Hydrology problem. please answer ALL parts 4. The table below summarizes rainfall data for a storm event in a 250-acre watershed in Austin, TX. The total runoff during the storm was 115 ac-ft. The watershed soil is mainly alphalpha loamy sand. Time (hr) Rainfall (in/hr) 0-3 0.8 3-5 1.1 5-8 1.4 8-11 1.3 11-13 0.9 (a) Use the o index method to find the total infiltration during the storm event (in inches). (b) Use Horton's equation to find the total infiltration during the storm event (in inches). (c) How do the methods from parts (a) and (b) differ? Which do you think is a more accurate estimate of actual infiltration during the storm? Why?
