Animation of the spatial density of river runoff water. Although there are the same number of elements from each river, the density plots are weighted with the actual runoff at time of seeding. This weighting can be done/changed afterwards without needing to redo the simulation. The calculated density fields will be stored/cached in the analysis file for later re-use, as their calculation may be time consuming for huge output files. Note that other analysis/plotting methods are not yet adapted to datasets opened lazily with open_xarray

runoff_river1 = np.abs(np.cos(np.arange(number)*2*np.pi/(number)))  # Impose a temporal variation of runoff
runoff_river2 = 10*runoff_river1  # Let river 2 have 10 times as large runoff as river 1
runoff = np.concatenate((runoff_river1, runoff_river2))
