Shut-in – Type of rock formation found in Ozarks streams; Thalweg – Line of lowest elevation in a watercourse or valley; Towhead – Exposed landmass within a river; Shoal – Natural submerged sandbank that rises from a body of water to near the surface; Spring – A point at which water emenges from an aquifer to the surface
A body of water does not have to be still or contained; rivers, streams, canals, and other geographical features where water moves from one place to another are also considered bodies of water. [2] Most are naturally occurring geographical features, but some are artificial. There are types that can be either.
Block: Water descends from a relatively wide stream or river. [1] [2] Cascade: Water descends a series of rock steps. [1] [2] Segmented: Distinctly separate flows of water form as it descends. [1] Tiered: Water drops in a series of distinct steps or falls. [1] Punchbowl: Water descends in a constricted form and then spreads out in a wider pool. [1]
A rock formation is an isolated, scenic, or spectacular surface rock outcrop. Rock formations are usually the result of weathering and erosion sculpting the existing rock. The term rock formation can also refer to specific sedimentary strata or other rock unit in stratigraphic and petrologic studies.
Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type.Gross physical features or landforms include intuitive elements such as berms, cliffs, hills, mounds, peninsulas, ridges, rivers, valleys, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains ...
In the Middle Ages, water mills began to automate many aspects of manual labor, and spread rapidly. By 1300, there were at least 10,000 mills in England alone. A medieval watermill could do the work of 30–60 human workers. [19] Water mills were often used in conjunction with dams to focus and increase the speed of the water. [19]
A simplified definition of wetland is "an area of land that is usually saturated with water". [14] More precisely, wetlands are areas where "water covers the soil, or is present either at or near the surface of the soil all year or for varying periods of time during the year, including during the growing season". [15]
Most landslide lakes disappear in the first few months after formation, but a landslide dam can burst suddenly at a later stage and threaten the population downstream when the lake water drains out. In 1911, an earthquake triggered a landslide that blocked a deep valley in the Pamir Mountains region of Tajikistan , forming the Sarez Lake .
