HULHULE-MALE’ BRIDGE PROJECT

EIA for the proposed Hulhule-Male’ Bridge Project
northeast coast of Malé Island is about 0.10~0.15 m/a. The depositional range from the works is
expected to be within about 1.5 km on both sides of the construction area.
Siltation intensity is expected to decrease annually, gradually reaching a balance between silting
and scouring.
6.1.4 Impacts on Surfing Area
The southeast corner of Malé where the bridge is proposed is a popular surfing area among
locals and tourists. The construction of the may impact the wave environment in this area.
Nanjing Hydraulic Research Institute was entrusted to survey the wave field in the area before
and after construction of the bridge through physical model experiments.
The experiment was carried out in the large wave harbor basin of River and Harbor Institute of
Nanjing Hydraulic Research Institute; the harbor basin is 52 m in length, 70 m in width and 1.2
m in depth. The integral model experiment was conducted in an area with 50 m in width and 27
m in length separated out from the harbor basin. The area is equipped with an irregular wave
generator at one end to produce required simulative wave elements via an automaticallycontrolled
computer. The wave generator produces regular and irregular wave as required. Wave
height measurement is measures using wave height gauge, DS30 multifunctional automatic
acquisition system is used for gathering data, and the data processing is controlled and analysed
by the computer.
The geometric scale of model is 1:80. The picture of topography simulation is presented in
Figure 6.3. Bridge model picture and pier picture is presented in Figure 6.4 and Figure 6.5
respectively.
