QHEI - Assignment ExampleThe cover type demonstrate was overhanging vegetation and undercut wedges and sink wads exist as a major component of cover type. The cover type was extensive due to tree roots that were extensive in the water leading to an extensive undercut bank. The score for the undercut cover was calculated using the parameters that were measured from the study as follows 1+1+ 1+ 11= 14 out of a total score of 20. This is a significant score that implies a thriving vegetation a long the river that is competing with other(a) organisms present in the river for oxygen and other nutrients (Atuke 25). The amount of in stream cover type present, in the river, poses a threat to the survival of most of the organisms present in the river.The third metric was the Channel morphology that measures the quality of the stream channel that is responsible for the stability and creation of the in stream habitat. The river had a racy sinuosity with a good development of pucker and po ol complexes. The stream showed no human modifications and thus, channelization was recorded as none. The stability was recorded as high due to the extensive presence of cover type that prevents erosion. The only modification present was canopy removal. The score of the metric was calculated as 4+5+ 6+ 3= 18. This is a high score, and it implies that the river has not experienced much anthropogenic disturbance (Atuke 27).The fourth metric was the riparian zone and bank erosion. This metric records the scores the quality of the extra vegetation and the riparian buffer area. The river had a moderate riparian width on both sides with a plain vegetation of a forest and a swamp on both sides. The bank erosion on both sides was recorded as little or none due to the presence of the forest and swamp vegetation. The total score of the parameters was nine out of a possible ten. The fifth metric was the pool and riffle quality. The metric has six categories that
