TOOL FOR MONITORING HILLSLOPE STABILITY CONSIDERING PRECIPITATION DATA

Abstract

This work presents a methodology applied to the monitoring of slope stability in a rural area in Manizales, using the hillslope-storage Boussinesq (HSB) partial differential equation. This was applied with theoretical information of geotechnical parameters, such as porosity, hydraulic conductivity, thickness and data obtained from indirect measures such as the angle of the hillslope, width of the hillslope, profile of the hillslope and precipitation. In this work, the HSB equation was solved with the finite differences method by applying the python programming in four days of precipitation. The precipitation was reported by the EMAS meteorological station. The result was the saturation curve and its safety factor for each daily record of precipitation in each one of the scenarios given, when varying depth along the hillslope. This methodology can contribute to the monitoring of hillslopes located in rural areas as long as the values of the geotechnical parameters are adjusted, enabling to add to the efforts aimed at an early warning system for the hazard of landslides.
