EVALUSAI SALURAN DRAINASE DI DESA PULO LOR KECAMATAN JOMBANG KABUPATEN JOMBANG PROVINSI JAWA TIMUR

Abstract

ABSTRACT

                Pulo Lor Village is one of the villages in Jombang District, East Java Province. Jombang District itself is a District with a fairly dense population, which results in a large amount of water running over during the rainy season. Pulo Lor Village is still not free from flooding and inundation problems like other large cities or districts. Pulo Lor Village is classified as not in good condition and is starting to experience a decline in the quality of drainage channels so that they are unable to accommodate runoff water which causes puddles and flooding. The method used is an alternative calculation in designing infiltration wells using concrete buis. The installation of concrete buoys is underground. In this study, concrete buisses are planned to be installed on several roads in Pulo Lor Village, Jombang District, Jombang Regency, as a solution to overcome flooding which is expected to be able to overcome excess design discharge so that there are no puddles on the roads. The results of this alternative flood management study suggest using infiltration wells to accommodate the planned flood discharge with a 10 year return period of 227,878 m3/second. Based on the results of the analysis, there are 7 channels that do not meet the design flood discharge capacity. For this reason, improvements have been made by planning infiltration wells as a flood prevention solution. The dimensions of the infiltration well are 1m in diameter, 0.5m in radius and 3m in depth. So we get a channel discharge that is able to meet the design flood discharge capacity in Pulo Loe Village 1,9158m³/det
