Integrated Coastal Zone Management (ICZM)

Integrated Coastal Zone Management (ICZM) is the integrated planning and management of coastal resources and environments. The objective of ICZM is to obtain co-ordinated management of the coastal zone as a whole in relation to local, regional, national and international goals. ICZM is based on the physical, environmental, socio-economic and political interconnections. It is a continuous and dynamic process, which can unite government and community, science and management, and sector and public interests in developing and implementing an integrated approach. ICZM implies the integration of environmental protection goals into economic and technical decision making processes with the objective of achieving sustainable development. IWM services would cover the following main themes:

• Resource assessment
• Coastal Flood Forecasting and management
• Cyclonic Surge Forecasting
• Impact assessment of development activities
• Cyclone risk and damage assessment

Coastal Hydraulics and Morphology (CHMor)

The IWM expertise in this discipline comprises development and application of advanced methods in response to challenges from a large number of coastal projects including advanced sand transport model capable of modelling the transport in any combination of waves and current, including conditions in the surf zone. Following outputs are generally envisaged from services in this discipline:

• Long shore sediment transport
• Shoreline management,
• Coastal impact,
• Sedimentation in harbours and navigation channels,
• Tidal inlet stabilisation
• Environmental Impact Assessment of Dredging and Reclamation

Port and Coastal Structure Management (PCSM)

The expertise in this discipline includes: definition of hydraulic design conditions, conceptual design of structures, optimisation of structures, interaction between structures and the ambient hydraulic regime, and environmental impact assessments. IWM would offer a complete range of services and tools required for the planning and design optimisation of

• Ports and marine terminals,
• Breakwaters,
• Marine and  hydraulic structures,
• Bridges and causeways, and
• Water intake and outfall structures.
• Impact analyses of wake wash from high-speed craft (HSC) and route optimisation

Estuary and Marine System Management (EMSM)

The Marine and Estuarine Systems expertise comprises of expert knowledge on natural aquatic systems, including water-sediment interactions that occur in mixed salt water and fresh water systems. The discipline of expertise deals with the following:

• 2D and 3D large-scale Hydrodynamics of (non) stratified systems, including tidal, density and wind driven currents
• Water quality processes
• Marine ecology
• Marine and estuarine management issues
• Water quality impacts studies
• Algae modelling
• Environmental management of lagoons and estuarine systems
• Risk assessment & Contingency planning
• Optimising monitoring strategy
• Oil-related pollution studies
• Assessment of tidal dynamics of Tidal Basin
• Drainage management of beels
• Optimisation of location of Tidal Basin
• Impact assessment on surface water salinity, groundwater and groundwater salinity
• Assessment of tidal prism in the river
• Relation between tidal prism and flow area and prediction of sustainability of river and tidal basin
• Assessment of sedimentation in the Tidal Basin
• Assessment of river sedimentation and scour

Offshore Structure and Pipelines (OfS&Pl)

This discipline encompasses the following areas of expertise:

• Wave climate statistics and predictions
• Risk assessments
• Layout of offshore terminals and moorings
• Deck elevation studies for platforms
• Provision of met-ocean data for design
• Scour and bottom protection modelling and design
• Pipeline behaviour and pipeline route advice
