Abstract

The East River basin is the major source of water supply for megacities in the Pearl River Delta and Hong Kong Intensifying development of water resources and reservoirinduced hydrological alterations negatively affect ecological hydrological requirements In this study hydrological alterations and environmental flow variation are determined Results indicate that 1 multiday maxima have reduced while multiday minima have increased due to hydrological regulations of water reservoirs 2 hydrological regimes of the East River have also been severely affected by hydropower generation leading to a greater frequency of high and low pulses of lesser duration and these effects are increasingly evident from the upper to lower East River basin 3 owning to the water being released rapidly for hydropower generation or flood protection the number of hydrologic reversals have increased after reservoir operations also with increasing rise and fall rate and 4 the alteration of three different types of environmental flow components have been shown in the study which can be used to support the determination of environmental flow requirements in the East River basinThis work was financially supported by The National Natural Science Foundation of China Grant No 41071020 Program for New Century Excellent Talents in University NCET and is fully supported by a grant from the Research Grants Council of the Hong Kong Special Administrative Region China Project No CUHK441313 Our cordial gratitudes should be extended the editor Prof Dr George Christakos and two anonymous reviewers for their professional comments and revision suggestions which are greatly helpful for further improvement of this manuscript
