  2. Adaptive scalable texture compression - Wikipedia

    en.wikipedia.org/wiki/Adaptive_scalable_texture...

    Adaptive scalable texture compression (ASTC) is a lossy block-based texture compression algorithm developed by Jørn Nystad et al. of ARM Ltd. and AMD. [ 1 ] Full details of ASTC were first presented publicly at the High Performance Graphics 2012 conference, in a paper by Olson et al. entitled "Adaptive Scalable Texture Compression".

  3. Training (civil) - Wikipedia

    en.wikipedia.org/wiki/Training_(civil)

    Training or entrance training refers to coastal structures built to constrain a river discharging across a littoral coast so that it discharges only where desired. Untrained entrances on sandy coasts tend to move widely and violently to discharge into the ocean, often upsetting those enjoying land nearby.

  4. Bridge scour - Wikipedia

    en.wikipedia.org/wiki/Bridge_scour

    Most of the HEC-18 relationships are based on laboratory flume studies conducted with sand-sized sediments increased with factors of safety that are not easily recognizable or adjustable. [9] Sand and fine gravel are the most easily eroded bed materials, but streams frequently contain much more scour resistant materials such as compact till ...

    [8] [9] In April 2020, Nvidia advertised and shipped an improved version of DLSS named DLSS 2.0 with driver version 445.75. DLSS 2.0 was available for a few existing games including Control and Wolfenstein: Youngblood , and would later be added to many newly released games and game engines such as Unreal Engine and Unity .

  6. Armor (hydrology) - Wikipedia

    en.wikipedia.org/wiki/Armor_(hydrology)

    Armour of basalt blocks. In hydrology and geography, armor is the association of surface pebbles, rocks or boulders with stream beds or beaches.Most commonly hydrological armor occurs naturally; however, a man-made form is usually called riprap, when shorelines or stream banks are fortified for erosion protection with large boulders or sizable manufactured concrete objects.

  8. Meander cutoff - Wikipedia

    en.wikipedia.org/wiki/Meander_cutoff

    The term is equally used to describe the actual incidence of and potential tendency of a river to curve or meander over its length. [3] It is expressed as the ratio of the distance between two distant points in a river following the middle-of-the-river course of the river as compared with the straight distance between those points. [4]

  9. Rosgen Stream Classification - Wikipedia

    en.wikipedia.org/wiki/Rosgen_Stream_Classification

    The specific objectives of this stream classification system are as follows: 1) predict a rivers behavior from its appearance; 2) develop specific hydrologic and sediment relationships for a given stream type and its state; 3) provide mechanisms to extrapolate site-specific data to stream reaches having similar characteristics; and 4) provide a ...
