Line 101:
= Test Case 2 - Urbanised Catchment =
This test case uses a hypothetical urban model. The model encompasses the entire catchment and covers an area of approximately 21miles2 (54km2). Development within the catchment ranges from rural undeveloped in the mountainous upper catchment and dense urban development in the lower catchment. <br>
[[File:Mesh Converge Direct Rainfall Topo.png|
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>
