A canal drop is built over the canal to lower the bed level in order to preserve the planned slope if there is a rise in the ground level to preserve the designed slope since there is a rise in the ground level. Canal collapse is planned to reduce the slope of the canal bed. If the angle of the canal bed is not lowered, the amplitude of the running water rises to an extra-ordinary level. If, on a sloppy site, the depth of the canal bed is not reduced, the building of the canal at a level higher than that of the ground becomes difficult. Construction of the fall of the canal would be used to produce steam. Some of the canal falls are rendered in the slope to lower the pace of the water falling in the canal. When the canal sinks sideways, the free-falling water destroys the bottom of the canal. Read more

Disadvantages of Canal Fall:

The irrigation channel with an embankment, namely the filling, does have the drawback of: Higher building as well as repair costs. Higher seal as well as percolation loss. The adjacent area is flooded owing to some potential break in the embankment. Difficulties of irrigation activities. As a result, the irrigation canal could not be placed in high banks. Falls are then applied at suitable areas to reduce the level of demand of the irrigation canal. The canal water instantly downstream of the collapsed structure contains enormous kinetic energy where, although not demolished can scour the canal bed but also banks downstream of the fall. It will also jeopardize the stability of the fall system. As a result, a fall in the canal is often followed by steps to disperse excess energy that, in effect, is a result of the construction of the fall. The location of the fall is largely determined by the topography of the region but the need to combine the fall with many other structural elements, including the bridge, the regulator, respectively. Throughout the context of main canals, the construction costs must be regarded. In addition, the relative economy of increasing the number of smaller falls (attaining balanced earthwork but ease of installation) compared to the smaller number of major falls (resulting in lower construction costs and improved power generation) has also been figured on. Throughout the situation of channels that irrigate the command area immediately, a reduction should be made until the channel bed is drained. The full supply level of the river should be held just below ground surface for a length of up to around 500 meters downstream of the fall, as the command area in this range can be irrigated by channels upstream of the fall.
