The Engineer Research and Development Center (ERDC) Coastal and Hydraulics Laboratory (CHL) houses three state-of-the-art wave flumes that address research, design and development, and site-specific needs in coastal engineering. Projects range from fundamental research such as water wave physics, wave interaction with natural and nature-based features, and sediment transport to applications such as designing and testing military assets and coastal infrastructure to include armor stability, wave runup, reflection, transmission, forces, and overtopping. These flumes support the needs of government organizations and non-government organizations, including academia and the private sector.
An extensive variety of instrumentation complements the state-of-the-art capability of the flumes. The instrumentation includes capacitance wave gauges, acoustic Doppler velocimeters (ADVs), particle image velocimetry systems (PIV), underwater and surface motion tracking systems, terrestrial LiDAR, and mass property instruments. On-site shop capability includes custom model bathymetry; 5-axis CNC machining for plastics, wood, and metal; 3D printing; acrylic molding; and skilled trades like carpentry, welding, and plumbing.
Please contact us for more information on how the capabilities of the Hudson Integrated Coastal Engineering Research Facility (HICERF) can assist you in addressing and solving a variety of coastal science and engineering challenges.
The U.S. Army Corps of Engineers High Shear Stress flume (SEDflume) is designed for estimating erosion rates of fine-grained and mixed fine/coarse grained sediments and the variation of the erosion rate with depth below the sediment-water interface. This flume is based on a system originally designed by researchers at the University of California at Santa Barbara. The erosion data are used to predict stability for contaminated sediments, capping material, native sediment or dredged material
Flume no longer works with most tutorials because the twitter ingestion that flume uses (even the latest version) is using the old v1.1 streaming API, which is now deprecated, even with Elevated Access Deprecation announcement: Removing compliance messages from statuses/filter and retiring statuses/sample from the Twitter API v1.1 - #2
I first learnt of the Devils Hill Falls from a posting to Facebook with photos by the talented musician and avid outdoorsman Adam Young, last year if memory serves, and which I am now unable to locate (Facebook is impossibly poor at non-recent information retrieval); prior to that post, I had neither heard of them nor seen any references to them. Since I became aware of them, they have been on my hiking to-do list and were one of the primary motivations for swinging around to Louisbourg on the return trip from Meat Cove; I have also discovered other mentions of them, e.g., here, here, and here.
Photo #2 is much the same view as in photo #1, but taken a bit further back from the falls and showing more of the area above, but still too close to see the course of the brook there. The pool at the base of the falls can here be seen emptying via a flume in the lower left half of the photo. The lovely yellow leaves add their gold to the white of the falls, making for a lovely composition.
Photo #4 shows the lower portion of the flume, as it widens out at its bottom, forming a small cascade before continuing its flow at a much less rushed pace through the woods. It empties into the Catalone River about 700 m (0.4 mi) downstream of the falls.
Pastry Affair takes a rustic, honest approach to food. There may be a few rough edges, imprecise cuts, and crumbs sprinkled around the table, but that is what makes it feel like home. Designed for the home baker, Pastry Affair features recipes covering everything from cake and cookies to Sunday brunch.
Sometimes life saddles us with responsibilities we didn't ask for, never wanted, and couldn't anticipate. Big or small, these responsibilities become our own. Maybe they were never meant to be ours, but we can't help but make them into our own albatrosses to bear.
This morning while settling down on the couch to get some work done, I heard a chirp. At first, I wasn't sure exactly what I heard. It happened again. Chirp chirp. I looked towards the window to spot the bird, but the frame was empty.
The sound was coming from the fireplace. More specifically, it was echoing inside the flume. With my ear pressed up against the glass pane of the gas fireplace, I confirmed the worst. The little bird was trapped.
Strawberry Honey Oatmeal Bars are sweet and chewy. The bars bake up soft from the strawberry jam, yet hold together well making them extremely portable. I loved them hot from the oven, where the strawberry jam was thick and warm. However, they are just as good the second day, tasting better than the boxed cereal bars of a similar nature. I used this strawberry balsamic jam and they were fantastic.
In a large mixing bowl, cream together butter and sugar. Add the egg and honey, mixing until blended. Stir in the oats, flours, baking soda, and salt. Batter will be slightly sticky. Using floured hands, press 3/4 of the batter into the bottom of the prepared pan. Spread strawberry jam evenly over the top. Crumble the remaining 1/4 of the batter on top.
The flume nets were deployed with the purpose of capturing salt marsh nekton. Nekton species were identified to the lowest taxonomic level using species keys. The TIDE project aims to simulate eutrophication on a large scale by the addition of NO3- aiming to reach 70μM concentrations from May to September every year during the growing season. This fertilization of the marsh has been going on at Sweeney Creek since the 2004 growing season through 2016 and at Clubhead Creek in 2005 and from 2009 till 2016. Years 2017-2020 are enrichment recovery years.
All flume net collections occurred at night within 48 hrs of the monthly spring tide from June to September. Prior to sampling events the nets were lowered to ensure nekton could freely move in and out of the sampling area. At slack high tide teams quietly approached the nets and deployed them capturing any nekton inside the area of during high tide. As the tide fell nekton were funneled into the cod end where they were recovered at low tide. In the lab the nekton were identified to the lowest taxonomic level, measured to the nearest millimeter, and weighed to the nearest 0.01 grams. For fishes total length (TL) was measured from the tip of the snout to the end of the caudal fin. Shrimp TL was measured from the tip of the rostrum to the end of the tail. For crab species the carapace width was measured from its widest point.
From 2004-2006, as part of a series of experiments to understand the role of fish in food web controls, a barrier designed to prevent the movement of fish was installed in the right branch of SW and WE. The barrier was constructed of wood, PVC, and NITEX and entrenched into the creek bottom and side walls. Fish on the upstream side of the barricade were removed to create and artificially low density. Each year at the end of the season the fish blocks were removed and reinstalled in the spring of the next year. Denoted by LOW in the data.
I am the food safety and quality control coordinator in a potato pack house, we do not process any potatoes, only wash and package. I am wondering if there is anyone that can help me out as far as micro testing goes. Is it needed for potatoes? Also what kind of water testing should I look at? I'm thinking that the flume and wash water should at a minimum be tested if nothing else.
Thank you!
You have not to do micro testing on patatoes in my opinion. Because you are only washing and this means that you are cleaning only stone, dust..ect.. therefore micro activity will be on patatoes.. ( if you are not using any additives in water)..
But you should have to do micro testing on water that you use for washing and machines in process. ( you have to find water standard)..

you have to do first sorting the potatoes that may be contaminated cause cross contamination. u have to sorted out the good one and bad one . than off course u need some micro testing for water that u r going to wash the potatoes. and lastly the packaging must aseptic or vacuum that will help to retain the quality of potatoes for the longer period of time .
I grew up appreciating Adirondack water primarily in the form of its lakes and ponds. Our family began vacationing at Blue Mountain Lake nearly sixty years ago and by now I feel as though I know every island and every inch of its depths and shoreline.
