      Abstract: Currently, wind and solar power generation systems have many drawbacks. Wind and solar power generation Full use of new energy will break the barrier to growth. Location for wind/solar hybrid power plant the primary problem is how to choose scientifically. This article selects six wind/solar hybrid power plants and implements them as a case study and evaluates these six areas via VIKOR by weighting the indicators through the MCDM method. Conclusions Related research findings and better valid, this demonstrates the feasibility and effectiveness of the method. This macro-site selection plants may provide some theoretical basis. In this statistical methods in the literature and established by statistical analysis. Tamil Nadu, Rajasthan, Maharashtra, Gujarat, Andhra Pradesh, Karnataka taken this alternative in this method and evaluation parameters are Total investment, Wind direction, Wind speed and speed change, sunshine stabilization, wind power density, energy saving, Environmental factors. Gujarat is on 2nd rank, Rajasthan is on the 1st rank, Tamil Nadu is on the 3rd rank, Indian Karnataka is on the 4th rank, Maharashtra is on the 5th rank and finally Andhra Pradesh is on the 6th rank.

      Abstract: Landuse play a role in the determination of main’s social, economic, and cultural progress. In general, the idea of land use is connected to the local physical environment. Landuse reflect a complex correlation between natural historical and socio-economic factors. Besides, size of holding and caste structure determine the changing of land use on the agricultural crops. Such as undulating terrain and hilly poor land determine the process of farming and as-well-as sometime at the capacity of farmers. The present study characteristics of changing pattern of land use in the Sagar district. Slightly more-than half (52.64%) of the total geographical area is net sown in 2021. This proportion is higher than the 48.93% statewide average. An additional 2.29% of the total area is made up of fallow areas. As a consequence, around 75% of the land had farmed. The forest land (24.46%) is quite similar to the average distribution. Around 1.69% of the area is designated as barren and uncultivable due to physical limitations. For a number of reasons, other uncultivated land accounts for about 10.65% of the total area. Land use patterns are influenced by cropping practices and intensity of farming as well as human social and economic position, institutional makeup, and technology advancements. The terrain of its land is ridged on a big chunk of it. Therefore, regional balances of natural processes within them are crucial prerequisites for the rising population's access to food security and its ability to get the most out of the resources at hand.

      Abstract: The ruling aspect of the present investigation is to study the textural characters as well as to understand the grain size relationship and distributionby engaging granulometric analysis, along the Pennar estuary, South east coast of India. An aggregate of 36 Surface sediment samples were retrieved and a comprehensive study of textural parameters and various size distribution of sediments were analysed at six various stations in six different micro – environments viz., dune, backshore, berm, upper foreshore (UFS), middle foreshore (MFS) and lower foreshore (LFS).  These were further subjected to statistical treatment viz., Mean size (Mz), Skewness (Sk), Standard deviation (σI), and Kurtosis (KG). The procured results indicates that the sediment samples were coarse to fine grained, very negatively skewed to positively skewed, very well to moderately sorted, and platy tovery leptokurtic in nature and also indicates two mixed environments at some stations. Scatter plots were help to understand the mode of deposition, geological significance and transportation of grains along the coast. Scatter plots also divulges that the sediments along the coast were mainly associated with fluvial process. C-M diagrams demonstrate the type of transportation and deposition of the beach sediments. Ebbing and flooding shows prominent role in changing the characteristics of grains in the Pennar estuary, especially in the estuarine mouth and adjoining river areas.

  • Assessment of Groundwater Quality Using Water Quality Index (WQI),
           Pollution Index of Groundwater (PIG), and GIS in Parts of Anantapur

      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.

  • Role of Satellite Sensors & GIS in Discrete Phases of Disaster
           Management

      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.
