The chemical composition of San Miguel river reflects that its drainage basin is located both on siliceous (shale and sandstones) and calcareous lithologies; likewise, the influence of tides is a/so present. By means of geochemistry modelling it has been proven that water chemical composition in the area of Tito Bustillo cave reflect a double influence: (1) 60% of discharge of groundwater by mean of springs and (2) 40% of water coming from the headstream.esinfo:eu-repo/semantics/openAccessEstudio hidrogeoquímico del sistema kárstico de la Cueva de Tito Bustillo (Ribadesella, Asturias)journal articlekarsthydrochemistrycultural and natural heritagewater quality
