Ferpecle in Switzerland. The study was able to confirm
that central bar deposition, transverse bar conversion,
lobe deposition, chute cut-off, lobe dissection, channel
constriction and channel choking were all

processes influencing morphologic development in the
reach (Figure 14.9). Perhaps of more importance were
the results obtained concerning the impact of survey fre-
quency on sediment budgeting. It is strikingly clear from
Figure 14.9 that more infrequent survey fails to capture
