  1. The difference between corresponding values of two parameters for each of the 1154 one sqkm grids overlain across the basin surface has been first computed. Then the % difference was computed, again for each of these grids, by dividing the computed difference for each by the corresponding parameter value from which the subtraction is done, multiplied by 100. The mean of these % difference values for the 1154 grids has then been tabulated here
