Flood resiliency
Climate change creates extreme weather patterns that can trigger intense rainfalls, cyclones and tsunamis. As a result, floods are becoming more frequent.
We are experts in structural and non-structural solutions to combat flood damage
Non-structural measures aimed at alleviating flood damages and building community disaster management system include land use management, land improvement and resettlement, flood forecasting, warning and evacuation systems as well as training and education of local engineers and residents.
DHI’s MIKE+ modelling platform provides advanced flood analysis and customisable systems for data management, real-time forecasting and control. In addition, their ClimADAPT application analyses future flood risks to support the design of cost-effective adaptation strategies.
Structural measures for flood management schemes include dams, retarding basins, river improvement, diversion floodways, channel widening and drainage improvement. Our multi-sector approach considers forest and cropland protection on upper basins to mitigate flood water on lower basins.
With the help of 2D flood models, flood prone areas can be identified and evaluated.
Using satellite images, a digital elevation model is created. This can be used to identify flow directions and to create a map of individual sub catchments within the watershed. The results can be combined with a 1D sewer simulation to gain a more comprehensive understanding of the flood situation.
