Data Component Use Case for Overland Flow Simulation

This resource includes a Jupyter notebook to demonstrate how to use the CSDMS Data Component (https://csdms.colorado.edu/wiki/DataComponents) to download the topography dataset and use the Landlab component (https://landlab.readthedocs.io/en/master/) to delineate the watershed and simulate the overland flow for a study area in the Boulder County.

HydroShare users can run the Jupyter Notebook (overland_flow.ipynb) directly through the \"CUAHSI JupyterHub\" web app with the following steps:
- For the new user of the CUAHSI JupyterHub, please first make a request to join the \"CUAHSI Could Computing Group\" (https://www.hydroshare.org/group/156). After approval, the user will gain access to launch the CUAHSI JupyterHub.
- Click on the \"Open with\" button. (on the top right corner of the page)
- Select \"CUAHSI JupyterHub\"
- Select \"CSDMS Workbench\" server option. (Make sure to select the right server option. Otherwise, the notebook won't run correctly.)

If you encounter \"Kernel Restarting\" error when running this notebook on CUAHSI JupyterHub, select \"Kernel\" -> “Shut Down All Kernels\" -> \"Restart Kernel and Clear All Outputs\" and rerun this notebook.

Please go to https://github.com/gantian127/overlandflow_usecase to learn how to run this notebook on local PC or CSDMS JupyterHub.

本资源包含一份Jupyter笔记本（Jupyter Notebook），用于演示如何借助CSDMS数据组件（CSDMS Data Component，https://csdms.colorado.edu/wiki/DataComponents）下载地形数据集，并结合Landlab组件（Landlab component，https://landlab.readthedocs.io/en/master/）对博尔德县某研究区域开展流域划分与坡面径流模拟。

HydroShare平台用户可通过"CUAHSI JupyterHub"网页应用直接运行该Jupyter笔记本（overland_flow.ipynb），具体操作步骤如下：
- 若为CUAHSI JupyterHub新用户，请先申请加入"CUAHSI云计算工作组（CUAHSI Could Computing Group）"（https://www.hydroshare.org/group/156），获批后即可获得启动CUAHSI JupyterHub的权限。
- 点击页面右上角的"Open with"按钮。
- 选择"CUAHSI JupyterHub"。
- 选择"CSDMS Workbench"服务器选项（请务必选择正确的服务器选项，否则将无法正常运行该笔记本）。

若在CUAHSI JupyterHub上运行该笔记本时遇到"Kernel Restarting"（内核重启中）报错，请依次选择"Kernel"→"Shut Down All Kernels"→"Restart Kernel and Clear All Outputs"，随后重新运行该笔记本。
