Hapi - Hydrological library for Python

Hapi is a Python package providing fast and flexible way to build Hydrological models with different spatial representations (lumped, semidistributed and conceptual distributed) using HBV96. The package is very flexible to an extent that it allows developers to change the structure of the defined conceptual model or to enter their own model, it contains two routing functions muskingum cunge, and MAXBAS triangular function. (all function has been tested and validated during a Master thesis at IHE-Delft April 2018 and the library is still under development)

Main Features

Here are just a few of the things that Hapi does well: - Easy handling of rasters data downloaded from global data and easy way to manipulate the data to arrange it to run the model - Easy calibration of the model using Harmony search method and Genetic Algorithms - flexible GIS function to process rasters interpolate values and georeference calculated discharge values to the correct place. - Different ways for considering the variability of catchment properties, lumped properties, distributed properties and hydrologic response units - Two different Ways of generating input data, from satellite data and from simple statistical methods like IDW(inverse distance weighting method) and ISDW(inverse dsquared istance weighting method) - Wide range of GIS function to process Rasters (execute some functions on a folder of rasters) like project raster, resampling, Clipping, creating a raster fom arrays, Map algebra. - Some function to plot shapefiles using and rasters using bokeh library in a web application. - Different performance criteria to measure the godness of fit of the hydrological model

Installation

Please install Hapi in a Virtual environment so that its requirements don't tamper with your system's python
**Hapi** works with Python 2.7 and 3.7 64Bit on Windows

if you are using conda

# Clone the repository. Or download the ZIP and add `-master` to the name.
git clone https://github.com/MAfarrag/HAPI

# Enter the repository
open comand prompt and type cd then the path to the repository
cd Hapi

# Create a virtualenv
open anaconda prompt and type
conda create -n Hapi_env python=3.7 anaconda 
that will create an environment named python3 that contain s Python3.7 version of Anaconda 

# Activate the env
conda activate Hapi_env

Install the dependencies

you can check libraries.io to check versions of the libraries

conda install Numpy
conda install pandas
conda install scipy
conda install fiona
conda install -c conda-forge gdal
conda install -c conda-forge rasterio

conda install geopandas

Install from Github

to install the last development to time you can install the library from github

pip install git+https://github.com/MAfarrag/HAPI

Compile

You can compile the repository after you clone it iF python is already added to your system environment variable

python setup.py install
# 
pathto_your_env\python setup.py install

pip

to install the last release you can easly use pip

pip install HAPI-Nile

conda

conda install -c mafarrag hapi

YML file

using the environment.yml file included with hapi you can create a new environment with all the dependencies installed with the latest Hapi version in the master branch

conda env create --name Hapi_env -f environment.yml
