Water drop energy and soil seal properties

摘要: Rain properties (depth, drop size, and impact velocity) affect the infiltration rate (IR) curve final IR (FIR) of soils. Because is not a unique function rain depth or energy, objective this study was to find that determines soil. Simulated constant intensity (40 mm h −1 ), with 2.53- 3.37-mm-diameter drops, applied from heights 0.4, 1.0, 2.0, 6.0, 10.0 m on two soil samples: Ruppin hamra (sandy loam, mixed, Typic Rhodoxearalf), Ruhamaa loess (silty Calcic Haploxeralf). The FIR soils decreased increasing kinetic energy (KE) drops. sandy loam less stable than silty seal formationin it more susceptible KE decay process better correlated momentum KE. Thus, prediction for given exposed rains various sizes velocities best based stability
