The R package Modelling aims to implement Dynamic Water Balance model proposed by Zhang et al. (2008) in a monthly time step. It is a tool for hydrologic modelling using the Budyko Framework and the Dynamic Water Balance Model, with DDS Tolson and Shoemaker (2007) algorithm to calibrate the model and analyze the outputs.

Installation

Currently, you can install the version under development from Github, using these commands:

install.packages("devtools")
devtools::install_github("dazamora/DWBmodelUN")

Concepts behind DWBmodelUN

Two physical laws are taken into account in Dynamic Water Balance model (DWB), mass balance and energy balance. To represent the mass conservation, DWB is based on the equilibrium of water balance shown in equation (1).
