Solution
The discharge of a stream is calculated by multiplying its cross-sectional area by its velocity. This is based on the formula Q = A * V, where Q is the discharge, A is the cross-sectional area, and V is the velocity. The discharge is not constant for the length of the stream, it can vary depending on factors such as rainfall, snowmelt, and the presence of dams or other man-made structures. It is not necessarily true that discharge is likely to decrease downstream in arid regions and increase downstream in temperate regions, as this can depend on many factors including the geology of the area, vegetation, and human activity. Finally, the discharge is not typically lower in spring than during the summer. In many regions, the discharge can be higher in the spring due to snowmelt.
