Can quarrying cause flood? The results of these models show that quarrying activities reduce flood hazards by creating catchments basins which detain and delay floodwaters during extreme rainfall. As opposed to public belief, the simulated maps show that quarrying does not enhance flood hazards and in fact mitigates its effects.
