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...

Response of Advanced Composite Space Materials to Thermal Cycling
In addition to microgravity and lack of atmosphere, the space environment provides intense radiation of both penetrating and nonpenetrating types. This paper focuses on the cyclic radiational...

21st Century Astronomical Observatories on the Moon
The advantages and disadvantages of building astronomical observatories on the Moon are described. In many ways, the Moon is a superior environment for astronomy to that of the Earth's...

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...

Reinforced Concrete Column Reliability
A method is proposed whereby the reliability is obtained using the stable configuration approach of structural system reliability. The configurations are defined based on imposed strains...

Mechanical Properties of Model Ice Rubble
Experiments were conducted to measure the mechanical properties of bulk ice rubble. Tests were performed under isothermal and plane strain conditions. Fresh water ice blocks were used...

Microcomputer Assisted Bridge Rating
Before microcomputers can be useful to those officials responsible for rating the approximately 576,000 bridges in this country, software systems must be developed to analyze and rate...

Evaluation of Sediment Transport and Friction Factor Equations Using MOBED
Three sediment transport rate equations and the same number of friction factor equations for mobile boundary channel flows were evaluated using a mobile boundary flow model called MOBED....
