Yes, I plan to use this model with other hydrologic models, both regional and global scale. +
National Hydrography Dataset (NHD) flowline datasets were used to evaluated the model. +
DEM raster and Hexagon shapefile, stream segment threshold +
Terrain analysis.
One equation is the resolution of a hexagon can be estimated using its area instead of edge length. +
It is best performance for high resolution (<100m) simulation.
With the version 3.0, coarser resolution is supported through stream burning feature. +
Hexagon DEM, flow direction, flow accumulation, stream grid, stream segment, stream order, stream confluence, subbasin, watershed boundary, etc. +
QGIS may be needed to preprocessing some files. +
DEM resampling;
Depression filling;
Flow direction;
Flow accumulation; +

HexWatershed is a mesh independent flow direction model for hydrologic models. It can be run at both regional and global scales. The unique feature of HexWatershed is that it supports both structured and unstructured meshes. +
