Document Summary
The risk has increased due to the amount of new buildings on floodplains. There have been flooding in toronto (ex// steeles ave. w & finch ave. w. ) and dvp was shut down due to the flood in toronto, august 2005. Hydrologic cycle: what it shows is the cyclical even. Watershed = surface area of all the water that falls into that surface and drains into the place between mountains and coastal plain. At the top of the watershed we get river valley. And at the bottom of the watershed we get floodplain. Floodplain = the stretch of the river channel and all the sand and sediments fall into that area. Base level = lowest level the river can erode to and then it just goes into the ocean. Stream in balance with its surroundings is called a graded stream. Stream balances erosion, sediment, transport, and deposition. Erosion by streams has shaped the land surface worldwide.
