| Summary: | Komodo International Airport mainly serves passenger movement through air transportation
in Flores, East Nusa Tenggara. To maintain continuity of airport operations and ensure the
safety of passengers, airport areas, notably flight priority areas should not be flooded.
Therefore, a well-designed drainage system is needed.
The design process is carried by first collecting and processing secondary datas as well as
designing channel tracts. Subsequently, hydrology and hydraulic analysis is done to obtain
the design flow rate along with the dimensions of the drainage channels. The airport is about
1.5 km from the coastline, so an analysis of tidal influences is needed to determine the legth
of backwater. Finally, an analysis is conducted to ascertain that runoff from the final canal
can be channeled into the river as a water final disposal site even when it is on a state of
flood stage.
From the calculation, it is obtained a discharge flow rate of 6.75 m3/s and a final channel
with 1.7 m of height and 0.85 m of width. Also, it can be seen that there is a backwater with a
length of 67.50 m so it is ensured that the flow does not affect the airport drainage system.
Flood water level is measured as high as +61.54 from the mean sea level, still lower than the
base elevation of the designed final channel.
