HYPE documentation


This documentation concerns the hydrological model HYPE. HYPE is a semi-distributed hydrological model for water and water quality. It simulates water and nutrient concentrations in the landscape at the catchment scale. HYPE was originally developed at the Swedish Meteorological and Hydrological Institute (SMHI) with focus on:

HYPE Open Source Community

HYPE OSC is an open source initiative under the Lesser GNU Public License taken by SMHI to strengthen international collaboration in hydrological modelling and hydrological data prodution.

The main objective of HYPE OSC is to provide public access to a state of-the-art operational hydrological model while encouraging hydrologic and programming expertise from different parts of the world to contribute to model improvement. The hypothesis is that more brains and more testing will result in better models and better code. An open source community will ease the sharing and enable ensemble modelling by free access to source codes. Our aim is to provide a platform for international cooperation, networking, knowledge exchange and collective sourcecode development.

HYPE OSC offers the present HYPE model source code to start with. The code is transparent and modularized. This means that the code is easy to understand and can be changed and learnt from and allows for parallel development of independent components. New versions of the main code is uploaded frequently.

The code is written in Fortran 90, but some later features may have been used. The code compiles with both Intel compiler ifort and with the GNU fortran compiler gfortran. These compilers are available and tested on both Windows and Linux platforms. Other compilers/platforms has not been tested.
