DRAINFILEPRO 2011

This software must be used to calculate the distance between draining trenches in landslides, using prefabricated panels DRENOTER in alternative to gravel and pipe. It is possible to calculate the distance of the drains according Hooughoudt's theory.
First step is to insert the data in the first sheet (mean rain, length of drain,permeability over the drains, permeability under the drains,depth of the drain); the program calculates the distance of the trenches, according to the Kfitting value. In the second step must be inserted the soil parameters to calculate the push on the draining panels and slope of the trench; the program will compare the requested flow rate with the expexted flow of the draining panels DRENOTER at a defined depth (Kglobal).
Basing on the Kglobal (> o < 1) designer is invited to change the parameters of the project in the previous steps of the software
