How do you calculate storage capacity of a dam in tmc?

To calculate the storage capacity of a dam in trillion cubic meters (TMC), you first need to determine the reservoir's surface area and the average depth. The storage capacity can be estimated using the formula: Capacity (TMC) = Surface Area (hectares) × Average Depth (meters) × 0.00001, where the factor 0.00001 converts the volume from cubic meters to trillion cubic meters. Ensure that the measurements are consistent and converted properly for accurate results.
