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...

Climate change has a complex effect on snow at the regional scale. The change in snow patterns under climate change remains unknown for certain regions. Here, we used high spatiotemporal resolution snow-related variables simulated by a weather research and forecast model (WRF) including snowfall, snow water equivalent and snow depth along with fractional snow cover (FSC) data extracted from Mod...

Dramatic changes in hydrological factors in the Weihe River basin are analysed. These changes have exacerbated ecological problems and caused severe water shortages for agriculture, industries and the human population in the region, but their drivers are uncertain. The Mann-Kendall test, accumulated departure analysis, sequential clustering and the sliding t-test methods were used to identify t...

abstract in this research the thermal stratification of the water in the torogh dam basin and the resulted changes in its quality with respect to temperature, salinity and dissolved oxygen was investigated using the dynamic reservoir simulation model. the results indicated that in wet years such as 1998, when the average annual precipitation and the resulted inflows to the basin is higher than ...

The Laohahe basin is one of the typical semi-arid regions in Northeast China. Quantitatively estimating contributions human intervention and climatic variability on runoff changes this region will help enhance understanding local hydrological mechanisms provide an effective reference for water resources planning management other world. non-parametric Mann–Kendall test was used to analyze tempor...

The Chishui River Basin is located in the bordering area of Yunnan, Guizhou and Sichuan provinces, which serves as an important ecological barrier upper reaches Yangtze River, plays a leading role preserving natural environments, protecting water resources, maintaining soil functions. However, eco-environmental quality basin has encountered serious challenges recent years, conflict between prot...

zayanderoud basin is one of the important agricultural areas in country level because of climatic variety and resuscitative water of zayanderoud river. since frost phenomenon especially late spring frost incurs great damages on fruit trees and agricultural products of this region, it is necfessary to study frost in this basin.in this research, the intensity of frost during cold period and sprin...
