Abstract: Wind wave backup is one of the main factors to be considered in the design of upper reservoir of sea water pumped storage power station. In this paper, a series of model tests are carried out in wind tunnel flume to test the formation and evolution characteristics of high-frequency wind waves in small water area and its influencing factors, study the corresponding law of wind wave run-up, and put forward the calculation method. The results show that the characteristics of wind waves formed by different wind speed levels are not the same, and small amplitude fluctuations are formed in the test water area under the condition of low wind speed, Under the condition of high wind speed, the characteristics of wind wave will change to low frequency and large amplitude wave with the increase of blowing distance, and the characteristic parameters of wind wave will not be significantly affected when the water depth is not too shallow; The vertical component of wind wave induced run-up increases with the increase of wind speed. After the full development of wind wave, the slope and water depth will not have a significant impact on the wind wave run-up. Based on this, the calculation formula of wind wave run-up is put forward. Compared with the experimental data, the accuracy is good. Relevant results can strongly support the design of upper reservoir of seawater pumped storage power station.
