Supplementary material to "Including informal housing in slope stability analysis – an application to a data-scarce location in the humid tropics"

Abstract

Section 1 is divided in two parts: the first describes the new functionality developed in CHASM representing slope water management (S1.1); the second part illustrates its benchmark against another slope stability software (S1.2). S1.1 Description of slope water management in CHASMWe developed a new functionality in CHASM which is now able to simulate three additional processes: water leaks from buried septic tanks, leaks from superficial pipes and the effect of houses without roof gutters discharging rainwater onto slopes.Leaking Septic tanks: the user can determine the position of the tanks, their dimensions (width and depth), the leakage rate (m 3 s -1 ) and the type of leakage (local or evenly distributed). Considering that the slope cross section is represented with a mesh
