Assessment of Derived Flood Frequency Distributions
Derived flood frequency distributions based on the geomorphologic IUH are evaluated in this work. Two existing approaches, the methods of Hebson and Wood (1982) and Diaz-Granados et al....

A Frequency Surface for Rainfall Intensity and Duration
A technique for developing rainfall intensity-duration-frequency surface is presented. With the aid of the Box-Cox power transformation raw data is transformed into a jointly near normally...

Effects of Liquefaction on Lateral Pile Responses
The potential significance of the impact of liquefaction on the dynamic response of pile foundations has been studied through a numerical study. Results of this study demonstrated that...

Flexible Membrane Wave Barrier
A linear analytical model is developed for the dynamic response of a flexible membrane wave barrier. The wave barrier consists of a thin flexible membrane suspended in the water column...

Response Statistics of Tension Leg Platforms Under Wind Loads
This paper presents the direct integration method and Kac-Siegert technique to solve the first four cumulants in the general quadratic systems, and proposes the splitting technique to...

Stability of Cable-Stayed Brides
This chapter deals only with stability under static loadings. For aerodynamic stabilities and stability of structure under seismic loading, see the appropriate chapters. Both the towers...

Evaluation of Intensity-Duration-Frequency Curves by Point Precipitation Models
In this work an alternative approach to estimate the Intensity-Duration-Frequency curves is used. This approach which uses point precipitation models recently proposed in the literature...

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...

Unique Water Quality Aspects of Lake Pontchartrain
Natural factors causing changes in Lake Pontchartrain, can be grouped into the following: subsidence and wetland loss due to the deterioration of the St. Bernard Delta, natural variations...

Analysis of 1989 Floods in Harris County, Texas
On May 17 and 18, 1989, a severe thunderstorm stalled over Harris County, Texas, producing over fourteen inches of rain in a twenty-one hour period. Slightly more than one month later...

Summary of the National ASCE Task Committee on Costs-Benefits of Various Design Frequencies for Urban Drainage Systems and Flood Control
The National ASCE Task Committee on: 'COSTS-BENEFITS OF VARIOUS DESIGN FREQUENCIES FOR URBAN DRAINAGE SYSTEMS AND FLOOD CONTROL' recommends that public officials...

Effect of Storm Distribution on Watershed Stormwater Management
This paper presents a case study illustrating the effect of the selection of rainfall distribution pattern upon the ability of a calibrated rainfall-runoff simulation model to replicate...

Computer Modeling as a Tool for Selecting Appropriate Air Valves for Pipeline Surge Protection
Waterhammer in water or wastewater pipelines is caused by events such as a pump power failure and can have potentially damaging effects on the pipeline or pipeline hardware. In particular,...

Structural Response Statistics by Boundary Elements
In this paper a boundary element method for problems of random vibration of continuous structures is presented. The method reduces the effect of the mesh size on the accuracy of the results....

Explicit Integration Schemes in Structural Dynamics
Based on the recursive explicit form of Newmark ?-? method developed by Zienkiewicz for displacements, similar recursive expressions for velocities and accelerations are developed. General...

Perplexing Issues in Concrete Softening
We explore some of the proposed techniques for modeling 'softening' via the constitutive model. We seek a framework which is both theoretically sound and physically...

Inelastic Mechanisms in Dynamically Loaded Ceramics
The dynamic response of ceramic materials has been the subject of intense research in the past decade. In this paper, we succinctly describe a plate impact experiment of a star-shaped...

Dynamic Effect of Sediment on Dam Hydrodynamics
The dam-reservoir-foundation interaction problem has been studied by many investigators. A two dimensional model of compressible porous media is employed to analyze the dynamic response...

Wave Loading Linearization for Offshore Structures
The linearization of Morison-type wave loading is to replace u|u| by cu, where u is a zero mean, stationary Gaussian random process and c is a constant. In the present study an optimal...

Dynamic Responses of the Precision Segmented Reflector
This paper concerns a structural simulation effort aimed at studying dynamic responses of the Precision Segmented Reflector when subjected to seismic disturbances. The study results indicated...
