River engineering, a branch of civil engineering, deals with the process of planned human intervention to improve and restore rivers for human and environmental needs. With modern technologies, data collection and modelling, navigation can be improved, dredging reduced and new habitats can be created.
Compendium of UK Statistics - Environment. This page lists the issues that the United Kingdom currently has that are related to the environment, such as pollution and contamination. In 2015, it was reported that for the past decade, the state of the environment in London had significantly deteriorated both in urban and rural areas.

The environmental impact of irrigation relates to the changes in quantity and quality of soil and water as a result of irrigation and the subsequent effects on natural and social conditions in river basins and downstream of an irrigation scheme.
The environmental impact of reservoirs comes under ever-increasing scrutiny as the global demand for water and energy increases and the number and size of reservoirs increases. Dams and reservoirs can be used to supply drinking water , generate hydroelectric power , increase the water supply for irrigation , provide recreational opportunities ...
The monitoring of the sediment yield of a river is important for ecologists to understand the health of its ecosystems, the rate of erosion of the river's environment, and the effects of human activity. [11] The Nile in Egypt is known for its fertile floodplains, which flood annually.
