Hazard describes a situation that threatens life and properties.
Our work concentrates on natural hazards related to water including
floods, drought, tsunamis, storm surge, and cyclones. The hazards
are quantified using advanced modelling techniques together with
other assessment methods. Key issues when investigating e.g. flood
hazards include the delineation of the affected area and the
physical forces (flux) in the flooded area. Most often, such data
can only be provided by detailed numerical modelling of the
Our engineers and scientists have extensive experience using
proven approaches for investigating hazards. We routinely adopt a
multidisciplinary approach, integrating elements of mapping,
detailed terrain and site analysis including flood control
pathways, hydrologic analysis, hydraulic analysis, analysis of
retention/detention basin analysis, sediment transport, and
numerical simulations of flood propagation. We combine top level
expertise with a suite of state-of-the-art modelling tools and
analysis techniques, supplemented with focused field and site
surveys. Where required we include the FEMA methodology.
Our services include:
- Mapping using data ranging from public available SRTM and ASTER
over site investigation using accurate differential GPS.
- Analysis of geomorphology and historical flood analysis.
- Analysis of hydrology to assess drought and flood frequencies
- Simulation of flood propagation using most advanced modelling
- Conceptual development and design of potential flood hazard
- Hydraulic analysis.
- Sediment transport analysis.
- Scour analysis.
- Coordination with regulatory and flood control agencies.
Models and analysis techniques used:
- QuakeGen simulating earth surface movements based on Okadas
theory is used to estimate Tsunami sources.
- Unsteady flow is assessed using DHI MIKE 21 and MIKE FLOOD and
other tools in the MIKE by DHI model suite
- Sediment transport is assessed using the sediment transport and
morphology packages in DHI Software.
