Flaps on take-off and landing

No. It's like increasing the angle of attack on a thicker wing
section which stalls at a lower speed.

Ground effect is completely different:

http://en.wikipedia.org/wiki/Ground_effect
The term Ground effect (or Wing In Ground effect) refers to the
increase in lift experienced by an aircraft as it approaches
within roughly 1/4 of a wingpspan's length of the ground or other
level surface (such as the sea)

But if you are hopping over small obstacles near the runway, you're
probably very close to being within the distance influenced by ground
effect, aren't you?
