# Kosrae Flow Accumlation (modeled)

TypeRaster Dataset

Tags There are no tags for this item.

### Summary

    To show the flow accumulation on Kosrae.

### Description

    This dataset shows the flow accumulation on Kosrae. 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)(2019). This was done through hydrological modeling using a 10-meter Digital Elevation Model (DEM) created by U.S. Geological Survey (2001) based on topography compiled in 1967. 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.
