Analysis of hydrological oriented time series.

Hydropy

Analysis of hydrological oriented time series. Basically, the package adds domain-specific functionalities to Pandas DataFrames, while keeping the power of it.

Examples are:

# Recession periods in June 2011:
myflowserie.get_year('2011').get_month("Jun").get_recess()

# Peak values above 90th percentile for station LS06_347 in july 2010:
myflowserie['LS06_347'].get_year('2010').get_month("Jul").get_highpeaks(150, above_percentile=0.9)

# Select 3 storms out of the series
storms = myflowserie.derive_storms(raindata['P06_014'], 'LS06_347', number_of_storms=3, drywindow=96, makeplot=True)

A more extended tutorial/introduction is provided in a ipython notebook. See the output at http://nbviewer.ipython.org/github/stijnvanhoey/hydropy/blob/master/hydropy_tutorial.ipynb

We acknowledge the Flemish Environmental Agency (VMM) for the data used in the tutorial. It can be downloaded from http://www.waterinfo.be/.

To install this, git clone the repo and then install it by:

python setup.py install
