Hello,
I've been checking the code for CAESAR and seem to have found a bug that will probabaly effect most versions from v5 onwards.
Its quite important, but you need to check whether or not it makes a difference to your simulations - it may well not.
To explain the error: for a while, I have set the code up to use mean bed slope to calculate the slope to determine flow depths. The function (mean_bed_slope(x,y)) has not been returning the correct values - it was returning the max, or the last +ve slope it checked.
This same slope function was used to determine Tau for erosion when using bedlsope.
As such it may effect all simulations, but more so those model runs using bedslope to calculate Tau.
I'm really sorry about this - and I hope that it has not effected your simulations... I thought it best to let you know ASAP.
I would advise checking them against the latest version of the code which I shall post on the website later on today (5.8g) Good luck, Tom |
