Hydraulic siphon
WebIn the present study, the optimum hydraulic and structural design of inverted siphon has been studied. Modified Hooke and Jeeves method considered in the present study and some modifications were doing. … WebSiphons are a way of passively moving water from areas of higher hydraulic head to areas of lower hydraulic head, through a pipe. Siphons can be used to lower the watertable under a seepage site if the flow from the siphon (or multiple siphons) is greater than the flow of groundwater to the site. Siphons can reduce surface salt levels at the seepage, …

WebA siphon allows you to drain water from a higher reservoir to a lower one, using a tube that goes up and over the edge of the higher reservoir, then down to the lower one (see Figure 1, below). You can initiate the siphon by applying negative pressure to the lower end of the tube (in other words, sucking on it like a straw).
