| Abstract | A GIS-based irrigation water quality (IWQ) assessment of the Dwarka river basin was undertaken using water suitability indicators including determinations of values of: soluble sodium percentage, exchangeable sodium ratio or Kelly ratio, residual sodium carbonate, magnesium adsorption ratios, total hardness, sodium adsorption ratio and permeability indices, electrical conductivity, and fluoride concentrations (F$^{−}$). Inverse distance weighted algorithms and weighted overlays were used to categorise irrigation water quality into a number of zones. The IWQ zonation analysis revealed that about 10% (42.15 km$^{2}$) of the total area had water quality unsuitable for irrigation thereby potentially exposing a population of 35744 people from 110 villages to health risks, whereas the remaining 91.31% (393 km$^{2}$) of the study area is considered to have suitable irrigation water. The villages of Nawapara, Sehara and Deucha have been particularly affected by poor water quality, potentially exposing 294 (100%), 114 (97%) and 1556 (87.76%) of the total village population, respectively, to health effects. Combined efforts of government agencies and NGOs in educating the local communities regarding artificial groundwater recharge, rainwater harvesting, watershed management can play a crucial role in the long run in minimising the potential impacts of poor water quality in these areas. |

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.
