Systematic observations of Himalayan glaciers over the last few decades provide reliable indications continuous shrinkage most glaciers. Changes in mass, volume, area and length are reported, but an up-to-date regional assessment glacier changes is lacking. In present study, satellite data, maps ground-based measurements have been used to obtain snout retreat surface Tipra Glacier Alaknanda river basin Garhwal Himalaya for period 1962–2008. The study reveals that a large part has detached...
We analysed the recession of Milam glacier in Gori Ganga River valley, Uttarakhand Himalaya using historical plane-table survey maps, topographical Corona image (1968), Landsat 5 TM (1990), 7 ETM+ (2001) and Sentinel 2 (2017) satellite data. estimate that has receded by 1565.4 ± 20.6 m (31.9 0.4 a-1) over period 1968-2017, while lower rate (21.1 1.7 was observed between 2001 2017. The lost 2.27 0.06 km2 its area from 1968 to 2017 due recession. Two tributary glaciers detached main trunk 1990...
Abstract Quantitative morphometric analysis of Dhanari watershed has been done using remote sensing and Geographical Information System (GIS). The impact climate, lithology, tectonics, structural antecedents, vegetation cover land use on hydrological processes is assessed by quantifying geomorphic parameters. River (a tributary the Bhagirathi River) its tributaries Dhanpati Gad Kali forms covering 91.8 Km 2 area. Several aspects viz. linear, areal, relief were computed to comprehend...
ABSTRACT This research paper focuses on evaluating the suitability of drain water, whether untreated or treated, for irrigation purposes in a peri-urban region southwest Delhi, India. A total 11 water samples were collected during pre-monsoon (PRM) and post-monsoon (POM) seasons. comprehensive assessment various quality parameters, including pH, EC, major cations (Na+, Ca2+, Mg2+, K+), anions (Cl−, HCO3−, SO42−, NO3−, F−), heavy metals, (SAR, Na%, RSC, KR, MH, PI) analyzed. The results...
Medicinal plants are known for their traditional and modern medicinal values to treat health disorders. Dactylorhiza hatagirea (known as Hattajari Salampanja) is one of these plants, which highly praised valued plant in alpine regions. The has been widely used by the local inhabitants treating various ailments due its demand increased herbal industries. present study evaluates distribution threat status using extensive field surveys MaxEnt computer package. was assessed environmental...
Kumaun Himalaya is a home to various threatened medicinal and aromatic plants. Picrorhiza kurroa plant useful in curing many diseases Indian Himalayan region. Due overharvesting from the wild its population decreasing at an alarming rate. The present study attempted assess availability predict highly suitable areas for situ conservation alpine region of Kumaun. Availability P. across meadows was evaluated through rapid mapping exercise. MaxEnt model used geographical distribution species...
A threatened endemic Himalayan herb discovered from the Valley of Flowers National Park (VoFNP). Gentiana tetrasepala Biswas belonging to family Gentianaceae was rediscovered by Rawat (2009) after a long gap 123 years Garhwal Himalaya. In our investigation climatic and glacial variation within VoFNP, recorded for first time. The Flowers, world Heritage site situated in alpine meadows District Chamoli state Uttarakhand. Recording G. an VoFNP is good indication although, due recent habitat...
Several high-elevation plant species would experience an increased risk of regional extinction due to various climatic and anthropogenic factors. Information about the effects climate change is urgently needed for modeling vegetation dynamics because it influences seed parameters like germination, maturation, mass, bank in soil. The present study was conducted at elevation 3145–3560 m treeline area western Himalayan region India. color correlated with other such as moisture content, fall...
Abstract. Landslides are one of the frequently happening disasters in this hilly state Uttarakhand which accounts to loss lives and property every year especially during rainy season lead affect families. With development satellite observation technique, advanced data analysis tool new modeling techniques landslide hazard zonation map can be prepared.In present study, Landslide Hazard Zonation (LHZ) for Kedarnath Augustmuni region Rudraprayag district was carried out using Remote Sensing GIS...
Abstract. Management could be improved through the use of current technologies including Remote Sensing and Geographic Information System (GIS).The present study was carried out to identify potential agriculture sites in Yamuna basin Uttarkashi district Uttarakhand. The characterization natural resources undertaken using satellite imagery (Sentinel -2, LISS IV, III, Aster DEM (30 m) Survey India Toposheet generate several layers maps such as Watershed Boundaries,Drainage, Soils, Land cover,...
