Topmodel

Introduction
The package TOPMODEL contains some functions and code snippets for hydrological data analysis with R, that may eventually make it into a properly released R package. For now, the code can be downloaded on this page and used at your own risk, without official support (although I very much welcome all feedback). The core of the package is an implementation of the venerable TOPMODEL.

Information on R, including downloads, installation and a great choice of manuals can be found on the R website. If you follow strictly the examples used below, you will be able to run TOPMODEL with a very limited R knowledge. However, R has a great potential for pre- en postprocessing of the data (including uncertainty analysis and statistics), so a more extensive knowledge of R is highly recommended!

Thanks go to Keith Beven, who wrote the original TOPMODEL in Fortran, and Huidae Cho, for the C code base (originally implemented in GRASS GIS)
