Effect of Flood Parameters on Lateritic Slope Erosion
Knowledge of erodibilty of lateritic slopes under flood conditions is essential to assess the safety of the slopes under flooding. Laterite being extensive in the state of Kerala makes the study of its slope stability necessary. Many investigators have attempted to quantify erodibility of clay and sand. The present study aims at identifying and quantifying the flood parameter affecting the erodibility of lateritic slopes. A three-stage setup was used to achieve that, the three stages being an inlet tank, a test tank that contained the soil slope, and a collection tank coupled with a sieve. A jet of water from the inlet tank is allowed to hit the lateritic slopes. The water in the test tank is allowed to rise until a certain height, and this height is maintained. The eroded soil is then collected on the sieve of the collection tank, and its dry weight and total solids of the water containing the total eroded soils were measured. The flood parameters are the velocity of the flood, the height of the flood, and the duration of the flood. The tests are carried out under different constant velocities, the different height of flood and varying duration of flood, and its effects of each parameter were studied. The erodibility of lateritic slopes was quantified using the weight of eroded material, and the flood parameters were identified as the velocity of the flood, duration of the flood, and height of the flood.
