What is it about?

We used a nationwide digital elevation model (DEM) to calculate stream network and river catchment properties for 128 medium- to large-sized catchments in the Philippines. The systematic assessment shows the diversity and distinctiveness of Philippine river systems. We displayed the results in an interactive web-application that enables anyone to freely access, explore and download the data.

Why is it important?

Effective river management requires an understanding of the resource that is being managed. The national-scale geodatabase provides place-based understandings that contextualize Philippine river systems. The geodatabase provides baseline data in support of varied geomorphological, hydrological, water resource and natural hazard management applications.


I hope that our national-scale geodatabase can support of sustainable river management activities in the Philippines, helping achieve catchment-scale visions that recognise river diversity and embed fluvial geomorphology into policy and practice.
