RISIncorporating the Modified Orifice Equation into Pipe Network Solvers for More Realistic Leakage Modeling
Publisher: American Society of Civil Engineers
Abstract: It has been well established in several experimental and modeling studies that leak areas are often not fixed, but vary as linear functions of pressure. Replacing this linear equation into the orifice equation results in ...
Scouring Damage to Buried Pipes Caused by Leakage Jets: Experimental Study
Publisher: American Society of Civil Engineers
Abstract: This paper reports on an experimental study on the scouring of pipe materials on the outside of leaks caused by soil fluidization. A base experiment was designed consisting of a 3 mm diameter hole angled at 45° to the ...
An Interdisciplinary Field Study of the Energy and Water Fluxes in the Atmospheric-Biosphere System over Semiarid Rangelands: Description and Some Preliminary Results
Publisher: American Meteorological Society
Abstract: Arid and semiarid rangelands comprise a significant portion of the earth's land surface. Yet little is known about the effects of temporal and spatial changes in surface soil moisture on the hydrologic cycle, energy balance, ...
