Nicole Sharp<p><strong>South Island Sediments</strong></p><p>In April and May late autumn storms ripped through Aotearoa New Zealand. This image shows the central portion of South Island, where coastal waters are unusually bright thanks to suspended sediment. We typically think of storm run-off as water, but these flows can carry lots of sediment as well. Here, the large amount of sediment is likely a combination of increased run-off from rivers and coastal sediment stirred up by faster river flows. (Image credit: W.

Nicole Sharp<p><strong>Dams Fill Reservoirs With Sediment</strong></p> <p><a class="" href="https://fyfluiddynamics.com/wp-content/uploads/temp_dam1.png" rel="nofollow noopener" target="_blank"></a></p> <p><a class="" href="https://fyfluiddynamics.com/wp-content/uploads/dam_temp2.png" rel="nofollow noopener" target="_blank"></a></p> <p><a class="" href="https://fyfluiddynamics.com/wp-content/uploads/dam_temp3.png" rel="nofollow noopener" target="_blank"></a></p> <p></p> <p>Dams are critical pieces of infrastructure, but, as Grady shows in this Practical Engineering video, they are destined to be temporary. The reason is that they naturally fill with sediment over time. Rivers carry a combination of water and sediment; the latter is critical to healthy shorelines and stable ecology. But while sediment gets carried along by a fast-flowing river, slower flow rates allow sediment to fall out of suspension, as demonstrated in Grady’s tabletop flume. As his river transitions to a deeper, slower-flowing reservoir, sand falls out of the flow, building up colorful strata. The sand and water even create dynamic feedback loops, as seen with the dunes that form in his timelapse and march toward the dam.</p><p>Any long-term plan for a dam has to deal with this inevitable build-up of sediment, and, unfortunately, it’s not a simple or cheap problem to address, as discussed in the video.

Nicole Sharp<p><strong>Growing Downstream</strong></p><p>This astronaut photo shows Madagascar’s largest estuary, as of 2024. On the right side, the Betsiboka River flows northwest (right to left, in the image). Less than 100 years ago, most of the estuary was navigable by ships, but now more than half of it is taken up by the river delta. Upstream on the river, extensive logging and expansions to farmland have caused severe soil erosion; the river carries that sediment downstream, dyeing the waters reddish-orange. As the river branches and the flow slows, that sediment falls out of suspension, building up islands and seeding new sand bars further downstream.</p> A difference of 40 years. A 2024 astronaut photo of the Betsiboka River delta compared with one from 1984 (inset). Several islands are labeled in both images. Notice how new islands have formed upstream of the ones seen in 1984. <p>In the image above, you can compare the 2024 delta to the way it looked in 1984. Letters A, B, C, and D mark the downstream-most islands from 1984. Today newer islands and sand bars sit even further downstream.

In Jan Erik Waider’s aerial film, we get a bird’s eye view of the result, watching pockets of sediment move downstream in pulsating waves and swirls. Along the coast, ocean waves pass over the internal ones, creating a mesmerizing crisscrossed wavescape. You can also compare Waider’s aerial footage to Roman De Giuli’s tabletop-scale films and be amazed by their similarities.

Nicole Sharp<p>Titan, one of Saturn’s moons, is the only other planetary body known to have liquid lakes, rivers, and seas at its surface. Whether those bodies — made up of hydrocarbons rather than water, like here on Earth — have waves is a matter of ongoing debate. What data we have from visiting spacecraft is inconclusive. So a group of researchers decided to look for <a href="https://doi.org/10.1126/sciadv.adn4192" rel="nofollow noopener" target="_blank">the effects of wave action</a> instead. </p><p>Beginning with a model of flooded areas similar to Titan’s, the team simulated a coastline’s erosion assuming three different situations: 1) no coastal erosion, 2) erosion from waves, and 3) uniform erosion through dissolution. Each set of conditions resulted in a very different final coastline. But, of the three, the wave-eroded coast was most similar to those seen on Titan. That’s a good indicator that, even if our spacecraft couldn’t see waves on Titan, they’re likely there.
