Evaluasi Dimensi Saluran Drainase Di Parit Indah Jalan Parit Indah Kota Pekanbaru
ABSTRACT
Stagnant water or flooding often occurs in several regions of Indonesia. The
things that affect the occurrence of flooding vary widely. One of them can be seen
from the dimension of the channel cross section. Making the channel section must
be in accordance with various kinds of calculations, such as rainfall, rainfall
intensity, slope and other calculations. The object of the case study conducted by
the author is determining the cross-sectional dimensions of the drainage on St.
Parit Indah, Pekanbaru. Ineffective cross-sectional channels can be recalculated
according to the planned rainfall data calculation based on available data for a
maximum of 10 years, rainfall intensity data, DTA analysis, channel shape design,
determining the slope of the channel, rain intensity, peak discharge using a
rational method, and finally determining the dimensions of trapezoidal concrete
material with a manning coefficient (n) = 0,0013; guard hight (w) = 0,264 m,
water level (h) = 0,883 m, bottom channel width (B) = 4,00 m, upper channel
width (B) = 8,00 m and channel depth (H) = 1,147 m.
Keywords: section dimensions, trapezoidal channel section.
