Riprap Design by Modified Safety Factor Method
The Safety Factor method for designing riprap is based upon straight forward physics combining rock properties and flow characteristics. M.A. Stevens developed the method by summing the...
Interfacial Instabilities Associated with Density Currents
Three-dimensional behavior of density currents flowing down a sloping surface has been analytically and experimentally investigated. Attention has been given to the presence of interfacial...
Overview o New England Coastal Flood Study Methodology
This paper presents an overview of the development of methologies used to determine the probabilistic flood levels for New England coastal flood insurance studies. The Federal Insurance...
Kinematics and Dynamics of Overland Flow
C. Y. Guo combined the kinematic wave approximation with Horton's infiltration formula to analytically solve the propagation of a two-dimensional overland flow on a previous...
Model-Prototype Study of Overland Flow
Similarity of overland flow hydrographs was investigated. Similarity ratios based on Froude number modeling were tested by using: 1) computed hydrographs by kinematic wave equations, 2)...
One-Dimensional Modeling of Dam-Break Flow
R.W. MacCormack method is used for the numerical integration of Saint Venant equations to simulate the propagation of one-dimensional dam-break wave. The computed water levels are compared...
Hydrodynamic Response of an Estuary to Storm Forcing
Previous work on the response/sensitivity of an estuarine hydrodynamic model to the choice of model parameters is extended to include a preliminary consideration of wind-generated waves....
Mathematical Model of Wave Induced Pressures
A two-dimensional, implicit finite difference model was built to compute surface wave induced pressures under a gravity base foundation. The results showed considerable wave attenuation...
Alternate Designs for the Sidewalls of Hydraulic Jump Stilling Basins
This paper discusses several alternate designs to replace the full height sidewalls of a type 2 U.S. Bureau of Reclamation stilling basin. The alternate designs that were investigated...
Measurement and Analysis of Tracfcfifc-Induced Transient Motion in Navigation Channels
Two-induced physical effects related to navigation changes on the Kanawha River, West Virginia were measured at three environmentally sensitive representative locations. The purpose of...
Hydrologiic Risk Analysis for Small Dams in Missouri
A methodology is presented for calculating the risk cost for a dam based on probabilities for rainfall depth, antecedent moisture condition, rainfall time distribution, initial reservoir...
An Error Analysis of the Dynamic Wave Model
The Dynamic Wave Operational Model (DWOPER) is used to forecast river stages on the Lower Columbia River. DWOPER was developed by the National Weather Service's Hydrologic...
The Physics of Sediment Transport by Wind and Water
Sponsored by a special projects committee under the guidance of the Sedimentation Technical Committee of ASCE. This collection contains noteworthy,...
Simulation of Long Period Ground Motions for a Large New Madrid Earthquake
Ground motions for a large New Madrid earthquake are simulated to provide response spectra in the period range of 0.5-20 seconds for hard rock sites at Chicago and Atlanta. The ground...
Mitigation of Seismic Effects on Water Systems
Historically, earthquakes have caused damage to water systems. In this paper, water system facilities at risk due to seismic activity as well as potential damage mechanisms are identified....
Performance Characteristics of Structures, 1985 Mexico City Earthquake
The 1985 Mexico City earthquake caused major damage to buildings, but not other structures, in the center of Mexico City, located approximately 400 km. from the epicenter. Due to soil...
Waves in the Water Works
The 1986 amendments to the 1974 Safe Drinking Water Act are far reaching laws that may affect many drinking water utilities across the nation in the next decade. Congress passed legislation...
The Oregon Coast Aquarium ? A Case Study
The Oregon Coast Aquarium, to be located in Newport, OR. , has been carefully developing over the past five years. Proposed as a coastal interpretive center, it will trace a water droplet...
Design of Breakwaters for Hurricane Wave Attack
The breakwaters protecting Port of Haina in the Dominican Republic have been repeatedly damaged by hurricane storm waves. Attempt to repair the destroyed portions have been largely unsuccessful....
Integrated Monolayer Flexible Revetment Technology for Coastal Protection
Fundamental considerations for flexible revetment design are given in some detail and the critical need for sound engineering in a total system design approach is strongly emphasized....
