Abstract
The main works of this year are continue to
monitor the erosion and rainfall data of
drainage area of weir NO1 and NO2 of
Fushan Long Term Ecological Site.
According to previous experience, it was
very difficult to collect the bed load data in
weir NO2 especially during Typhoon perioids.
Total station was applied to measure the
micro-relief of channel for calculation of
sediment yields. G.I.S. software is also used
for calculation on the total volume of the bed
load. There is about 60.78 cubic meters
deposit in the period from June 1999 to
March 2000. Sediments deposition change 1
the micro-relief of channel dramatically
according to the detailed surveying. In the
future, repeated surveying could be a good
way for calculation and evaluation of
sediments in weir NO 2.
