Modeling Intermittent And Perennial Headwater Stream Origins In North Carolina., Kevin Macleod

Theses and Dissertations

Low-order headwater streams, a link between the upland landscape and larger streams within a watershed, affect watershed hydrology. Yet current widely available maps inadequately depict headwater streams, underestimating channel length or omitting channels entirely. Intermittent and perennial headwater streams each provide unique habitat. Until recently, it has not been possible to accurately delineate these streams or predict channel flow durations without fieldwork. Recent advances in remote sensing may allow more accurate headwater stream mapping.

Methods for mapping intermittent and perennial headwater streams with a GIS-based modeling approach coupled with field verification were adapted, tested, and evaluated. Four models were developed …
