Answer to Question 1

Drainage of a lake that serves as a temporary base level will lower the base level for the part of the
stream above the lake. The stream may respond by eroding, in an attempt to reach its new base level.



Answer to Question 2

A heavy rain will increase stream volume and velocity. The channel and gradient will be temporarily
too small and low, respectively, for the increased volume. Stretches of the stream with a low gradient
will experience erosion, and stretches farther downstream may experience deposition as the gradient of
the upstream portion is adjusted (increased).
