Storage Projection for Reservoir Systems
Two methods are studied for determining the probability distribution of future levels of storage in a reservoir system: transient analysis and Gould's probability matrix method....

Risk-Cost Analysis and Spillway Design
The NRC's recent report on dam safety proposes risk cost analysis to help select among alternative spillway modifications for existing dams. This paper examines the sensitivity...

The SRI Technique for Flood Frequency Analysis
This paper presents a technique for flood flow frequency analysis called the Storm Response Index (SRI), and a case study using the technique. The SRI method is based on the development...

A Physical-Chemical Interpretation of Mean and Extreme Values in Acid Precipitation
A physical-chemical model is used for the interpretation of mean and extreme concentrations in acid precipitation. Chemical concentration frequency distributions tend to be skewed, as...

Coastal Erosion Management in Australia and the U.S.
Current knowledge and management policies in both Australia and the U. S. favor non-structural over structural responses to coastal erosion problems wherever possible. The trend towards...

Construction-Induced Dynamic Pressure and Corresponding Impact Factors for Pipelines
The Bureau of Reclamation, U. S. Department of the Interior, conducted a study which measured pressure exerted by construction scrapers on a rigid, buried, instrumented concrete slab....

Dynamic Responses of Buried Pipelines
The dynamic responses of the pipelines are analyzed by the continuous mass matrix method by considering the soil as a bounded plane in which the pipeline is placed. The friction between...

Stormwater Routing for Small Sites
Traditional hydrologic analyses and detention design procedures are too time consuming and costly to be warranted for small projects. This paper discusses a direct solution for sizing...

Estimating Peak Flow Reduction in Small Reservoirs
A microcomputer program is used to provide a simple and rapid estimate of the peak outflow from such reservoirs. Peak flow values, determined by flood frequency analysis or regional flood...

Explicit Hydraulic Modeling of Sedimentation Transients in Alluvial Channels
An explicit finite difference numerical scheme is used in this study to model sediment transients in alluvial channels. The governing equations are momentum equation and continuity equation...

Microcomputer Graphics Flood Stationarity Test
Only records that correspond with present river conditions should be used with flood frequency analysis when forecasting. A microcomputer test is discussed which aids in selecting appropriate...

Constitutive Theories for Solids with Defective Microstructure
The nonlinear mechanical response of solids is a macroscopic manifestation of the irreversible changes in its microstructure. The most common modes of the irreversible microstructural...

Impact on Test by Various Multiaxis Excitation
The purpose of this paper is to provide input guidelines in evaluating various types of multiaxis excitation on fragility level testing of electronic devices. There are many variables...

Structural Steel Details: Comments on Divided Responsibility
Five readers responded to an article on responsibility for structural steel details published inCivil Engineering�ASCE, Oct. 1983. Most agree...

Dynamic Response Correlation of Cylindrical Tanks
The May 1983 Coalinga Earthquake provided an opportunity to correlate earthquake performance of cylindrical liquid storage tanks with behavior observed in laboratory shaking table experiments....

Update on Impact Effects in Nuclear Plants Part I?Overview and Need for Integrated Approach
In this paper, an ASCE working group on impact effects in nuclear plants updates the review of this technology contained in a five-year-old ASCE report. In Part I, an overview is given...

Nonlinear Analysis of Reactor Vessel & Core Supports Subjected to Accidental Impact Loads
Nonlinear dynamic analyses of the reactor vessel, its support systems, the core and the core supports were performed to evaluate the consequences of such drops. Damage was defined in terms...

Sensitivity of Peak Dynamic Responses to Input Factors
Responses have been calculated for the Zion Unit 1 plant, using the SSMRP computer code SMACS, as part of the seismic probabilistic risk assessment performed by the Seismic Safety Margins...

Coupled Vertical-Rocking Response of Base-Isolated Structures
A base-isolated building can have a small horizontal eccentricity between the center of mass of the superstructure and the center of rigidity of the supporting bearings. The structure...

State-of-the-Art of Development of Floor Spectra
Floor spectra are used as seismic inputs for the design and qualification of subsystems and equipment. Until very recently, the time history analyses with single acceleration time history...
