Antecedent precipitation was positively associated with erosion in
channels and sidewalls, possibly due to reduced infiltration, increased
runoff, and sediment yield. This result is in accordance with the high
correlation found between precipitation and erosion aggregated to natural
precipitation cycles. Interestingly, antecedent precipitation has not
been included in other precipitation–erosion studies. However, one
study in Ultisols in Georgia, USA (humid subtropical climate) found
that antecedent water content of soil was associated with increased
runoff but decreased sediment yield
