| dc.description.abstract | In this final project, what is evaluated is the condition of the drainage system
on Jalan Mapilindo, Medan Perjuangan District. This final project was carried out
because of flooding problems that occurred in the road area due to reduced
absorption areas, high rainfall intensity, and insufficient channel dimensions. So an
evaluation is carried out regarding the capacity of the drainage channels to find out
whether the drainage channels are sufficient or not to accommodate
rainwater discharge.
This final assignment is an evaluation in nature where the research data is
secondary and primary data, then after the data is collected, then analyze the
hydrology and hydraulics data. In the results of the rainfall analysis used to calculate
rainfall intensity is the Log Pearson III distribution rainfall value with a return
period of 5 years. To find the flood discharge, the plan uses a rational method. Based
on the results of a comparison of the existing capacity of the channel and the
planned flood discharge, it is known that the existing channel cannot accommodate
the planned flood discharge, causing water to overflow from the drainage channel
and inundate the surrounding area. To overcome this, it is necessary to re-plan the
channel dimensions. | en_US |
