Congratulations to everyone who presented their research at the 2017 AGU meeting in New Orleans this past week!

Laurel, Dino, and Hongxu presented on the Hydrologic Pendulum – the concept that water discharge forecasting typically uses either a physically based model or a data-driven (empirical) model. These two models sit at opposite ends of the spectrum in terms of accuracy, computational power required, and the ability to generalize the model to fit other catchments.

Developing a physically relevant model that is partially empirically derived has the potential to increase forecast accuracy and applicability across catchments. Toward this goal, the team is employing Transfer Entropy analysis and LASSO Regression, both of which have proven successful in minimizing uncertainty and selecting the most relevant features for the model.

We are nearly finished constructing our artificial vegetation setup in the Ecogeomorphology Flume! Upcoming experiments using this setup will allow us to test the effects of biofilms on sediment capture by aquatic vegetation.  Through the process we’ve collaborated with the UC Berkeley Physics Machine Shop and had the immense help of undergraduate research assistants Justin Nghiem and Roxi Shiu.

We have also conducted extensive baseline tests of particle flocculation dynamics in the flume, aided by our LISST and Justin’s data analysis skills in R.
