The number of civilian, commercial and military applications are dependant on accurate knowledge bathymetry coastal regions. Conventionally, hydrographic surveying methods used for bathymetric surveys carried by ship-based acoustic systems, but needs high-cost resources. Space technology has provided a cost-effective alternate means charting near shore inaccessible waters. optical satellite data have capabilities to offer solution in near-shore region, which been researched past 50 years,...
Widespread forest fire events occurred in the foothills of North Western Himalaya during 24 April to 2 May 2016 (Event-1) and 20–30 2018 (Event-2). Their impacts were investigated on distribution pollutant gases ozone (O3), carbon monoxide (CO), oxides nitrogen (NOx) over Uttarakhand using simulations Weather Research Forecasting model coupled with chemistry (WRF-Chem) in-situ observations these Dehradun, capital Uttarakhand. During Event-1, observed CO mixing ratio Dehradun increased from...
Stubble burning (SB) has been a major source of seasonal aerosol loading and pollution over northern India. The aftereffects groundwater preservation act i.e., post 2010 era (2011-2020) seen delay in crop harvesting thereby shifting the peak SB to May (Wheat SB) November (Paddy by 8-10 10-12 days compared pre-2010. Groundwater storage depletion rate 29.2 mm yr-1 was observed region. Post shows an increase 1.4% wheat 21% Paddy fires Punjab Haryana with 70% PM2.5 air mass clusters (high...
The combination of data from the Advanced Microwave Sounding Unit-A (AMSU-A) and Humidity Sounder (MHS) satellites provide measurements in frequency channels 23-183 GHz, which allow estimation vertical profiles atmospheric temperature humidity. These play a significant role numerical weather prediction models, improving initial conditions during tropical cyclone development. In present study, AMSU-A MHS have been assimilated Weather Research Forecasting (WRF) model through 3D-variational...
Morphological changes on Sagar Island are occurring at an alarming rate due to both natural and anthropogenic activities. The eastern part of the island is rapidly eroding destabilization growth tidal flats in Muriganga estuary gradual shifting water current towards island. Over last four years (1996–1999), coastal erosion has been much higher (11.35 km2) than accretion (2.65 km2), compared with conditions prior 1996. Coastal places like Dublat, Basantpur, Gobindapur, Collectorganj,...
This study presents an attempt to utilize seagrass data acquired from field surveys compare classification models for mapping seagrasses using Sentinel-2A satellite data.Out of three tested, viz.Random Forest, Support Vector Machine and K-Nearest Neighbor; Random Forest model proved most effective in the given scenario with 0.99 accuracy.Seagrasses present as deep 21 m were detected post water column correction, presenting capability detecting submerged benthic habitat.
The coastal zone of Sagar Island, India, is subjected to various cyclic and random processes that continuously modify the region. shoreline land-use/land cover changes have been studied using Indian Remote Sensing Satellite 1C (IRS IC) linear imaging self-scan sensor (LISS) III satellite data from 1998 1999. A comparison between a topomap 1967 1999 established during these years about 29.8 km coastline was eroded, whereas accretion only 6.03 km2. showed island had undergone severe erosion...
Abstract Various developmental projects have come up in the coastal zone of Dakshina Kannada and Udupi districts last few decades. A number beaches are subjected to erosion lots properties destroyed specially during SW monsoon season along Mangalore coast recent years. In order protect properties, a seawalls - each ranging length between 100 m 2500 built since 1980s. very them scientifically, but most just dumping granite blocks directly on shoreline. present study, an attempt is made...
