Hayashi, M. and Quinton, W. L. 2004. A constant-head well permeameter method for measuring field-saturated hydraulic conductivity above an impermeable layer. Can. J. Soil Sci. 84: 255–264. Hydrologic understanding of mountainous and northern regions of Canada is poor owing to the lack of critical field data such as hydraulic conductivity. A portable field instrument, the Guelph permeameter (GP)...

In this study, we examine the consistency of a gravity-based predictive theory for hydraulic jump, given by Kurihara [ Proceedings Report Research Institute Fluid Engineering (Kyusyu Imperial University, 1946), Vol. 3, pp. 11–33]; Tani [J. Phys. Soc. Jpn. 4, 212–215 (1949)] with phenomenological condition at jump Rayleigh [Proc. R. London, Ser. A 90, 324–328 (1914)]; and Watson Mech. 20, 481–49...

In this paper, we describe the nonlinear outcome of spiral shocks in protoplan-etary disks. Spiral shocks, for most protoplanetary disk conditions, create a loss of vertical force balance in the post-shock region and result in rapid expansion of the gas perpendicular to the disk midplane. This expansion has characteristics similar to hydraulic-jumps, which occur in incompressible fluids. We pre...

Hydraulic jumps at the tail end of spillways are usually induced by baffle blocks or other obstacles. Such jumps can also be induced by jets that oppose the main flow. Another application is to back up turbidity currents in reservoirs by means of opposing jets. This measure can be adopted when transfer tunnels feed water into the reservoir at a higher elevation near the dam. Stopping the turbid...

Abstract A hydraulic-stepped spillway was designed using an aeration basin to provide aerated flow the stepped utilizing a hydraulic jump. However, through entrance of might separate from first step top and impact downstream steps at large unit discharge, causing so-called jet flow. new experimental study conducted better understand in hydraulic-jump-stepped with comparisons conventional spillw...
