Hydrographic Coastal Monitoring

Maritime radar allows topographical survey of large and inaccessible intertidal areas
using a single sensor platform.



Conducting regular hydrographic surveys in complex and dynamic nearshore coastal areas is an incredibly difficult logistical challenge. Marlan have developed innovative remote sensing techniques in collaboration with the National Oceanography Centre. These use radar, video camera and other sensor technologies to derive topographic, bathymetric and hydrodynamic (wave & current) data in shallow coastal waters.

Unlike manual survey techniques, data are collected from fixed remote sensor platforms, enabling regular automated repeat-surveys with a high temporal resolution. Maritime radar allows coverage of large and inaccessible areas using a single sensor platform. Deployment of a Marlan survey system can increase your organisation’s situational awareness of challenging operational environments, providing better understanding of sediment migration, and trends of erosion and accretion. This information can inform better planning and decision making for maintenance operations, nearshore dredging and coastal defence construction.

features and benefits

  • Ideal for surveying extensive coastal areas, especially dynamic intertidal areas which are traditionally difficult to survey.
    • Facilitates proactive dredging operations and channel margin maintenance
    • Advance warning of sediment migration and erosion/accretion.
  • Excellent spatial and temporal resolution
    • Regular data products tell a story of coastal evolution and allow response to individual storm events to be monitored.
    • Aids diagnosis and understanding of processes acting on underperforming legacy infrastructure
  • Rapidly deployable containerised survey platform uses renewable power sources to be infrastructure independent, allowing remote areas to be surveyed.
  • Multiple sensor deployments allow observation of blind spots and longer coastlines
  • Flexible data provision schedule, tailors data delivery to your needs
