अवधारणा:

राइव सूत्र:

QP = CR × A2/3

जहां QP = बाढ़ चरम निस्सरण, A = kmमें जलग्रहण क्षेत्र, और CR = राइव नियतांक। 

गणना:

दिया गया है; जलग्रहण क्षेत्र (A) = 8 km2, राइव गुणांक (CR) = 6

अधिकतम बाढ़ निस्सरण (QP) = CR × A2/3 =  6 × (8)2/3 = 6 × (23)2/3 = 6 × (2)2 = 24 m3/s

अतः विकल्प (3) सही उत्तर है।
