Abstract:

A new grid coarsening strategy, denoted as hydrography-driven coarsening, is developed in the present study. The hydrography-driven coarsening is designed to retain the essential hydrographic features of valleys and channels observed in high-resolution digital elevation models: (1) depressions are filled in the considered high-resolution ...More
