Type Raster Dataset
To show the flow accumulation on Chuuk.
This dataset shows the flow accumulation on Chuuk. Flow accumulation describes the amount of water in streams. The higher the value, the more water a particular location receives from areas uphill. The dataset was 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.
