The present map shows the flood delineation during the most critical period of the rainyseason in February-March 2008 in the area of Mamoré River in El Beni Department(BOLIVIA). The basic topographic features are derived from public datasets, refined bymeans of visual interpretation of pre-event Landsat-8 imagery.The thematic layer, assessing the delineation of the event at its peak, has been derived frompost-event Landsat-5 images. Please note that flooded areas extracted from the scenesacquired on 10/02/2008 are more limited.All satellite images have been radiometrically enhanced and orthocorrected with RPCapproach (using SRTM elevation data).The estimated geometric accuracy of this product is 90 m CE90 or better, from nativepositional accuracy of the background satellite image.The estimated thematic accuracy of this product is 85% or better, as it is based on visualinterpretation of recognizable items on high resolution optical imagery. Shadowed areas arezones of lower interpretation accuracy due to the poorer image radiometry. Some floodedareas hidden by clouds may not have been extracted.Only the area enclosed by the Area of Interest has been analyzed.Map produced on 24/10/2014 by SIRS under contract 257219 with the EuropeanCommission. All products are © of the European Commission.Name of the release inspector (quality control): SIRS (ODO).E-mail: [email protected]
The products elaborated in the framework of current mapping in non-rush mode activation arerealized to the best of our ability, within a relative short time frame, optimising the availabledata and information. All geographic information has limitations due to scale, resolution, dateand interpretation of the original data sources. The products are compliant with GIO-EMSNON-RUSH Product Portfolio specifications.
The northern territories of Bolivia are regularly affected by massive flooding during the rainyseason, which runs from October to April. Departments El Beni and La Paz (northern part)are particularly exposed because of extensive wetlands and the presence of large rivers suchas Beni and Mamore. During the past decade, the floods which occurred in 2008 and 2014appear to be the most significant events.Local authorities express the need to better know the areas prone to floods and vulnerabilityof populations and infrastructure. Proposals related to protection measures and evacuationplans for the most populated locations (Trinidad, Santa Ana del Yacuma, Rurrenabaque andGuanay) will be part of the analysis.
Delivery formats are GeoTIFF, GeoPDF, GeoJPEG and vectors (shapefile and KML formats).
