Description:

Abstract:

This dataset shows the flow accumulation on Pohnpei. 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, University of Guam (2017). 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 1975. 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.

Purpose: To show the flow accumulation on Pohnpei.

Supplemental_Information:

The dataset is included the Digital Atlas of Micronesia, module Pohnpei, by Island Research & Education Initiative (iREi), in collaboration with Water and Environmental Research Institute of the Western Pacific (WERI) University of Guam and partial funding from United States Geological Survey (USGS), under WRRI 104-B Program, project # 2016GU302B.
