The sediment trap. consists of a <br />series of three drums (0.5 m3 total capacity) which collect runoff and sedi- <br />ment from a 92 m2 headwater portion of the intense-bum watershed, Burnt <br />Mesa (fig, 3). <br /> <br />Another technique for monitoring geomorphic processe....s and landscape chan- <br />ges in the devegetated basins is terrestrial photography (Malde, 1973). In the <br />present study, the camera has been used in two ways: (1) as a portable and <br />visual note-taking method. and .'(2) --fQr repetitive photography at 5 permanent <br />camera stations to monitor changes over extended time periods. <br /> <br />SEDIMENT SOURCES <br /> <br />The lengths and types of surface runoff influence the location of sediment <br />supply in the devegetated watershed. Extensive rill systems develop on the <br /> <br />"''''r." <br />
