runoff channels on mars are equivalent to dry river beds, they show evidence that water flow and currents once existed, the river beds on mars are predicted to be roughly 4 billion years old.

What are outflow channels on mars?

outflow channels are channels which were created during enormous flash floods on mars. after the time of free flowing water, when run off channels were formed, the climate on mars became very cold and much of the water was frozen into ice caps. about one billion years after this volcanoes became active on the planet and melted much of the ice caps into water, this caused huge flash floods. when the volcanism ended, the water refroze into the conditions it is in today.

What is snowmelt runoff?

Runoff is water that flows over the ground surface. Snowmelt runoff is runoff from melting snow.

How can building towns make flood worse?

The hard, impermeable surfaces in cities and towns lead to increased runoff and less water being absorbed into the ground. Too much runoff can cause flooding directly. The increased runoff also means that rainwater enters streams and rivers more quickly, making it more likely that stream channels will overflow.

What is storm flow in geographical terms?

Stormflow is the storm runoff generation. These flows occur less frequently and rare, but can have influence on the behavior and appearance of channels for years or decades.
