| Abstract | Most part of the vast scientific literature dealing with channel adjustments focuses on the period between the second half of the twentieth century and nowadays, when most of the adjustments occurred and data availability is generally great. On the contrary, few studies were carried out on older adjustments, notwithstanding their analysis is fundamental to fully understand both more recent evolutionary trends and the role possibly played by human disturbances. The lack of studies on older adjustments is total for rivers located in southern Italy. The present study attempts to partly fill this gap. An analysis of the planform changes experienced by Tammaro R. between 1870 and 1955 was carried out by means of a detailed GIS-aided analysis of historical maps. The results were interpreted in the framework of the pre-existing geomorphological, geographical and socio-economic literature. This latter highlighted that the Tammaro R. basin in the studied period was scarcely inhabited and almost un-anthropized, especially in the first part of the studied period. Between 1870 and 1909, the river underwent a slight and quite inhomogeneous widening and moderate increase in fluvial bars, together with a slight straightening and shortening, but without substantial changes in channel morphology, which was single-thread. Between 1909 and 1955, the river experienced a homogeneous and marked widening, increase in sinuosity and lengthening, together with a strong increase in fluvial bars, and the channel morphology drastically changed from single-thread to transitional. This trend was opposite to that of most rivers in that period, possibly because of the scarce human impact on both the Tammaro R. and its basin. |

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.
