2. During a 10 hour rainfall, precipitations in Table are observed. Table: Precipitations (mm) hour total precipitation (mm) 0-2 38 2-4 26 4-6 12 6-8 24 8-10 12 a) Considering that initial infiltration capacity is 30 mm/hour, limit value of infiltration capacity is 5 mm/hour, Horton parameter --k-- is 0.3, calculate total infiltration and direct runoff. b) Assuming that depression and interception losses are ignorable,calcule and w indices.
