Inland navigation

Nov 25, 2022MrKuchewarEncyclopedia

Inland navigation, inland barge transport or inland waterway transport (IWT) is a transport system allowing ships and barges to use inland waterways (such as canals, rivers and lakes). These waterways have inland ports, marinas, quays, and wharfs.

Ice sheet

Nov 25, 2022MrKuchewarEncyclopedia

In glaciology, an ice sheet, also known as a continental glacier, is a mass of glacial ice that covers surrounding terrain and is greater than 50,000 km2 (19,000 sq mi). The only current ice sheets are in Antarctica and Greenland; during the Last Glacial Period at Last Glacial Maximum, the Laurentide Ice Sheet covered much of North America, the Weichselian ice sheet covered Northern Europe and the Patagonian Ice Sheet covered southern South America. Ice sheets are bigger than ice shelves or alpine glaciers. Masses of

Hyporheic zone

Nov 25, 2022MrKuchewarEncyclopedia

The hyporheic zone is the region of sediment and porous space beneath and alongside a stream bed, where there is mixing of shallow groundwater and surface water. The flow dynamics and behavior in this zone (termed hyporheic flow or underflow) is recognized to be important for surface water/groundwater interactions, as well as fish spawning, among other processes. As an innovative urban water management practice, the hyporheic zone can be

Hydropsychidae

Nov 25, 2022MrKuchewarEncyclopedia

The Hydropsychidae are a family-level taxon consisting of net-spinning caddisflies. Hydropsychids are common among much of the world’s streams, and a few species occupy the shorelines of freshwater lakes. Larvae of the hydropsychids construct nets at the open ends of their dwellings which are responsible for their “net-spinning caddisfly” common name.

Hydropower

Nov 25, 2022MrKuchewarEncyclopedia

Hydropower (from Greek: ὕδωρ, “water”), also known as water power, is the use of falling or fast-running water to produce electricity or to power machines. This is achieved by converting the gravitational potential or kinetic energy of a water source to produce power. Hydropower is a method of sustainable energy production. Hydropower is now used principally for hydroelectric power generation, and is also applied as one half of an energy storage system known

Hydrology

Nov 25, 2022MrKuchewarEncyclopedia

Hydrology (from Ancient Greek ὕδωρ (húdōr) ‘water’, and -λογία (-logía) ‘study of’) is the scientific study of the movement, distribution, and management of water on Earth and other planets, including the water cycle, water resources, and environmental watershed sustainability. A practitioner of hydrology is called a hydrologist. Hydrologists are scientists studying earth or environmental science, civil or environmental engineering, and physical geography. Using various analytical methods and scientific techniques, they collect and analyze data

Hydraulic action

Nov 25, 2022MrKuchewarEncyclopedia

Hydraulic action, most generally, is the ability of moving water (flowing or waves) to dislodge and transport rock particles. This includes a number of specific erosional processes, including abrasion, at facilitated erosion, such as static erosion where water leaches salts and floats off organic material from unconsolidated sediments, and from chemical erosion more often called chemical weathering. It is a mechanical

Hudson Bay (Southern East Cree: ᐐᓂᐯᒄ, romanized: Wînipekw; Southern East Cree: ᐐᓂᐹᒄ, romanized: Wînipâkw; Inuktitut: ᑲᖏᖅᓱᐊᓗᒃ ᐃᓗᐊ, romanized: Kangiqsualuk ilua or Inuktitut: ᑕᓯᐅᔭᕐᔪᐊᖅ, romanized: Tasiujarjuaq; French: baie d’Hudson), sometimes called Hudson’s Bay (usually historically), is a large body of saltwater in northeastern Canada with a surface area of 1,230,000 km2 (470,000 sq mi). It is located north of Ontario, west of Quebec, northeast of Manitoba and southeast of Nunavut, but politically entirely part of Nunavut. Although not geographically apparent, it is for climatic reasons considered to

Horseshoe Bend (Arizona)

Nov 25, 2022MrKuchewarEncyclopedia

Horseshoe Bend is a horseshoe-shaped incised meander of the Colorado River located near the town of Page, Arizona, United States. It is also referred to as the “east rim of the Grand Canyon.” Horseshoe Bend is located 5 miles (8 km) downstream from the Glen Canyon Dam and Lake Powell within Glen Canyon National Recreation Area, about 4 miles (6 km) southwest of Page. It is accessible via hiking a

Glaciology

Nov 25, 2022MrKuchewarEncyclopedia

Glaciology (from Latin glacies ‘frost, ice’, and Ancient Greek λόγος (logos) ‘subject matter’; lit. ’study of ice’) is the scientific study of glaciers, or more generally ice and natural phenomena that involve ice. Glaciology is an interdisciplinary Earth science that integrates geophysics, geology, physical geography, geomorphology, climatology, meteorology, hydrology, biology, and ecology. The impact of glaciers on people includes the fields of human geography and anthropology. The discoveries of water ice on the Moon, Mars, Europa and Pluto add an extraterrestrial component to the field, which is referred
