Summary

To show the theoretical drainage pattern on Chuuk.

Description

This dataset shows the theoretical drainage pattern on Chuuk. The flow paths were delineated by Maria Kottermair, Island Research & Education Initiative (iREi)(2020). This was done through hydrological modeling using a 10-meter Digital Elevation Model (DEM) created by U.S. Geological Survey (1996-97)based on topography compiled in 1968. Note that in very flat low-lying areas the data may indicate straight lines that are an artifact of the modeling process and do not reflect reality.

When the process occurred 2019-06-10 00:00:00
Description
1. Ran hydrologic model using ArcHydro (fill, flow direction, flow accumulation, etc);
2. Clipped output features with updated shoreline;
3. Deleted artifacts along shoreline.
4. Added additional attributes.

Rationale
To create drainage lines and basins.
