| Abstract | Soil piping (tunnel erosion) is a soil-related natural disaster. It is a type of sub-surface erosion, which involves the hydraulic removal of sub-surface soil causing the formation of an underground passage in landscape. Soil piping significantly affects the most responsive run-off systems of the humid tropics. Southern parts of the Western Ghats have recorded seven incidents of this phenomenon within a period of 1 year, starting from August 2010 to August 2011. Out of the seven incidents recorded from the Ghats regions falling in Idukki District of Kerala, south India, the main aspects and parameters of four locations were evaluated and correlated by synthesizing the physical, chemical, geological and hydrological parameters. The evaluation showed a similar expression of physical, chemical and hydrological components of soil at the sites 1, 2 and 4, which does not normally favour the phenomena of soil piping, while site 3 has chemical components favouring its development. Even though the pipe outlets were observed at or near the foothills, the mechanism behind the recharging is to be clarified further more. The study reveals that the phenomenon has been recorded from a variety of geographical entities with no common contributing system, except the intensity of rainfall and vicinity to prominent structural controls. Hence, the increased periodicity of occurrence of the incidents is attributed to the stress-induced dilatation of the sub-surface water-bearing formations before and after a series of mild tremors recorded contemporaneously from Idukki District, Kerala. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
