transport is governed by a wide range of hydrological, chemical and biological parameters including baroclinic circulation, tidal pumping, resuspension, deposition,...
Modelling Changes in Coastal Morphology
A description is given of a newly-developed coastal sediment transport model. Features of the model are the inclusion of cross-shore transport and non-potential suspended load, the latter...
Reliability of Bank Protection Works Subject to Erosion
Sediment movement and changes of bed levels in natural rivers are non-stationary processes. The design of protection works for structures against erosion should account for the time dependency...
Corps of Engineers' Mississippi River Sediment Studies
In conjunction with the 1838 U.S. Army Corps of Engineers hydrographic survey of the Mississippi River, CPT A. Talcott collected sediment samples in the passes 'to determine...
