| Abstract | Aquifer group classification is a prerequisite for groundwater resources evaluation as well as groundwater utilization, which making an important effect on human being living and production activities. So far, lithology is the primary criteria in aquifer group classification, but the available and specific supporting ideas are still insufficient. Supposing that two aquifers separated by clay had hydraulic connection in multilayer aquifer systems, groundwater flow from top to bottom of aquifer would be impacted by the clay in chemistry and isotope characteristic and presents some kind of regulations. According to these regulations, aquifer group classification would be more reasonability, and groundwater resources assessment and pollution management would be more purposeful. This research analyzed the hydraulic connection of groundwater in different aquifer and salt movement in clay soil by using isotopic and chemical data. The results showed that electrical conductivity of groundwater in clay soil is influenced by the source of the groundwater, having a continuous trend with depth, and clay soil in certain depth presented the feature of impeding salt migration. Because of the semipermeable feature of clay soil, stable isotope composition of groundwater in different depth is affected by clay’s distribution. This pattern of isotope and hydrogeochemical composition would be a valuable reference for groundwater evaluation and aquifer group classification. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
