Coastal Screener


Assess design ideas for artificial beaches and beach nourishments

Screen beach designs quickly and easily with this user-friendly web-application

In the early planning stages of waterfront development or beach erosion mitigation projects, architects, planners and engineers are often tasked with quickly developing beach design or nourishment options to evaluate potential solutions.

With Coastal Screener, you can quickly and easily screen different beach designs both for erosion protection or to ensure sustainable new waterfront developments.


Beach designs for coastal protection against erosion and flooding or new waterfront developments are often developed using hand sketches on a map by architects or coastal planners. Coastal engineers then analyse available data, create back of the envelope calculations and rely on their intuition and understanding of coastal processes to evaluate these designs.

What if beach design schemes could instead be evaluated while they’re drawn on a map? Coastal Screener performs such an evaluation using input on the length of the structures, nourishment size as well as the desired position of the beach. Users can easily supply the necessary input on local wave conditions which drive the evaluation or it can be predicted based on wave data from DHI’s worldwide MetOcean On-Demand Data Portal with a single click.

The process is so simple, plus no special modelling expertise is required!

Evaluate beach designs for waterfront developments during the early planning stage

Input the stable orientation of the beach and you can evaluate beach designs for waterfront developments during the early brainstorming stage of a project

Quickly determine the viability of beach nourishments at your site

With a few clicks on a map, you can determine the necessary length and width of the required beach nourishment to quickly assess its viability for coastal protection

Enhance the creative process

Coastal planners and architects without modelling skills can take part in the creative process by making fast assessments of different beach designs to screen their feasibility

Get started right away

Even non-modelling experts can begin using Coastal Screener right away thanks to its straightforward and easy-to-use interface

Key application areas

Coastal Screener can quickly and easily screen:

  • Brainstorming ideas for beach designs in waterfront developments
  • Beach designs to mitigate coastal erosion and flooding
  • Beach nourishment designs to mitigate coastal erosion

Plus, you can use Coastal Screener to optimise the length and width of beach nourishments to meet targeted beach widths

Get started!

Coastal Screener is so easy to use. In just a few steps, you can screen the viability of a beach design or beach nourishment and share the results with others. Simply start by drawing the supporting structures and the position of the beach. The tool then shows the stable beach-position as well as the length of the structures and area of the new beach. You can then modify the length and position of the structures and immediately get the response of the coast.

It’s all about quality

At DHI, we have been solving complex challenges in offshore, coastal and marine water environments worldwide since 1964.

We answer the demands of today’s market as customers are asking for fast and simple worldwide digital access to actionable data and information.

Coastal Screener builds on the parabolic equation for crenulate bays by Dr. Hsu and the solution of the Pelnard Considere (one-line) equation. Combined with DHI’s advanced sediment transport calculations, this helpful tool then determines the future beach position.
