The Performance of the SPH Method in Simulating Surface runoff Along a Saturated Soil Slope

Rainfall-induced slope failures are one of the most disastrous and frequently occurring natural hazards. Hence, it is indispensible to predict their occurrence and their post-failure velocity in order to save lives and properties in mountainous areas. The rain that falls on a soil slope results in...

Civil engineering (General) Rainfall-induced slope failures are one of the most disastrous and frequently occurring natural hazards.

The rain that falls on a soil slope results in either infi ltration or surface runoff, depending on the site characteristics. For saturated soil slopes, the amount of rain that goes as infi ltration is usually less than the amount that goes as runoff. As a result, surface runoff scours the slope surface, thereby removing the soil slope protecting covers and eventually putting the slope, at least, in a marginally stable condition.

The average velocity of fl ow using the smoothed particle hydrodynamics method was compared with the average value obtained using a standard open-channel hydraulics empirical equation.

The Performance of the SPH Method in Simulating Surface runoff Along a Saturated Soil Slope
description Rainfall-induced slope failures are one of the most disastrous and frequently occurring natural hazards. Hence, it is indispensible to predict their occurrence and their post-failure velocity in order to save lives and properties in mountainous areas. The rain that falls on a soil slope results in either infi ltration or surface runoff, depending on the site characteristics. For saturated soil slopes, the amount of rain that goes as infi ltration is usually less than the amount that goes as runoff. As a result, surface runoff scours the slope surface, thereby removing the soil slope protecting covers and eventually putting the slope, at least, in a marginally stable condition. This article reports the performance of the smoothed particle hydrodynamics numerical scheme in simulating runoff along a saturated soil slope with emphasis on predicting the velocity of fl ow. The average velocity of fl ow using the smoothed particle hydrodynamics method was compared with the average value obtained using a standard open-channel hydraulics empirical equation. The results show that the smoothed particle hydrodynamics method could be used as an alternative method for predicting the runoff velocity along a soil slope in hilly areas.
