Validation of this model was carried out by comparing results 499 from ANUGA against experimental results from flume wave tanks. The 500 experiments were carried out at the Gordon McKay Hydraulics Laboratory 501 at St Lucia, University of Queensland. 502 503 488 504 % Validation UQ flume 489 505 % at X:\anuga_validation\uq_flume_2007 … … 499 515 \centerline{\includegraphics[width=4in]{uq-flume-velocity.eps}} 500 516 \caption{Comparison of wave tank and \ANUGA{} water velocity at .45 m 501 from the gate}\label{fig:uq-flume- depth}517 from the gate}\label{fig:uq-flume-velocity} 502 518 \end{figure} 503 519 504 520 Flume data from the University of Queensland has also been used for 505 validating \ANUGA{}. The experiments were carried out at the Gordon 506 McKay Hydraulics Laboratory at St Lucia. The Flume was set up for 507 Dam-break experiments, having a water reservior at one end. The flume 508 was glass-sided, 3m long, 0.4m in wide, and 0.4m deep (check 509 depth), with a PVC bottom. The reservoir in the flume was 0.75m long. 510 For this experiment the reservoir water was 0.2m deep. At time zero 511 the reservoir gate is opened and the water flows into the other side 512 of the flume. 513 514 515 % Validation UQ friction 516 % at X:\anuga_validation\uq_friction_2007 517 % run run_dam.py to create sww file and .csv files 518 % run plot.py to create graphs, and move them here 519 \begin{figure}[htbp] 520 \centerline{\includegraphics[width=4in]{uq-friction-depth.eps}} 521 \caption{Comparison of wave tank and \ANUGA{} water height at .4 m 522 from the gate, simulated using a Mannings friction of 0.0 and 0.1.}\label{fig:uq-friction-depth} 523 \end{figure} 521 validating the water height and velocity predicted by \ANUGA{}. The 522 Flume was set up for Dam-break experiments, having a water reservior 523 at one end. The flume was glass-sided, 3m long, 0.4m in wide, and 524 0.4m deep, with a PVC bottom. The reservoir in the flume was 0.75m 525 long. For this experiment the reservoir water was 0.2m deep. At time 526 zero the reservoir gate is opened and the water flows into the other 527 side of the flume. To accurately model the bed surface a Manning's 528 friction value of 0.01, representing PVC was used. 529 530 % Neale, L.C. and R.E. Price.

Proc 90SA3, ASCE. 532 % pp. 109-129. 1964. 533 534 Acoustic displacement sensors that produced a voltage that changed 535 with the water depth was positioned 0.4m from the reservoir gate. The 536 water velocity was measured with an Acoustic Doppler Velocimeter 0.45m 537 from the reservoir gate. This sensor only produced reliable results 4 538 seconds after the reservoir gate opened, due to limitations of the sensor. 539 540 Figure~\ref{fig:uq-flume-depth} show that ANUGA predicts the actual 541 water depth very well, with the exception of the fluid tip-region. The 542 water velocity is also predicted accurately. 543 524 544 525 545 \section{Conclusions}
