The study aims at delineating groundwater potential zones using geospatial technology and analytical hierarchy process (AHP) techniques in mining impacted hard rock terrain of Ramgarh part Hazaribagh districts, Jharkhand, India. Relevant thematic layers were prepared assigned weight based on Saaty's 9-point scale normalized by eigenvector technique AHP to identify prospect the area. weighted linear combination method was applied prepare index geographic information system. Final prospects...
Groundwater vulnerability and risk assessment is an essential step for preventing controlling contamination in any area. DRASTIC model with modification incorporating land use (LU) widely used assessing groundwater worldwide. The present study this modified termed as DRASTIC-LU considering LU a significant parameter addition to other conventional parameters. Geographic information system employed prepare integrate different maps led demarcate the zones catchment of Damodar River, Jharkhand,...
Accurately discerning lead–zinc open pit mining areas using traditional remote sensing methods is challenging due to spectral signature class mixing. However, machine learning (ML) algorithms have been implemented classify satellite images, achieving better accuracy in discriminating complex landcover features. This study aims characterise various ML models for detecting and classifying amidst surrounding features based on Sentinel 2 image analysis. Various associated band ratios indices...
Terrain variables are the main factors affecting spatial distribution of snow cover. This paper aims to find a relationship between snow-cover area (SCA) and topographic (elevation, slope aspect), using MODIS Terra data (MOD09A1) in parts Chenab basin, western Himalayas. The inter-annual variability SCA% for each month has been analysed years 2000 2011. analysis reveals that mean annual SCA value was maximum (37.89%) 2005 minimum (32.07%) 2001. classes with 5°–10° 30°–35°, respectively....
Solid waste management (SWM) is one of the poorly rendered services in developing countries – limited resources, increasing population, rapid urbanization and application outdated systems leads to inefficiency. Lack proper planning inadequate data regarding solid generation collection compound SWM problem. Decision makers need formulate solutions that consider multiple goals strategies. Given large number available options for inter-relationships among these options, identifying strategies...
Abstract This study highlights the assessment of snow and glacier cover for possible inferences global climate change impacts in high mountains like Himalaya. The test catchment River Tista lies Sikkim state Indian Himalayan region, with steep crossing nearly all ecozones, from subtropical to glacial. flows are highly fluctuating, especially during peak rainy season snowmelt periods. Annual rainfall patterns non‐uniform can cause large floods. Runoff discharge downstream dependent upon...
Kolkata is one of the four major metropolitan cities in India and capital city state West Bengal. With an area 187.33 km2 a population about 10 million (including floating 6 million), generates 3500 Metric Ton (MT) solid waste per day. Currently, Municipal Corporation (KMC) disposes its at Dhapa (21.47 ha), where disposal rate exceeds 3000 MT/day, Garden Reach (3.52 100 MT/day. Considering exhaustion land space, planners are urgently searching for alternate ground. National Environmental...
This article presents estimation and validation of tree heights extracted from synthetic aperture radar interferometry (InSAR) digital elevation model (DEM). InSAR technique was used to generate DEM in terms top the canopy surface (TCDSM). Multitemporal Radarsat-1 data pair February 12, 2004 March 7, Sentinel-1 December 9, 2017 21, were used. The TCDSM values at ground truth locations subtracted obtained forest gap areas (i.e., floor elevation). satellite-derived TCDSM-based height compared...
Sikkim state is rich in biodiversity with a vibrant traditionally strong conservation ethics place. This work aimed to understand the diverse systems of community forest management and their status special reference nature institutions governing them. As such, prolific luxuriant forests perceptible through remote sensing data based on derivations normalised difference vegetation index land use/cover. Existing practices such as sacred landscapes/groves, gumpa (monastery) forests, private...
