Title: Integrated approach of hydrogeomorphology and GIS mapping to the evaluation of ground water resources : an example from the hydromineral system of Caldas da Cavaca, NW Portugal
Publisher: Jodhpur : Scientific Publishers (India)
Issue Date: 2008
Abstract: Understanding the role of geomorphology is essential to accurately assess hydrogeological systems and groundwater resources. Hard-rock watersheds provide a source of valuable water resources. They commonly exhibit complex geological bedrock and morphological features as well as distinctive gradients in rainfall and temperature. A comprehensive evaluation and integrated groundwater resources study has been carried out for Caldas da Cavaca hydromineral system in NW Portugal, using hydrogeomorphology and GIS mapping techniques. Thematic maps were prepared from satellite imagery, topographical and geological mapping and other hydrogeological field data. These maps were converted to GIS format and then integrated using GIS software with the purpose of elaborating a hydrogeomorphological map intended to delineate the infiltration potential areas for the study region. Finally, this study highlights the importance of hydrogeomorphological cartography and groundwater GIS mapping as useful tools to support hydrogeological surveys, as well as for decision-making in the scope of management plans respecting to land and water resources and groundwater sustainability.
