Over most of geologic time, the long-term mean sea level has been higher than today. Only at the Permian-Triassic boundary ~250 million years ago was the long-term mean sea level lower than today. Long term changes in the mean sea level are the result of changes in the oceanic crust, with a downward trend expected to continue in the very long ...

GIS revolutionized curation, manipulation, and input for complex computational hydrologic models [2] [3] For surface water modeling, digital elevation model are often layered with hydrographic data in order to determine the boundaries of a watershed. [4] Understanding these boundaries is integral to understanding where precipitation runoff will ...
Rain falling over a drainage basin in Scotland.Understanding the cycling of water into, through, and out of catchments is a key element of hydrology. Hydrology (from Ancient Greek ὕδωρ (húdōr) 'water' and -λογία () '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 ...
In the rainy season, the Boteti discharges to the Makgadikgadi Pans, [1] bringing that area alive with seasonal activity and high biological productivity. [4] In the dry season, the Boteti is particularly important to provide wildlife an area to congregate, since most seasonal ponds and drainages are then devoid of water.
Hydrogeomorphology has been defined as “an interdisciplinary science that focuses on the interaction and linkage of hydrologic processes with landforms or earth materials and the interaction of geomorphic processes with surface and subsurface water in temporal and spatial dimensions.” [1] The term 'hydro-geomorphology’ designates the study of landforms caused by the action of water.

Hydrology (agriculture) Isotope hydrology is often used to understand sources and travel times in groundwater systems; Oscar Edward Meinzer is considered the "father of modern groundwater hydrology"; SahysMod is a spatial agro-hydro-salinity model with groundwater flow in a polygonal network;
