Evapotranspiration (ET) plays a critical role in linking the water and energy cycles but is difficult to estimate at regional basin scales. In this study, we present worldwide evaluation of nine ET products (three diagnostic products, three land surface model (LSM) simulations reanalysis-based products) against reference (ETwb) calculated using balance method corrected for storage change an annual time scale over period 1983–2006 35 global river basins. The results indicated that there was...
Abstract Lake water storage change (Δ S w ) is an important indicator of the hydrologic cycle and greatly influences lake expansion/shrinkage over Tibetan Plateau (TP). Accurate estimation Δ will contribute to improved understanding variations in TP. Based on a balance, this study explored for Selin Co (the largest closed TP) during 2003–2012 using Water Energy Budget‐based Distributed Hydrological Model (WEB‐DHM) together with two different evapotranspiration (ET) algorithms Penman‐Monteith...
Rivers act as a source of fresh water for terrestrial life, yet the discharges are poorly documented since existing direct observations inadequate and some observation stations have been interrupted or discontinued. Discharge estimates using remote sensing thus great potential to supplement ground observations. There methods established estimate discharge based on single parameter derived relationships; however, they limited specific sections due their empirical nature. In this study, we...
Abstract Snow and frozen soil are important factors that influence terrestrial water energy balances through snowpack accumulation melt freeze‐thaw. In this study, a new land surface model (LSM) with coupled snow physics was developed based on hydrologically improved LSM (HydroSiB2). First, an energy‐balance‐based three‐layer incorporated into HydroSiB2 (hereafter HydroSiB2‐S) to provide description of the internal processes pack. Second, universal simplified HydroSiB2‐S depict freezing...
Abstract The Third Pole experiences accelerated glacier retreating particularly in the eastern‐Himalaya, coinciding with a decrease of monsoon‐precipitation early 21st century. extent to which vanishing abundant maritime glaciers buffer declining precipitation‐runoff remains unclear. Here, state‐of‐the‐art enthalpy‐based distributed cryosphere‐hydrology model and first‐hand hydrometeorology observations at Motuo (latest accessible Chinese county), we carefully examine Yarlung Zangbo basin...
Abstract With the increasing pressure from population growth and economic development, northern China (NC) faces a grand challenge of water scarcity, which can be further exacerbated by climatic societal changes. The South‐to‐North Water Diversion (SNWD) project is designed to mitigate scarcity in NC. However, few studies have quantified impact SNWD on within context changes its potential effects agricultural food region. We used supply stress index (WaSSI) quantify environmental change NC...
Originating from the southern slope of Himalaya, Karnali River poses a high flood risk at downstream regions during monsoon season (June to September). This paper presents comprehensive hazard mapping and assessments in region basin for different return-period floods, with aid HEC-RAS (Hydrologic Engineering Center’s Analysis System). The assessment was conducted on ~38 km segment Chisapani Nepal–India border. To perform hydrodynamic simulations, long-term time series instantaneous peak...
Abstract. As the largest river basin of Tibetan Plateau, upper Brahmaputra River (also called “Yarlung Zangbo” in Chinese) has profound impacts on water security local and downstream inhabitants. Precipitation is mainly controlled by Indian summer monsoon westerly key to understanding resources available basin; however, due sparse observational data constrained a harsh environment complex topography, there remains lack reliable information basin-wide precipitation (there are only nine...
Abstract The Tibetan Plateau (TP) contains the largest permafrost region in mid–low latitudes and area of glaciers outside polar regions. In recent decades, this has experienced vegetation greening (e.g., increasing leaf index) due to climate change. As exorheic river on TP, Upper Brahmaputra Basin (UBB) is very sensitive change, experiencing humidifying significant warming. study, we investigated spatiotemporal variability frozen ground over last four decades UBB explored how these changes...
Drought is a natural disaster with severe global agricultural and economic impacts. Accurate drought indices are needed for improved assessment monitoring; however, most existing poorly represent due to complex interactions among meteorological factors, crop soil conditions. Here, we compute an integrated condition index (IDCI) based on the 3-month standardized precipitation evapotranspiration (SPEI3), vegetation cover (VCI) moisture (SMCI). We apply IDCI monitoring in Xinjiang, China. After...
Abstract The water resources of the Third Pole (TP), highly sensitive to climate change and glacier melting, significantly impact food security millions in Asia. However, projecting future spatial‐temporal runoff changes for TP's mountainous basins remains a formidable challenge. Here, we've leveraged long short‐term memory model (LSTM) craft grid‐scale artificial intelligence (AI) named LSTM‐grid. This has enabled production hydrological projections seven major river TP. LSTM‐grid...
Abstract Since the 20th century, temperature on Qinghai–Tibetan Plateau (QTP) has increased at a rate of 2–3 times that global warming. Consequently, soil and active layer thickness have also increased, which directly caused severe degradation frozen ground QTP. Using hydrological model driven by climate vegetation forcing, spatial temporal changes in hydrothermal characteristics Upper Yellow River Basin (UYRB) from 1960 to 2019 were modeled mechanism was analyzed. During past six decades,...
Abstract Cryosphere plays an important role in cold‐region (e.g., Tibetan Plateau) hydrological processes under climate change, and thus cryosphere physics should be carefully represented the modeling. In this study, based on Water Energy Budget‐based Distributed Hydrological Model (WEB‐DHM), we have further improved processes, by incorporating enthalpy‐based coupled snow frozen ground (hereinafter WEB‐DHM‐SF), comprehensively evaluated at upper Yangtze River Basin widespread cover ground....
Soil temperature is a key parameter in the soil–vegetation–atmosphere system. It plays an important role land surface water and energy cycles, has major influence on vegetation growth other hydrological aspects. We evaluated accuracy of soil profiles from Global Land Data Assimilation System (GLDAS) using nine observational networks across world aimed to find reliable global profile dataset for future ecological studies. In general, data generated by Noah model driven GLDAS forcing...
Abstract In distributed hydrological modeling, surface air temperature ( T ) is of great importance in simulating cold region processes, while the near‐surface‐air‐temperature lapse rate (NLR) crucial to prepare (when interpolating from site observations model grids). this study, a biosphere with improved snow physics (WEB‐DHM‐S) was rigorously evaluated typical cold, large river basin (e.g., upper Yellow River basin), given mean monthly NLRs. Based on validated model, we have examined...
Streams play an important role in linking the land with lakes. Nutrients released from agricultural or urban sources flow via streams to lakes, causing water quality deterioration and eutrophication. Therefore, accurate simulation of streamflow is helpful for improvement lake basins. Lake Dianchi has been listed 'Three Important Lakes Restoration Act' China, degradation its great concern since 1980s. To assist environmental decision making, it assess predict hydrological processes at basin...
