- Title
Extreme events controlling erosion and sediment transport in a semi-arid sub-andean valley.
- Authors
Coppus, R.; Imeson, A. C.
- Abstract
Describes slope and channel processes that were actually observed by the authors in a second-order tributary of the Rio Camacho near Tarija in southern Bolivia. How different tributary streams and slope sections contributed sediments and flow to the main channel; Infiltration rates obtained through rainfall experiments; Description of the storm; Observations regarding rainfall intensity; Total suspended load discharge based on sediment loads carried by previous storms; Comparison of extreme events and less intense storms with respect to soil losses, erosion, and sediment transports; Results suggesting limitations of rainfall experiments in understanding geomorphic events; View that this makes modelling of erosion and soil losses a difficult and hazardous task.
