Description: 〈p〉〈em〉This work provides an overview of the use of remote sensing and Geographic Information System (GIS) techniques for mineral exploration. The integration and analysis of various data types, including geological, geochemical, geophysical, and remote sensing data, using remote sensing and GIS tools allow for the creation of comprehensive maps and models of mineral deposits. The advantages of remote sensing and GIS in mineral exploration include more effective targeting of exploration activities, assessment of environmental and social impacts of mining activities, and creation of predictive models of mineral deposits. However, limitations to their use include the quality and resolution of input data, the expertise of the user, and availability and accessibility of data. As technology continues to improve and the availability of data increases, the use of remote sensing and GIS is likely to become even more important for the efficient and sustainable exploration and development of mineral resources.〈/em〉〈/p〉

Description: 〈p〉〈em〉Urban sprawl is increasing rapidly with the increased rate of rural to urban migration and with the tremendous population growth. Due to rural-urban migration and continuous population growth; urban centers tend to expand outwards to lodge the ever-increasing population pressure. Urban sprawl has to be considered in spatio-temporal terms to understand the phenomena of urban growth, land use and land transformation.  Urban sprawl is momentous to the quality of life of urban dwellers as well as quantity of rural land lost and land degradation; key issues of agricultural as well as environmental perspectives. Himalayan state of Uttarakhand is witnessing steady and continuous urban growth. Urban sprawl in Ranikhet tehsil has resulted in loss of productive agricultural land of the surrounding rural areas, open green spaces, loss of surface water bodies, and depletion of groundwater too. Problems of dwellings, slums, and unhygienic livings are also growing rapidly with the rapid urban sprawl. There is regular competition between urban and rural areas for land needed for growth and development.  The present study finds out that the built-up areas of different towns of Ranikhet tehsil have been increased from 4.92km〈sup〉2〈/sup〉 in 2000 to 6.19km〈sup〉2〈/sup〉 in 2010 which has further been increased to 7.70km〈sup〉2〈/sup〉 in 2020 witnesses a continuous struggle for space in Ranikhet tehsil.〈/em〉〈/p〉

Description: 〈p〉〈em〉Flood hazard mapping, which uses model and satellite remote sensing data, is extremely useful for flood monitoring and risk management. The flood inundation extent and flooding depth on Majuli Island and its surrounding area in Assam, India, were simulated using MIKE FLOOD, a coupled 1D-2D hydrodynamic model. MIKE FLOOD is a platform that integrates the MIKE Hydro River (1D) and MIKE 21 FM (2D) models into a dynamically coupled single modeling framework. The study employed daily discharge and water level data from several gauging stations operated by the Centre Water Commission (CWC), Global Flood Monitoring System (GFMS), and Water Resource Department (WRD) of Assam. First, the MIKE Hydro River (1D) model was calibrated using discharge and water level data from 2016 to 2018 and validated for the period of 2019-2021. The MIKE Hydro River (1D) model's calibration and validation results were evaluated using a numerous of performance metrics. From ALOS PALSAR DEM data / SRTM DEM data, a fine mesh and bathymetry of Majuli Island with a spatial resolution of 10m has been created and provided as an input to the MIKE 21 FM (2D, Flow Model). The MIKE Hydro River (1D) and MIKE 21 FM (2D) models were then linked to the MIKE FLOOD model for simulating two-dimensional flood inundations in the study area through lateral linkages. Flood inundation has been simulated for the year 2020, and the model's maximum flood inundation extent has been compared to the actual flooded area retrieved from Sentinel-1 C-Band satellite data. The R〈sup〉2〈/sup〉 in the study area was ranging between 0.86 and 0.97, but the WBL in the MIKE Hydro River model was less than 1.23. On the opposite hand, the MIKE FLOOD's total accuracy is 93.6 percent according to the confusion matrix. According to the most recent model simulation, flooding will occur between July 19 and July 21, 2020, with the greatest and lowest flood depths being 2.38 and 0.786 m, respectively〈/em〉〈em〉. In addition, the MIKE FLOOD model may be used for flood control in the future, and this research will aid policymakers in the field of water management in achieving successful mitigation measures.〈/em〉〈/p〉

Description: 〈p〉〈em〉〈span〉This study delves into the management of electronic waste (e-waste) stemming from the disposal of personal electronic items and mobile phones, primarily in response to the remarkable surge in the utilization of these devices within the Hassan city populace in recent years. The principal objectives revolved around investigating the existing disposal methods for electronic devices including mobile phones and collecting fundamental data concerning their disposal practices within the geographical confines of Hassan city of Karnataka State. Additionally, an endeavor was undertaken to gauge the level of awareness among respondents regarding the potential hazards posed by e-waste. It was observed that a significant proportion of the Hassan population typically retains especially electronic devices is cell phones, once these devices become outdated and obsolete. Among the prevalent disposal methods, the most widespread approach involves selling these gadgets to scrap dealers or junk shops, whereas recycling practices remain relatively underutilized. Notably, a mere minority of individuals engage in recycling activities. An intriguing revelation emerged, with 65% of respondents expressing concern about the adverse repercussions of improper e-waste disposal on human health and the environment. Astonishingly, all respondents admitted to having no knowledge of the fate of their discarded electronic devices. Based on the findings gleaned from this survey, it is strongly recommended that a comprehensive review be conducted on the overarching management of e-waste stemming from this electronic waste including mobile phones, gadgets in the Hassan city of Karnataka State. The purpose of these surveys and data collection endeavors is to approximate the volume of e-waste generated through the disposal of these devices. This information is envisioned to assist stakeholders and government agencies in formulating effective and efficient legislation and policies for the proficient management of e-waste〈/span〉〈/em〉〈/p〉

Description: 〈p〉〈em〉Indian Railroads is one of the largest railroad systems in the World. The Indian railway system has grown significantly over the years, as seen by the massive construction of its railroads; nonetheless, some accidents are caused by fractures in the railway track. Splits may occur because of the track's expansion or contraction brought on by seasonal variations. This study proposes a crack monitoring vehicle that employs an ultrasonic sensor to detect fractures on railway tracks and uses an Arduino Uno to facilitate the GSM and GPS module to send an SMS to the testing station, thereby mitigating the problems caused by these cracks. This intelligent system works like a remote monitoring system which gives an alert to stop the passage of trains in that path. The proposed model involves the use of Arduino, ultrasonic sensor, buzzer, GSM module, and GPS module.〈/em〉〈/p〉
