  • This book explores the diversity of topics related to radiometric dating, with particular emphasis on the method of radiocarbon dating and a cross-check of its results with luminescence measurements. Chemistry and the global carbon cycle is an essential element of life on Earth, because carbon is a component of every living cell, plants and animals. The radioactive isotope 14C was found useful for dating, for which in 1960 Willard Frank Libby received the Nobel Prize in Chemistry.

  • Morphometric analysis, which refers to the science of quantitative analysis of land surface, has been carried on Kamleshwar watershed of Hiran River in Gujarat using remote sensing and GIS techniques. Digital Elevation Model of 30 m × 30 m resolution was used to prepare the detailed drainage map in ArcGIS software and stream ordering was in which study area has trunk order of 5. Total seventeen morphometric parameters including linear, areal and relief aspects have been estimated. Mean bifurcation ratio of the watershed has been calculated to be 3.

  • A detailed soil survey was undertaken in central state farm Jetsar, Sri Ganganagar, Rajasthan, India representing the arid climate with the aim of to assess the status and potential of land resources for the suitability and production potential of soils for chickpea. The area of the farm has been divided into three major landforms viz., sand dunes, reclaimed sand dunes and aeofluvial flood plain. Based on the variation in physiography and landforms, eight soil pedons were identified in the farm.

  • In this research, the applicability of geographic information system (GIS) and remote sensing (RS) techniques was tested to assess soil erosion risk with the ICONA erosion model. This study was carried out in the Ankara-Beypazari area because of its variety of diverse landforms, land uses and land covers.

  • Soils of Bino-river watershed in Almora district of Uttarakhand, India in north western Himalayas were characterised and classified for land categorisation and perspective land use planning. On the basis of interpretation of remote sensing data and ground truth verification three broad landforms viz., ridge tops, side slopes and valleys were identified and further sub-divided into seven landform units based on slope gradients. Nine types of soils (Pedons 1 to 9) were identified in the watershed area.

  • The Aravalli region in India is very prone to soil erosion and low hydrological regimes. The present study has been carried out in the Aravalli hill slopes to characterized land resources, identified soil problems to establish appropriate soil conservation measures in risk prone areas and appropriate land management practices. The integrated remote sensing (IRS-P6-LISS-IV and cartosat-1 merged data) and GIS based methodologies were employed for terrain analysis, identification of slope, landform, land use/land cover classes, hydro-geomorphology.
