Summary
This dataset contains geomorphic metrics across 32 cross-sections at four catchments within the Clarksburg Special Protection Area in Montgomery County, Maryland. These data were derived from raw cross-sectional data collected by the Montgomery County, Maryland Department of Environmental Protection. Geomorphic metrics include channel area, bed location, channel depth, channel width, and bank movement for each bank. The catchment types included in this assessment were a majority agricultural catchment which began to be developed in 2016, a forested "control" catchment, and two urbanizing catchments with a high density of stormwater best management practices, in which cross-sectional surveys were collected pre-, during, and post-construction.

These data were used to evaluate the impact of land use change on local stream morphology over the course of more than a decade. The geomorphic metrics included in this dataset can be used to contribute to the evaluation of stream changes over multiple years and across different landscapes but in a similar geographic area.
