-\subsection{1D flume tank to verify friction}
-\label{sec:friction}
-The same tilting flume tank was used to validate stage and velocity
-was used to validate the ANUGA friction model. A ground slope of 1:20,
-reservior lenght of 0.85m and damn depth of 0.4 m was used to verify
-the friction. The PVC bottom of the tank is equivalent to a friction
-value of 0.01.  {\bf Add ref } Depth sensors were placed 0.2, 0.3,
-0.4, 0.5 and 0.6 m from the bed gate.
-
- 
-As described in the model equations in ~\ref{sec:model}, the bed
-friction is modelled using the Manning's model. {\bf Add the formula}
-Validation of this model was carried out by comparing results
-from ANUGA against experimental results from flume wave tanks. 
- 
-This experiment was simulated twice by ANUGA: without using the
-friction model {\bf Duncan says: It really used the friction model, with a
-value of 0.0, representing no friction model.  Is it ok to say
-'without using the model?'} and using the friction model with a
-Manning's friction value of 0.01.  The results from both of these
-simulations were compared against the experimental flume tank results
-using the Root Mean Square Relative Error (RMSRE). The RMSRE was
-summed over all of the depth sensors, for the first 30 seconds of the
-experiment.  This resulted in one number which represents the error
-between tow data sets, with a lower number representing less
-differences.  The RMSRE for no friction model was 0.380, the RMSRE for
-the friction model with a Manning's friction value of 0.01 was
-0.358. So for this experiment using a friction value given from a
-standard fricition table improved the accuracy of the ANUGA
-simulation.  {\bf Add ref to table}
