Abstract An understanding of climate variability, trends, and prediction for better water resource management planning in a basin is very important. Since the resources Lake Chad (LCB) are highly vulnerable to changing climate, present study, combination trend analysis methods was used examine variability trends period 1951–2015 using observed Climate Research Unit (CRU) data, spectral techniques temperature precipitation CRU data. Eighty-four percent time series indicated extremely strong...

Abstract A comprehensive and reliable assessment of the water resources in China's transboundary river basins is vital for management peaceful development. In this study, we built machine learning (random forest, gradient boosting, stacking) traditional linear models to identify relation between runoff coefficient its influencing factors, including topography, climate, land cover, soil. The cross‐validation results show that greatly outperform model predicting coefficient. High‐resolution...

The Yellow River Basin plays a crucial role in China's socio-economic development and ecological security. growing trend of water consumption driven by anthropogenic activities has posed an increasing number challenges for the sustainable basin. Water demand prediction central part facilitating conservation developing allocation strategies. Hence, model based on concept resources carrying capacity was built to predict with different future scenarios provide reference strategies allocation....

Using National Oceanographic and Atmospheric Administration/Advanced Very High Resolution Radiometer (NOAA/AVHRR) Climatic Research Unit (CRU) climate datasets, we analyzed interannual trends in the growing-season Normalized Difference Vegetation Index (NDVI) China from 1982 to 2011, as well effects of climatic variables human activities on vegetation variation. Growing-season (period between onset end plant growth) NDVI significantly increased (p < 0.01) a national scale showed positive...

The knowledge of water storage variations in ungauged lakes is fundamental importance to understanding the balance on Tibetan Plateau. In this paper, a simple framework was presented monitor fluctuation inland bodies by combination satellite altimetry measurements and optical imagery without any situ measurements. level, surface area, Lake Qinghai were estimated demonstrate framework. Water levels retrieved from ICESat (Ice, Cloud, Elevation Satellite) elevation data lake area derived MODIS...

Abstract The triangle method based on the spatial relationship between remotely sensed land surface temperature ( T s ) and vegetation index (VI) has been widely used for estimates of evaporative fraction (EF). In present study, a universal was proposed by transforming ‐VI feature space from regional scale to pixel scale. retrieval EF is only related boundary conditions at scale, regardless configuration over domain. each are composed theoretical dry edge determined energy balance principle...

Abstract As a fundamental natural resource and strategic economic resource, water resources play key supporting role in the process of social development. In this paper, risk factors influencing carrying capacity (WRCC) were investigated based on theory theory, method for assessment WRCC was proposed. The vulnerability system evaluated by using Fuzzy Comprehensive Evaluation method, hazard calculated comprehensive index, then obtained combining with hazard. China due to climate change,...

Abstract China's water stress and its pressure on food security is a widely recognized crisis. A framework proposed applied at the provincial level to evaluate for production. It based index that accounts deficit between supply aggregate demand of 23 major field crops over study period (1961–2015). The estimated method recommended by Food Agriculture Organization United Nations. composed rainfall irrigation. Consequently, both rainfed irrigated agriculture evaluated in our research,...

With abundant resources in the wetland, Yellow River Delta provides important habitats for various kinds of rare bird species. However, due to climate change and human water withdrawal activities, no-flow events occurred frequently since 1970s, resulting serious wetland degradation biodiversity losses. Ecological supplement has been regarded as one most effective measures cope with these environmental problems. Accordingly, how much is required ecological restoration becomes an essential...

Abstract. This research explores the rainfall-El Niño-Southern Oscillation (ENSO) and runoff-ENSO relationships examines potential for water resource forecasting using these relationships. The Southern Index (SOI), Niño1.2, Niño3, Niño4, Niño3.4 were selected as ENSO indicators cross-correlation analyses of precipitation runoff. There was a significant correlation (95% confidence level) between during three periods: January, March, from September to November. In addition, monthly streamflow...

Abstract. In this study, the impacts of El Niño–Southern Oscillation (ENSO) on daily precipitation regimes in China are examined using data from 713 meteorological stations 1960 to 2013. We discuss annual precipitation, frequency and intensity rainfall events, extremes for three phases (eastern Pacific Niño – EP, Central CP, La Niña LN) ENSO events both developing decaying years. A Mann–Whitney U test was applied assess significance anomalies due ENSO. Results indicated that each had a...
