According to the equations, a basin with high drainage density, the contribution of surface runoff to stream discharge will be high, while that from baseflow will be low. Conversely, a stream in a low drainage density system will have a larger contribution from baseflow and a smaller contribution from overland flow. [8] [9]
Drainage has undergone a large-scale environmental review in the recent past [when?] in the United Kingdom. Sustainable urban drainage systems (SUDS) are designed to encourage contractors to install drainage system that more closely mimic the natural flow of water in nature. Since 2010 local and neighbourhood planning in the UK is required by ...
Storm drain grate on a street in Warsaw, Poland Storm drain with its pipe visible beneath it due to construction work. A storm drain, storm sewer (United Kingdom, U.S. and Canada), highway drain, [1] surface water drain/sewer (United Kingdom), or stormwater drain (Australia and New Zealand) is infrastructure designed to drain excess rain and ground water from impervious surfaces such as paved ...
Such a drainage system is said to have a very fine drainage texture, [6] as measured by its drainage density. Drainage density is defined as the total length of drainage channels per unit area of land surface. Badlands have a very high drainage density of 48 to 464 kilometres per square kilometre (77 to 747 miles per square mile). [5] The ...
The 2020 Karachi floods (Urdu: سيلاب کراچی ) were the worst flooding Karachi had seen in almost a century, and killed at least 41 people. [1] [2] [3] The floods were caused by record monsoon rains from 24 to 27 August, [4] which were inadequately drained by poorly maintained drainage systems in the city.
The Red Lake sinkhole in Croatia. A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer. The term is sometimes used to refer to doline, enclosed depressions that are also known as shakeholes, and to openings where surface water enters into underground passages known as ponor, swallow hole or swallet.

A water supply network or water supply system is a system of engineered hydrologic and hydraulic components that provide water supply. A water supply system typically includes the following: A drainage basin (see water purification – sources of drinking water)
