Wadden Sea, Annual Hydroperiod, 2016-2021

Abstract: Annual Hydroperiod maps utilizing inundation maps generated from Sentinel-2 data.

Methods: The annual hydroperiod is generated from a series of inundation maps (derived from EO data) by interpolating the inundation status per pixel as follows: if a pixel is inundated at two sequential (selected) dates, then it is assumed inundated for n-days, but n/2 days otherwise. The total number of days of inundation is determined by accumulating the pairwise derived results for all assessed date-pairs within a year.

TechnicalInfo: Annual Hydroperiod maps for 6 time periods (2015-2016, 2016-2017, 2017-2018, 2018-2019, 2019-2020, 2020-2021).
