| dc.description.abstract | The drainage system of Pepe Hulu River is a system facing waterlogging
issues. Situated in the Banjarsari and Jabres Districts, the Pepe Hulu River
Drainage System experiences a high influx of water that overwhelms its
channels, resulting in water accumulation. Hence, a study of the drainage
channels is necessary, along with solutions to address the waterlogging in
the Districts Banjarsari and Jabres. Drainage channel simulation is
conducted using the HEC-RAS application to model the channels, their
cross-sectional conditions, and potential solutions. Data collection involves
gathering information from relevant agencies. The method used to calculate
the design discharge is rational, involving channel modeling using HECRAS. Channel analysis is performed to determine the channels' capacity.
Solutions involve structural planning for the channels experiencing
waterlogging to reduce it. The research findings indicate that several
channels in the the system of Pepe Hulu River drainage system overflow due
to their capacity being smaller than the planned discharge. To address this
issue, normalization of the channels and the construction of infiltration
wells are proposed solutions. Analysis reveals waterlogging in channels
H2, H3.1c, H4, H6, H7a, H7b, and H10, necessitating alternative solutions.
The proposed solution involves altering channel dimensions until the
planned discharge can be fully accommodated, alongside constructing
infiltration wells with a depth of 2.2 m and a diameter of 1 m for every 36
m2 of roof area, with a reduction discharge rate of 0.00028 m3/s for each
infiltration well. | en_US |
