An Implementation of Dynamic TOPMODEL Hydrological Model in R

An R implementation and enhancement of the Dynamic TOPMODEL semi-distributed hydrological model originally proposed by Beven and Freer (2001) . The 'dynatop' package implements code for simulating models which can be created using the 'dynatopGIS' package.

dynatop - Maintainance branch for v0.2.* of dynatop

This R package contains the core code to perform a dynamic TOPMODEL simulation. A related package for processing GIS data to set up dynamic TOPMODEL implementations can be found here.

These two packages are intended as successors to the original Dynamic TOPMODEL implementation in R; the dynatopmodel package. Currently (as a design choice) not all the features of the original package are implemented.

If there is a feature or improvement you want or you experience problems please raise an issue (or better still submit a pull request with alterations or fixes!) rather than contact the maintainers directly in the first instance.

Over time there have been numerous variations on and applications of the R versions of dynamic TOPMODEL, selected references can be found in the Selected References vignette or here

Thanks goes to:

• Peter Metcalfe who developed the original port of Dynamic TOPMODEL to R during his PhD sponsored by the JBA Trust.
• The NERC Q-NFM project (NE/R004722/1) at Lancaster University for supporting this update to dynatop.
• The original developers of Dynamic TOPMODEL, Keith Beven and Jim Freer, who contributed to the original R port of Dynamic TOPMODEL.

Using the code

Alongside the packages available on CRAN the latest development version can be installed from the git repository from within R using the devtools package:

devtools::install_github("waternumbers/dynatop")

Prebuild packages of the development version (which may be ahead of CRAN) are available from the r-universe
