Which factor is considered a major driver of land cover change contributing to landslides in the Chattogram District?
|
Hill cutting and unplanned urbanization |
|
Hill Cutting and Unplanned Urbanization are significant contributors to landslides in mountainous or hilly areas like Chattogram. Cutting into hills for construction or infrastructure development disrupts the natural slope stability, making the area more prone to landslides, especially during heavy rainfall or other triggering events. Unplanned urbanization further exacerbates the risk by increasing impervious surfaces and altering natural drainage patterns. |

What does the ROC value for a model indicate in the context of this study?
|
The accuracy of the model in predicting landslide susceptibility |
|
The ROC value is used to assess the performance of a classification model, particularly in terms of its ability to distinguish between classes (e.g., landslide-prone and non-prone areas). The ROC curve plots the true positive rate against the false positive rate, and the ROC value (often represented as the AUC, or Area Under the Curve) reflects the model’s ability to correctly classify the susceptibility to landslides. |
