The objective of this study was to analyze the response runoff in area yield upstream Shiyang River basin climate change and promote sustainable development regional water resources ecological environment. As biggest tributary River, Xiying is only hydrological station (Jiutiaoling) that has provincial natural river can achieve long time series monitoring data basin. obtained from representativ...

The natural runoff mechanism of the Dawen River, main tributary lower Yellow has been stressed in recent years as a result human activity, and hydrological situation changed dramatically. In this paper, various statistical methods such Mann–Kendall nonparametric test, cumulative anomaly, ordered clustering, sliding T rainfall–runoff double-cumulative curve were used to study evolution character...

one of the most important hydrological time series task is to determine if there is any trend in the data and how to achieve stationarity when there is nonstationarity behavior in data. detecting trend and stationarity in hydrological time series may help us to understand the possible links between hydrological processes and global climate changes. in this study yearly, monthly and daily stream...

This study concentrates mainly on the 12-year time trends of annual average ion concentrations in bulk precipitation from 10 Estonian monitoring stations. Trends revealed by the nonparametric Mann-Kendall test mostly show a statistically significant decline and, according to the order of ion decline per year, three groups of stations could be differentiated: stations directly affected by an ind...

BACKGROUND The workers who are working in the open and warm environments are at risk of health effects of climate and heat changes. It is expected that the risk is increase with global warming. This study aimed to investigate the changes of Wet Bulb Globe Temperature (WBGT) index in the past and to predict their trend of future changes in Tehran, capital of Iran. METHODS The meteorological da...
