OresundHD2D basic data assimilation example
-------------------------------------------

This example shows how assimilation of two water level stations can improve the results of a 2D HD model significantly. 

A. HD model 

B. "Free5" Ensemble model without assimilation "Free run" with 5 ensemble members by perturbing the water level boundary conditions North and South

C. "EnKF10" Ensemble Kalman filter (EnKF) model with 10 ensemble members and same perturbation as in B; 2 water level stations are used for assimilation, 2 for validation

Files
* input: mesh, boundary and wind data
* obs: water level observations at four different stations in Oresund 
* plots: 3 plc files that can be opened when the setups have been run
* 3 setups 
* 3 run scripts (path to exe and parallelization can be changed here)
