H. AMIR MACHMUD STREET CIMAHI CITY WEST JAVA PROVINCE JF - GEOMATE Journal JA - INTERNATIONAL JOURNAL OF GEOMATE VL - 16 IS - 57 SE - Articles DO - UR - https://geomatejournal.com/geomate/article/view/2869 SP - 195-200 AB - <p>Nowadays, water inundation often occurs in some areas in Cimahi. One of the highest <br>inundation occurred on Jenderal H. Amir Machmud street with a depth of 100 cm with the receding time 1 –<br>2 hours. This condition causes a very high level of congestion, so it can cut access from Bandung to Cimahi. <br>In addition, of course, this condition can cause damage to the road itself. Using a drainage cross-section data <br>from Cimahi government and field measurement, rainfall data, topographic map, and land use data the <br>existing drainage capacity can be calculated by manual and HEC-RAS. Based on the result of manual <br>calculation, there is total debit in drainage channel on 2 year return period is 2.86 m3<br>/sec, 5 year return period <br>is 3.59 m3<br>/sec, and a 10 year return period is 4.08 m3<br>/sec with the existing channel debit is 2.02 m3<br>/sec so that <br>cause the water overflows from the channel. The Cilember River flows with a large discharge 2 years period <br>is 59.64 m3<br>/sec, a 5 year return period is 93.74 m3<br>/sec, and 10 years 118.30 m3<br>/sec crossing Amir Machmud <br>Street affecting high inundation at the site of the review. To solve the problem, some models of solution have <br>been made in the form of new box culvert drainage channel planning with the smallest dimension is 2 × 2 m <br>and biggest dimension is 3 × 3 m. Meanwhile, to handle the overflow of water from Cilember River planned <br>2 pieces of culverts with dimensions 2.5 × 2.5 m.</p> ER -
