DRAINAGE CHANNEL PLANNING STUDY TO OVERCOME FLOODING WATER ON THE MIDDLE ROAD OF BAKALAN VILLAGE, JOMBANG DISTRICT

Bakalan Village is one of the villages in the Sumobito sub-district, Jombang Regency. Which in the village road section if the rainy season often occurs puddles Rehabilitation or repair of drainage channels on the middle embong road of Bakalan Village is one of the Bakalan Village government projects that comes from village funds. To overcome puddles that often occur when the rainy season arrives, the level of puddles on the road can reach the knees of adults. The construction of this drainage channel with a total length of 243 m. The construction of this drainage channel aims to reduce waterlogging when it rains, so it is necessary to plan the right drainage system for flooded roads. From the existing conditions, it can be seen that the area that the middle embong road passes through is an area where during heavy rain there is often inundation due to poor drainage and lower road elevation than the surrounding drainage channels that can interfere with road users who pass through the road. In this final project, the things that are done are to conduct field surveys and literature studies, collect data (hierologic data, map data, and hydraulic data), analyze hydrology and hydraulics, plan culverts as drainage facilities, analyze elevations, then normalize rivers or village channels as drainage channels. The expected result of this planning is the drainage channel on the side of Embong Tengah Road which is expected to be able to overcome these problems besides that also to increase comfort in transportation and add aesthetic value to the road.
