1) What would happen if evaporation exceeded precipitation over the continents and oceans? The ocean would eventually dry up.

2) Find a map of our River Basin in Madison County OR draw a hand drawn map of the tributaries that empty into the French Broad River?



3) How does the development of urban areas along streams and rivers affect discharge during periods of heavy rainfall? On the side of a river, that hasn't been urbanizied, there's lots of vegetation which slows down rain water and allows it to soak into the earth of the riverbed. When humans develope around streams and rivers, it usually is concrete or asphalt and this doesn't allow the soil to absorb the water. The water just ends up evaporating and not entering the river.

1) Headwaters of French Broad? -Tributaries The headwaters are used for many activities but mostly canoeing, kayaking, and tubing.

2) Mouth of French Broad? Flows into the Tennessee River at Knoxville, Tenn.

3) Satellite view of French Broad?

15)Explain how the uplift of the land area that contains a river at its base level affects the river's channel. Example: The many meanders of the Kentucky River show that it was a mature stream with little relief. Uplift of the central Kentucky area //rejuvenated// the stream, causing it to cut a deep canyon, but preserving the meanders that indicate the stream existed prior to the uplift.

Lack of maintence work such as completing repairs. New Orleans is below sea level. The 2010 Pakistan floods began in late July 2010 following heavy monsoon rains in the Khyber Pakhtunkhwa, Sindh, Punjab and Balochistan regions of Pakistan and affected the Indus River basin. At one point, approximately one-fifth of Pakistan's total land area was underwater. In 1998 there was bad flooding raising some rivers up to 17 inches.
