Distributed Hydrological model
Project description
Hapi - Hydrological library for Python
Hapi is an open-source Python Framework for building raster-based conceptual distributed hydrological models using HBV96 lumped model & Muskingum routing method at a catchment scale, Hapi gives a high degree of flexibility to all components of the model (spatial discretization - cell size, temporal resolution, parameterization approaches and calibration).
Hapi
Main Features
- Modified version of HBV96 hydrological model (Bergström, 1992) with 15 parameters in case of considering snow processes, and 10 parameters without snow, in addition to 2 parameters of Muskingum routing method
- Remote sensing module to download the meteorological inputs required for the hydrologic model simulation (ECMWF)
- GIS modules to enable the modeler to fully prepare the meteorological inputs and do all the preprocessing needed to build the model (align rasters with the DEM), in addition to various methods to manipulate and convert different forms of distributed data (rasters, NetCDF, shapefiles)
- Sensitivity analysis module based on the concept of one-at-a-time OAT and analysis of the interaction among model parameters using the Sobol concept ((Rusli et al., 2015)) and a visualization
- Statistical module containing interpolation methods for generating distributed data from gauge data, some distribution for frequency analysis and Maximum likelihood method for distribution parameter estimation.
- Visualization module for animating the results of the distributed model, and the meteorological inputs
- Optimization module, for calibrating the model based on the Harmony search method
The recent version of Hapi (Hapi 1.0.1) integrates the global hydrological parameters obtained by Beck et al., (2016), to reduce model complexity and uncertainty of parameters.
Future work
- Developing a regionalization method for connection model parameters with some catchment characteristics for better model calibration.
- Developing and integrate river routing method (kinematic and diffusive wave approximation)
- Apply the model for large scale (regional/continental) cases
- Developing a DEM processing module for generating the river network at different DEM spatial resolutions.

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

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
or
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
Quick start
>>> from Hapi.run import Run
>>> from Hapi.catchment import Catchment
>>> import Hapi.hbv_bergestrom92 as HBV
