Model for Optimal-Risk Based Water Distribution Network Design
Various models using a variety of optimization techniques were developed for determining pipe diameters, network layout, pump capacities, and other design parameters. The objective function...

Traveling Trickler Center Pivot Design
There have been a number of proposals to improve the center pivot irrigation system in order to overcome the inherent inefficiency from high evaporation losses and energy requirements....

Intense Storms and the Runoff Coefficient
During prolonged, intense storms the runoff coefficient increases in value and approaches one irrespective of the vegetation and soil characteristics of the watershed. As the runoff coefficient...

Unique Flood and Drainage Problems in Los Angeles
Storm drainage for the coastal cities has to traverse highly used sandy recreational beaches. Due to new requirements on the construction of storm drains to the ocean, a beach outlet has...

Feasibility Study of Flood Control for the Maumee River in Allen County, Indiana
In March, 1982 the Maumee River overtopped its banks flooding parts of the City of Fort Wayne and unincorporated areas in Allen County, Indiana. The estimated damage to the area was about...

Hydraulic Modeling for Ecological Research
Because of the problems and expenses of a continuous data collection program for large rivers, it was decided to develop an integrated hydrodynamic and biological model for the Illinois...

Organization Design of a Water Resources Institution
An overview of the field of organization design is presented along with a brief description of major macro-organization design theories. Utilizing this information, four water resources...

Submerged Vanes for Sediment Control in Rivers
A procedure is developed for a rational design of a system of submerged vanes for depth control in alluvial-river channels. The vanes are vertical, small-aspect ratio foils installed on...

Classification and Behavior of Meander Migration
Meander migrations on the Mississippi River between Cairo, Illinois and Baton Rouge, Louisiana for the time period between the years 1765 and 1930 were classified into six categories based...

Continuous Modelling of Downstream River Erosion Caused by 40 Years of Urbanization
The US EPA Stormwater Management Model (SWMM3) was installed on an IBM-PC compatible network. The adapted program, known as PCSWMM3, and incorporating a simple algorithm for modelling...

Sediment Intrusion into the Substrate of Gravel Bed Streams
A physically-based model was developed to simulate the intrusion of fine sediments into stream gravel substrates and its effects on intragravel flow. The model is capable of simulating...

Physical Habitat Simulation and the Moveable Bed
One objective of an instream flow analysis is to quantify a flow that will maintain the existing channel and/or flush fine material from the bed. Five empirical approaches to determine...

Technology Transfer: Consultants and Counterparts
The results of an investigation into the transfer of technical knowledge between and among foreign consultants and their host country counterparts at two large-scale development projects...

Sedimentation at Canal In-Line Structures
This paper describes the procedures used to compute the transport capabilities of existing canals and the process for predicting sediment deposition that will occur at or near the modified...

Modeling Erosion and Sedimentation in Irrigation
Sediment yield and erosion modeling approaches for sprinkler and surface irrigation are discussed. Empirical approaches, such as the ULSE, and other regression approaches and their applicability...

Advancements in Aerodynamics, Fluid Mechanics and Hydraulics
The theme of these Proceedings is Advancements in Aerodynamics, Fluid Mechanics, and Hydraulics. As indicated by the title, the subject crosses disciplinary boundaries and deals with flow...

Production Analysis of the Cat 245 Hydraulic Hoe
The productivity of two Caterpillar model 245 hydraulic backhoe excavators was analyzed during their use on a highway construction project in September 1983. The hoes were working in a...

The Past, Present & Future of Earthmoving Scrapers
This paper is a summary of the history and development and use of earthmoving scrapers. It will also take a look at the future of this type of machine. We'll build the discussion...

Lessons Learned from Design, Construction, and Performance of Hydraulic Structures
The intent of this publication is to provide lessons learned, both positive and negative, from activities associated with design, construction, and performance of hydraulic structures....

Keeping Sand at a Standstill
Construction of roads, railroads, pipelines and other facilities removes the native vegetation from sand dunes. As a result, sand movement starts and entire dunes may become active. This...
