Geometría y distribución espacial de la transmisividad en el Acuífero Mioceno del Sistema Mancha Oriental (Cuenca del Júcar)

Abstract

The hydrogeologic unit UH2 (Miocene Aquifer) supports a great amount groundwater abstractions and it is hydraulically connected to the Jucar river. Water withdrawal for irrigation purposes has driven to a regional groundwater level lowering which affects not only the river-aquifer system but probably the evolution and the status of the river ecosystems as well. Transmissivity is one of the main factors that control the interactions between groundwater and surface water bodies. In this work, the spatial distribution of transmissivity is analysed by means the use of geostatistical and GIS tools. This hydraulic parameter is studied in combination with the spatial variation of the saturated aquifer thickness. A non-linear relationship is found between transmissivity and saturated thickness as conconsequence of differences in the development of karstification in the UH2
