Nepal is one of the most vulnerable countries to climate change impacts. Extreme weather events associated with heavy precipitations are principal causes landslides, debris flows and all types floods disasters in country, which by causing tremendous losses life property affects socio‐economic development. Given limited availability knowledge spatio‐temporal distribution precipitation Nepal, this study analyses spatial monthly annual 1‐day extreme their trends utilizing a large number...
Floods pose devastating effects on the resiliency of human and natural systems. flood risk management challenges are typically complicated in transboundary river basin due to conflicting objectives between multiple countries, lack systematic approaches data monitoring sharing, limited collaboration developing a unified system for hazard prediction communication. An open-source, low-cost modeling framework that integrates open-source models can help improve our understanding susceptibility...
Abstract This study aims to assess the accuracy of two satellite‐based precipitation products (SBPPs), that is, Tropical Rainfall Measurement Mission (TRMM)‐based Multi‐satellite Precipitation Analysis (TMPA) and its upgraded version Integrated Multi‐Satellite Retrievals for Global (IMERG), in capturing spatial temporal variation their application extreme events (high‐intensity drought). They were evaluated against 142‐gauge stations from Nepal during 2001–2018. The results show that,...
Abstract The COVID‐19 pandemic has impacted social, economic, and environmental systems worldwide, slowing down reversing the progress made in achieving Sustainable Development Goals (SDGs). SDGs belong to 2030 Agenda transform our world by tackling humankind's challenges ensure well‐being, economic prosperity, protection. We explore potential impacts of on for Nepal. followed a knowledge co‐creation process with experts from various professional backgrounds, involving five steps: online...
West Rapti River (WRR) basin, Western Nepal. Hydrologic modeling requires an accurate precipitation data at a high spatial resolution, which is often limited in many regions of the globe. As complement to ground (gauge) data, satellite-based estimates (SPEs) appear useful. At first, this study evaluated performance three different SPEs, namely i) CHIRPS, ii) PERSIANN-CCS, and iii) IMERG, with respect gauge using event detection quantification indices. Soil Water Assessment Tool (SWAT),...
Natural hazards are complex phenomena that can occur independently, simultaneously, or in a series as cascading events. For any particular region, numerous single hazard maps may not necessarily provide all information regarding impending to the stakeholders for preparedness and planning. A multi-hazard map furnishes composite illustration of natural varying magnitude, frequency, spatial distribution. Thus, risk assessment is performed depict holistic scenario region. To best authors’...
Rapid Urbanization, and other anthropogenic activities, have amplified the change in land-use transition from green space to heat emission built-up areas globally. As a result, there has been an increase land surface temperature (LST) causing Urban Heat Island (UHI) effect, particularly large cities. The UHI effect poses serious risk human health well-being, magnified developing cities with limited resources cope such issues. This study focuses on understanding Kathmandu Valley (KV), Delhi,...
Abstract Owing to unique topographic and ecological diversity, central Himalayan state of Nepal is exposed adverse impacts climate change associated disasters. However, countrywide historical assessment mean extreme temperature changes, a prerequisite for devising adequate adaptation strategies, still lacking. Here, we present comprehensive picture trends across over the 1980–2016 period, based on high‐quality daily observations from 46 stations. Our results suggest that besides winter...
Abstract The study, conducted in western hilly areas of Nepal, inventoried and mapped over 4,222 springs from five different watersheds. study showed that more than 50% the spring sources were found under natural conditions, i.e., open whereas 15% them pond type. Similarly, other was recorded as a concrete structure or tank while 1% determined to be well. Attempts made identify if change water discharge relates rainfall patterns. inter-annual variability analysis shows significant...
Drought is an environmental disaster related to the extremes (on a drier side) in hydrometeorology. The precipitation amount modulates drought Nepalese river basins. It vital for efficient water resources management quantify and understand drought. This paper aims characterize droughts Nepal based on standard index (SPI) rainfall anomaly (RAI) using daily data assess their impacts annual crop yields. We used 41 years (1975–2015) of compute monthly means then indices, namely, SPI RAI, at 123...
Extreme precipitation (rain or/and snow) in upstream areas of the Himalayan region often triggers water and sediment hazards, including flash floods, landslides, debris flow, river damming. These hazards interact with environmental human systems, resulting acute chronic disasters that deleteriously impact economy, infrastructure, livelihoods. As cascading compound become more common region, a holistic approach is needed to understand complex interaction among human, natural, engineered...
Abstract A better understanding of variations extreme precipitation in space and time is essential for hydro‐meteorological research effective management water resources. We used 11 indices, some additional four seasonal based on daily data from 24 meteorological stations West Rapti River basin (WRRB) Nepal during 1986–2015 as the baseline, three future periods (Near Future or NF: 2025–2049, Mid MF: 2050–2074, Far FF: 2075–2099). This study also attempts to correlate streamflow at downstream...
Globally, groundwater resources play a crucial role in supporting livelihoods and sustaining human health. Groundwater recharge is mainly influenced by the spatial distribution of rainfall patterns across basins heterogeneous geology, soil, topographical characteristics. This study evaluates implications variations land-use on level fluctuations Kathmandu Valley, Nepal. We selected analyzed data from thirty-five monitoring wells observed citizen scientists July 2017 to June 2019. Over two...
