Vulnerability Of Water Source Selected ForEmergency Water Supply In The Czech Republic

This paper deals with the semi-quantitative vulnerability assessment of the elements of hydrogeological structure and technological equipment of the source of ground water, which has been selected for the emergency supply of the population with drinking water. The vulnerability assessment stems from the application of the register of hazards and a potential threat to individual water source elements within each type of hazard. The semiquantitative assessment used the former general register of vulnerability together with the index assessment of vulnerability of source elements depending on the range of impact, i.e. its disturbance, damage, or destruction due to the activation of the source of the hazard. The outcome of water source vulnerability assessment was the assignment of a vulnerability index to each potential type of hazard and each threatened element. The acquired vulnerability indexes will become a basis for a source damage/destruction risk assessment in the case of each vulnerability/hazard pair and the following identification of critical risks and a source classification for the needs of crisis planning.
