Et vandfald er et sted i et vandløb, hvor vandet styrter lodret eller næsten lodret ned.
Også fordybning i en mark, hvor vandet samler sig.
Et endorheisk bassin, er en indsø, uden naturlige udløb, hvorfra vandet fordamper specielt i subtropiske og tropiske områder.
The World Waterfall Database
'The World Waterfall Database was established to provide a complete, accurate record of the waterfalls throughout the world, largely because such a record had not yet been established. Looking in any freely available Encyclopedia, entries for Waterfall usually yield a short list of well known or well publicized waterfalls but the lists are far from complete and usually rife with inaccuracies due to the data never having been field checked. Most people are unaware of these discrepancies because experts in the field have not readily been able to verify the data on such a wide basis'.

Aqueduct Country and River Basin Rankings: A Weighted Aggregation of Spatially Distinct Hydrological Indicators
by Francis Gassert, Paul Reig, Tianyi Luo and Andrew Maddocks - December 2013
'More and more countries around the world face high levels of water stress, but measuring and communicating that stress consistently is challenging. This paper ranks countries and river basins worldwide based on their exposure water-related risks. Specifically, it provides national and basin-level scores derived from more localized water-risk scores from the Aqueduct Water Risk Atlas. Rankings are available for 181 countries, the world’s 100-largest river basins by area, and the planet’s 100-most populous river basins for five different measures of water supply and demand.'

'The understanding of hydrogeology has ancient beginnings with the construction of qanats, which are slightly inclined tunnels dug into a hillside, to tap the groundwater contained in an aquifer, for use by settled populations in many parts of the Asian continent. The Greek and the Indian civilisations thrived on water drawn from wells, which are a specialised form of qanats in the sense that a well is a vertical shaft dug into an aquifer for the withdrawal of a reliable supply of water. The transition from this form of traditional and indigenous knowledge to quantitative hydrogeology is marked by the work of the French Engineer, Henry Darcy (1803–1858) who determined the mathematical law that governs the movement of groundwater through an aquifer. In less than a decade following Darcy’s statement the ability to predict the volume and rate of production of water from a well was widely understood among the earliest professional hydrogeologists.'
