The Geoscience Transect from Xiangshui,Jiangsu Province to Mandal,Inner Mongolia

The Xiangshui to Mandal geoscience transect, which has a total length of 1,200 km, extends diagonally,from SE to NW, across the Sino-Korean plate and its ancient continental margin, passing through nine tectonicunits: the Subei-Jiaonan terrane, West Shandong block, North China rift basin, Taihang-Wutai block, Ordosblock, Hu-Bao (Hohhot-Baotou) Basin, Yinshan block and Inner Mongolian fold system. The graphic display of the transect is compiled according to the Guidelines for the Global GeoscienceTransect (GGT) Project on the basis of an integrated study of all available geological, geochemical andgeophysical data, thus bringing light to the process of cratonization of the Sino-Korean plate and its relation-ship with the transitional zone of the ancient continental margin, and the features of intraplate structures pro-duced by subsequent tectonic modifications and intraplate dynamics.

Spatial-Temporal Analysis of LU/LC Classification in Nirmal Mandal, Adilabad, Telangana State, India, by Using Remote Sensing and GIS

In this project, we studied land use and land cover classification of Nirmal Mandal, Adilabad district, Telenagna state by using Geographical Information system and Remote sensing techniques. LISS-IV satellite image resolution 5 m × 5 m provides quality information for identification of Land use/Land cover characteristics. The image accuracy shows 45.70% of Agricultural land, 9.10% Built-up land, Forest area is 7.90%, Barren land have 7.60% and Uncultivated land occupied 29.70%. National land use and land cover mapping report based on 5 divisions classified in the study area. The area land use and land cover classification provide reliable data to understand land, water, soil, forests, urban sprawl. This socio economic survey significantly shows the changes that so far have taken place. This will help the people/farmers for the future land use and land cover change detection. Regular monitoring of agriculture, forest and greening efforts for plantation at suitable area, schemes and limitations. Free ware browsing of land cover gives sufficient development to plenty resource.

Hydrogeomorphology, NDWI and, NDVI of the Meghadrigedda Sub-Watersheds for Optimal Utilization of Resources, Visakhapatnam District, Andhra Pradesh-India Using Landsat Data 2000 and sentinel Data 2020

With global warming and over-exploitation of water resources due to population explosion and related issues, numerous studies are being carried around the world in an effort to reinstate a state of a balanced life between the existing water resources and their utilization by human beings. Keeping in view, a watershed of 366 sq.km on 1:50,000 scale 65O/1 SOI map surrounding the Meghadrigedda reservoir in Visakhapatnam district of Andhra Pradesh, India has been taken up for the study. The watershed has been delineated into nine sub-watersheds and hydrogeomorphology, drainage, drainage density, slope, NDVI and NDWI of the study area has been carried out using Landsat data 2010 and Sentinel data 2020 in ARCGIS 10.0 environment. All the villages in the catchment greatly depend on groundwater for irrigation, drinking as well as personal utilization. Change detection has been carried on to display the decline in surface water and ground water due to increased concentration of built-up land, siltation of ponds as well as decrease in the number of ponds. The watershed is experiencing large scale anthropogenic activities. The government must curb built-up activities and desilt the ponds to sustain the monsoon water, facilitating more recharge. The results of the study can serve as a basis for planning as well as for the development of a sustainable basin area.
