Hi Satjajeet-- I'm curious if you could give a few sentence layman's terms explanation of your paper and what it means to the clean power utilities out there?

Hi Matt , Sure - In hydropower projects, tailrace surge shafts need to be applied after the turbines, if the spent water is conveyed under pressure through a long tailrace tunnel into the recipient.

It has been observed that in the course of determining the sizes of the tailrace surge shafts to dampen the minimum downsurge, many times, the designer may end up with larger sizes, especially for a long pressurized tailrace system. There is no specific documented procedure that the designer can follow to optimize the tailrace surge shaft to dampen the minimum downsurge. Optimization is usually performed based on the wisdom of the designer. Often times, the steps carried out in the optimization are not described in the relevant reports. The author carried out numerous transient analyses to determine the steps to be carried out to optimize tailrace surge shafts and efficiently dampen the minimum downsurge. 

Since hydropower projects are 100 % renewable energy and almost 98% of Global grid storage is done through Pump Storgae Hydropower project. So this paper will be useful in development of optmized hydropower projects for the development of clean power utilities.
