Tous test case - UCL computations2 Overview Interpreting of real data into comp. data –Representation of buildings –Upstream boundary condition –Downstream boundary condition Runs performed at UCL Analysis of the results –Water level –Discharge –Inundated area Conclusions

Tous test case - UCL computations3 The Jùcar river and Sumacárcel Tous dam Sumacárcel

Tous test case - UCL computations4 Sumacárcel Located on a hill near the Júcar

Tous test case - UCL computations5 Outflow hydrograph

Tous test case - UCL computations6 Preliminary run Localisation of inundated area in town Buildings reached by the flood -> included in the mesh Buildings not reached by the flood -> not included in the mesh First run with coarse mesh

Tous test case - UCL computations7 Meshing of the town Coarse mesh without buildings Refined mesh with buildings
