Surface runoff can cause erosion of the Earth's surface; eroded material may be deposited a considerable distance away. There are four main types of soil erosion by water: splash erosion, sheet erosion, rill erosion and gully erosion. Splash erosion is the result of mechanical collision of raindrops with the soil surface: soil particles which ...
The effects stem from the altered hydrological conditions caused by the installation and operation of the irrigation scheme. Amongst some of these problems is the depletion of underground aquifers through overdrafting. Soil can be over-irrigated due to poor distribution uniformity or management wastes water, chemicals, and may lead to water ...
This form of pollution can lead to many problems. One is the degradation of aquatic ecosystems. Another is spreading water-borne diseases when people use polluted water for drinking or irrigation. [3] Water pollution also reduces the ecosystem services such as drinking water provided by the water resource.
Nonpoint source water pollution may derive from many different sources with no specific solutions or changes to rectify the problem, making it difficult to regulate. Nonpoint source water pollution is difficult to control because it comes from the everyday activities of many different people, such as lawn fertilization , applying pesticides ...
Pollution prevention practices include low impact development (LID) or green infrastructure techniques - known as Sustainable Drainage Systems (SuDS) in the UK, and Water-Sensitive Urban Design (WSUD) in Australia and the Middle East - such as the installation of green roofs and improved chemical handling (e.g. management of motor fuels & oil ...
In the case of agriculture, one basis for NPS controls would be to tax farmers based on the amount of erosion they cause. However, measuring erosion and topsoil is expensive. Another way is to impose special purpose district property taxes on farmland that does not adopt BMPs or employ methods to reduce nonpoint source pollution. [68] Another ...
Sources of pollution Impact Darling River: New South Wales, Australia: Third-longest river in Australia, and the outback's most famous waterway. [204] Pesticide runoff [205] [206] Suffered from a severe cyanobacterial bloom that stretched the length of the river in 1992. [207] Also suffered from fish kills in 2019 and 2023.

Stream capture by headward erosion, leaving a wind gap. Stream capture, river capture, river piracy or stream piracy is a geomorphological phenomenon occurring when a stream or river drainage system or watershed is diverted from its own bed, and flows down to the bed of a neighbouring stream. This can happen for several reasons, including:
