The evaluated models were the Bank Erosion Hazard Index (BEHI), Bank Assessment for Nonpoint Source Consequences of Sediment (BANCS), Bank Stability and Toe Erosion Model (BSTEM), and HEC River Analysis System (HEC-RAS 1D). Model-to-model assessments were conducted to quantify the impact of model selection when predicting applied stress and geomorphic change in a restored stream in North Carolina, USA. Results indicated that the mobility of the bed dictated model selection at the reach-scale. The process-based HEC-RAS 1D was needed to accurately analyze the sand-bed stream, predicting amounts of geomorphic change comparable to measured data and up to three orders of magnitude higher than those from local-scale models. At the local-scale, results indicated that the bank retreat mechanism and flow variability constrained model selection. The form-based BEHI and BANCS did not directly account for geotechnical failure nor capture severe floods, underpredicting amounts of geomorphic change by an order of magnitude when compared to the process-based BSTEM, and failing to characterize erosion potential and applied stresses after short-term morphodynamic adjustments.}, number={8}, journal={WATER}, author={Kassa, Kayla and Castro-Bolinaga, Celso and Guertault, Lucie and Fox, Garey A.

Transport dynamics are difficult to capture in traditional cyanoHAB monitoring, which can be spatially disparate and temporally discontinuous. The introduction of satellite remote sensing for cyanoHAB monitoring provides opportunities to detect where cyanoHABs occur in relation to reservoir release locations, like canal inlets. The study objectives were to assess (1) differences in reservoir cyanoHAB frequencies as determined by in situ and remotely sensed data and (2) the feasibility of using satellite imagery to identify conditions associated with release-driven cyanoHAB export. As a representative case, Lake Okeechobee and the St. Lucie Estuary (Florida, USA), which receives controlled releases from Lake Okeechobee, were examined. Both systems are impacted by cyanoHABs, and the St. Lucie Estuary experienced states of emergency for extreme cyanoHABs in 2016 and 2018. Using the European Space Agency's Sentinel-3 OLCI imagery processed with the Cyanobacteria Index (CIcyano), cyanoHAB frequencies across Lake Okeechobee from May 2016-April 2021 were compared to frequencies from in situ data. Strong agreement was observed in frequency rankings between the in situ and remotely sensed data in capturing intra-annual variability in bloom frequencies across Lake Okeechobee (Kendall's tau = 0.85, p-value = 0.0002), whereas no alignment was observed when evaluating inter-annual variation (Kendall's tau = 0, p-value = 1). Further, remotely sensed observations revealed that cyanoHABs were highly frequent near the inlet to the canal connecting Lake Okeechobee to the St. Lucie Estuary in state-of-emergency years, a pattern not evident from in situ data alone. This study demonstrates how remote sensing can complement traditional cyanoHAB monitoring to inform reservoir release decision making.}, journal={Journal of Hydrology}, author={Reynolds, Natalie and Schaeffer, Blake A. and Guertault, Lucie and Nelson, Natalie G.}, year={2023}, month={Apr} } @article{fox_guertault_castro-bolinaga_swanson_2022, title={GUIDANCE ON APPLIED PRESSURE HEADS FOR QUANTIFYING COHESIVE SOIL ERODIBILITY WITH A JET EROSION TEST (JET)}, volume={65}, ISSN={["2769-3287"]}, DOI={10.13031/ja.14884}, abstractNote={ Highlights }, number={6}, journal={JOURNAL OF THE ASABE}, author={Fox, Garey A. and Guertault, Lucie and Castro-Bolinaga, Celso and Swanson, Alexis}, year={2022}, pages={1443–1450} } @article{fox_guertault_castro-bolinaga_allen_bigham_bonelli_hunt_kassa_langendoen_porter_et al._2022, title={PERSPECTIVE: LESSONS LEARNED, CHALLENGES, AND OPPORTUNITIES IN QUANTIFYING COHESIVE SOIL ERODIBILITY WITH THE JET EROSION TEST (JET)}, volume={65}, ISSN={["2769-3287"]}, url={http://dx.doi.org/10.13031/ja.14714}, DOI={10.13031/ja.14714}, abstractNote={Highlights}, number={2}, journal={JOURNAL OF THE ASABE}, author={Fox, Garey A. and Guertault, Lucie and Castro-Bolinaga, Celso and Allen, Peter and Bigham, Kari A. and Bonelli, Stephane and Hunt, Sherry Lynn and Kassa, Kayla and Langendoen, Eddy J. and Porter, Erin and et al.}, year={2022}, pages={197–207} } @article{halihan_hager_guertault_fox_2021, title={DETECTING MACROPORE FINGERING USING TEMPORAL ELECTRICAL RESISTIVITY IMAGING}, volume={37}, ISSN={["1943-7838"]}, DOI={10.13031/aea.14294}, abstractNote={Highlights}, number={5}, journal={APPLIED ENGINEERING IN AGRICULTURE}, author={Halihan, Todd and Hager, John P. and Guertault, Lucie and Fox, Garey A.}, year={2021}, pages={861–870} } @article{heeren_guertault_mankin_2021, title={PERSPECTIVE: PREFERENTIAL FLOW IN RIPARIAN BUFFERS: CURRENT RESEARCH AND FUTURE NEEDS}, volume={64}, ISSN={["2151-0040"]}, DOI={10.13031/trans.14732}, abstractNote={Highlights}, number={6}, journal={TRANSACTIONS OF THE ASABE}, author={Heeren, Derek M. and Guertault, Lucie and Mankin, Kyle}, year={2021}, pages={1907–1911} } @article{fox_fox_guertault_2020, title={A CASE STUDY ON THE RELEVANCE OF THE JOURNAL IMPACT FACTOR}, volume={63}, ISSN={["2151-0040"]}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-85085130127&partnerID=MN8TOARS}, DOI={10.13031/trans.13756}, abstractNote={Highlights}, number={2}, journal={TRANSACTIONS OF THE ASABE}, author={Fox, G.

Streambank stabilization techniques are often implemented to reduce sediment loads from unstable streambanks. Process-based models can predict sediment yields with stabilization scenarios prior to implementation.

Both models include two soil parameters, the critical shear stress (τc) and the erodibility coefficient (kd) for the excess shear stress model and b0 and b1 for the Wilson model. Jet erosion tests (JETs) allow for in-situ determination of these parameters. JETs were completed at numerous sites along two streams in each the Illinois River and Fort Cobb Reservoir watersheds. The objectives were to use JET results from these streambank tests to investigate variability of erodibility parameters on the watershed scale and investigate longitudinal trends in streambank erodibility. The research also determined the impact of this variability on lateral retreat predicted by a process-based model using both the excess shear stress model and the Wilson model. Parameters derived from JETs were incorporated into a one-dimensional process-based model to simulate bank retreat for one stream in each watershed. Erodibility parameters varied by two to five and one to two orders of magnitude in the Illinois River watershed and Fort Cobb Reservoir watershed, respectively. Less variation was observed in predicted retreat by a process-based model compared to the input erodibility parameters. Uncalibrated erodibility parameters and simplified applied shear stress estimates failed to match observed lateral retreats suggesting the need for model calibration and/or advanced flow modeling.}, number={8}, journal={Water}, publisher={MDPI AG}, author={Enlow, Holly and Fox, Garey and Guertault, Lucie}, year={2017}, month={Aug}, pages={605} } @article{klavon_fox_guertault_langendoen_enlow_miller_khanal_2016, title={Evaluating a process-based model for use in streambank stabilization: insights on the Bank Stability and Toe Erosion Model (BSTEM)}, volume={42}, ISSN={0197-9337}, url={http://dx.doi.org/10.1002/ESP.4073}, DOI={10.1002/esp.4073}, abstractNote={Abstract}, number={1}, journal={Earth Surface Processes and Landforms}, publisher={Wiley}, author={Klavon, Kate and Fox, Garey and Guertault, Lucie and Langendoen, Eddy and Enlow, Holly and Miller, Ron and Khanal, Anish}, year={2016}, month={Dec}, pages={191–213} } @article{guertault_camenen_peteuil_paquier_faure_2016, title={One-dimensional modeling of suspended sediment dynamics in dam reservoirs}, volume={142}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-84988591480&partnerID=MN8TOARS}, DOI={10.1061/(ASCE)HY.1943-7900.0001157}, abstractNote={AbstractContinuous sedimentation of fine sediments in dam reservoirs triggers considerable economic and ecological impacts worldwide.

As the inventory of new potential dam sites is shrinking, construction of additional reservoirs is less likely compared to simultaneous flow and sediment management in existing reservoirs. One aspect of this sediment management is related to the control of upstream sediment sources. However, key research questions remain regarding upstream sediment loading rates. Highlighted in this article are research needs relative to measuring and predicting sediment transport rates and loading due to streambank and gully erosion within a watershed. For example, additional instream sediment transport and reservoir sedimentation rate measurements are needed across a range of watershed conditions, reservoir sizes, and geographical locations. More research is needed to understand the intricate linkage between upland practices and instream response. A need still exists to clarify the benefit of restoration or stabilization of a small reach within a channel system or maturing gully on total watershed sediment load. We need to better understand the intricate interactions between hydrological and erosion processes to improve prediction, location, and timing of streambank erosion and failure and gully formation. Also, improved process-based measurement and prediction techniques are needed that balance data requirements regarding cohesive soil erodibility and stability as compared to simpler topographic indices for gullies or stream classification systems.
