Integrated urban flood risk management: Learning from the Japanese experience

In the summer of 1742, two typhoons swept across Japan in quick succession, bringing water_quality_mason_jartorrents of heavy rain and flooding major rivers. Records from a young monk who witnessed the floods describe a muddy wave destroying levees and sweeping through villages. As levees and rivers collapsed, floodwaters rose in Edo, Japan’s largest c

nly days later, and

resulting in fatalities of a reported 6,000 in the city.

eC2: Understanding urban flood risk in Jujuy, Argentina

Deadline: 31-Oct-2018 at 11:59:59 PM (Eastern Time – Washington D.C.)

The World Bank is seeking consultant services to analyze urban flood risk in the city ofpexels-photo-831890.jpeg San Salvador de Jujuy, Argentina, as part of the World Bank’s City Resilience Program. Specifically, the consultancy will focus in the Chijra River. The expected tasks include:
1. Diagnosis of current situation including compiling, preparing, complementing and / or updating existing information.
2. Develop a Digital Terrain Model for the whole basin using the existing information.
3. Analysis of hydrological aspects; mainly the review of the studies available within the basin and close to it, considering the historical values and the climatic tendencies indicated in the recent history.
4. Construction of a 1D hydrodynamic model for the area based on the MDT.
5. Evaluate the possibility of calibration of the models with background information.
6. Prepare the base cartography of the area based on the available information.
7. Define the design events for the exploitation of the hydrodynamic model.
8. Draw the flood lines for the different scenarios.
9. Analyze sediment transport at basin level.
10. Identify erosion / sedimentation zones.
11. Identify existing infrastructures that affect natural runoff.
12. Identify population and infrastructure exposed to risk.
13. Identify mitigation works for both floods and erosion / sedimentation phenomena.

The assignment and all deliverables will be in Spanish.

eC2: Strengthening Natural Hazard Resilience in Yemen’s Major Cities

Deadline: 14-Aug-2018 at 11:59:59 PM (Eastern Time – Washington D.C.)

The World Bank will carry out a multi-hazard assessment in Sanaa, Aden and 2286002741_fdde7127e5_bHodeidah. These cities are exposed to hazards such as coastal and urban floods, seismic activity, tsunamis, volcanoes and water scarcity.
The consultancy will develop hazard maps, assessing individual hazards and their interdependence. The assessment will provide spatial insight into the hazards footprints in the form of fully licensed, GIS compatible datasets. It will gauge the exposure of each of the cities to hazard risks, considering their location, attributes, and when possible vulnerabilities and the value of their assets.
