This dataset contains a national-scale geodatabase of stream network and river catchment characteristics in the Philippines. It presents detailed information on 128 medium- to large-sized catchments (catchment area > 250 km2). The quantitative descriptions provide context for enabling geomorphologically-informed sustainable river management. The geodatabase provides a baseline understanding of fundamental topographic characteristics in support of varied geomorphological, hydrological and geohazard susceptibility applications.

Data sets include:
1) GIS shapefiles with river catchment properties;
2) GIS shapefiles with stream network properties;
3) spreadsheets containing morphometric and topographic characteristics (n = 91);
4) example MATLAB code and topographic data to replicate the analysis for a selected catchment.

The work was supported by the Natural Environment Research Council (NERC) and Department of Science and Technology - Philippine Council for Industry, Energy and Emerging Technology Research and Development (DOST-PCIEERD) – Newton Fund grant NE/S003312/1.

Provenance & quality

The analysis used a nationwide digital elevation model (DEM) acquired in 2013 and generated through airborne Interferometric Synthetic Aperture Radar (IfSAR), with a 5 m spatial resolution and 1 m root-mean-square error vertical accuracy.
Catchment and stream network properties were calculated using TopoToolbox V2.

The web-application was designed using the ArcGIS Web AppBuilder.
