Version 4.5 of the MGB was developed for use with the most stable version of the QGIS software available (3.4.14 ‘Madeira’). The main change in this version is related to the interaction between flooded area and soil when using flow propagation by the inertial model. We have included an infiltration flow to the soil of the area that is flooded, in addition, part of the water balance (precipitation, evaporation and dsup) has been modified to take into account the flooded fraction in the mini-basin. It is possible that the values of the calibrable parameters of versions prior to MGB 4.1 have to be modified for the simulation with MGB 4.5.
ATTENTION: we changed the order of the daily weather reading file! The order of the columns should be 1) Temperature, 2) Relative humidity, 3) Hours of Sun (SunHours), 4) Wind (Wind), 5) Atmospheric Pressure (AtmPres). Same order as the lines in the medias.cli input file.
Regarding the IPH HydroTools plugin, it also works for QGIS version 3.4.14 ‘Madeira’.

The MGB model is a plugin that is added to Quantum GIS after it is already installed on the computer. To install the plugin on Quantum GIS, download the plugin from the link below, then unzip the file with the plugin so that you have a folder called “MGB” and inside it all the MGB plugin files.
Installing the MGB and IPH Hydro Tools plugins
1º – Compress the plugin folder to “zip” format.
2° – With QGIS open, access the “Add-ons” tab and select “Manage and Install Add-ons”.
3° – Select the option “Install from ZIP”.
4° – Select the ZIP file of the desired plugin and click on “Install Add-on”.
5° – Installed! It will be available at the top of QGIS along with other extensions. Otherwise, go back to “Manage and Install Add-ons” and select the “Installed” tab and make sure the box next to it is selected.
