New Global Hydrography Derived From Spaceborne Elevation Data

Abstract: To study the Earth system and to better understand the implications of global environmental change, there is a growing need for large‐scale hydrographic data sets that serve as prerequisites in a variety of analyses and applications, ranging from regional watershed and freshwater conservation planning to global hydrological, climate, biogeochemical, and land surface modeling. Yet while countless hydrographic maps exist for well‐known river basins and individual nations, there is a lack of seamless high‐quality… Show more

“…At the core of this application is a river network routing model called RAPID [David et al, 2011b] simulating discharge in all river reaches of the Mississippi River Basin as described in a near-global hydrographic data set called HydroSHEDS [Lehner et al, 2008]. Estimates of surface and subsurface runoff were derived from second phase of the North American Land Data Assimilation System (NLDAS2), [Xia et al, 2012a[Xia et al, , 2012b [David et al, 2011b] is a river network routing model based on a matrix version of the Muskingum method given in equation (1).…”

“…At each resolution, the extra grid cells of the matrix are masked out as non-land cells and therefore are excluded from the simulation. All the subbasins are delineated using ArcSWAT [Neitsch et al, 2005] from the 90 m Digital Elevation Model (DEM) that was hydrologically conditioned using the 15 arcsec river networks extracted from the Hydrological data and maps based on Shuttle Elevation Derivatives (HydroSHEDS) [Lehner et al, 2008]. To be able to compare objectively against the grid-based approach at equivalent spatial resolutions, the area threshold used for delineation was adjusted iteratively until the average basin size at each resolution is roughly equivalent to the corresponding grid-based average size (Table 1).…”

“…To calculate F max , compound topographic indices (CTIs) are first derived following the definition used in TOPMODEL [Beven, 1997;Quinn et al, 1995] in ArcGIS from a 90 m DEM obtained from the HydroSHEDS [Lehner et al, 2008]. We then derived F max following the algorithms described in Niu et al [2005] in the same manner for each spatial resolution of both CLM and SCLM, except that for SCLM the CTIs are clipped following the boundaries of the subbasins in ArcGIS.…”
