| Abstract | Based on an inventory of more than 200 facilities for the treatment of road runoff water in Sweden, 26 representative stormwater ponds were studied with regard to technical function, maintenance and metal accumulation. Sediment accumulation and metal content in the pond sediment was studied in relation to concentration in the runoff water, spatial variation and pond geometry.It emerged that the pollution retention capacity was not optimal for many of the ponds. The observed sediment thickness was low reflecting turbulent conditions and that much of the pollutants are transported through the ponds. Statistical tests performed on 15 ponds showed a significant relationship between metal content in sediment and pond size while pond shape was found to have no effect on accumulation rate. There is still significant potential for the development of the design and technical function of the ponds, e.g. design elements such as pre-settlement trench and elements for enhancing high hydraulic efficiency.Disturbance of the technical function, in terms of clogging of pipes, erosion, flooding etc. was reviewed for three of the ponds, however only 50% of the ponds did show some form of documented maintenance-program. This generates an obvious threat to the effective long-term function of these ponds. |

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.
