Table 2 Terrain erosion susceptibility classes derived from the reclassification of TESI
Terrain erosion susceptibility classes | Area (km2) | Area (%) | Probability of terrain erosion |
|---|---|---|---|
Nil | 367.84 | 17.47 | No chance of erosion, mostly low lying areas. |
Low | 572.01 | 27.17 | Very low probability. Mostly affected by the run-off from the higher elevation |
Moderate | 544.77 | 25.88 | Medium probability, may directly involve in erosion or affected as part of falling from the top |
High | 313.22 | 14.88 | High certainty of erosion either as slide or gullying. Need attention in such areas crossing road sections. |
Very High | 217.31 | 10.32 | Very high certainty of erosion either as slide or gullying. To be monitored during the heavy rainy seasons. |
No data | 89.85 | 4.27 | No data is available due to cloud and shadow in the image. Not considered in the analysis |
