Currently, I am working on a Remote sensing-based approach for capacity estimation of a reservoir. for comparison purposes, I want to mention the expenditure of the hydrographic survey approach against the remote sensing approach.
Generally, the reservoir authorities require consultancies to carry out the hydrographic survey which is accurate and expensive, Remote sensing approach provides this survey with free of cost.
Please ReF:

These are also mostly done departmentally in most parts of India.
And in my view with Satellite imagery, using drones and flow meters, it may not cost much.

Thanks everyone for your suggestions.
I also require information regarding cost parameter of hydrographic surveys per unit area or unit length .
Kindly for accuracy and proficiency contact the international consultancy office "FINTECS Consultants" [email protected]
The cost per unit area is very location specific. Its difficult to come up with a number. If you use an eco-sounder it can easily cover an area of about 1km2 in a day. And for processing it another 1-2 days in office. For conducting hydrographic survey you have to consider the boat hiring cost also.
