Abstract. The middle route of South-To-North Water Diversion in China transfers water from the Han River and Han-To-Wei Water Diversion project of Shaanxi Province will transfer water from the Ziwu River, which is a tributary of the Han River. In order to gain a better understanding of future changes in the hydrological conditions within the Ziwu River basin, a Mann–Kendall (M–K) trend analysis is coupled with a persistence analysis using the rescaled range analysis (R/S) method. The future change in the hydrological characteristics of the Ziwu River basin is obtained by analysing the change of meteorological factors. The results show that, the future precipitation and potential evaporation are seasonal, and the spatial variation is significant. The proportion of basin area where the spring, summer, autumn and winter precipitation is predicted to continue increase is 0.00, 100.00, 19.00 and 16.00 %, meanwhile, the proportion of basin area that will continue to decrease in the future respectively will be 100.00, 0.00, 81.00 and 74.00 %.The future potential evapotranspiration of the four seasons in the basin shows a decreasing trend. The future water supply situation in the spring and autumn of the Ziwu River basin will degrade, and the future water supply situation in the summer and winter will improve. In addition, the areas with the same water supply situation are relatively concentrated. The results will provide scientific basis for the planning and management of river basin water resources and socio-hydrological processes analysis.

The Future

The Petroleum Administration for War was concerned with geophysical operations in foreign countries because such work had a direct bearing upon the possibility of discovering new fields and finding new reserves of petroleum. At the beginning of 1945 no one could confidently predict the time when war requirements for petroleum would cease and it was necessary to look ahead for an indefinite period in planning for future oil production. New fields in accessible locations were an important element in the future petroleum supply situation.

Significance The Dail convened on March 10 to elect a taoiseach (prime minister), but no nominee was able to attract the support of anything close to a majority. Impacts Ireland's problems including the decline in public services are unlikely to be addressed while a caretaker government is in place. Substantial delays in forming a new government could raise Irish bond prices. The future of Irish Water, a body set up to deal with water supply problems whose abolition was demanded by the opposition, is uncertain. The crisis may bring about a long-promised reform of the way the Dail operates, giving it a larger and more constructive role.
