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: 1) encapsulating HAND TauDEM workflows and creating a Sciunit Container, and 2) `diff` command to compare the results of drainage network according to the contributing area threshold. 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.

How to run the Hand Workflow and Sciunit

This Readme file provides the users with the step-by-step guide to successfully run the two developed notebooks.
The steps, in the order they need to be taken, are explained in what follows.

STEP_0 Preliminary step

In this step the modellers make sure that they have access to the content files of the resource and required compute platform.
- In order to be able to run the three Jupyter notebooks, modelers need to first have a HydroShare account.
- If the modeler already does not have access to CyberGIS-Jupyter for Water (CJW), they need to ask to get access to it at the CyberGIS-Jupyter for Water platform

Important notes before running the notebooks:
- To run each notebook:
1. Click the OpenWith button in the upper-right corner of this HydroShare resource webpage;
2. Select "CyberGIS-Jupyter for Water";
3. Open the notebook and follow instructions;

STEP_1 Execute HANDWorkFlow using HANDWorkFlow.ipynb

The first notebook demonstrates the general procedure to calculate HAND (Height above the Nearest Drainage) using TauDEM (https://hydrology.usu.edu/taudem/taudem5/).

STEP_2 Execute Sciunit using HAND_Sciunit.ipynb

This demonstrate how to create a Sciunit container for HAND Workflow and compare two Sciunit containers (5000 vs 50000 thresholds) using diff command.
