It is recommended that grass and [[enhanced grass swales]] be modelled using the 'Swale' element in the TTT. A 'swale' has to connect two existing elements within the TTT

For detailed scenarios of enhanced swales, the weir element can be incorporated for checkdams. At this time the weirs are seperate elements which must be placed within several distinct swales along a single reach.

At this time weirs are separate elements, that must be placed within several distinct swales along a single reach.

[[Bioswales]] or dry swales, which have amended filter media, should be modelled as [[Bioretention: TTT|bioretention cells]].

The alternative is to use the 'enhanced swale' within the LID toolbox, but this incorporates fewer design parameters (and also excludes check dams).
