4 San Bartolome, San Nicolas, Ilocos Norte. This study proposed a drainage system
plan that can cater check capacity and prevent flooding in the area. The data gathering
procedure of this study covered three main segments: obtaining rainfall data, elevation
model, and CDRA report during typhoon Egay, mapping of the elevation model, and
simulation and validation of simulated data from actual conditions using EPA-SWMM.
In analyzing the existing drainage system, particularly the flooded areas, the surface
runoff was evaluated. Conduit dimensions and slopes that are inefficient to contain
water runoff are also assessed through EPA-SWMM software using the 25-year return
period. In the design of proposed drainage system, rerouting, modification of conduit
dimensions, and incorporation of storage tank and pump link were piloted.
Simulation results of the existing drainage system showed that 5 conduit links
surpassed their capacity, leading to localized flooding at those areas. Localized
flooding had a cumulative discharge volume of 72,244 cubic meters throughout the
observation period of 3 days. Additionally, 19 out of 38 conduits are insufficient in
catering water runoff making allowance for freeboard. Drew on the assessment of the
existing drainage system through simulation, six (6) trials of conduit dimension
adjustments were made. Successful trial results showed that all 49 conduits were
adequately calibrated to accommodate runoff water while maintaining sufficient
freeboard.
Based on the analysis of the existing and design of the proposed drainage
system, the researchers concluded that particular existing conduits were not adequate.
Therefore, the incorporation of the proposed drainage system that can adequately
accommodate water runoff considering freeboard is needed.
