In the process of updating the RDKB floodplain maps, fluvial geo-hazards (such as alluvial fans) were also mapped. Four of the mapped alluvial fans were classified (moderate hazard, high hazard and very high hazard); with the remaining alluvial fans left unrated.
The location of the unrated alluvial fans identified through the recent RDKB floodplain mapping project are shown below. If you have any questions, please reach out to [email protected].
