Drainage basins delineate Earth's land surface into individual water collection units. Basin
shape and river sinuosity determine water and sediment dynamics, affecting landscape …

The geographic distribution of streams and rivers drives a multitude of patterns and
processes in hydrology, geomorphology, geography, and ecology. Therefore, a …

Topographic metrics are designed to quantify scale‐relevant relationships between
geometric properties of landscapes to reveal the processes shaping them. They have long …

The global availability of Digital Elevation Models (DEMs) has enabled rapid, catchment
scale geomorphic analysis of river systems. In this paper, we present a semi-automated GIS …

High‐resolution raster hydrography maps are a fundamental data source for many
geoscience applications. Here we introduce MERIT Hydro, a new global flow direction map …

In response to the vital role of geomorphological analysis in natural hazards study,
geomorphology, distributed hydrology and other related disciplines, we present the first …

Spatial variability of river network drainage density (D d) is a key feature of river systems, yet
few existing global hydrography datasets have properly accounted for it. Here, we present a …

Since its introduction in 2008, the HydroSHEDS database (www. hydrosheds. org) has
transformed large-scale hydro-ecological research and applications worldwide by offering …

The shape, size and extent of a valley bottom dictates the form and function of the
associated river or stream. Consequently, accurate, watershed-wide delineation of valley …

The width of a river reflects complex interactions between river water hydraulics and other
physical factors like bank erosional resistance, sediment supply, and human-made …
