Show answer and explanation

Correct answer: (A) (P)-(IV), (Q)-(III), (R)-(V), (S)-(I), (T)-(II)

Explanation

Horton describes infiltration (IV), Penman estimates evapotranspiration (III), Chezy gives flow velocity (V), Lacey designs alluvial channels (I), and Dicken estimates flood discharge (II).

The complete match is **P–IV,Q–III,R–V,S–I,T–II (A)**.
