Glacier Surface Hydrology Characterization
Melt water runoff on glaciers has a large effect on glacier dynamics. With recent technology, high resolution and accurate DEMs are available over glacier surfaces allowing the characterization of glacier surface rivers and channels.
The goals of this project are to test and adapt surface water routing algorithms on a glacier in Svalbard, and compare the results to known river locations. In particular, the low slope nature of glacier surfaces make it difficult for some algorithms to accurately represent surface water flow and the ability of the surface media to absorb water (up until saturation) should also be considered.
Eventually, the water routing algorithms will be combined with temporal models of water production and availability, and validated with supra-glacial lake filling as observed through satellite images.
