The SWOT Level 2 River Single-Pass Vector Reach Data Product from the Surface Water Ocean Topography (SWOT) mission provides water surface elevation, slope, width, and discharge derived from the high rate (HR) data stream from the Ka-band Radar Interferometer (KaRIn). SWOT launched on December 16, 2022 from Vandenberg Air Force Base in California into a 1-day repeat orbit for the "calibration" or "fast-sampling" phase of the mission, which completed in early July 2023. After the calibration phase, SWOT entered a 21-day repeat orbit in August 2023 to start the "science" phase of the mission, which is expected to continue through 2025.

Water surface elevation, slope, width, and discharge are provided for river reaches (approximately 10 km long) and nodes (approximately 200 m spacing) identified in the prior river database, and distributed as feature datasets covering the full swath for each continent-pass. These data are generally produced for inland and coastal hydrology surfaces, as controlled by the reloadable KaRIn HR mask. The dataset is distributed in ESRI Shapefile format. Please note that this collection contains SWOT Version C science data products.

This collection is a sub-collection of its parent: https://podaac.jpl.nasa.gov/dataset/SWOT_L2_HR_RiverSP_2.0 It contains only river reaches.

Springs in Somalia extracted from OpenStreetMap (October 2024) and normalized following UNESCO's template for groundwater data collection.

Wells in Somalia extracted from OpenStreetMap (October 2024) and normalized following UNESCO's template for groundwater data collection.

Wells in Kenya extracted from OpenStreetMap (October 2024) and normalized following UNESCO's template for groundwater data collection.

This dataset is part of the Somalia Water sources Information Management System (SWIMS). From the various sources listed in SWIMS boreholes and wells were selected. The dataset gives information about the positioning and in few cases about water level and yield but it is not clarified if the inspection date in the data is referring to the measurements.

Wells in Ethiopia extracted from OpenStreetMap (October 2024) and normalized following UNESCO's template for groundwater data collection.

Springs in Ethiopia extracted from OpenStreetMap (October 2024) and normalized following UNESCO's template for groundwater data collection.

Springs in Kenya extracted from OpenStreetMap (October 2024) and normalized following UNESCO's template for groundwater data collection.

Borehole dataset from UNICEF in part of Turkana County in northern Kenya. Water quality information with dates.

Overview of existing and known boreholes in each County (Turkana, Marsabit, Isiolo, Garissa, Wajir), including information of qualitative and quantitative potential (yield and EC). Note that this is a merged database containing data from the RAPID and UNICEF Hydrogeological mapping of underground water using remote sensing and GIS projects Provider: Acacia Water, RAPID + UNICEF project
