Development of a Program for Analyzing Road Culvert Design in Highway Area

Abstract

Climate change and land use alterations significantly impact the efficiency of road culvert drainage systems, as increased water level and runoff often exceeds the design capacities defined by past standards. This study aims to develop computer programs an analytical and design program for road culverts using MS Excel, enabling accurate and precise calculations that accommodate climate changes, road widening, and surrounding land use modifications. The developed program enhances usability and ensures suitability for current conditions. The study involves data collection and performance verification of culvert designs based on the design standards of the Department of Highways. The findings demonstrate that the developed program can accurately determine the size and quantity of road culverts and according to the standards of the Department of Highways. Additionally, the improved design enhances drainage performance compared to conventional methods. This research provides a crucial framework for optimizing road culvert designs to adapt to future environmental changes, mitigating of flood impact  and promoting sustainable environmental management in the study area.
