Most western state laws pertaining to prescribed burning do not specifically deal with range rehabilitation. Prescribed burns require a burning permit issued by the State Forester, or his equivalent, prior to ignition during closed fire seasons. Air quality standards have been…

This paper reports a detailed laboratory study of two-dimensional starting plumes. From dimensional analysis, equations in a parametric form for the motion of two-dimensional starting plumes are derived. The governing equations are also obtained from an approximate inviscid flow…
