Thottappally Spillway
Thottappally Spillway is Kuttanad's drain-way out to the Arabian Sea. The spillway splits Thottappally Lake with the fresh water part to the east and saline Thottappally river mouth to the west merging with the Arabian Sea. The spillway was constructed to spill excess water coming over the Upper Kuttanad and Lower Kuttanad regions through Manimala River, Achancovil River and Pamba River. It was designed to spill off 19,500 cubic meters of water per second, but after its construction it was found that it can only spill 600 cubic meters of water per second. The reasons for this reduced flow rate are strong sea breezes during rainy seasons resulting in a rise in sea level relative to the water level of Kuttanad Kuttanad is a river delta landscape region in the state of Kerala, India, known for its vast paddy fields and geographical peculiarities.

Kuttanad
Kuttanad is a river delta landscape region in the state of Kerala, India, known for its vast paddy fields and geographical peculiarities. It is in the Districts of Alappuzha, Kottayam and Pathanamthitta. The region has the lowest altitude in India, and is one of the few places in the world where farming is carried on around below sea level, using rice paddies largely located on reclaimed land amid the delta. Kuttanad is historically important in the ancient history of South India and is the major rice producer in the state. Farmers of Kuttanad are famous for Biosaline Farming. The United Nations Food and Agriculture Organization (FAO) has declared the Kuttanad Farming System as a Globally Important Agricultural Heritage Systems, Globally Important Agricultural Heritage System (GIAHS) in 2013. Four of Kerala's major rivers, the Pamba River, Pamba, Meenachil River, Meenachil, Achankovil and Manimala flow into the region. It is well known for its boat race in the Punnamada Backw ...

Manimala River
Manimala River, or Manimalayar, is a 92 km long river which flows through South and Central Kerala. The river used to be wrongly considered as a tributary of Pamba River before satellite maps became popular, but this was proved incorrect. Manimala does not flow into the Pamba, instead a distributary of the Pamba river flows into the Manimala river at Kallunkal, later branches out again from Manimala at Nedumpuram and flows through Niranam, Thalavady, Edathua, Changankary, Champakulam, Nedumudy, Chennamkary, and finally Kainakary and then empties into the Vembanad lake. This branch again links with the Manimala River at Chennankary in a short, but broad connection known as Munnattumukham. Manimala is a separate independent river for all geographical purposes. It has its origin on the uthavara Hills(1156 feet above main sea level) on the Western Ghats in Peermedu in Idukki district of Kerala, India. It has a length of about 90 km and flows through a catchment ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spillways
A spillway is a structure used to provide the controlled release of water downstream from a dam or levee, typically into the riverbed of the dammed river itself. In the United Kingdom, they may be known as overflow channels. Spillways ensure that water does not damage parts of the structure not designed to convey water. Spillways can include floodgates and fuse plugs to regulate water flow and reservoir level. Such features enable a spillway to regulate downstream flow—by releasing water in a controlled manner before the reservoir is full, operators can prevent an unacceptably large release later. Other uses of the term "spillway" include bypasses of dams and outlets of channels used during high water, and outlet channels carved through natural dams such as moraines. Water normally flows over a spillway only during flood periods, when the reservoir has reached its capacity and water continues entering faster than it can be released. In contrast, an intake tower is a structur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
