The flushing flow method involves partially or completely emptying the reservoir behind a dam to erode the sediment stored on the bottom and transport it downstream. [7] [6] Flushing flows aim to restore natural water and sediment fluxes in the river downstream of the dam, however the flushing flow method is less costly compared to removing dams or constructing bypass tunnels.
Watershed management is the study of the relevant characteristics of a watershed aimed at the sustainable distribution of its resources and the process of creating and implementing plans, programs and projects to sustain and enhance watershed functions that affect the plant, animal, and human communities within the watershed boundary.

The aquatic ecosystem consists of a chain of organisms which are dependent on each other. When pollution causes harm to one organism only, this process can start a chain reaction and danger the entire aquatic habitat. When the proliferation of newly introduces nutrients evoke plant and algae growth, oxygen levels in the water decrease.
Water demand management came into vogue in the 1990s and 2000s at the same moment dams and similar supply augmentation schemes went out of fashion because they were increasingly seen as overly expensive, damaging to the environment (see Environmental impact of reservoirs), and socially unjust. Now, in the 2020s, it is accurate to say that ...
The self-styled WCD consisted of members of civil society, academia, the private sector, professional associations and one government representative, to measure the impacts and effectiveness of large dam development, including the effect on dam affected communities and project developers.
A detention dam is a dam built to catch surface runoff and stream water flow to regulate the water flow in areas below the dam. [1] Detention dams are commonly used to reduce the damage caused by flooding or to manage the flow rate through a channel. [2] Detention dams can also be constructed to replenish groundwater and trap sediment. [2]
This effectively diverted the Danube into Slovak territory and kept the development entirely within its borders. [7] This scheme dramatically reduced the amount of water flowing into Hungary and had a significant impact on that nation's water supply and environment. [7] As a result, the Hungarian government attempted to terminate the 1977 Treaty.
The New Centennial Water Source-Kaliwa Dam Project was a water project proposed by the Philippine Government in 2012, whose main component was the construction of the Kaliwa Low Dam in Tanay, Rizal, as well as a water supply tunnel, and the attendant infrastructure for these structures. [15]
