Understanding Generator Static Excitation System
This paper explains some of the basic terms and features associated with a static excitation system (SES) to enable non-specialists to specify it according to their requirements. A simple...
Considerations to Be Taken in the Design of Speed Increasers for Hydroturbine Service
The paper discusses the incorporation of a speed increaser specification that is primarily functional yet one that will address the cost, reliability, efficiency, and life requirements...
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,...
Polyhedral Substitute Yield Conditions in Plastic Reliability Analysis
The method of invariant linear combinations of linearly associated lower bound safety margins is used for constructing upper bound approximations of the generalized reliability index with...
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...
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...
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...
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...
Coastal Habitat Protection in New York State
New York State's Coastal Management Program includes a specific policy for the protection of fish and wildlife habitats that are determined to be of statewide significance....
A Regional Screening Method for Classifying Pollutant Status of Coastal Waters
A regional assessment method has been developed to classify estuaries on the basis of their pollution severity, enabling resource managers to prioritize clean-up and future research efforts....
Use of Ocean Resources Criteria for Marine Tourism Planning and Management
A series of questionnaires and a modified weighting procedure developed by Gearing, Swart and Var were employed to obtain the ranking of ocean recreation criteria. An open-ended questionnaire...
Long Crested Weirs
A method has been developed to integrate and evaluate the head relationship between canal weirs and turnouts. The objective is to minimize flow variations through the turnout and at the...
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...
Sedimentation of Summit North Marina Connected to C&D Canal
Possible sedimentation problems at the proposed site of the Summit North Marina were investigated and reported. This brief paper summarizes the detailed results given in the report. The...
Reservoirs Help On-Farm Operation and Automation
Reservoirs can be used to convert a less desirable set of flow rates and durations into a more desirable and flexible set of rates and durations. This will permit irrigation management...
Winery Wastewater Land Application
Winery wastewater is characterized by low pH, relatively high BOD, and a low nutrient content. Land application using rapid infiltration basins has been practiced successfully at a number...
Steady State Fluid Transport Model for Plants
Knowledge of water potentials throughout the xylem and phloem elements as well as in individual cells is fundamental for understanding effects of water and temperature stress on transport...
Rating Curves for Adjustable Tricklers
This paper presents the approach and results of evaluating adjustable drip/trickle emitters to obtain rating curves. The emitter discharge depends on both system pressure and emitter opening...
