| Abstract | The tile drainage runoff composition during rainfall–runoff (R–R) events was examined in a small agricultural catchment Dehtáře (Bohemian-Moravian Highlands, Czech Republic). Drainage systems in this region of crystalline bedrock are typically built in slopes and they have complicated runoff generation. For runoff separation, analysis of stable isotopes $^{18}$O and $^{2}$H was used and compared to sudden changes in drainage water temperature. The analysis of 18 hydrographs showed that the drainage runoff was composed of 1–58 % event water during summer events, with a maximum temporary share of 11 and 88 %. During winter events, the pre-event water significantly dominated. In all cases when event water was detected in the drainage runoff, a rapid change in the drainage water temperature was observed as well. Its values during R–R events converged toward the temperature of the precipitation, which was very similar to that of the air (R $^{2}$ = 0.98 %). As the magnitude of the water temperature change was proportional to the event water portion in the drainage runoff (R $^{2}$ = 0.91), it is possible to state that a sudden change in drainage water temperature indicates the presence of event water in the drainage runoff and it is possible to use water temperature successfully to separate the runoff components. |

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.
