GEOG 203 Chapter Notes - Chapter 6-7: Urban Heat Island, Green Roof, Surface Energy
Document Summary
Stream discharge: discharge flow vol per unit of time, q=wdv, q= discharge, q increased downstream direction, other variables increase, w- channel width, d= channel depth, v= stream velocity. Dam-controlled discharge and sediment redistribution: ri(cid:448)er"s sedi(cid:373)e(cid:374)t supply (cid:449)as cut off starve the river. Exotic streams: high potential evapotranspiration rates in an arid region can cause discharge to decrease with distance downstream, this is when there is allot of moisture. Flow and channel characteristics: flow characteristics are seen as a cross sectional view, flow becomes turbulent in shallow streams, meandering stream. Stream deposition: weathering and transportation cause streams to meander and migrate downstream through the landscape, flood plains flat, low-lying area flaking many stream. It is formed when the river overflows its channel during times of high low: flood plains are inundated during floods. Urban landscape produces the temperature readers of this book. Surface energy characteristics are similar to desert locations.
