The lag time between peak rainfall and peak stream discharge is typically increased by urbanization.

Question

Quizplus · Accepted Answer

Urbanization can increase the amount of impervious surfaces like concrete and asphalt, which can prevent rainfall from infiltrating into the ground and instead direct it to stormwater systems. This can result in a more rapid runoff and increased volume of water reaching streams, leading to a shorter lag time between peak rainfall and peak stream discharge.
