  3. Karst (Karst 🌍)

    Karst is a topography formed from the dissolution of soluble carbonate rocks such as limestone and dolomite. It is characterized by features like poljes above and drainage systems with sinkholes and caves underground. There is some evidence that karst may occur in more weathering-resistant rocks such as quartzite given the right conditions. Subterranean drainage...

  5. Estimating Increased Transient Water Storage With Increases In Beaver Dam Activity
    --
    doi.org/10.3390/w16111515 <-- shared paper
    --
    “Dam building by beaver (Castor spp.) slows water movement through montane valleys, increasing transient water storage and the diversity of residence times. In some cases, water storage created by beaver dam construction is correlated to changes in streamflow magnitude and timing. However, the total amount of additional surface and groundwater storage that beaver dams may create (and, thus, their maximum potential impact on streamflow) has not been contextualized in the water balance of larger river basins..."

  7. Polar desert (Deserts 🏜️)

    Polar deserts are the regions of Earth that fall under an ice cap climate. Despite rainfall totals low enough to normally classify as a desert, polar deserts are distinguished from true deserts by low annual temperatures and evapotranspiration. Most polar deserts are covered in ice sheets, ice fields, or ice caps, and they are also called white deserts. Polar deserts are one of two polar b...

  14. Landmass (Geology terminology ⛰️)

    A landmass, or land mass, is a large region or area of land that is in one piece and not noticeably broken up by oceans. The term is often used to refer to lands surrounded by an ocean or sea, such as a continent or a large island. In the field of geology, a landmass is a defined section of continental crust extending above sea level. Continents are often ...

  17. Flark (Pedology 🟤)

    A flark is a depression or hollow within a bog. Flarks typically occur as a series of parallel depressions, separated by intervening ridges known as strings.Early theories suggested that flarks were formed by frost heaving, but flarks have since been found in areas where frost heaving does not occur. Flarks are now thought to form when the peat that forms the base of the bog beco...

    Lay over some hydrology vectors, some of the underlying geology boundaries, etc - and the landforms become much easier to understand in terms of origin and development - the geomorphic/hydrologic/erosional/geologic/vegetative/etc equivalent of biology's “ontogeny recapitulates phylogeny”?

  19. What Is A Digital Elevation Model (DEM)?- A Practical Guide
    --
    equatorstudios.com/what-is-a-d <-- shared tutorial
    --
    “A Digital Elevation Model (DEM) is a digital cartographic dataset that represents a continuous topographic elevation surface through a series of cells. Each cell represents the elevation (Z) of a feature at its location (X and Y). Digital Elevation Models are a “bare earth” representation because they only contain information about the elevation of geological (ground) features, such as valleys, mountains, and landslides, to name a few. They do not include any elevation data concerning non-ground features, such as vegetation or buildings...”
