of ten or fewer boxes, in any way that appears sensible (not necessarily
as shown in Fig.5.1, which is just for illustration) and supply, if
available, the following information:
(a) For each box, except A: its surface area, average depth and
volume.
For each box, except A: the suspended sediment load (tonnes/m3) and sedimentation rate (tonnes/m2/yr.)

It is appreciated that much of this information will not be available. However, please supply the information needed to obtain estimates, such as
the magnitude and direction of the ocean currents during the different
seasons, and any other information about the movement of the water
masses.

(iii) For Deep Bay and Tolo Harbour (including Tolo Channel), separately,
please supply the surface area, average depth and water volume; and your
best estimate of the suspended sediment load, sedimentation rate and the
water turnover rate for each bay (alternatively the flows, analogous to
the Fs above, into and out of each bay, from and to the open sea). Also,
if available, typical residual tidal velocities for each bay.
