Installation Instructions

Download and install miniconda: https://conda.io/miniconda.html

Make sure you are using the conda-forge channel:

$ conda config --add channels conda-forge
$ conda update --yes conda python

Install gsshapy:

$ conda create -n gssha python=2
$ source activate gssha
(gssha)$ conda install --yes gsshapy jupyter

Install GSSHA: http://www.gsshawiki.com/GSSHA_Download

For Windows, add GSSHA executable to Path:

Go to: "Control Panel\System and Security\System"
Click "Advanced system settings"
Click "Environmental variables ..."
Edit the "Path" variable under "User variables" and add the path to the directory containing GSSHA (i.e. C:\Program Files\U.S. Army\gssha70)

Make sure GSSHA is on the PATH:

!gssha70









    



Parallel version of GSSHA (7.0 ) with SCE (OpenMP), 8 total threads.

Usage: gssha [-option] [inputfile]

 where -option is one of:
      -c = SCE calibration mode (input file is the calibration control file)
      -m = Monte Carlo calibration mode (input file is the calibration control file)
      -b = batch mode (input file is the batch control file)
      -s = sensitivity mode (input file is the sensitivity control file)
      -v = display version information (no project will be run)
  The c, m, b, and v commands are optional and if not present the input file is
 treated as the project file

  For the -b option, the command line should be:
      gssha -b[num_batch] gssha_inputfile

  For the -c option, the command line should be:
      gssha -c sce_inputfile

  For the -m option, the command line should be:
      gssha -m[num_batch] mc_inputfile

  For the -s option, the command line should be:
      gssha -s sen_inputfile

  For the -t option (and -tv), the command line should be:
      gssha -t[v]

  where [num_batch] is the number of batch runs to make, sce_inputfile is the SCE input file, mc_intputfile is
  the Monte Carlo input file, and sen_inputfile is the sensitivity input file.

import os
from datetime import datetime, timedelta

from gsshapy.modeling import GSSHAFramework

Setup environment:



In [2]:

    
# assuming notebook is run from examples folder
base_dir = os.getcwd()
gssha_model_name = 'philippines_example'
gssha_model_directory = os.path.join(base_dir, gssha_model_name)

Run the model:



In [3]:

    
gr = GSSHAFramework("gssha70",
                    gssha_model_directory,
                    "{0}.prj".format(gssha_model_name),
                    gssha_simulation_start=datetime(2017, 5 ,9),
                    gssha_simulation_duration=timedelta(seconds=2*60))

# http://www.gsshawiki.com/Model_Construction:Defining_a_uniform_precipitation_event
rain_intensity = 24  # mm/hr 
rain_duration = timedelta(seconds=1*60)  # 2 minutes
gr.event_manager.add_uniform_precip_event(rain_intensity,
                                          rain_duration)

gssha_event_directory = gr.run()

The gssha_event_directory is where the simulation output is stored.
