  • This study explores the origin of 15 small coastal watersheds (SCWs) confined entirely to the lower Coastal Plain, which lie between the watersheds of the major rivers flowing across the Texas Coastal Plain. The relationship between SCWs and larger
  • rivers was examined to determine whether the SCWs developed independently of the larger rivers, or became separated from them due to drowning of confluences by sea level rise or watershed fragmentation avulsions. None of the SCWs show evidence
  • occur, involving the entire reach from the avulsion site to the river mouth. Second, hydraulic connection between the newer and older channels must be lost. Third, the abandoned channel must receive sufficient tributary input or upland run-off
  • Downstream geomorphic variation and local bedrock influence of a steep transitional river : Blue Ridge to Piedmont, South Carolina
  • Spatial patterns in geomorphic variations are examined in a river transition from the Southern Blue Ridge to the Piedmont physiographic regions. Downstream hydraulic geometry (DHG), fining of bed material, and changes in reach-scale channel-bed
