Present work deals with a critical study on hydraulic jump in stilling basin with vertical end sill. The objective of present study is to assess the effectiveness of vertical end sill and its position on control of length of stilling basin to economize the cost of stilling basin. The work has been carried out based on reliable data collected from published work of various investigators on hydraulic jump in stilling basin with vertical end sill. The effectiveness of vertical end sill in reducing the length of hydraulic jump (i.e. length of stilling basin) was critically examined from the available data. The study reveals that there is a significant dissipation of energy and reduction in length of hydraulic jump due to the presence of vertical end sill. It has been found that the sequent depth ratio and length of the stilling basin are greatly affected by sill height and position. This study is useful in practical field in the economical design of stilling basin.
