Some computations on Seiches in Lake Fife at Khadakvasla, poona

Abstract

Chrystal has worked out a number of formulae for seiche-periods under various assumptions regarding the shape of the bed of the lakes where these seiches are excited. Based upon his method, periods of seiches that could be excited in Lake Khadakvasla have been computed, The period of the uninodal, binodal, trinodal and quadrinodal seiches are obtained approximately  1 ¼ hours, 2/3 of hour 5/12 of an hour  and 1/3 of an hour respectively.

Hidaka's method of solving Chrystal's differential equation by the use of the theorem of Ritz in the calcuius of variation, has been used for the case, where the like's bottom is assumed parabolic. The uninodal period there by worked out or Lake Fife comes out to be 1 1/4 hours.

For a test of these computed values computed values, experimental observations are required and it is suggested that a suitable limnograph be set up for the purpose of recording these oscillations when natural phenomena excite them.
