Variation and trend prediction of the mountain runoffs of the trunk streams of the Shule River basin, Hexi Corridor
Based on the measured and surveyed hydrologic data of the Shule River basin, Hexi Corridor from 1956 to 2013, monthly and annual variations of mountain runoffs of the trunk streams of the Shule River were statistically analyzed, and Kandel rank correlation method was used to inspect runoff variation in the basin.The results show that the mountain runoff averaged over 1956-2013 is 11.6679 × 108 m3;floods concentrate from June to September, when the runoff accounts for 35.9 ％ ～ 78.7 ％ of the annual runoff;groundwater recharge accounts for 40.46％ of the runoff on the average;annual variation of the mountain runoff is continuously increasing with a relatively small rate.It is predicted that in the next 5 years (2014-2018) the annual average mountain runoff of the trunk streams of the Shule River would increase to 13.01 × 108 m3.
