Flood

"An overflow of water onto lands that are used or usable by man and not normally covered by water. Floods have two essential characteristics: The inundation of land is temporary; and the land is adjacent to and inundated by overflow from a river, stream, lake, or ocean." (U.S. Geological Survey, 2019)

Floods in Sudan - Space-based Flood Monitoring to Support Disaster Risk Management

In 2019, floods caused 43.5% of all deaths due to natural disasters and thereby represent the deadliest type of disaster with an increasing number of events compared to previous years (CRED, 2019). Floods furthermore lead to the highest number of people affected compared to other disasters as they affect human activities and the economy (CRED, 2019; Elagib et al. 2019).

From Jakarta to Nusantara: Land subsidence and other pressing water challenges in a sinking mega city

Jakarta, “the sinking city”, is the current capital city of Indonesia. Located on the Java Sea, this coastal city is home to nearly 30 million people within the greater-Jakarta area. Jakarta has grappled with water management issues for decades, leading to several current day water-related crises. Access to a reliable, potable water supply is extremely limited as there is a significant disparity between those with piped water access and those without. Citizens without piped water access have consequently relied heavily on groundwater and have dug thousands of unregulated wells as a result. This has led to a second water crisis – the chronic overextraction of Jakarta’s underground aquifers. Land subsidence is of the utmost concern as this sinking city is placed at high flood risk from the surrounding ocean. Approximately 40% of Jakarta now lies below sea level as a result and predictive models suggest that the entire city will be underwater by 2050 (Gilmartin, 2019). Compounding these problems, the climate crisis has led to significant sea level rise as glaciers and ice caps continue to melt (Intergovernmental Panel on Climate Change, 2019; Lindsey, 2022). As the city of Jakarta continues to sink and sea levels rise, millions of citizens within Jakarta are at extremely high risk of flooding, particularly during monsoon season. Thousands of residents have already been forced to abandon their homes in search of improved conditions and higher ground (Garschagen et al., 2018).

Towards new applications of spaceborne technology on flood protection

Recently, in July 2021, destructive and deadly floods occurred in Western Europe. The estimated insured losses only in Germany could approach 5 billion Euros (AIR Worldwide, 2021). However, the total amount of the damage is currently not foreseeable due to the variety and complexity of the damage patterns and the unbelievable extent of the disaster. It seems the socio-economic losses will dramatically increase and break a new record in the insurance industry after evaluating the complete record of damages’ reports (see Figure 1).

UN SPIDER Recommended Practice: Mudslides and Associated Flood Detection Using Sentinel-1 Data

Overview:

Floods and landslides are the first and fourth most frequent disasters around the world (Petley, 2012). There are several examples of downstream flooding caused by massive mudslides where rapid mapping is an indispensable tool for supporting disaster management activities by civil protection authorities.

Recommended Practice: Flood Mapping and Damage Assessment using Sentinel-1 SAR data in Google Earth Engine

Floods, as natural disasters, are most commonly caused by storms and torrential rain or by overflowing lakes, rivers or oceans; this type of natural disaster is one of the most common and effects nearly every demographic and area on Earth. As they are wide-ranging disasters, floods leave disaster managers with a wide-range of concerns. The immediate concern during a disaster is that of human life and the infrastructure needed to offer emergency response through. Floods can wash away bridges and buildings, can destroy electricity systems and can even disconnect portions of cities or rural communities from the first responders who need to reach them. Long-term concerns caused by major floods focus on systemic damage; food is often the most serious concern as crops are destroyed and livestock drowns in major flood disasters. This Recommended Practice aims to create important disaster information for both the short- and long-term concerns of floods. The tool produces a flood extent map using Sentitnel-1 SAR images, as well as displays information about cropland and population centers affected in order to address the totality of major concerns that floods cause.

UN SPIDER Recommended Best Practice: Flood Hazard Assessment

Flood Hazard Assessment Model Validation

Overview:

Flood hazard assessments are critical to identifying areas at risk and taking relevant preparation and mitigation measures to address the hazard. Using the HEC-RAS 2D model for preparing flood hazard maps, this Recommended Practice explains how to identify flood-prone areas and exposed infrastructure. Through its focus on the prevention and mitigation stages of the disaster management cycle, it complements the Recommended Practice on Flood Mapping and Damage Assessment with Sentinel-2, also developed by SUPARCO.

UN SPIDER Recommended Practice: Use of Digital Elevation Data for Storm Surge Coastal Flood Modelling

Overview:

Storm surges and tidal waves are global phenomena that considerably affect human populations in coastal and island regions. According to the Guide to Storm Surge Forecasting published by the World Meteorological Organization in 2011, storm surges can be defined as “oscillations of the water level in a coastal or inland body of water in the time range of a few minutes to a few days, resulting from forcing from atmospheric weather systems. According to this definition, the so-called wind waves, which have durations on the order of several seconds, are excluded”.
