Abstract

Defining and mapping the upstream point at which a first order channel begins, the channel head, is important for the quantification of drainage networks. Their positions have implications to drainage density and total channel length, which are important for quantification of the transport of water, sediment, and other constituents through watershed drainage networks. Detailed mapping of first order channels and their upper termini, have not yet been accurately delineated in many locations of coastal Maine. In this study we conducted field and remote mapping of Kebo Brook Watershed, a ~1.5km2 post-glacial basin situated in a north-south trending valley on the eastern side of Acadia National Park. We mapped watershed settings defined by vegetation, permeability, soil composition, surficial deposits, slope, and landscape features such as glacial moraines. We also delineated headwater streams throughout the watershed. These data were used to identify associations between watershed settings and first order channel characteristics. Stream network analyses such as these will help improve future modeling and management activities in the post-glacial granitic landscapes of the northeastern coastal region.
