Abstract
- The paper investigates the catchment area extension calculations as a function of the adopted spatial resolution and the effect of these spatial resolutions on the runoff calculations, for a number of catchments. Calculations were done with hypothetical and constant amounts of precipitation over space. Adopted grid size varied from 3000 to 2 m. Area estimate errors were computed in respect to 2 m grid resolution and the SCS method used for excess precipitation calculations. Results have shown that 75% of the catchments have errors of
