Data Component Use Case for Overland Flow Simulation
Tian Gan at INSTAAR - University of Colorado Boulder.
Greg Tucker at Geological Sciences - University of Colorado Boulder.
Irina Overeem at Geological Sciences - University of Colorado Boulder.
Introduction
Overland flow, particularly the infiltration-excess mechanism, is affected by the nature of water input through precipitation. This lab demonstrates how to use the CSDMS Data Components (https://csdms.colorado.edu/wiki/DataComponents) to download the topography dataset and use the Landlab components (https://landlab.readthedocs.io/) to delineate the watershed and simulate the overland flow for a study area in the Boulder County.
Classroom organization In this lab, you will learn how to use Topography and ERA5 Data Components to download terrain and precipitation datasets. You will also learn how to use the Landlab components (FlowAccumulator, ChannelProfiler, OverlandFlow) and the Landlab utility (get_watershed_mask) for watershed delineation and overland flow simulation.
Learning objectives Skills
Learn to use Data Components to download research datasets.
Learn to couple Data and Model Components for overland flow simulation.
Key concepts
Landlab
Data-Model Integration
CSDMS Data Component
Lab notes This lab can be run on the lab (for educators) and jupyter (for general use) instances of the OpenEarthscape JupyterHub: just click one of the links under the Run online using heading at the top of this page, then run the notebook in the "CSDMS" kernel.
