An improved maze solving algorithm (MSA) is then introduced to assign the flow directions by constraining its searching directions, direction weights and searching range. The paths from the destinations to the origin are obtained iteratively based on the improved MSA according the path importance. ...
The improved method is applied to derive global river network maps at various resolutions. It succeeded to preserve the river network structure of the original flow direction map, and consequently realizes automatic construction of river network maps at any resolutions. This enables both higher-...
4a, b). These maps confirmed that flow noise color is highly variable across and within river networks. Daily flow noise decreased (from red to pink) from the northwest to the southeast, but increased again (from pink to black) when approaching the coastal belt (Fig. 4a). In contrast, ...
MERIT Hydro21is a global hydrography dataset developed based on the MERIT DEM. It provides high resolution (3 arcseconds) data of flow direction, elevations, drainage area, and river channel width. We downloaded the river channel width data fromhttp://hydro.iis.u-tokyo.ac.jp/~yamadai/MERI...
A tool to generate river meshes with flow and foam maps based on bezier curves. - Arnklit/Waterways
riverdistance(),riverdirection(), andupstream()return the network distance, the travel direction (upstream or downstream), and the directional (upstream) distance between two river locations, respectively. Options are included for different handling of locations that are flow-connected or flow-separate...
Using an automated partitioning method, we generate daily maps of (1) snow over glacier ice, (2) exposed glacier ice, and (3) snow over land. These are inputs to a temperature index model that yields melt water volumes contributing to river flow. Results for the five major High Mountain...
Through the design of short-, medium- and long-term policy implementation roadmaps, the project will eventually propose policy recommendations for incorporating NECA and EFM with high-quality development and high-standard protection for both YREB and Yellow River basin. 5.2 Status and Trends 5.2.1...
1c), which in turn would affect the large-scale flow. The presence of indirect links (or confounders) is confirmed by Fig. 1c, generated using PCMCI. Since PCMCI conditions on all necessary variables from the input set (“Methods”), it should show fewer links than Granger Causality (...
Atmospheric rivers distribute heterogeneously over the North Pacific. Here, we identify five cross-Pacific atmospheric river main routes (i.e., preferred migratory path) by Self-organizing map automatically. They originate from East Asia or the western N
