Cost Distance Calulation

Hi,

I wish to use the cost distance calculation to calculate the accumulated least cost of travelling from river bank to any point in dem.

The Cost distance calulation adds each cell value in the least cost path together to give a cell value.
However,I want to get the value of the difference between the elevation of the least cost path point of origin on the river bank  and its respective cell value in the dem. This would give a measure of the cell elevation  in respect of its closest point height wise on the river bank.

So for instance, calculate if the cell is 10 metres higher than the cell on the river bank you would arrive at by following the least cost path to the river from it.

How can I acheive this?

Thanks,

Liam
