Bedrock erosion rate and Bedrock erosion threshold

[Marina Refatti Fagundes]

Hello everyone!

I´m using CAESAR-Lisflood to evaluate the erosion and deposition in a stretch of a river in a small moutainous catchment in south Brazil. The model is running well, but my results are a little bit weird. The resulting erosion and deposition values are between -40 and +40m, which is a lot considering that I am only simulating an event with a total duration of two weeks.

In this way, I would like to know if you have some suggestions of values to the parameters Bedrock erosion threshold (Pa) and Bedrock erosion rate (m/Pa/Yr). If I let this parameters with a value of zero, no erosion and deposition occurs. If I change theis values, the erosion and deposition become too large.

Thank you!
