Document Summary
*flood characteristics elevation of the water surface at any point is termed the stage of the stream flood stage: stream stage exceeds bank height crest: when the maximum stage is reached upstream floods: caused by locally intense rainstorms and dam failures flashfloods: variety of upstream floods, characterized by rapid rise of stream stage downstream floods: floods that affect large stream systems and large drainage basins result from prolonged rain over broad area or extensive regional snowmelt. *stream features caused by erosion: removal of materials by fast moving water high velocity: speed high discharge: volume in meters/second steep gradient: steepness in climatic conditions underlying geology local topography channel shape stream load vegetation local land use patterns. *stream features caused by deposition: the process of build up when a slow moving stream drops its sedimentary load loss of velocity low discharge shallow gradient climatic conditions underlying geology local topography channel shape stream load vegetation local land use patterns.
