Authors:S. Srinivasa Gowd, P. Ravikumar, C. Krupavathi, G. Harish Vijay Pages: 1 - 14 Abstract: The purpose of this study was to assess the potability of groundwater resources in some parts of the Anantapur district of the Indian state of Andhra Pradesh. The water quality index, a spatial evaluation of groundwater using a GIS-based interpolation method, and the polluting groundwater index are some of the methods used to analyze water quality and explain the water quality of the studied area. A total of 22 groundwater samples were obtained during the post-monsoon period. The samples were tested for pH, EC, TDS, TH, and the major cations and anions. PIG levels between 0.98 and 1.98, with an average of 1.36, categorize low contamination in 5% of the research area and groundwater that is fit for human consumption. Additionally, 77% of the groundwater samples have drinking qualities that are only slightly acceptable. WQI values ranged from 85.97 to 113.52 mg/L, indicating that 55% and 45% of the samples are safe for drinking, respectively, while the other 45% are not. Groundwater samples are found in the field of rock dominance, according to the Gibbs plot. GIS techniques are being used to analyze the spatial variation of groundwater quality, and the results show that the majority of groundwater samples marginally meet standards for potable water, necessitating prior treatment before use.

Authors:Sheron Henry Christy Pages: 15 - 20 Abstract: Around the world, disasters are becoming a growing concern. Natural disasters like floods, earthquakes, severe storms and tropical cyclones, droughts, wild land fires, and man-made disasters like hurricanes and tornadoes have damaged the environment as well as destroyed economic and social infrastructure over the previous five decades. The Geographical Information System and Remote Sensing have been used as potential tools for disaster management and monitoring, particularly in the pre, during, and post-disaster stages. Utilizing electromagnetic radiation (EMR) wavelengths and sensors, multi-temporal spatial information can be obtained to simulate the disaster's nature in GIS which can aid to identify and predict the probability of upcoming disasters. For microclimate analysis and damage detection during large-scale natural disasters, the satellite covers a larger area than any other platform. Remote sensing technology for disaster management tasks has been broadened by compact aerial drones. UAVs can be utilitarian for mapping features of disaster impacted related in urban areas in real time. PubDate: 2022-12-21 Issue No:Vol. 13, No. 3 (2022)
