Testing of Outlet Works Emergency (Guard) Gates Under Unbalanced Head Conditions ? Background and History
The U.S. Bureau of Reclamation has responsibility for ensuring the proper operation, maintenance, and safety of over 300 dams and reservoirs throughout the 17 Western States. Storage of...

Furrow Irrigation Education
A furrow irrigation simulation computer model based on the volume-balance method is described. The model is used to develop information on furrow system performance that can be used in...

Optimal Commands in Border Irrigation Systems
Optimal command areas and level border irrigation design parameters are obtained for a given available seasonal water supply using a dynamic programming (DP) optimization approach. The...

An Irrigation Allocation Planning Model
An irrigation allocation model using multiperiod linear programming was developed to recommend canal water allocation among different irrigated fields to maximize net annual benefits for...

A Flexible Expert System Based Typology of Irrigation System Types
This paper describes an approach developed to classify irrigation systems into categories. It discusses the general problem of developing a typology of irrigation systems and proposes...

Development of a Hydrological Database for PROSIM?A Water Rights-Based Operational Simulation Model of the Provo River
The development of a hydrological database for a computer model of the hydrology, water rights, and operations of the Provo and Weber rivers is described. The model uses all pertinent...

BASIN 2.0 for the Design of Level-Basin Irrigation Systems
The purpose of this paper is to present a computer program for the hydraulic design of level-basin irrigation systems. The first of three design modes provides design based on the advance...

CPIVOT v 2.0 Center Pivot Analysis and Design Software
A micro-computer based software package is presented which can be used for hydraulic design and/or analysis of center pivot irrigation systems. The software is written in C and requires...

Comparing Bowen Ratio-Energy Balance Systems for Measuring ET
Two Bowen ratio-energy balance (BREB) systems for measuring evapotranspiration (ET) under wet and dry conditions were compared. The study sites were an irrigated grass sod near Kimberly,...

Growing Season Evapotranspiration and Crop Coefficient
The Bowen ratio-energy balance (BREB) method was used to continuously estimate 20-minute actual evapotranspiration (ETa) in the middle of a 36-ha...

Streamflow Depletions and Water Transfers in Idaho
In the state of Idaho, streamflow depletions are quantified utilizing parameters of rate of flow, total volume diverted, and volume consumptively used. This paper summarizes the engineering...

Streamflow Depletions for Water Transfers in Utah
All inter- or intra-state transfers of Utah water rights must be accomplished by application and receive the approval of the Utah State Engineer. This paper summarizes the engineering...

Streamflow Depletions Considered in Water Transfers
In the State of Colorado, streamflow depletions are defined as that amount of water diverted to beneficial use minus return flows to the stream system. This paper summarizes the engineering...

Evaluating the Facts in Water Right Changes
Under the western system of appropriation water rights may be separated from the land and the time, type and place of use changed. Such changes are governed by the principle that there...

Soil Moisture Monitoring Using a Portable Capacitance Probe
Accurate monitoring of soil moisture has long been in integral part of a successful agricultural management system. Water has increasingly become a valuable and much sought after natural...

Availability Analysis of Irrigation Systems for Improved Management
Availability of an irrigation system is defined as the ratio of time of successful system operation to total desired operation time. Operation is successful when the flow rate of water...

Evapotranspiration of Dry Beans with Drip Irrigation
Information about the effect of irrigation on dry bean production in the Southwestern Colorado is very limited. The primary objective of this study is to establish a crop water use (ET)...

Computing in Civil and Building Engineering
This proceeding consists of papers presented at the Fifth International Conference on Computing in Civil and Building Engineering held in Anaheim, California, June 7-9, 1993. The proceedings...

A Solid Waste Solution
Burgeoning growth and diminishing landfill capacity have been propelling Broward County, Fla. toward a solid-waste crisis. The county, located along Florida's southeastern...

Pioneer Highway
The 1993 Outstanding Civil Engineering Achievement Award goes to the $490 million I-70 Glenwood Canyon in Colorado. The final link in Interstate 70 from Baltimore, Md. to Cove Fort, Utah,...
