Scour is the number one cause of bridge failures. Scour in
coarse-grained soils (sand, gravel) is relatively well known, but
scour in fine-grained soils (silt, clay) and weak rock is not. In
coarse- grained soils, scour takes place very rapidly and the scour
rate is rarely an issue because one flood is likely to create the
maximum scour depth. In fine- grained soils, the scour process is
much slower, as a result, even after a hundred years; a bridge may
not yet experience the maximum depth of scour. Therefore, in fine-
grained soils it becomes necessary to predict the rate at which
scour takes place. To solve the above problem a new apparatus
called the TEM (TIME EROSION METER) has been proposed after the
studies. At present, the model, and both prototype of this
apparatus have been successfully devised. From the experimental
result of this apparatus, it is expected that this apparatus can be
successfully put in use to measure the erosion rate of both
fine-grained and coarse- grained soils in more rational way than
the present practice.
