Research & Development

Research

For a company making scientific instruments, and offering expert consulting services, in-house fundamental research has a great value. It may lead to new or better solutions. Research leads to new questions, the questions lead to new instruments, and that can lead to new products or new ways of solving problems.

Lindorm's field is: Geomorphology, the geomorphologic processes (with special focus on water), the hazards these pose to society (natural hazards), and the impact society has on the geomorphology (environmental impact). Within the broad research field of geomorphology, Lindorm staff has published papers covering coastal processes, hydropower reservoir sedimentation and sediment flushing, statistical uncertainties in bathymetric measurements, sub-glacial lakes, geomythology, and on the abrupt climate change at the end of the ice age.

Development

In recent years we have focused the attention on the beach erosion problem in Florida, and the scarcity of material available for sand replenishment by dredging. Our objective is to develop a deeply submerged device for damping the waves offshore, to modify the wave climate and reduce erosion at hot spots on the shore. We have tested various designs in our own wave tank, and found a promising one which we call the Wave Engulfer™. A field prototype has been built for investigating the effects on the sediments, using SediMeters™ to monitor erosion and deposition.

We are also continuing the instrument development from Erlingsson Sub-Aquatic Surveys, utilizing the LogDator for various earth science applications. This includes both new versions of existing instruments, adapted for our field of use, and completely new instruments such as a self-contained SediSond™. If you need an instrument that has to do with sediments or geomorphological processes involving water, consider contacting Lindorm Inc.
