Abstract

Flooding is a natural event that often occurs in Indonesia. Magetan Regency has several areas drained by various rivers that have the potential to cause flooding problems in the event of high rainfall. Hydrological analysis is needed to determine the various rivers that are potentially unable to accommodate water capacity due to high rainfall, causing flooding problems. Thus, research aims to assess flood mitigation control based on a 25-year return period flood discharge (Q25) using the HSS Snyder method and HEC-HMS software. The flood inundation area due to river runoff is analysed using HEC-RAS 6.4.1 software using a 25-year return period discharge (Q25). This research uses retention basin as one of the efforts in flood mitigation, reducing the amount of flood inundation that occurs by using embankment planning. Retention basin is a water structure that functions to collect rainwater and water runoff to reduce flooding. Retention basin is one of the important steps in the flood inundation that occurred in Magetan Regency using HEC-RAS 6.4.1 software analysis was 3,75 km2. The largest flood inundation occurred in Kartoharjo District with an area 1,31 km2. The design of the Kartoharjo Retention Basin in Magetan Regency can reduce the flood inundation area by 22% to 2,94 km2.

Abstract

The meeting between the river and the sea is called the estuary which is a vital environment for the reproduction of marine life, especially fish. The estuary is preferred for industrial and commercial activities, including the construction of a lucrative port due to easy access to sea transport. However, estuaries face challenges such as sediment deposition that leads to shallow channels and river estuary closures. The mouth of the Luk Ulo River in Kebumen Regency, Indonesia, is particularly affected by sediment transport from the coast and changing the flow of the river to shrimp farming areas. To overcome this problem, the construction of a jetty is planned to stabilize the estuary. The study focused on the Luk Ulo River Estuary, utilizing wave, tidal, and bathymetric data to plan jetties effectively, emphasizing on the proper arrangement of tetrapods to prevent estuaries from becoming unstable. The research, which uses a quantitative descriptive approach, aims to determine the needs of tetrapods, porosity values, and the protective arrangement of jetties. The findings show that the Luk Ulo River estuary, which has a wave-dominated morphological characteristic, is susceptible to estuary closure due to sediment transport dynamics. Data analysis provides insights into tides, sediment transport, tetrapod placement and tetrapod needs that are highly beneficial for future projects, facilitating the design of effective jetty construction measures. This research contributes valuable information to coastal planning, especially in the regular arrangement of tetrapods and the need for tetrapods.
