Document Summary

Nature of change: after wildfire, a monsoon rainfall event occurred, because of fire, vegetation entered system and impacted it. Balance between stream power and sediment supply: more sediment in river system, the river doesn"t have the capacity to transport sediment. Deposits in the bottom of the river and channel changes. In urban rivers, more water than sediment; these urban rivers are constantly very flashy or erode vertically. System response: when there is a disturbance in a landscape, system will change from one state to another, agricultural setting, prior to agriculture, you may have stream that is pristine; once more. If there is a change in the system, things start to increase or decrease sediment enters, base level (bottom of the river) will change. Increases in the numbers of runoff, going from unburned to burned to salvaged. 1 l g m n o i t a r t n e c n o c.
