Flooding Risk

Evaluation of flood risk reduction at Tenggang River is needed to reduce the urban and coastal flood from high-intensity rainfall and sea level rise. This paper mainly discusses rainfall frequency analysis, simulation of hydraulic structure performed by HEC-RAS 5.0.3, and the proposed alternative flood mitigation for 25-year flood return period. Hydrology and hydraulic was analyzed to investigate the flooding risk. The result of simulation illustrated the improvement channel condition by normalization the riverbed and the increase of levee to solve flood inundation at Tenggang River using the designated flood return period (25 years of return period, Q25 = 119 m3/s). The result of simulation showed that the hydrologic-hydraulic modeling is acceptable compared to the report from the office of public work in Semarang City.

Over Time

Sandy foreshores play an important role in flood risk reduction in areas near seacoasts, estuaries and lakes. The morphodynamics of sandy foreshores or beaches in lakes, known as low-energy, non-tidal environments, have not been studied as extensively as open coasts. The goal of this research is to understand the relation between hydrodynamics and morphology on sandy lake beaches. At our four study sites, a sub aqueous horizontal platform evolved of which the elevation stabilizes over time. We conclude that the eventual elevation of these platforms is located at the depth of closure. Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/7TbmH3hXnDE

Abstract The planning of a flood control system in Indonesia is based on the planning criteria issued by the Ministry of Public Works. Flood control planning is based on flood discharge with a specific return period depending on the order of the river and the number of protected populations. Flood events in areas where the flood control system has been planned continue to occur almost every year, meaning that the probability of being exceeded is not as planned. This study is intended to evaluate the criteria for the magnitude of the designed flood discharge in flood control planning that considers the acceptable risk. Potential risks are evaluated against system reliability. The probability of failure of the flood control system occurs if the resistance is smaller than the load expressed as a performance function. By knowing the performance function associated with the level of flood risk, then the flood discharge can be selected with the appropriate return period according to the acceptable risk.
