dcterms:description "For the Bislak River, the Philippines, this dataset contains: (i) topography and orthoimagery in 2019 and 2020; (ii) Digital Elevation Models (DEMs) of Difference; (iii) predicted depth, velocity and shear stress from HEC-RAS two-dimensional hydraulic model simulations for 10, 50 and 100 year return period flood scenarios; and (iv) calculated bedload transport for 10, 50 and 100 year return period flood scenarios. Shear stress predictions were combined with median (D50) grain size observations to compute bedload transport rates for four different river patterns (meandering, wandering, braided, deltaic). For the 50 year return period flood event, bedload transport rates were also calculated for the D16 and D84 grain size. Geomorphic change detection was used to identify geomorphic change which took place between 2014-2019 and 2019-2020. All geospatial data are in WGS 1984 UTM Zone 51N. This data was created as part of a numerical, two-dimensional hydraulic modelling investigation to predict patterns of flood inundation and bedload transport for the Bislak River Philippines under different flood scenarios (10-, 50- 100-year flood events)." ;

rdfs:label "An initial airborne LiDAR topographic survey of the Bislak River was completed in 2014, as reported by Rubio-Paringit and Parangit (2015). Subsequent airborne LiDAR topographic surveys were commissioned in 2019 and 2020 to provide repeat datasets. The Bislak DEMs were formed from a fusion of topographic data collected from different survey techniques (e.g. LiDAR, echo sounding and spectrally based depth mapping). HEC-RAS 2D software was used to predict inundation patterns (depth, velocity, shear stress). Bislak River Bedload transport rate predictions were generated using the shear stress rasters exported from HEC-RAS. Shear stress rasters were split into river morphology types (meandering, wandering, braided, deltaic)."
