What are the causes and effects of water pollution?
Humans are the main cause of water pollution, which is triggered in many ways: by the dumping of industrial waste; due to temperature rise, that cause the alteration of water by reducing the oxygen in its composition; Or due to deforestation, which causes sediments and bacteria to appear under the soil and therefore …
What is water resource system?
A water resources system is the whole made from connected hydrologic, infrastructure, ecologic, and human processes that involve water. Ultimately, WRSA is used to improve water planning and management decisions and is best when closely coupled with practice [Loucks, 1995].
What is meant by water resource management?
Water Resources Management (WRM) is the process of planning, developing, and managing water resources, in terms of both water quantity and quality, across all water uses. It includes the institutions, infrastructure, incentives, and information systems that support and guide water management.

EFFECTS OF WATER POLLUTION
- Destruction of biodiversity. Water pollution depletes aquatic ecosystems and triggers unbridled proliferation of phytoplankton in lakes — eutrophication —.
- Contamination of the food chain.
- Lack of potable water.
- Infant mortality.
What is water pollution and its control?
Water pollution, to a larger extent, can be controlled by a variety of methods. Rather than releasing sewage waste into water bodies, it is better to treat them before discharge. If the secondary treatment of water has been carried out, then this can be reused in sanitary systems and agricultural fields.
