| Zusammenfassung |
| Due to rapid urbanization and climate change, the frequency of concentrated heavy rainfall
has increased, causing urban floods that result in casualties and property damage.
As a consequence of natural disasters that occur annually, the cost of damage in
Korea is estimated to be over two billion US dollars per year. As interest in natural
disasters increase, demands for a safe national territory and efficient emergency
plans are on the rise. In addition to this, as a part of the measures to cope with the
increase of inland flood damage, it is necessary to build a systematic city flood
prevention system that uses technology to quantify flood risk as well as flood forecast
based on both rivers and inland water bodies. Despite the investment and efforts to
prevent landside flood damage, research and studies of landside-river combined
hydro-system is at its initial stage in Korea. Therefore, the purpose of this research
introduces the causes of flood damage in Seoul and shows a flood forecasting and
warning system in urban streams of Seoul. This urban flood forecasting and warning
system conducts prediction on flash rain or short-term rainfall by using radar and
satellite information and performs prompt and accurate prediction on the inland
flooded area and also supports synthetic decision-making for prevention through
real-time monitoring. Although we cannot prevent damage from typhoons or localized
heavy rain, we can minimize that damage with accurate and timely forecast and
a prevention system. To this end, we developed a flood forecasting and warning
system, so in case of an emergency there is enough time for evacuation and disaster
control.
