Quantification of Loss of Access to Critical Services during Floods in Greater Jakarta: Integrating Social, Geospatial, and Network Perspectives

Remote Sensing, Journal Year: 2023, Volume and Issue: 15(21), P. 5250 - 5250

Published: Nov. 5, 2023

This work presents a framework for assessing the socio-physical disruption of critical infrastructure accessibility using example Greater Jakarta, metropolitan area Indonesian city. The first pillar is damage quantification based on real flood event in 2020. Within this pillar, system network statistics before and shortly after were compared. results showed that impeded access to facilities, distorted transport connectivity, increased vulnerability. Poverty was found be negatively associated with surface elevation, suggesting urbanization flood-prone areas has occurred. second simulation. Our simulations identified locations clusters are more vulnerable loss during floods, entire can applied other cities urban globally adapted account different disasters physically affect infrastructure. demonstrated feasibility vulnerability assessment relying solely open publicly available data tools. framework, which uses satellite occurrence floods made by space agencies timely manner, will allow rapid ex post investigation consequences disasters. It save resources, as analysis performed single person, opposed expensive time-consuming ground surveys. Ex ante help communities, planners, emergency personnel better prepare future shocks.

Risk Assessment of Rainstorm Disaster Based on Scenario Construction

Published: Jan. 1, 2024

China, a country prone to frequent rainstorms, faces the pervasive threat of rainstorm disasters across most its regions. This paper aims enhance our scientific understanding risks and impacts associated with sudden, extremely heavy disasters. The focus research is on scenario construction, incorporating consideration disaster chains utilizing various technologies conduct comprehensive assessment risks. Within realm risk assessment, this study places particular emphasis rainstorms. "Scenario-Task-Capability" methodology employed analyze characteristics these scenarios. In "capability" analysis, chain established, an evolution network model for events formulated. Taking into account nature sources, regional tolerance capacity, control abilities, among other factors, time series-based developed. validated using case in southwest China. findings reveal that area are predominantly medium high levels, constituting 27.968% 28.101% total area, respectively. These concentrated middle-west northeast regions area. Low-risk areas cover 21.381% primarily located central part dispersed direction. An high-risk encompassing 22.549% scattered northern

Hydro-Morphometric Analysis for Flood Potential Assessment in Swarna Watershed, Karnataka, India- Implication on Coastal Water Conservation and Protection

Research Square (Research Square), Journal Year: 2024, Volume and Issue: unknown

Published: May 31, 2024

A thorough understanding of mountain hydrological processes and a careful assessment the characteristics coastal watersheds are essential for managing floods effectively. This work uses RS GIS approaches to analyze hydro-morphometric aspects in Swarna watershed. Gaining important insights into flood zone through integration innovative techniques is addressing challenges posed by climate change management water resources. Finding highest priority sub-watersheds based on morphometric traits, potential indicators, land use/land cover (LULC) analysis main goal current study. all-inclusive approach prioritizes classifies detected considering thirteen different characteristics, such as linear, areal, relief measurements. Further, improve ranking process, study also incorporates nine LULC features two indicators potential. Following these extensive evaluations, three groupings significance—high, moderate, low—have been established sub-watersheds. Within high-priority sub-watersheds, SW5 SW6 designated low risk high groundwater recharge, while SW1 SW2 high-risk zones recharge areas. These developments present significant opportunities decision-makers, providing them with strong foundation formulating implementing efficient watershed plans. Interdisciplinary play critical role properly integrating surface harvesting Techniques including artificial structures, check dams, rainwater systems merged smoothly conventional protection strategies. The long-term welfare communities secured strategies, which not only reduce flooding but supply ecosystem sustainability.

Urban waterlogging risk assessment and drainage parameters design of Xicen Science and Technology Innovation Center based on satellite remote sensing data

Published: June 21, 2024

Under global warming, the increase in extreme rainfall events has led to a significant rise frequency of urban waterlogging disasters, and major cities are facing severe risks waterlogging. In this paper, revised "annual maximum method" was utilized develop intensity formula suitable for Xicen Science Technology Innovation Center (XICEN). Based on satellite remote sensing data SCS-CN model, we evaluated under five scenarios with return periods 5a, 10a, 20a, 50a, 100a through inversion method critical rainfall. The results indicate that when hourly exceeds 50mm, may affect entire study area. Furthermore, as period extends, risk also increases. scenario 5a period, is mainly categorized mid-low or low risk; however, XICEN mid-high levels. These findings can serve references disaster response future construction planning.
