Abstract

In Laksda Adisucipto Road, especially South of Nologaten Area, inundation frequently happened. Analyzing drainage canal capacity is conducted to identify existing drainage condition due to inundation problem. The analysis is done by
comparing design discharge in 2, 5, and 10 years return period with existing.discharge from segments area and research area. Result of segments area discharge is 14, 15, and 16 segments are inadequate in 2, 5, and 10 years return period.Research area discharge result shows that research canal is inadequate to accommodate water from research area in 2, 5, and 10 years return period. Based on result combined from both calculation, infiltration wells and drainage canal renovation can be implemented to solve the inundation problem. Infiltration wells are able to be placed in 11 segments area. Drainage canal renovation result shows
increasing of canal dimension can be done in one trajectory segment (E2, F1, F3, and F5 segments) and research canal.
