Flood Hotspot Identification and Implications for Flood Preparedness

By • • Knowledge, Project, Public, Teaching • , , , • 7 minutes of reading

By Shahabuddin Amerudin Abstract This article presents a comprehensive analysis of flood hotspots, areas highly susceptible to recurrent or severe flooding. It delves into the considerations for identifying these hotspots, focusing on the role of timeframes and frequency thresholds. The article explores various methodologies, data sources, regional variations, and the implications for flood risk mitigation and management, with a specific focus on Malaysia’s flood hotspot scenario until September 2023. Introduction Floods are complex natural phenomena with the potential for catastrophic impacts on human settlements, infrastructure, and ecosystems. Effective flood risk assessment, disaster preparedness, and mitigation strategies necessitate a deep understanding […]

Oleh Shahabuddin Amerudin Pendahuluan Banjir adalah satu ancaman semulajadi yang melanda Malaysia dari semasa ke semasa, terutamanya semasa musim monsun timur laut. Kesan-kesan banjir boleh merosakkan harta benda, infrastruktur, dan mengancam keselamatan penduduk. Oleh itu, adalah penting untuk memahami hotspot banjir, iaitu kawasan-kawasan yang berisiko tinggi mengalami banjir secara berulang. Maklumat terkini yang diperoleh dari Jabatan Pengairan dan Saliran Malaysia (JPS Malaysia) mengenai jumlah hotspot banjir dan statistik mengikut negeri memberi gambaran mengenai kesiapsiagaan Malaysia dalam menghadapi ancaman banjir. I. Persebaran Hotspot Banjir di Malaysia Menurut data yang disediakan oleh JPS Malaysia sehingga September 2023, terdapat 5,648 lokasi hotspot banjir

Mapping Flood Risk Around the World: Which Countries and Populations are Most Vulnerable?

By • • Knowledge, Public, Research • , , , , • 3 minutes of reading

By Shahabuddin Amerudin The above figure shows the risk of flooding mapped around the world (Conte, 2022). The study uses data from Nature to map flood risks around the world and identifies countries and populations vulnerable to the risk of flooding (Rentschler et. al, 2022). The methodology includes both inland and coastal flooding risks. The Netherlands and Bangladesh have more than half of their population at risk due to flooding, followed by Vietnam, Egypt, and Myanmar. The Southeast Asia region makes up more than two-thirds of the global population exposed to flooding risk. China and India account for the highest

Flood Detention Basin: Techniques for Identifying Suitable Locations and Measuring Analysis Accuracy

By • • Knowledge, Project, Public, Research, Teaching • , , , , • 23 minutes of reading

A flood detention basin is a man-made structure designed to temporarily store stormwater runoff in order to reduce the risk of downstream flooding. The basin typically includes a depression or pond that can hold water during a storm, along with an outlet or spillway that slowly releases the water once the storm has passed. These basins are typically found in urban areas, where they can help to manage the increased volume of runoff caused by impervious surfaces such as roads, buildings, and parking lots. The basin is designed to hold a certain volume of water, known as the “detention volume,”

Types of Flood Models

By • • Knowledge, Project, Public, Research, Teaching • , • 3 minutes of reading

There are several types of flood models that can be used to simulate and predict the behavior of floods. These include: Hydrological models: These models simulate the movement of water through the hydrological cycle, including precipitation, evaporation, infiltration, and runoff. Hydrological models can be used to predict the amount of water that will flow into a river or stream, and to estimate the likelihood of flooding. They typically use mathematical equations to simulate the processes involved in the hydrological cycle, such as the movement of water through the soil, the discharge of water into rivers and streams, and the movement
