Hydrologic Design Criteria for Dams with Equal Reliability
Appropriateness of design criteria which require using the same Antecedent Moisture Condition (AMC) throughout Kansas for sizing dams and emergency spillways was examined. AMC values which...

Bowen Ratio and Penman: Australian-California Tests
Results are presented of evapotranspiration (ET) studies conducted in Davis, California and at two locations in Australia. Good agreements were obtained in early comparisons of Bowen Ratio...

The Relationship of Benefits to System Size for Irrigation Projects
This paper presents a generalized linear programming (LP) and farm budget model for optimization of on-farm irrigation benefits resulting from variations in irrigation project size. The...

Considerations for Sizing Water Delivery Systems
The purpose of a water delivery system is to deliver irrigation water to a farm and its design should be based on meeting the requirements of farm water use. The rate, duration and frequency...

Daily Diversion Forecasting for a Large Irrigation Project
A procedure has been developed and tested to forecast demand-type large irrigation diversions on a daily basis. The model is based on hydrologic concepts as well as irrigation scheduling...

Irrigation District Management?Past, Present and Future
This paper reviews the significant changes in the policies and procedures followed by agencies formed to deliver irrigation water in the western United States generally and California...

ARS Water Data Bank?A Storage System for Hydrologic Data
Precipitation and streamflow records are considered basic for all hydrologic studies, and are an important product of water research projects in the Agricultural Research Service (ARS)....

Crop-Water Production Functions and System Design
A Task Committee to evaluate application of crop-water production functions to irrigation system design and management was established by the ASCE Irrigation Water Requirements Committee...

Meixner Functions Model Crop Yield vs. Applied Water
Most crop production functions are reported as linear functions even though everyone knows they are not. The few examples of non linear crop production functions that exist in the literature...

Economic Analysis Tools for Differential Inflation
Economic decisions based on a life-cycle analysis should consider differential increases or decreases in operation and replacement costs and benefits over the project or component life....

Runoff Model for Watersheds of Nonhomogeneous Characteristics
A watershed of any configuration, topography, and spatial distribution of cover, soil and channel characteristics is described as a plannar grid. Time-varying precipitation is applied...

An Integrated Rehabilitation Procedure for Gravity Systems
Demands for an improved system combined with a more adjusted management mode are common in many projects where limited or strained budgets do not allow for a regular and secure water supply....

California's Dam Safety Program?The Development of Hydrology for Dams (abstract)
California's water code provides for supervision of dams and reservoirs with regard to protection of life and property. This code is administered by the Department of Water...

Report of Task Committee on the Collection and Publication of Basic Water Resources Data
In 1983 members of the Irrigation and Drainage Division's Committee on Surface Water expressed concern over reductions in funding for data collection and publication programs in the United...

Forty Years of Computational Hydraulics?1960-2000
The definition of computational hydraulics as used herein is: the application of numerical methods for the solution of problems of hydraulic flows, largely as practiced by the civil engineering...

Coastal Zone '87
Coastal Zone '87 is the fifth in a series of multidisciplinary meetings on comprehensive coastal and ocean management. The papers included in this publication review technical...

Liberty Restored
The Outstanding Civil Engineering Achievement of 1987 is the restoration of the Statue of Liberty in New York Harbor. The restoration work included many engineering tasks that by themselves...

Design of Steel Transmission Pole Structures
This document has been carefully prepared in an effort to provide an authoritative source of information about effective design and fabrication of steel transmission pole structures. The...

Aspects of Wind and Earthquake Dynamics of Cable-Stayed Bridges
In the course of dynamic analysis of long-span cable-stayed bridges for the effects of earthquake and wind, a number of observations have been made that may be of interest to designers....

The Applicability of Satellite Altimetry Data to Tidal Models
Different tidal regimes require different data assimilation schemes. In all cases, however, it is better to perform a separate tidal solution before assimilation. For proper assimilation...
