Working with the D-Water Quality model#
The D-Water Quality module simulates the far- and mid-field water and sediment quality due to a variety of transport and water quality processes. To accommodate these, it includes several advection diffusion solvers and an extensive library of standardized process formulations with the user-selected substances. Default processes allow to simulate for instance the decay of BOD and nitrification, elementary growth of algae and nutrient cycling, exchange of substances with the atmosphere, adsorption and desorption of contaminant substances and the deposition and resuspension of particles and adsorbed substances to and from the bed.
D-Water Quality is a module of the DELWAQ software which, in combination with rainfall-runoff and hydraulic modules (e.g. wflow), and the D-Emission module, may form an integral catchment model.
In this section, we will detail the steps to run a D-Water Quality model using HydroMT and inputs from D-Emission:
Selection of substance(s) of interest and their relevant processes in surface waters
Preparing the WQ model with HydroMT (WQ model setup)
Running D-Water Quality (WQ-plugin)
