What's new – Hydrology on the new DHM/2015 model now available

Oct 31, 2015

We have added flow accumulation as well as watersheds derived from the new high-resolution (0.4 m) DHM/2015/Rain model of Denmark which includes the existing hydrological corrections. The model is currently available for Eastern Danmark. Interactive watershed queries using the watershed tool are also available.

In this area, the new model correctly resolves the stream ensuring the water takes a correct path downstream. Both partial river networks are shown here visualized on top of the DHM/2015/Rain model.

We have also added a sea-level rise computation based on the DHM/2015/Sea model.
