Introduction to the Dinaric Karst

open access: yes, 2010
Dinaric karst is expansive, 800 km long and up to 150 km wide area of karst, which extends over majority of Dinaric mountains and therefore also over the southwestern part of Slovenia.

The hydrogeology of bromate contamination in the Hertfordshire Chalk: incorporating karst in predictive models [PDF]

open access: yes, 2010
Point source contamination of groundwater by bromate (BrO3^-) in the Hertfordshire Chalk Aquifer forced the closure in 2000, of a major public supply ground- water abstraction and presents a continuing threat to regional water resources.

Investigations of rapid groundwater flow and karst in the Chalk [PDF]

open access: yes, 2009
This study, with fieldwork undertaken in the Pang and Lambourn catchments in Southern England, investigates the occurrence and distribution of rapid groundwater flow in the Chalk and evaluates the degree of karstification.
