The Shaft Excavation Effect Experiment
The Shaft Excavation Effect (SEE) experiment has been carried out by Power Reactor and Nuclear Fuel Development Corporation (PNC). Corresponding to this experiment, an evaluation system...

Three-Dimensional Groundwater Flow Modelling for a Potential Repository Site
In Finland site investigations are carried out at five places in order to find a suitable site in the Finnish bedrock for a repository for spent nuclear fuel. The aim is to model the bedrock...

General Circulation Models: Applications for Nuclear Waste Repositories
Numerical models have long been used to relate causal and response functions in the natural environment. Some 20 years ago, one-dimensional, multi-causal models of earth temperature evolved,...

Three-Dimensional Thermal Analysis for Temperature Distribution in Geological Formation
A three-dimensional conduction heat transfer program has been developed for use on microcomputer for thermal analysis of a conductive medium subject to, finite length heat sources. The...

Integrated Structural Engineering Solution for Design, Drafting and Analysis
Computervision Corporation is a leading CAD/CAM/CAE vendor that offers a complete integrated structural solution to customers. This structural solution allows customers to manage intricate...

Integrated Structural Design Software in the IBM Architecture & Engineering Series
The Architecture and Engineering Series (AES) software by IBM is a high function, fully integrated design, drafting, and information system. The system provides three dimensional geometry...

Integration of CAD and Structural Engineering for Building Design
Many design/build contractors have publicized successes using three-dimensional (3D) computer-aided-design (CAD) models. Structural engineers contribute equipment support structures as...

COMBAT.PC; a New Windows-Based Tool for Three-Dimensional Dynamic Analysis of Multi-storied Building Structures
By some accounts, analytical capability without the power of visualization is little productive; visualization is the tool that will turn computational power into practical results. COMBAT.PC...

Discrete Optimal Design of 3D Frameworks
The paper describes a discrete optimization method for the least-weight design of three-dimensional (3D) steel building frameworks. The method involves the coordinated application of structural...

Low Stream Flow Frequency Analysis with Ordinary and Tobit Regression
In order to estimate the low-flow quantiles at ungaged sites, it is necessary to estimate low-flow quantiles at gaged sites. Two linear regression methods, denoted NR and NE, are compared...

Application of Kalman Filtering to Groundwater Flow in Finite Heterogeneous Aquifers
A stochastically based methodology using Kalman filtering is presented for the optimal estimation of hydraulic properties in finite heterogeneous aquifers. This is achieved by applying...

Downstream Danger from Sudden Discharges of Water
The sudden, unexpected release of water by hydropower facilities poses a threat to fishermen and boaters immediately downstream. The characteristics of the danger can be identified, however,...

A Bivariate Stochastic Reservoir Model
A bivariate distribution of peak flows and volumes is derived taking into account their correlation structure. This distribution is then used to derive reservoir operation curves which...

Field Measurement of Surface Flows in Shallow Estuaries
This paper summarizes our first-year results of an ongoing multi-discipline project, which examines the physical processes of wetlands erosion and loss in coastal Louisiana. Our task is...

Flushing Characteristics for Harbor Planning
A two-dimensional hydrodynamics model was used to understand the circulation and transport patterns in Keelung Harbor, Taiwan. The calculated hydrodynamics information was used to determine...

Central Valley Groundwater and Surface Water Model: A Conjunctive Use Planning Tool
A three dimensional finite element groundwater simulation model is integrated with a surface water simulation model to evaluate the conjunctive use feasibility for a specific area. The...

CSO Pollution Abatement Project Performance
The City of Trenton, NJ combined sewer overflow (CSO) pollution abatement project has been in operation for more than four years. Daily records include composite BOD₅...

An Expert System for the Planning and Design of Flood Control Channels
The planning and design of flood control channels often calls for the evaluation of a unique set of physical conditions which do not lend themselves to standard designs. Consequently,...

A Comparison of Accuracies of Steady Water Surface Profiles
The author compares the effect of varying boundary conditions and cross sectional spacing on one dimensional steady water surface profiles. Six streams are modeled using both the 10 and...

Unification in Estimation of Confidence Intervals
One area of future development needs in technology pertaining to surface runoff hydrology is the unification of techniques used by govermental agencies in the estimation of surface runoff...
