摘要：Supplying the population of a refugee or internally displaced persons (IDP) camp withsufficient drinking water is a key concern of humanitarian organisations. This requires informationon the geological and hydrogeological situation at the camp site, which is oftenmissing or not available within a reasonable timeframe. Depending on outcrop situation andgeological complexity, remote sensing can contribute to a rapid hydrogeological assessment,and greatly reduce the required fieldwork.In the context of the project EO4HumEn (Earth Observation based services to support humanitarianoperations: monitoring population and natural resources in refugee/IDPcamps, funded by the Austrian Research Promotion Agency FFG, ASAP 9, Nr. 840081), ateam of hydrogeologists and GIS experts supported by Médecins Sans Frontières (MSF)Austria developed a workflow to extract hydrogeological information from easily accessibleremote sensing data in a series of short-term desk studies.This paper provides a condensed, structured protocol on how to produce hydrogeologicalreconnaissance maps for humanitarian purposes using remote sensing data and GIS. Insimple geological settings, these maps can be sufficient to plan and conduct drillings. Inmore complex situations, fieldwork remains indispensable, but can be guided towards themost suitable locations.
