[MITgcm-support] Water balance problem

[Terry Chen]

Hello everyone, 
  I am trying to apply this model with NON-hydrostatic mode in a coastal region, but I meet great water loss near the offshore boundary. Thus, the model cannot represent ideal Eta result now. 
  Since in the NON-hydrostatic mode, the elevation at the boundary cannot be prescribed, so I need some way to balance the transport now. But the OBCSbalance module in the model just balances the mass transport at each time step, which actually remove some signal of tide and wind.  
  Does anyone have any idea about a better way to keep both the water balance and the signal of tide or wind? 
  Thanks a lot.
Best,
Terry
