TRQDM (Return Time of the Quasi Dynamic slope stability Model)
This program is free software. This program is distributed in the hope that it will be useful, but without any warranty; without even the implied warranty of merchantability or fitness for a particular purpose.
TRQDM is a module for the calculation of the return time from the critical rainfall map spatially distributed under the scaling hypotheses to IDF (Intensity Duration Frequency) relationship. In the Figure 1 is showed the interface of the program.
