Abstract: The hydraulic transition between nonorifice and orifice flow regimes at a rectangular sluice gate was analyzed to determine the value of a coefficient

Abstract: This is one of several introductory papers resulting from work by the ASCE Task Committee on Irrigation Canal System Hydraulic Modeling. It is intended to serve as background for analyses by the Task Committee of several ...

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: When concrete pavement is subjected to a change in temperature, some time must elapse before a condition of equilibrium is again reached. In the transient heating and cooling processes that take place in the interim, there ...

Abstract: A series of detailed laboratory measurements were made under steady-state flow conditions through a 0.914-m (3-ft) Cutthroat flume in an attempt to more accurately define transition submergence for four standard throat ...

Abstract: Laboratory experiments are performed to study the conditions under which concrete scaling occurs. Induced temperature gradients causes the concrete surface to spall off in sheets, replicating an ubiquitous form of damage ...

Abstract: A volume balance approach to determine the parameters of the Kostiakov or modified Kostiakov infiltration equations in border and furrow irrigation is presented. The approach requires measured data from the advance phase, ...

Abstract: Four rectangular sluice gates were calibrated for submerged-flow conditions using nearly 16,000 field-measured data points on Canal B of the B-XII irrigation scheme in Lebrija, Spain. Water depth and gate opening values ...
