Before constructing the Cloaca Maxima, Priscus, and his son Tarquinius Superbus, worked to transform the land by the Roman forum from a swamp into a solid building ground, thus reclaiming the Velabrum. [5] [6] [7] In order to achieve this, they filled it up with 10-20,000 cubic meters of soil, gravel, and debris. [8] [9] [10]
The endorheic basin that feeds water into Üüreg Lake, Mongolia NASA photo of the endorheic Tarim Basin, China. An endorheic basin (/ ˌ ɛ n d oʊ ˈ r iː. ɪ k / EN-doh-REE-ik; also endoreic basin and endorreic basin) is a drainage basin that normally retains water and allows no outflow to other external bodies of water (e.g. rivers and oceans); instead, the water drainage flows into ...
Salt pan – Flat expanse of ground covered with salt and other minerals (salt flat) Sand boil, also known as sand volcano – Cone formed by the ejection of sand on a surface from a central point; Sandhill – Type of ecological community or xeric wildfire-maintained ecosystem; Sandur – Plain formed from glacier sediment transported by meltwater
The earliest type consisted of a "u" shaped trough onto which a flat lid was placed. Later the extruded clay pipe was developed. These are still used. These can be laid in an excavated trench, or a horizontal hole is formed in the ground using a mole plough and the pipes are forced in by means of a hand or mechanical press. By this means, heavy ...
Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not differ significantly at high tide and low tide, and around which a tidal crest circulates once per tidal period (approximately every 12 hours). The tidal amplitude increases, though not uniformly, with distance ...
a point where groundwater flows out of the ground, and is thus where the aquifer surface meets the ground surface: Strait: a narrow channel of water that connects two larger bodies of water, and thus lies between two land masses. Stream: a body of water with a detectable current, confined within a bed and banks. Stream pool

Water located beneath the ground surface An illustration showing groundwater in aquifers (in blue) (1, 5 and 6) below the water table (4), and three different wells (7, 8 and 9) dug to reach it. Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in ...
