Nicaragua water data

Water features across the area: rivers, streams, canals, lakes, ponds, and water bodies tagged with `waterway`, `water`, or `natural=water`. Useful for flood-risk modelling, watershed analysis, and environmental basemap context. Coverage reflects where volunteer mappers have been active. Urban areas are usually well represented, remote areas may be sparse. Cross-check critical decisions with local field knowledge. - Source: OpenStreetMap, a free, collaborative world map - Tags: waterway, water, natural - Part of the country exports on HDX by HOT

**UNOSAT code TC20221014NIC** This map illustrates cumulative satellite-detected water using VIIRS in Nicaragua between 12 to 16 October 2022 compared with the period from 27 September to 01 October 2022. Within the cloud free analyzed areas of about 240,000 km², a total of about 3,200 km² of lands appear to be affected. Water extent appears to have increased of about 2,300 km² since the period between 27 September to 01 October 2022. Based on Worldpop population data and the maximal flood water extent ~120,000 people are potentially exposed or living close to flooded areas amongst the 6,570,000 people living in cloud free areas. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to the United Nations Satellite Centre (UNOSAT).

**UNOSAT code TC20221014NIC** This map illustrates cumulative satellite-detected water using VIIRS in Region Autonoma del Atlantico Norte, Nicaragua between 12 to 16 October 2022 compared with the period from 27 September to 01 October 2022. Within the cloud free analyzed areas of about 30,000 km², a total of about 1,900 km² of lands appear to be affected. Water extent appears to have increased of about 1,400 km² since the period between 27 September to 01 October 2022. Based on Worldpop population data and the maximal flood water extent ~8,500 people are potentially exposed or living close to flooded areas amongst the 29,000 people living in cloud free areas. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to the United Nations Satellite Centre (UNOSAT).

**UNOSAT code: TC20201103NIC** This map illustrates satellite-detected surface waters in Puerto Cabezas, Prinzapolka and Launa de Perlas Municipality, Nicaragua as observed from Sentinel-1 image acquired on 08 November 2020. Within the analyzed area of about 12,000 km2, a total of about 1,200 km2 of lands appear to be flooded. Based on Worldpop population data and the detected surface waters, about 7,500 people are potentially exposed or living close to flooded areas. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR - UNOSAT. Important note: Flood analysis from radar images may underestimate the presence of standing waters in built-up areasand densely vegetated areas due to backscattering properties of the radar signal.
