    558558reservior lenght of 0.85m and damn depth of 0.4 m was used to verify
    559559the friction. The PVC bottom of the tank is equivalent to a friction
    560 value of 0.01. Depth sensors were placed 0.2, 0.3, 0.4, 0.5 and 0.6 m
    561 from the bed gate.

     577experiment.  This resulted in one number which represents the error
     578between tow data sets, with a lower number representing less
     579differences.  The RMSRE for no friction model was 0.380, the RMSRE for
     580the friction model with a Manning's friction value of 0.01 was
     5810.358. So for this experiment using a friction value given from a
     582standard fricition table improved the accuracy of the ANUGA
     583simulation.  {\bf Add ref to table}
