Transient Fluid-Structure Interaction of a Cylindrical Tank with a Flexible Baseplate
Analytically predicted coupled natural frequencies, response functions, and transient responses are compared with measured values for a partially filled cylindrical tank subject to excitation...

A Pseudo Response Spectrum Method for Mark I Loads
A pseudo base motion response spectrum method is developed to uniquely evaluate the periodic condensation oscillation and chugging drag loads that may occur on submerged structures within...

Stress Distribution Around the Equipment Hatch Opening of a Prestressed Concrete Containment for a PWR Power Station
Results are reported of a finite element stress analysis for the linear elastic deformation around the equipment hatch opening in prestressed concrete containment. The dimensions and form...

Waste Phosphatic Clay Disposal in Mine Cutsr
Research was undertaken to assess the applicability of waste clay disposal back into phosphate mine cuts. The pit was monitored for two years with measurements of clay surface elevation,...

Influence of Roughness on Velocity and Dispersion at Low Flow
Dependence of the hydraulic and transport characteristics of low flow on channel roughness is investigated. Empirical expressions are used to estimate roughness coefficient as a function...

Effects of High Sediment Concentrations on Velocity and Sediment Distributions
Several classifications are required to describe sediment-transporting flow. The flow may be turbulent or laminar, Newtonian or non-Newtonian, and may also have a uniform or nonuniform...

Prediction of Dam Overtopping Due to Mudflows
The eruption of Mount St. Helens on May 18, 1980 resulted in a small mudflow into Swift reservoir, which is located immediately south of the mountain. An engineering/geologic study was...

Optimal Real-Time Operation of a Cascade of Hydropower Plants in Central West China
The Longxihe River hydropower system consists of four hydropower plants in series. The four reservoirs are used for flood control and power generation. Among the four reservoirs, only...

Artificially Varied Flow: River System Management
Some of the major water quality problems are heat, color, organic sediment, and total dissolved solids. To dilute these and other pollutants, substantial augmentation of flows for water...

Sensitivity of Model Choice in Reservoir Design
The Box-Jenkins method of model construction and tests of model adequacy and fit are applied to a reservoir design problem. The sensitivity of the stochastic models used to generate synthetic...

Modeling Pool and Riffle Sequences in Alluvial Channels
A one-dimensional mathematical model has been developed to predict the hydraulic characteristics of alluvial channels under low flow conditions. For a given steady discharge, channel geometry,...

Measurement of Ice Forces on Structures
Methodologies and techniques are discussed for measuring ice forces on fixed structures situated in rivers and lakes. The usual method of measuring ice forces is to place a load frame...

Hydrologic Applications for Electronic Spreadsheets
Electronic spreadsheets have many potential applications to civil engineering. They are ideal for the derivation of unit hydrographs and the construction of design storm hydrographs. They...

Flood Consideration for Sanitary Structures
An approach is presented to determine the design basis flood for Sanitary Structures and means to protect them. Flood and flood frequency are defined. Principal classes of flood are evaluated...

A Guide for the Field Testing of Bridges
The history and present use of bridge testing are reviewed. The benefits of bridge testing include safety and reliability, the money saved by not constructing a new bridge, the improvement...

How about Reverse Filters
Reverse or inverted filters allow water to drain freely without carrying away suspended solids. Their pore size must be properly related to the fines being protected. Terzaghi's...

Acid Rain
Current information on acid rain is reviewed in eight papers presented at an April, 1979 session sponsored by the Research Council on Environmental Impact Analysis of the ASCE Technical...

Urban Transportation Planning
Sources of Information on Urban Transportation
This book is a review of the procedures followed in the comprehensive urban transportation planning process including a history of its development, trip generation, trip distribution methods,...

Pile Foundations and Pile Structures
This manual, Pile Foundations and Pile Structures, is an assembly of data relating to pile foundations and pile structures which is intended...
