Which mechanism leads to increased stream flooding in mountainous regions following extensive deforestation?

A)Reduced evapotranspiration increasing runoff volume
B)Increased soil infiltration decreasing surface flow
C)Enhanced interception reducing groundwater recharge
D)Decreased channel roughness slowing stream velocity

💡 Explanation

Following extensive deforestation, reduced evapotranspiration occurs because fewer trees are available to absorb and release water vapor, increasing runoff volume as there's less water returning to the atmosphere. Therefore, increased stream flooding results, instead of reduced flows, recharge reduction or slower velocities requiring altered hydrological cycle components.
