摘要:The frequency of drought occurring in the Luanhe River basin in China has increased since 1965. The severe droughts are mainly influenced by the negative phase of Arctic Oscillation (AO) and the 12-month time-lag La Niña events. In this study, we investigate the mechanism o...

摘要:Abstract(#br)The Luanhe River Delta is located at the northern coast of the Bohai Bay, which was an enclosed sea. In 1915, the Luanhe River changed course to its present position, and has since developed a typical fan-shaped delta under fluvial-wave interaction. Owing to the wate...

摘要:... In this paper, we evolve a probabilistic forecasting model, which forecasts transition probabilities from a current Standardized Precipitation Index (SPI) value to a future SPI class, based on conditional distribution of multivariate normal distribution to involve two large-scale climatic indices at the same time, and apply the forecasting model to 26 rain gauges in the Luanhe River...

摘要:Abstract(#br)The water cycle and water resources within river basins under changing environmental conditions undergo profound changes, which have significant effects on the water environment of the river. Owing to the water resources demanded for economic and social development, ...

摘要:... To propose a suitable drought index for drought assessment, the Luanhe river basin in the northern China was selected as a case study site. Based on the Principal Component Analysis of precipitation, evapotranspiration, soil moisture and runoff, the three latter variable...

摘要:Abstract(#br)The Luanhe River Source Area belongs to typical semi-arid, agro-pastoral ecotone of North China. It is very important for the prevention and treatment of soil erosion in North China to analyze and evaluate quantitatively the recent 30-year changes in the process of s...

摘要:Abstract(#br)The decrease of runoff in the Luanhe river basin, which caused water crisis in Tianjin for several times, was investigated using discharge data covering the period 1956–2002. The data from the differential integral curves of the annual runoff indicate that the d...
