Large Low-Speed Generators with Skewed Supporting Parts
During the past decade, the demand for hydro-generators has been for increasingly high ratings, up to the present maximum of about 800 MVA. These low-speed machines have rotor diameters...

Flow Behavior of Kinked Strip Drains
Due to the often expressed concern over the axial deformation of strip drains and the resulting impact on flow rate, this study has been undertaken. A laboratory experiment has been constructed,...

Statistics of Concrete Shrinkage Test Data
The paper reports a large series of concrete shrinkage tests which can be used for statistical purposes. The series involves two groups of 36 identical cylindrical specimens, with a diameter...

DSS: A Dam Site Selector Expert System
The Dam Site Selector (DSS) expert system is an aid for rating an area for use as a dam site and reservoir. It was developed for use in a graduate level hydrology design course at Purdue...

Mathematical Modeling of Compound Channel with High Sediment Concentration
The mathematical model for erodible channels, FLUVIAL-12, has been extended to simulate the fluvial processes in the lower reach of the Yellow River in China. Fluvial processes in the...

Three-Dimensional Modeling of Cohesive Sediments and Pollutants in Surface Waters
Particulate and dissolved pollutant transport rates are predicted using a pollutant transport modeling system. The latter is a finite element model capable of simulating three-dimensional...

Ultimate Sediment Concentration
The sediment rating curve is used to relate sediment discharge to water discharge, under steady equilibrium flow conditions. The slope of the sediment rating curve is a measure of the...

Stochastic Characteristics of Cobble-Gravel Bed Load Transport
Prototype tests of stochastic characteristic of cobble-gravel bed load transport have been done in Dujiangyan reach of Minjiang River in China in 1977-1985. All of 718 sample data from...

Predicting Channel Recovery from Sand and Gravel Extraction in the Naugatuck River and Adjacent Floodplain
Gravel extraction at five sites along the Naugatuck River in Connecticut is of sufficient magnitude that channel recovery to pre-mining morphology is expected to require up to several...

Design of Riprapped Scour Holes for Flip Bucket and Overfall Spillways
Presented in this paper is a simple method of predicting pre-excavated scour depths and geometry for riprapped basins below flip bucket spillways. The input data needed for establishing...

Correlation Between Full Size and Half Size Inlets

The Liquid Droplet Radiator in Space: A Parametric Approach
This study is a parametric investigation of the performance and operating characteristics of a cylindrical Liquid Droplet Radiator (LDR) for use in space. The LDR system mass per heat...

Swedish Approach to Infiltration and Percolation Design
Design of infiltration and percolation facilities is similar to detention facilities. The storage volume of an infiltration basin being the ponding volume on top of the infiltration surface...

An Empirical Correlation of Bed Load Transport Rates in Flumes and Natural Rivers

Sand Transport by Wind: Transport Rates of Uniform and Graded Sand

Longshore Sediment Transport Rate Distributions Measured by Trap

Technique for Assessing Estuarine Sediment Pollutants
A technique was developed for the Mississippi Sound whereby all pertinent scientific data could be gathered and be assimilated in a format that would permit sediment pollution to be assessed...

Research of Littoral Transport Rate and Wave Energy Analyses of the Bay Inside the Wai-San-Ding Barrier of the Taiwan Strait, R.O.C.

Philosophy and Implementation of Gate Stroking
The purpose of this paper is to examine one control method - gate stroking - the philosophy which would lead to its selection and an example of its implementation. Gate stroking provides...

Modeling Cohesive Sediment-Pollutant Interaction in Surface Waters
Particulate and dissolved pollutant transport rates are predicted using a pollutant transport modeling system. The latter is a finite element model capable of simulating two-dimensional...
