Software Instructions: Online and Personal Computer

To open interactive Jupyter Notebooks with Binder JupyterHub server. You will be connected to a virtual machine with the software environment required to execute the models.

Online Modeling Instructions

To open interactive Jupyter Notebooks with the CUAHSI JupyterHub server, go to the upper right corner of the resource page and click on 'Open With'. Select CUAHSI JupyterHub. You will be connected to a virtual machine with the software environment required to execute the models.

Notebook 1: Educate by exploring rainfall driven hydrographs with Landlab: Explore_routing_tutorial.ipynb

Notebook 2: Replicate an experiment on a watershed subset within regional Landlab landslide model to explore fire impacts. The resource was originally derived from a reproducible demonstration of the landslide modeling results from: Strauch, R., Istanbulluoglu, E., Nudurupati, S. S., Bandaragoda, C., Gasparini, N. M., and Tucker, G. E.: (2018) A hydro-climatological approach to predicting regional landslide probability using Landlab, Earth Surf. Dynam. Discuss., https://doi.org/10.5194/esurf-6-49-2018: Replicate_landslide_model_for_fire.ipynb

Notebook 3: Reuse ecohydrology model for exploring climate scenarios. The gridded meteorology forcings are pre-processed in the Notebook in NewMexico_observatory_gridmet.ipynb: Reuse_ecohydrology_observatory.ipynb

Personal Computer Installation Instructions

Packages

The notebooks included in this resource require the following Python packages:

landlab 1.6.0 geopandas 0.5.0 dask 1.2.0 ogh 0.2.1 matlplotlib 3.0.3 pandas 0.24.2 ffmpeg 4.1.3 hs_restclient 1.3.3

To ensure that you have the correct packages and versions, run the following command(s) inside a Python terminal:

$ conda list

or

$ pip list

Creating a Working Environment

We recommend using Anaconda to create a fresh Python environment with all dependencies installed. After installing Anaconda, simply run the commands below with your desired environment name in place of MY_ENVIRONMENT_NAME:

conda create -n MY_ENVIRONMENT_NAME --file requirements.txt

activate the environment and start a jupyter server

source activate MY_ENVIRONMENT_NAME jupyter notebook

Debugging a Working Environment

Are you getting errors? Here are some suggested steps. If you still have issues, email help@cuahsi.org or reach out to us (comment on this resource or see emails in HydroShare profiles) and we will invite you to the HydroShare Slack #landlab channel.

Bug: PackagesNotFound

PackagesNotFoundError: The following packages are not available from current channels.

Reduce the number of packages that were not available by running the following command

conda config --append channels conda-forge

Bug: Conda vs.Pip Install

If you get errors for a few packages, remove them from the requirements.txt file until you successfully created the conda environment.

conda create -n MY_ENVIRONMENT_NAME --file requirements.txt

Any packages that didn't get installed during creation of conda environment can be pip installed separately in the newly created conda environment. for example:

pip install hs-restclient==1.3.3
