Estimating Bedload Transport in Gravel-Bedded Rivers, MA 2021

Welcome Guest ( Sign In )

Overview

This lidar dataset was collected as part of an NCALM Seed grant for Jordan Fields at Dartmouth College. The dataset collected provided field validation of the virtual velocity approach for estimating bedload transport in gravel-bedded rivers. The study area is located near North Adams, MA and covers approximately 3.6 km^2.
