The influence of lateral hydrologic connectivity on fluvial flux and ecosystem metabolism in a river-floodplain system
MetadataShow full item record
Within mountainous watersheds and river networks, low-gradient valley bottoms can function as locations of high retention and biogeochemical processing. We evaluated hydrologic dynamics, nutrient flux, and aquatic ecosystem metabolism across the snowmelt hydrograph from May – October 2015 along two river segments of the North Saint Vrain Creek, Rocky Mountain National Park, Colorado: a valley-confined channel (confined segment) and an unconfined wet valley (unconfined segment) directly downstream. We observed significant differences in water, carbon, and nutrient flux, ecosystem metabolism, and ...
