Step-Pool Channel Morphology, Forcing Effects, And Geomorphic Classification In The Ozark Highlands, Se Missouri, Triston Ralland Rice
Step-Pool Channel Morphology, Forcing Effects, And Geomorphic Classification In The Ozark Highlands, Se Missouri, Triston Ralland Rice
MSU Graduate Theses
Understanding headwater streams and their morphology is inherently difficult in contrast to larger streams in downstream valleys. Geomorphic forcing can occur over short distances (<10 >m) and influence channel geometry due to geologic factors such as colluvial inputs and resistant bedrock or biologic factors such as fluvial wood inputs and tree growth in the channel. How and where these geomorphic variables effect step-pool channel characteristics is poorly understood in the Ozark Highlands. Step-pool channel form is typically controlled by gradient, substrate characteristics, and sediment supply. This study reports on a geomorphic assessment of step-pool characteristics and classifies channel form using …
Geomorphic And Land Use Controls On Headwater Channel Morphology In Mark Twain National Forest, Grace F. Roman
Geomorphic And Land Use Controls On Headwater Channel Morphology In Mark Twain National Forest, Grace F. Roman
MSU Graduate Theses
Prescribed burning has been used over the past two decades to manage forests and restore shortleaf pine-oak woodlands in Mark Twain National Forest (MTNF). While soil studies have been completed, no assessments of burning practices on small drainage channel systems have yet been done. Headwater streams may account for more than two-thirds of total stream length and are important to the maintenance of hydrologic connectivity in watersheds. This study’s focus is on understanding the relationship between frequency of forest burning and channel morphology (size, shape, and substrate) of headwater streams (km2). A combination of field measurements, geo-processing methods, …
