Document Summary
Geo210 lecture 6 notes: toronto island flooding, numerous agencies had to be involved, police. Increased incidents of floods since the 1960s: 1993, red river flood is well known. Facilities disperse their waste very close to the rivers when waster-related laws were lax. Leads to more damage: discharge, the total volume of water which flows past a point, measured in cubic metres/second, q = wdv, w = width, d = depth, v = velocity. Fastest flowing river in the world is the amazon river according to this equation: 180000 cubic metres/second. Followed closely by the congo river in africa: 41000 cubic metres/second, yangtze river in china, 34000 cubic metres/second, three gorges dam controls the stream. St. lawrence river in canada: 14000 cubic metres/second. Stream channel: processes of stream erosion, stream erosion. Stream capacity: measures in watts/cubic metres, depends on several factors (proportional, velocity, dimension. Winter 2018: depth, width, hydraulic radius, gradient, competence of a river, ability to transport sediments.
