  1. Advancing Detailed Flood Hazard Identification in Alberta, Canada - Insights from Two Recent Flood Studies
    --
    doi.org/10.3390/w18131592 <-- shared paper
    --
    “The increasing frequency of floods and the severity of their consequences for public safety, infrastructure, and the economy demand improved methods for flood hazard identification. Flood studies that include flood hazard mapping are critical tools for informing emergency response and flood recovery, as well as for land use and mitigation planning. The methodology for such flood studies has evolved, and access to more powerful computational resources and high-resolution base data has contributed to the increased use of two-dimensional hydraulic modelling, where one-dimensional modelling previously was the default. However, local-scale flood studies face real-world constraints, including sparse data, challenging hydrologic conditions, and budget limitations, which can hinder the application of advanced techniques. This study addresses these challenges through innovative, practice-driven solutions in two case studies in Alberta, Canada: a small, partly channelised prairie stream network (Wolf Creek, Lacombe) and a laterally dynamic river on a distributary delta (Swan River, Kinuso). Three core components of flood hazard studies are described: field survey data collection, regional hydrology assessment, and hydraulic modelling. Key findings include demonstrating that LiDAR-derived terrain models alone cannot capture channel conveyance, the importance of low-flow calibration in the absence of high-water marks, the selection of a modelling methodology based on bathymetric and topographic features within a study area, and the development of inflow hydrographs for unsteady-state simulation in flat floodplains…”

    “Rivers are critical resources that affect everything from watersheds to agriculture to energy. But rivers, in turn, have been impacted by humans, often in the form of hydraulic infrastructure such as dams and wells.
    A new [Cornell] project… will create a global record that shows how river systems around the world have changed under human influence over the last 75 years…”

  8. Hydraulic jump in the atmosphere over the eastern half of New Mexico.

    This animated loop from visible light weather satellite images this morning shows a middle layer of clouds over the eastern half of New Mexico. The location of the cloud is stationary, but the winds are howling up there.

    This cloud shows the presence of a hydraulic jump in the atmosphere. The trigger point roughly coincides with the 'central spine' of high terrain in New Mexico that runs north/south.

    en.wikipedia.org/wiki/Hydrauli

    Glider pilots can find lift a short distance upwind of the start of the hydraulic jump cloud. (The challenge is finding other lift to get up there.)

    [Edit/add: a cool photo before dawn of part of this cloud formation:

  10. Finally had a chance to work on this out that I got..atleast a year ago. Was a heckin lot of fun, can't wait to out the other one together and start putting decals on them. Anyone up for a boxin' match? Dibs on the Roo.

  11. ✅ Elevated #CO2 concentration increases #maize growth under #water deficit or soil #salinity

    ❌ ...but with a higher risk of #hydraulic failure and mortality

  12. Oh, they come in sizes? How do I know what size/rate this one is? There are some numbers on it, but they don't obviously match any volume per unit time measurements.

  13. #Treeline #trees are often prone to #hydraulic limitation. Growth limitation from hydraulic failure at higher altitude trees might be reduced when #climate is #warming, and the growing environment at timberlines might become improved. This means that from a hydraulic perspective the is no limitations for treelines to move upwards, and trees can thus increase their #distribution in that direction: besjournals.onlinelibrary.wile

  14. YouTube videos make bleeding #hydraulic #brakes look simple. Everything is now covered in mineral oil! Glad it cleans up easily. #BikeTooter #mastobikes #cargobike #discbrakes #bicycle

  15. @BrianPierce @DrEvanGowan I’m aware of #glacial #kettle #ponds on #CapeCod, but not in #tidal #wetland settings like this. I am wondering whether a kettle could persist for ~ 12 ka as meters of #sediment and #peat accumulate in the #marsh as #sealevelrise floods the #estuary during the #Holocene. @Anthro’s suggestion of #hydraulic scouring, or something similar, may be the explanation. Much to learn! Thanks for your post. #Massachusetts #geology #Boston #geoscience
