| Abstract | Erosion in active mountain belts is one of the key questions in geomorphology. Remote sensing can be a powerful tool to predict erosion on a quantitative scale and helps to understand the near-surface processes involved. One of the major limits in these kinds of environments is the lack of ground truth information and its inaccessibility. Here we present an integrated approach in order to validate remote sensing applications with on-site information in small catchments. Image classification (MLC) on SPOT-5 data is applied to map land-use and relate it spatially with typical erosion rates. Precipitation measurements from the Tropical Rain Measuring Mission (TRMM) are compared with real precipitations from a rain gauge network. Denudation rates derived from land-use classifications (soil erosion) are related to absolute denudation rates calculated from suspended sediment concentrations. Our results outline the intricacy of competing processes in active mountain environments and that it is possible to measure spatial erosion from remote sensing information. Nevertheless, the spatial resolution, especially of TRMM data is limiting the small-scale erosion prediction. |

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.
