Measuring Hydrologic and Biogeochemical Processes in an Intermittent Stream, ID 2023

Welcome Guest   ( Sign In )

Overview

NCALM logo This lidar dataset was collected as part of an NCALM Seed grant for Michelle Sclafani at Idaho State University. This dataset was collected to evaluate the role of hillslope topography, channel morphology, and riparian vegetation density canopy cover in patterning of longitudinal stream wetting and biogeochemical processing in an intermittent stream. The dataset was collected over Johnston Draw, Idaho.
