Include Advection Dispersion (AD) Water Quality
At the bottom of this dialogue is a checkbox, where you can specify whether or not to include water quality in the simulation. If checked, the data tree will expand to include water quality data items.
PT versus AD
Below the initial checkbox to include water quality, there is a radio button to select the water quality method. There are two methods for calculating water quality in MIKE SHE.
The traditional Advection dispersion method can be used to calculate the movement of multiple solutes throughout the hydrologic system, including sorption and degradation.
The particle tracking (PT) method, tracks the movement of thousands of particles that move with the water. The PT method is currently only available in the saturated zone. The PT method allows you to calcuate well field capture zones and areas of influence.
Use Current WM simulation for Water Quality
If you uncheck this check box, then you will be able to specify a different different water movement simulation as the source of the cell-by-cell flows for the water quality simulation. This allows you to use one water quality setup and calculate water quality based on several water movement scenarios. You must be careful though to not overwrite your results files from the previous water quality simulations.
