#Streamflow Prediction Tool App tethysapp-erfp_tool

This app is created to run in the Teyths Platform programming environment. See: https://github.com/CI-WATER/tethys and http://docs.tethys.ci-water.org

This app requires you to have the ECMWF-RAPID preprocessing completed separately. See: https://github.com/CI-WATER/erfp_data_process_ubuntu_aws

##Prerequisites:

• Tethys Platform (CKAN, PostgresQL, GeoServer)
• netCDF4-python (Python package)

###Install netCDF4-python on Ubuntu:

$ sudo apt-get install python-dev zlib1g-dev libhdf5-serial-dev libnetcdf-dev
$ . /usr/lib/tethys/bin/activate
$ pip install numpy netCDF4

###Install netCDF4-python on OSX: Note: this app was desgined and tested in Ubuntu

$ brew install homebrew/science/netcdf
$ . /usr/lib/tethys/bin/activate
$ pip install numpy netCDF4

###Install netCDF4-python on Redhat: Note: this app was desgined and tested in Ubuntu

$ yum install netcdf4-python hdf5-devel netcdf-devel
$ . /usr/lib/tethys/bin/activate
$ pip install numpy netCDF4

##Installation: Clone the app into the directory you want:

$ git clone https://github.com/CI-WATER/tethysapp-erfp_tool.git
$ cd tethysapp-erfp_tool
$ git submodule init
$ git submodule update

Then install the app in Tethys Platform.

###Installation for App Development:

$ . /usr/lib/tethys/bin/activate
$ cd tethysapp-erfp_tool
$ python setup.py develop
$ tethys syncstores erfp_tool

###Installation for Production:

$ . /usr/lib/tethys/bin/activate
$ cd tethysapp-erfp_tool
$ python setup.py install
$ tethys syncstores erfp_tool
$ tethys manage collectstatic

Restart the Apache Server: See: http://docs.tethys.ci-water.org/en/1.1.0/production/installation.html#enable-site-and-restart-apache

##Updating the App: Update the local repository and Tethys Platform instance.

$ . /usr/lib/tethys/bin/activate
$ cd tethysapp-erfp_tool
$ git pull
$ git submodule update

Reset the database if changes are made to the database (this will delete your old database and regenerate a new app instance id):

$ tethys syncstores erfp_tool -r

Restart the Apache Server: See: http://tethys-platform.readthedocs.org/en/1.0.0/production.html#enable-site-and-restart-apache

#Troubleshooting If you see this error: ImportError: No module named packages.urllib3.poolmanager
