Abstract. The Arctic regions experience intense transformations, such that efficient methods are needed to monitor and understand Arctic
landscape changes in response to climate warming and low-frequency high-magnitude events. One example of such events,
capable of causing serious landscape changes, is glacier lake outburst floods. On 6 August 2017, a flood event related to glacial 
lake outburst affected the Zackenberg River (NE Greenland). Here, we provided a very high-resolution dataset representing
unique time-series of data captured immediately before (5 August 2017), during (6 August 2017), and after (8 August 2017)
the flood. Our dataset covers a 2.1-km-long distal section of the Zackenberg River. The available files comprise: (1)
unprocessed images captured using an unmanned aerial vehicle (UAV): https://doi.org/10.5281/zenodo.4495282 (Tomczyk
and Ewertowski, 2021a); and (2) results of structure-from-motion (SfM) processing (orthomosaics, digital elevation models, 
and hillshade models in a raster format), uncertainty assessments (precision maps) and effects of geomorphological mapping
in vector formats: https://doi.org/10.5281/zenodo.4498296 (Tomczyk and Ewertowski, 2021b). Potential applications of the
presented dataset include: (1) assessment and quantification of landscape changes as an immediate result of glacier lake
outburst flood; (2) long-term monitoring of high-Arctic river valley development (in conjunction with other datasets); (3)
establishing a baseline for quantification of geomorphological impacts of future glacier lake outburst floods; (4) assessment of 
geohazards related to bank erosion and debris flow development (hazards for research station infrastructure – station buildings
and bridge); (5) monitoring of permafrost degradation; and (6) modelling flood impacts on river ecosystem, transport capacity,
and channel stability.

Short summary
We collected detailed (cm-scale) topographical data to illustrate how a single flood event can modify river landscape in the high-Arctic setting of Zackenberg Valley, NE Greenland. The studied flood was a result of an outburst from a glacier-dammed lake. We used drones to capture images immediately before, during, and after the flood for the 2-km-long section of the river. Data can be used for monitoring and modelling of flood events and assessment of geohazards for Zackenberg Research Station.
