Understanding the potential impact of climate change on hydrological regime in Himalayan region is great importance for sustainable water resources management. This study assessed historic and projected trends Koshi river basin using statistical analysis. The characteristics contribution different runoff components under present future conditions were investigated Dudh sub-basin J2000 model. Data 1995 to 2096 from Providing REgional Climates Impacts Studies (PRECIS) regional model used...
Future hydrological extremes, such as floods and droughts, may pose serious threats for the livelihoods in upstream domains of Indus, Ganges, Brahmaputra. For this reason, impacts climate change on future extremes is investigated these river basins. We use a fully-distributed cryospheric-hydrological model to simulate current fluxes force with an ensemble 8 downscaled General Circulation Models (GCMs) that are selected from RCP4.5 RCP8.5 scenarios. The calibrated observed daily discharge...
Understanding the upstream-downstream linkages in hydrological processes is essential for water resources planning river basins. Although there are many studies of individual aspects these Himalayan region, along length basins limited. This study summarizes present state knowledge about between upstream and downstream areas region based on a literature review. The paper changes physical environment (land use, snow storage, soil erosion) climate change availability, flood dry season flow,...
This paper provides the results of hydrological modelling in a mesoscale glaciated alpine catchment Himalayan region. In context global climate change, regime an mountain is likely to be affected, which might produce serious implications for downstream water availability. The main objective this study was understand system dynamics catchment, Dudh Kosi River basin, Nepal, using J2000 model and thereby how rise air temperature will affect processes. able reproduce overall quite well with...
Global climate change has local implications. Focusing on datasets from the topographically-challenging Karnali river basin in Western Nepal, this research provides an overview of hydro-climatic parameters that have been observed during 1981–2012. The spatial and temporal variability temperature precipitation were analyzed considering seven available stations 20 distributed basin. non-parametric Mann–Kendall test Sen’s method used to study trends data. Results show average is heterogeneous,...
Sediment connectivity, defined as the degree of linkage between sediment sources to downstream areas, is one most important properties that control landscape evolution in river basins. The linkages amongst different parts a catchment depends mainly on hinterland characteristics (e.g. morphology, slope, shape, relief, and elevation), channel stream network density, valley confinement), combined effects vegetation land use changes abandonment). This paper evaluates connectivity upper Kosi...
Hydrological and sediment transport characteristics for the Kosi basin, which covers parts of Nepal India, were analysed to understand spatiotemporal variability hydrology dynamics basin its implications flood hazard dynamics. The study revealed that ∼56% discharge at Chatara (where all major tributaries meet) is contributed from western part even though this constitutes only 34% total area. In contrast, central eastern constitute 57% 8% area but contribute ∼38% ∼16% Chatara, respectively....
The Hindu Kush Himalayas are called the water towers of Asia as they source 10 major rivers and have largest snow ice deposits outside two poles. Water emanating from HKH provides food, energy ecosystem services to up 1.3 billion people. Climate change socio-economic demographic changes put unprecedented pressure on these resources, leading uncertain supplies, increased demands higher risks extreme events like floods droughts. eight articles in this special issue highlight various dimensions...
This article investigates water security in Nepal from the perspective of water-energy-agriculture (food) nexus, focusing on pathways to that originate actions and policies related other sectors. It identifies promoting development Nepal's hydropower potential provide energy for pumping as way improve agriculture. Renewable groundwater reserves 1.4 billion cubic meters (BCM), an estimated available balance 6.9 BCM, could be pumped irrigate 613,000 ha rainfed agricultural land Terai plains,...
Word representation is a means of representing word as mathematical entities that can be read, reasoned and manipulated by computational models. The required for input to any new modern data models in many cases, the accuracy model depends on it. In this paper, we analyze various methods calculating vector space Nepali words postulate based Skip-gram with NCE loss capturing syntactic semantic relationships.
 This an attempt implement paper Mikolov words.
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...
Abstract The selection of general circulation models (GCMs) with high capability to represent the past and likely future climate for a specific geographical location is crucial step assess impacts change on different sectors. This study included pool 105 78 GCMs representative concentration pathways (RCPs) 4.5 8.5, respectively, from Coupled Model Intercomparison Project—Phase 5, applied an advanced envelope‐based approach select Koshi river basin in China Nepal at short‐term (2016–2045),...
This study assesses climate change impacts on the hydrological regime of a river basin and its implications for future irrigation water availability in Koshi River using RCPs 4.5 8.5 over short-term (2016-2045), mid-century (2036-2065) end-of-century (2071-2100) periods. Average flow is projected to increase. Projections average minimum monthly suggest that areas winter wheat monsoon paddy rice could be increased. However, planting period should delayed by one month (July August) capture...
Agriculture plays a critical role in ensuring food and nutrition security, livelihood, rural employment Nepal. Despite substantial investments institutional reforms, irrigation projects have faced consistently low performance. While existing studies shed light on technical aspects of performance, they often focus specific themes rather than holistic evaluations sustainability. This research systematically assesses barriers challenges to effective water management Nepal by assessing ranking...
