Abstract The accuracy of the predictions distributed hydrological models must depend in part on proper specification flow pathways. This paper examines some problems deriving pathways from raster digital terrain data context using TOPMODEL. Distributed moisture status is predicted TOPMODEL basis spatial indices that path definition. sensitivity this index to algorithm and grid size examined for case where surface topography a good indicator local hydraulic gradients. A strategy downslope...
Abstract Mass-balance and dynamic behaviour of Chhota Shigri glacier, western Himalaya, India, has been investigated between 2002 2010 compared to data collected in 1987-89. During the period 2002-10, glacier experienced a negative glacier-wide mass balance -0.67 ± 0.40 m w.e. -1 . Between 2003 2010, elevation ice-flow velocities slowly decreased ablation area, leading 24-37% reduction ice fluxes, an expected response dynamics its recent balances. The reduced fluxes are still far larger than...
Little is known about the Himalayan glaciers, although they are of particular interest in terms future water supply, regional climate change and sea-level rise. In 2002, a long-term monitoring programme was started on Chhota Shigri Glacier (32.2° N, 77.5° E; 15.7 km 2 , 6263–4050 ma.s.l., 9 long) located Lahaul Spiti Valley, Himachal Pradesh, India. This glacier lies monsoon–arid transition zone (western Himalaya) which alternately influenced by Asian monsoon summer mid-latitude westerlies...
Abstract. A major proportion of flow in the Indus River is contributed by its snow- and glacier-fed river catchments situated Himalaya, Karakoram Hindukush ranges. It therefore essential to understand cryosphere dynamics this area for water resource management. The MODIS MOD10A2 remote-sensing database snow cover products from March 2000 December 2009 was selected analyse changes Hunza basin (the sub-catchment River). daily flows at Dainyor Bridge over a period 40 yr climate data...
The $K$ x-ray spectrum arising from doubly $K$-ionized gallium atoms has been studied by means of a coincidence experiment with two solid-state detectors. A new energy range in spectra (hypersatellite range) is observed. Hypersatellite lines are shifted about 15 times more than the usual satellite lines. $K$-satellite following $\mathrm{KL}$-ionized states also studied.
Snow is a crucial component of the hydrological cycle in Western Himalaya. Water from snowmelt used various sectors downstream regions, thus playing critical role securing livelihoods millions people. In this study, we investigated future evolution snow cover and Panjshir catchment Afghanistan, sub-basin Indus, We applied three-step approach to select few global climate model (GCM) simulations CMIP5 datasets for RCP4.5 RCP8.5, which showed reasonable performance with ERA5-Land dataset chosen...
Presents the first observation of pure K hypersatellite lines copper, nickel and iron obtained under electron bombardment. The absolute energies these are compared with results from various calculations, decay scheme K-2 ionized states is studied in LS coupling dipole approximation. In case copper both alpha 2h 1h hypersatellites observed; relative intensities lines, which represent a test intermediate coupling, discussed.
The n=2\ensuremath{\rightarrow}n=1 lines of hydrogenlike and heliumlike uranium have been observed are being reported for the first time. spectrum consists all allowed forbidden lines. We done a preliminary energy measurement these with precision in (4--12)\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\ensuremath{-}}4}$ range.
Abstract To determine the physical processes involved in melting and disappearance of transient snow cover nonglacierized tropical areas, CROCUS model, interactions between Soil–Biosphere–Atmosphere (ISBA) land surface coupled ISBA/CROCUS model have been applied to a full set meteorological data recorded at 4795 m MSL on moraine area Bolivia (16°17′S, 68°32′W) 14 May 2002 15 July 2003. The models adapted conditions, particular high level incident solar radiation throughout year. As long as...
In the region of basaltic plateau in Southern Brazil, problems runoff and erosion on deep ferrallitic soils are becoming increasingly recognized. Land use change from conventional tillage using disk plough to no-tillage residues without terracing occurred at beginning 1990s it spread very quickly. Measurements sediment concentrations 1 m2 plots receiving natural rainfall simulated under different crops with stages growth systems, field surveys measurements rills gullies nested experimental...
The Vakhsh and Pyandj rivers, main tributaries of the Amu Darya River in mountainous region Pamir Alay, play an important role water resources Aral Sea basin (Central Asia). In this region, glaciers snow cover significantly influence cycle flow regime, which could be strongly modified by climate change. present study, part a project funded European Commission, analyses hydrological situation six benchmark basins covering areas between 1800 8400 km2, essentially located Tajikistan, with...
The glaciers in the Nepalese Himalayas are retreating due to rising temperatures. Lack of data and information on Nepal's cryosphere has impeded scientific studies field investigations Himalayas. Therefore, IRD France Ev-K2 CNR Italy have conducted PAPRIKA (CryosPheric responses Anthropogenic PRessures HIndu Kush-Himalaya regions: impacts water resources society adaptation Nepal) project Nepal with financial support French Italian agencies. This aims address current future evolution response...
