Abstract
Mine drainage system is an effort to control the flow of water entering a work area so as not to interfere with mining activities. This research is intended as a form of implementation of the mine drainage system in the form of a discharge calculation by taking into account the condition of the watershed, then calculating the discharge plan for the return period to predict flood discharge at the research location. For rivers with high flow rates, it is planned to reduce the flood discharge in order to prevent the channel water level from exceeding its capacity. The research location is in Tlepok village, Karangsambung sub-district, Kebumen district, Central Java. In the study, the maximum river flow discharge was 1365.41 m3/s and the planned return period discharge was 520.46 m3/s up to 687.47 m3/s. Based on the calculation results, land conversion planning and river normalization planning were carried out to reduce the discharge in the watershed in Tlepok Village.
