Due to the rapid population growth in Taipei Basin, residents are
fighting for land with rivers, and building embankments is a reality that
cannot be changed. The special landform of a basin and fighting for land
with water increases potential risk. The uncertain effects of climate change
are also disadvantageous to the basin’s future development, and will
directly or indirectly impact the functionality and safety of flood
prevention facilities. This paper examines the effect of past typhoon and
flooding events, as well as the effectiveness of flood prevention facilities
on economic development and population changes along the riverbank.
After collecting data on typhoon and flooding events as well as the
construction of flood prevention facilities through literature review, the
paper summarizes the scope of flooding, flood levels at Taipei Bridge,
construction of flood prevention facilities, Taipei’s flood prevention plan,
and remediation of Keelung River. This paper then analyzes the
correlation between the data, results are follows: the flood level at Taipei
Bridge significantly declined from 1963 to 1986, but increased after 1986;
the range of flooding in Taipei gradually decreased after 1963. Flood level
rise and range of flooding are mainly affected by rainfall intensity,
duration and distribution. To understand the effectiveness of flood
prevention facilities, this paper examines the correlation between typhoon
and flood disasters and the construction of flood prevention facilities, and
IV
also considers changes in riverway erosion and deposition, land
subsidence, and land development.
Changes in population along the riverbank are found through
demographics websites, and the correlation with flood prevention facilities
is found based on the timetable of flood prevention projects (1953, 1963,
1973, 1981, 1991, 2001, 2014). This paper further discusses economic
development, flood prevention protection standards, disaster prevention
and relief, and water control measures.
The abovementioned analysis results are provided as a basis for future
research, and for the public to understand past disasters and flood
prevention facilities. Charts offer analysis of the effectiveness of flood
prevention facilities. Finally, this paper can serve as reference for the
formulation, review and evaluation of policies for flood prevention
facilities. | en_US |
