Abstract
AbstractRailway formation (embankments and cuttings) in Queensland are experiencing increased maintenance costs due to rainfall induced erosion and sedimentation problems. The erosion problems can be reduced by establishing grass cover on the steep slopes (batters). The objective of the research reported in this paper was to develop a continuous rainfall-runoff-soil erosion model to investigate grass cover effects on runoff and soil loss on railway formation steep slopes. It utilizes the Saint Venant continuity and momentum equations for overland flow, and a modified Green-Ampt model for infiltration on steep slopes. The erosion component of the model consists of two different methods, based on (1) the modified universal soil loss equation, and (2) steep slope erosion dynamics. The efficiency of the model was evaluated by the percentage error and the Nash-Sutcliffe efficiency values. Field trials data gathered from 10-m wide sections with different grass cover percentages were used to calibrate the one-di...
