MR. ROBERT GURNEY ON THE TIDES OF 
X. 
THE TIDES OF THE RIVER BURE 
AND ITS TRIBUTARIES. 
By Robert Gurney, M.A. 
Read 28 th February, 1911. 
Much importance has, of late years, been attached to the 
question of the present tidal condition* of the Bure and its 
tributaries, and, in view of the rather vague ideas which seem 
to prevail with regard to this matter, it seems advisable to 
set forth such knowledge as has been gained concerning the 
tides through work done by the Sutton Broad Laboratory. 
The following notes do not pretend to completeness, nor 
do they lay claim to originality. Every one who has visited 
the Broads has, in my experience, very definite ideas with 
regard to the tides, so that all that is desired is to communicate 
the results of observations made with such accuracy as has 
been found possible, in order to provide material for the 
support or removal these of ideas. These observations have 
been made chiefly by one not specially trained to the task 
and acutely conscious of its difficulties, and they are intended 
to serve as a supplement to Mr. Innes’ paper on the Chemistry 
of the Waters of the Bure, so that the two papers together 
may give a description of the tides which should be of interest 
to all who know the Norfolk Broads. 
The observations of the rise and fall of the water have been 
made with a Richard recording tide gauge, which is a portable 
* There is a general consensus of opinion that the range and influence 
of the tides have been greatly extended by the dredging, in recent years, 
of Yarmouth Harbour and of the Knoll.
