Abstract

Sawahlunto Conservation Park is an area developed for plant protection and tourism activities. The Sawahlunto city was initially built to support coal mining activities, so the conservation park has several basins that can be used as flood parking ponds. These basins can be used to meet the needs of watering plants. The study is used to examine the water availability and flood analysis at the area to be built.  The conservation park is divided into three areas based on the four reservoirs location: the Kandih Park area, the northern and the southern part of the parking area. In this study, hydrologic and hydraulic analyses will be conducted. In the hydrological analysis, simulations of reservoir capacity are carried out to describe the amount of water that can be used every month. In the hydraulic analysis, SWMM program is used to model rainwater as surface runoff, estimate the planned channel dimensions, and reservoir flood volume. The reservoir simulation results show that the water needs for watering plants can be fully met. However, the available storage ponds have a much smaller volume than the rainfall volume, so the pond will run off throughout the year. The SWMM modeling results show that the channel dimensions from 0.2 m x 0.2 m to 0.5 m x 0.5 m, can drain flood discharge with a two-year return period, with a freeboard five-year return period. This study can be used as a guideline for developing conservation areas in reusing the potential of ex-mining land.

Abstract

Flooding is one of the most frequent natural disasters in Indonesia. Based on data, as of 2024, there have been 137 cases of flooding incidents. One of the causes of flooding, particularly in urban areas, is due to land use change. This study examines the impact of land use changes on runoff discharge in a Church area in the Bandung City. Additionally, this study investigates the effect of the development of this area on flood water levels in the Riung channel, which serves as an outlet channel. In this study, modeling is conducted using the SWMM model. The study utilizes data from the BMKG Bandung and GPM satellite rainfall data from 2001 to 2022 for rainfall analysis. The results indicate that in the study area, the duration of extreme rainfall producing maximum discharge is rainfall lasting for 7 hours. As a result of the church development, runoff discharge increases by 26.3 – 34.4% across various return periods. For time to peak, there is no significant change in conditions before and after the area is developed. This is due to area is relatively small, resulting in a relatively shorter concentration time. Based on the hydraulic analysis, the Riung channel is still able to accommodate additional runoff generated due to development, leaving a freeboard height of 4.5 cm for a 10-year return period. However, based on observations, special attention is needed regarding the issue of sedimentation and trash, which often causes backflow in several segments of the trenches.Keywords:runoff, land use change, urban drainage, SWMM, Bandung
