| Summary: | Flood has been an annual occasion that has occured in Kesawan, whereas this area
counted as heart of the capital city of North Sumatera, Medan. It is also known as
the places for many historical buildings. The flooding caused by the insufficient of
drainage channel to hold the water on the surface flow. One of the elements
affecting the surface flow discharge is the availability of RTH in Kesawan still
accounted under 30%. Besides accomodating the social activities’ needs, RTH
holds the control of ecological balance. In accordance to that, the purpose of this
thesis is to plan RTH within Kasawan cultural heritage to mitigate flood. This thesis
use rational method to count the peak discharge of rainfall intensity, and sustainable
management of runoff water by applying bioswales as a channel to minimize runoff
water from RTH to drainage channels. The effort to enhance RTH intended to
follows the characteristic and social needs nearby (city park through green wall).
Peak discharge from the intensity of rainfall of 10 years scale plan is 122,40
m3/second. Whilst bioswales adaption applied, runoff water discharge could be
handled with a length of 2.565m bioswales. By using the green factor method from
the RTH, predictical more than 10% of green space is obtained |
