- Abstract:
-
Spring snow-melting flood and seasonal froze humidity change were analyzed based on the seasonal froze soil moisture, snow depth and runoff data from 2009 to 2012 in the Juntang River Basin in the north slope of Tianshan Mountain. The results indicate: (1) snowmelt flood flow has a close relationship with snow depth and seasonal froze soil moisture, and snowmelt flood peak depends on snow depth and seasonal froze soil moisture; (2) 10 cm range of seasonal frozen soil surface moisture will result in the generation of snowmelt flood, while seasonal froze soil below 10 cm moisture dramatic change caused snowmelt water infiltration and weaken the flood peak, lower peak. Seasonal frozen soil moisture change transforms the way of underling surface runoff, the study on effect of seasonal soil humidity change to snowmelt flood has an important significance to spring snowmelt flood forecast.
