Deltares flume test measures how salt marshes blunt storm waves before dikes

Researchers built a large-scale physical model in Deltares' Delta Flume, transplanting 66 real salt marsh blocks onto a sand bed in front of a dike to study how marshes behave during extreme storms. The setup recreated field conditions, including a cliff edge at the seaward marsh boundary protected by a brushwood dam, and a sloped bare tidal flat to simulate natural wave approach before reaching the vegetated marsh.

Budget HDMI accessories help prevent signal loss over long distances

Extending an HDMI setup beyond typical cable lengths can cause attenuation, where the signal weakens and produces flickering, pixelation, or audio dropouts, especially past 25 feet. This becomes a common issue when trying to connect screens across multiple rooms, floors, or conference spaces. A range of inexpensive HDMI accessories, such as extenders and splitters, can help maintain signal quality without expensive rewiring.
