Calculate volume of adjacent cells, so you get total volume in groups of depressionsvolumes

I've got a raster that represents the water depth at a specific return period for a whole municipality (e.g. a lot of cells both with neighbours and single cells). The grid is a 10x10 m, so I know I can calculate the volume of each cell as depth x 10 x 10.


What I then need is to group these together, so that I get the sum of all connected cells, preferably I then need to convert that to a vector/area/polygon with the total volume.

So basically all individual raster cells that touch each other need to be summed up and grouped together.

I've got 3d analyst and spatial analyst license along with Standard Arc license.



Any help would be much appreciated.
