Investigaing Mechansims of Hydraulic Conductivity Transience in Sandy Streambeds
  • Presentation Type: Thesis Defense
  • Date: 3/30/2018
  • Abstract:

    This research utilized a time series of hydraulic, geophysical, and sedimentological data to differendate between streambed processes that give rise to hydraulic conductivity (K) heterogeneity in streambed sediments. Most research on streambed K has focused on characterizing spatial heterogeneity, this study is unique in its focus on temporal variability and for integrating methods from multiple disciplines. This work has potential implications for hyporheic processes, as well as more traditional applications in hydrology and geomorphology. Permeameters and slug tests were used to densely sample K in a grid on the Loup River in East-central Nebraska between June and August of 2017. K did not change significantly between June and July, but did between July and August in response to an anthropogenic high flow event. This study's results suggest that depositional and erosional processes may play a less significant role in shaping streambed K heterogeneity than has been suggested by some researchers.
