Aerial Survey of Moserbaer Barrage
Fluvial actions influence structures greatly. With regular abrasion and deposition activities of a river, it is important to check the strength and condition of structures like dams and bridges which have their foundations under water. One such topographical survey was conducted by GarudaUAV to check the impact of fluvial activities on a barrage situated on Sone River in Annupur District of Madhya Pradesh.
For the project, total stations and benchmarks were used for positional accuracy, DTM was cleaned and classified, contours were created, a 3D model was generated along with a Cross-section of the right bank of the barrage and an L-section of a 6m long walkway.
The study aimed at checking any subsidence of land under water at the right bank of the barrage and the refilling/uplifting it to the desired level. A slope comparison was also done to check for any encroachment and deviation from the proposed plan.
