Context:

Establishing a dynamic model of the water precipitation intensity-soil porosity and infiltration speed system offers the possibility of measuring the depth of water infiltration and soil moisture that produce landslides.

Methodology:

By applying system dynamics, a causal diagram of the geotechnical variables of two samples from sites affected by the mass movement phenomena in Pamplona (Colombia) was developed. The model was implemented using the Stella v9 software.

Results:

The simulation results show the variation of soil depth to be saturated in order to reach the liquid limit or a failure due to shear stress.

Conclusions:

The relation between mass movement and precipitation does not coincide with the current collective imaginary, but it depends on a characteristic set of precipitation values for each soil type.
