Catchment Modelling Framework - A hydrological modelling toolkit
Modelling water and solute fluxes
cmf is a programming library to create hydrological models, which are highly modular and connectible to other models developed using a multiple hypotheses background. Although written in C++, its primary usage is to be compiled as an extension to other programming languages, using SWIG. Researchers can build individual models, targeting their scientific question by using the library objects like water storages, boundary conditions, fluxes and solvers. cmf uses the finite volume method to set up a wide range of models of water flow through your study area. Resulting models can range from lumped conceptual models to fully distributed darcian models and everything in between.
cmf is published as free software under GPLv3. (c) 2007-2017 by Philipp Kraft and the Institute of Landscape Ecology and Resources Management, Justus-Liebig Universität Gießen.

In the last decade, the application of classical hydrological rainfall runoff models is disputed as a valid method for understanding water transport in landscapes (eg. Beven 2002 and 2006, Seibert and McDonnell 2002, Sivapalan et al. 2003, Kirchner 2006, Tetzlaff et al. 2008), since current models lack the ability for formulation and rejection of hypotheses. Vache and McDonnell (2006) developed a framework for the rejection of model structures, where each model structure is understood as a hypothesis on runoff generation. This work is a newly developed generalized form of the Vache-McDonnell rejectionist framework, called the Catchment Modelling Framework (CMF, Kraft et al. 2011 and 2012). It is an extension to the programming language Python, written in C++, offering a toolkit for the set up of a wide range of hydrological models, following the finite volume approach by Qu and Duffy (2007). The framework exports objects to set up a network of water and solute fluxes.
Buytaert et al. (2008) and Clark et al. (2011) call also for such modular frameworks as a tool for the formulation, implementation, test and rejection of process hypotheses. Buytaert et al. (2008) demand such frameworks to be portable, accessible and modular. While hydrologists debate the theoretical application limits of runoff models for solute transport in landscapes, a growing demand of integrated landscape models for the integration of lateral transport of matter by runoff arises in interdisciplinary projects. With this background, modular hydrological frameworks need to be designed for simplified data exchange during the model runtime for interfacing the hydrology with models from different disciplines, like CMF.
CMF is portable, accessible and modular as an open source extension to the Python language and can be used for the formulation of different hypotheses. The principle of the connection of CMF with models from different disciplines is shown by Kraft et al. (2010), and Haas et al. (2012) show the relevance of tightly connected models of transport and turnover for the emission of greenhouse gases from ecosystems.
