Flood inundation modelling


You have been commissioned by a Government Agency responsible for flood risk management to advise on the use of flood inundation models to support the various modelling requirements set out in the Table below. No. Application Predictions required 1 Large1 Scale Flood Risk Mapping i. inundation extent 2 Catchment Flood Management Plan ii. inundation extent iii. maximum depth 3 Flood Risk Assessment and detailed flood mapping i. inundation extent ii. maximum depth 4 Strategic Flood Risk Assessment i. inundation extent ii. maximum depth iii. maximum velocity 5 Flood Hazard Mapping i. inundation extent ii. maximum depth iii. maximum velocity 6 Contingency Planning for Real Time Flood Risk Management i. temporal variation in inundation extent ii. temporal variation in depth iii. temporal variation in velocity 7 Reservoir Inundation Mapping i. temporal variation in inundation extent ii. temporal variation in depth iii. temporal variation in velocity 1 Large scale can extend to catchments of 1000s km2 Undertake a review of the current literature on flood inundation modelling and author a report advising on the appropriate modelling techniques available for each modelling requirement. Your report should cover: one-dimensional and two-dimensional methods. Please note the purpose of the report and that the aim is to provide clear guidance to the Government Agency. Your report should contain be approximately 2000 words
