Chute spillway is an open channel like structure, which is constructed on steep slope of the gully face with a suitable inlet and outlet. It discharge flows from the reservoir to the downstream of river. Generally, this type of spillway is provided on earth or rockfill dam, to carry head drop of fairly large ranging from 5 to 6 m, so their main function is to control the gully head from its enlargement by waterfall erosion. The chute spillway is ideally suited with earthfill dams because of: (i): simplicity of their design andconstruction, (ii): their adaptability to all types of foundation ranging from solid rock to soft clay, (iii): overall economy usually obtained by the use of large amounts of spillway excavation for the construction of embankment. It handles the flow having supercritical velocity. Compared to drop structures, at such high drops and discharge rates, a chute spillway requires less construction material than an ordinary straight drop structure, and is, therefore, cheaper in cost. But it is more danger of undermining by rodents and threatening of foundation due to seepage in poorly drained locations.the chute structures do not provide any storage of water towards upstream side.Uses:Its uses are as follows:(i) For control of gully head.(ii) For conveying the runoff from upstream areas into the gully, very smoothly without erosion.(iii) It may be used as a structure for flood prevention, water conservation and collection of sediments.(iv) For controlling the gradient of natural or artificial channels.Adaptability:The chute spillways are suitable for following conditions:(i) For high overfalls, where a full flow structure is required.(ii) Where site conditions are not suitable for constructing check dams.(iii) This spillway can also be constructed in combination of check dams and other detention typestructures.Limitations:The various limitations of chute spillway are as under:(i) Ther is considerable danger of undermining due to rodents. For which, additional precautions are required to count.(ii) In poorly drained areas, there is problem of seepage.such areas are not suitable for chute spillways as seepage tends to weaken the foundation. In such areas if constructin of chu spillway is very essential and no other substitutes are available, then provisions to control the seepage problem are essentially made.(iii) For safety point of view, the construction site should be compacted very well or when earth filling is done that should also be compacted thoroughly. It is an additional work, which takes time and money both.
The most suitable climate for ducks is the woodlands mainly.

LDPE is the most cheaper type of polyethylene, suitable for simple objects.
This is because they are liquid. This helps them to be suitable to use in the vehicle as a type of fuel.
A 'pack-out' latrine is really the only suitable app here.
