Drainage pattern recognition method considering local basin shape based on graph neural network

open access: yesInternational Journal of Digital Earth, 2023
Drainage pattern recognition is crucial for geospatial understanding and hydrologic modelling. Currently, drainage pattern recognition methods employ geometric measures of overall and local features of river networks but lack measures of river basin unit

Drainage reorganization and divide migration induced by the excavation of the Ebro basin (NE Spain) [PDF]

open access: yesEarth Surface Dynamics, 2018
Intracontinental endorheic basins are key elements of source-to-sink systems as they preserve sediments eroded from the surrounding catchments. Drainage reorganization in such a basin in response to changing boundary conditions has strong implications ...

Time-varying drainage basin development and erosion on volcanic edifices [PDF]

open access: yesEarth Surface Dynamics
The erosional state of a landscape is often assessed through a series of metrics that quantify the morphology of drainage basins and divides. Such metrics have been well explored in tectonically active environments to evaluate the role of different ...
