TUFLOW 2D Cell Size Selection: Difference between revisions

A direct rainfall approach has been used, applying rainfall directly to every cell within the model. The event hyetograph is a hypothetical 24 hour extreme event. The simulation duration has also been set to 24 hours.<br>

''Note, if you are unfamiliar with the direct rainfall modelling approach, this <u>[https://www.tuflow.com/Download/Publications/HWRS2016_Huxley_Paper.pdf Hydrology and Water Symposium]</u> paper introduces the concept.'' <br>

The following grid resolutions were used to test the impact of cell size on the assessment results and simulation time:<br>

* 10ft (3.0m) cell resolution – 5,821,533 total cell count
