Geospatial approaches of TGSI and morphometric analysis in the Mahi River basin using Landsat 8 OLI/TIRS and SRTM-DEM.

The research objective is to assess the Mahi River basin, morphometric parameters, and structurally controlled morphological terrains about the topsoil grain size index (TGSI), based on satellite data including Landsat 8 OLI/TIRS and SRTM-DEM data, using ArcGIS processing software. According to morphometric analysis, the Mahi River basin has an area of 28,844.2 km and is a drainage basin of the 8 order.

Geo environmental green growth towards sustainable development in semi-arid regions using physicochemical and geospatial approaches.

The process of determining whether a specific portion of land is suitable for a specific purpose is known as land suitability analysis (LSA). In order to promote sustainable development in semi-arid regions, the objective of this study is to analyse, evaluate, and identify the land for green growth based on topography, climate, and soil characteristics. Twelve thematic maps are prepared by using remote sensing satellite data.

Understanding the factors contributing to groundwater salinity in the coastal region of Andhra Pradesh, India.

The present study focused on understanding the factors responsible for groundwater salinity in the coastal region, Prakasam district, Andhra Pradesh, India. Groundwater samples were collected and analysed for pH, EC, TDS, TA, TH, CH, NCH, EA, Ca, Mg, Na, K, HCO, Cl, SO, NO, and F. Groundwater quality was assessed using entropy weighted water quality index (EWQI), Chadha and Gibbs diagrams, ionic ratios, chloro-alkaline indices (CA), saturation indices (SI), principal component analysis (PCA), and hierarchical cluster analysis (HCA).

Judging the sources of inferior groundwater quality and health risk problems through intake of groundwater nitrate and fluoride from a rural part of Telangana, India.

Evaluation of groundwater quality and related health hazards is a prerequisite for taking preventive measures. The rural region of Telangana, India, has been selected for the present study to assess the sources and origins of inferior groundwater quality and to understand the human health risk zones for adults and children due to the consumption of nitrate ([Formula: see text])- and fluoride (F)-contaminated groundwater for drinking purposes. Groundwater samples collected from the study region were determined for various chemical parameters.
