Numerical Evaluation of Training Structures
A technique to evaluate estuarine training structure performance in reducing localized maintenance dredging requirements using the US Army Corps of Engineers TABS-2 numerical modeling...

Settling Tank Model for Deposition in a Tidal Lagoon
A model is developed to assess deposition of suspended sediment in Great Sound, New Jersey. The model employs the classic settling tank concept which utilizes plug flow hydrodynamics,...

An Overview of Factors Affecting Land Application of Food Processing Wastes
The food processing industry can use slow rate, rapid infiltration or overland flow systems. Slow rate systems are the most common method used for land application. The limiting design...

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...

Calibration of a Bridge Rating Formula for Overload Permits
This paper proposes a method to calibrate a reliability based load and resistance factor design (LRFD) permit evaluation formulation that will account for the overloaded truck's...

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....

Modeling Large Inelastic Cyclic Response of Concrete

Design of an Expert System for the Rating of Highway Bridges
A microcomputer-based expert system used to determine the effects of vehicles and overloaded vehicles on simple span bridges with reinforced concrete deck and prestressed concrete I-beams...

Capacity Rating of Existing Piers and Wharves
This paper outlines a method for physically surveying the present material condition of existing piers and wharves and assigning to them a safe rated capacity expressed in displacement...

Aerators on Spillway Chutes: Fundamentals and Applications

Optimum Design of Aeration Ramp Slots in Tunnel Spillways

Granular Flow: Industrial Problems Needing Solutions

Supercomputers and their Impact on Civil Engineering
The increasing complexity of today's civil engineering applications requires increasing detail and analyses with associated increased demands on computer resources. At the...

Super and Parallel Computers and Their Impact on Civil Engineering
This publication contains four papers on the use of super and parallel computers in the practice of civil engineering. The first paper shows how large nonlinear systems of equations, such...

Designing for Flow
Geotextiles used for in-plane drainage can carry surprisingly large amounts of water within their structures. These composite drains, known as sheet drains, prefabricated drainage composites...

Calaveras Pipeline Hydroelectric Project
The Calaveras Public Utility District (San Andreas, California) has a pipeline connecting its water treatment plant to the San Andreas Reservoir. By reducing the flow rate in the system...

Specification Writing for Small Hydro-Generators
For small hydro projects, it is all too common for the spec writer to use a convenient off-shelf spec usually written for a much larger unit. Minor modifications (primarily ratings) are...
