Abstract: In many situations designers are faced with the problem of a building addition that requires new columns near, or directly above, existing foundations. Several design alternatives are usually considered, and frequently the ...

Abstract: Many canal control methods and algorithms have been developed, but only some of them are being used on operating canal projects. As a part of the ASCE task committee on canal automation algorithms, this paper discusses ...

Abstract: Approximate values for all the apparent real and imaginary characteristic roots of the general first order linear differential-difference equation are determined (primarily graphically) without ...

Abstract: The criteria needed for the design of a continuously operating constant torque spring slip clutch are presented. These criteria include a tapered arbor feature which permits the design of a ...

Abstract: Field tests were conducted to determine the pump characteristics at four pumping plants on the Southern Nevada Water Project. Each pump tested was instrumented to measure speed, torque, and ...

Abstract: USM is a hydraulic‐simulation computer program developed by the U.S. Bureau of Reclamation to analyze unsteady‐flow conditions in canals. The program USM uses the method of characteristics to solve the complete Saint Venant ...

Abstract: CANAL is a computer model that was developed at Utah State University to perform unsteady‐flow simulations for branching canal networks. This paper describes the features of the model and discusses its strengths, weaknesses, ...

Abstract: Different control algorithms for the regulation of irrigation canals have been developed and applied throughout the world. Each of them can be characterized according to several criteria, among which are: the considered ...

Abstract: To help evaluate and compare canal unsteady flow models, field data were collected from two operating canal systems: the Central Arizona Project and the Salt River Project. These two large projects in Arizona convey ...
