Geological, geomorphological, hydrogeological and land use/land cover studies around kamthi area, Nagpur district, Maharashtra using remote sensing techniques

Remote Sensing Techniques in the evaluation of Polluted soils at illegal dumpsites in urban Soil environment and its effect on human being in Yenagoa metropolis, Bayelsa State compels us to investigate the presences of the following heavy metals, such as Fe, Mn, Cr, Cu, Zn, Ni, Cd, and Pb. The result reveals High-level of heavy metals accumulation at illegal dumpsites. Soil sample by leachate migration from the open dumpsite and all the illegal dumpsites found within the marketplace close to Epie Creek which serves as a significant source of household water and a tributary to River Nun. Our results also show that population increase in migration of human being from villages to the city in land use/land cover map built-up area contains 16.96 km2 with 4%, and bare land 20% in 1992 and 2020 land use/land cover built-up area contain 93.30 km2 with 23% and bare land is 35%. Therefore, the percentage from 1992 to 2020 in built-up area especially by 19% and bare land by 15% thereby water bodies and vegetation decreases. The area lacks environmental law for dumping disposals and the government needs to carry out landfill site suitability for solid waste disposal site using Remote sensing and GIS in other to reduce soil pollution by heavy metals in the area over time.

Abstract. The objective of this research study was to quantify land use and land cover changes before and after the 2010 flood at District Charsadda, Pakistan. The land use and land cover changes were evaluated with the help of advanced geographic information systems (GIS) and remote sensing techniques (RST). Moreover, some remedial measures were taken to develop land use/land cover of the area to overcome future problems. Land use and land cover changes were measured by using satellite images. Two instances were compared, i.e. pre-flood and post-flood, to analyze the change in land use/land cover of District Charsadda within 5 Km along the Kabul River. Comparative analysis of pre and post-flood imageries shows drastic changes over the water body, built-up area, agriculture land, and bare land during flood instances. The study area is rural and agricultural land is dominant in the area. We evaluated the percentage of different land uses/land covers within our study area, as agricultural land was about 68.5 %, barren land was about 22.5 %, and the water body was 8.8 % before the flood. After inundation, the water body raised to 16.4 %, bare soil increased to 26.30 %, agriculture land degraded up to 57 %, and settlements (villages) along River Kabul were badly damaged and finished by this flood. Approximately, four villages of District Nowshera, six villages of District Peshawar, and twenty-seven villages of Charsadda District were badly damaged during the 2010 flood.
