Abstract
This is an example of Geoscience Use Case 4: Height Above the Nearest Drainage (HAND) of "Improving Reproducibility of Geoscience Models with Sciunit" in the Geological Society of America publication. In this resource, there are two notebooks: 1) HANDWorkFlow.ipynb and 2) HAND_Sciunit.ipynb.
Using these two notebooks, we demonstrate the capabilities of Sciunit to encapsulate the HAND TauDEM workflow and create a Sciunit Container, and evaluate differences in HAND due to changing the contributing area threshold used to map the drainage network. During computation of the drainage network, a minimum contributing area threshold is used to identify the channel beginning. With a lower threshold value, the density of the resulting drainage network increases. Scientists running this experiment might be interested in finding out how the threshold makes a difference in the execution and result of the HAND model.
The first notebook demonstrates the general procedure to calculate HAND (Height above the Nearest Drainage) using TauDEM (https://hydrology.usu.edu/taudem/taudem5/)
Then using the second notebook we demonstrate how to create a Sciunit container for HAND Workflow and compare two Sciunit containers (5000 vs 50000 thresholds) using `diff` command.
