![]() When steady concentrations were not reached, the subsequent event produced effluent concentrations that increased gradually to steady state. If steady-state concentrations were reached for a particular size class, that class’s effluent concentration peaked rapidly in the next rainfall event, then declined gradually to its steady-state value. Steady state concentrations were, however, dependent on the rainfall intensity. Results showed that short-time soil erosion was sensitive to whether steady-state erosion was achieved during the preceding event, although consistent steady-state effluent concentrations were reached for each sediment class. Sediment concentrations at the flume exit reach steady-state conditions over time scales that increase with sediment size, and experiments were designed such that both steady and non-steady effluent concentrations were reached in H7-E1. However, the initial bulk density and moisture content were increased before the two others events using different pre-wetting followed by 22h of air-drying. The soil was hand cultivated and smoothed before the first event (H6) only. In each experiment, one flume was bare while the other had 40% rock fragment coverage. Three experiments denoted H6, H7-E2 and H7-E3, involved the same precipitation rate of 74 mm h-1, but using the different initial conditions. “I totally believe that we’re a living laboratory here with a plethora of architectural design and sustainable environmental practices to share,” Bob Dixson, a retired postmaster who was the town’s mayor during the rebuilding, told the Washington Post.The effect of antecedent conditions on precipitation-driven soil erosion dynamics through multiple rainfall events was investigated using a pair of 6-m
