Optimizing Culvert Design for Creek Overflow Management: Determining the Optimal Structural Solution
Journal Title: Engineering and Technology Journal - Year 2025, Vol 10, Issue 04
Abstract
Flooding caused by creek overflow poses significant risks to communities, particularly in flood-prone areas with inadequate drainage infrastructure. This study examines the discharge capacity of Labni Creek in Brgy. Las Piñas, Peñaranda, Nueva Ecija, to identify appropriate engineering interventions for flood mitigation. Site inspections and hydraulic analysis revealed that the existing reinforced concrete pipe culvert is insufficient, with a discharge capacity of only 3.78 cubic meters per second, compared to the creek’s peak discharge of 89.8 cubic meters per second. The study also identified sediment accumulation, minimal vegetation, and the absence of flood control structures as key contributors to overflow. Using Manning’s and Rational Formulas, alternative structural solutions were evaluated, with a two-barrel box culvert emerging as the most effective design. This proposed structure meets AASHTO and DPWH standards, ensuring improved water flow management and reducing flood risks. The findings highlight the need for immediate intervention, including dredging, vegetation management, and upgraded culvert design, to enhance the creek’s resilience and safeguard surrounding communities from recurring flooding.
