Abstract: A companion paper by Chang and Hills, 1992, describes the stress distribution in a soil surface during water droplet impact according to a numerical simulation model. This project was undertaken to relate field data to the ...

Abstract: The water infiltration rate during sprinkle irrigation is known to decrease due to the impact effects of water droplets on soil‐surface structure. In this paper, a numerical simulation model that employs full three‐dimensional ...

Abstract: A pilot‐scale treatment system, for developing drip‐irrigation pretreatment criteria, was designed, installed, and operated intermittently over 5,300 h using activated sludge secondary effluent. Principal unit processes ...
