Flood routing can be called a procedure for estimating / predicting the time and magnitude of the flood that will occur at a point based on known data. The purpose of this research is to know the flow of river flow in Krueng Meureubo watershed and to know characteristic of hydrograph in the upstream and downstream by using Muskingum method. The data used in this research is secondary data that is daily rainfall data and topographic map. The highest intensity of rainfall occurred in the 10th return period and the lowest occurred in the second return period. Coefficient value (k) 3400 s and value x 0.462. The results of this study indicate that the peak inflow discharge at 36,543 m3 / s, while the peak discharge outflow 35.934 m3 / s. The flow hydrograph with the Muskingum method shows that the difference in the initial value of the outflow input does not have a large effect on the resulting discharge, the resulting debit value is almost equal to the end of the hydrograph. From the results of this study is expected to be a reference for related parties to take preventive action or reduce the impact of flood disaster, and build an early warning system so that people can have a preparedness system.

This study aims to determine the number of biopori infiltration holes (LRB) that can increase water absorption into the soil, so as not to become a puddle. This happens because of land use changes that occurred in the campus field Teuku Umar University, including in the Engineering Faculty Teuku Umar University. Changes in land use and reduced open space on the UTU campus are expected to result in shrinking infiltrated rainwater and causing increased surface run-off. Increasing the flow of this surface can cause the existing drainage channel dimensions are not enough anymore so the water is abundant and there are floods inundation. Therefore, in order to avoid flooding this puddle, it is necessary to enlarge the infiltrated rain water, among others, with “Lubang Resapan Biopori” (LRB). The location of the LRB is done in front of the Faculty of Engineering building located on the UTU campus land, the LRB manufacture is done in 3 locations but one of the locations can not be used because of high runoff and puddles, therefore only 2 locations are made LRB manufacture, 3 cylindrical holes are made by digging in the soil using manual drill tool, 10 cm diameter drill bit and 80-100 cm long, and 100 cm LRB spacing, then organic waste. From the results of data analysis, the number of biopori infiltration holes recommended for the UTU Faculty of Engineering area requires as many as 68 LRB.
