Modelled topographic change of the River Liang catchment, Philippines following Typhoon Mangkhut, 2018
The datasets contain maps of the total change in topography along the river Liang (Philippines) after the Typhoon Mangkhut event in September 2018. The maps have been generated using multi-phase mass model r.avaflow to simulate the change in channel and landscape.

Provenance & quality
The data was produced using multi-phase mass model r.avaflow 2.4; the model generates, individually, maps of erosion and deposition. The outputs are in the form of a numerical value indicating the depth that each cell has had for both deposition and erosion (in metres). The two maps have then been added together by a GIS software, through a “raster calculator” function, whereby a new raster has been produced with the total topographic change (in metres). Values between -0.01 and 0.01 have been filtered out to remove noise in the final map. The final output has been compared to the observed post-event topography for controlling consistency with observed values. Overall raster statistics have also been analysed to identify whether any spurious or outlier values of individual cells were observed.
