Flood Alleviation Scheme in Melton Country Park
Flood Alleviation Scheme in Melton Country Park BY LROb Flood Alleviation Scheme in Melton Country Park Melton Country Park is an area of open space of approximately 137 acres. Major flooding of Scalford Brook in 1947, 1969, and 1975 meant industrial and residential properties were seriously affected and resulted in a detailed study investigating options to alleviate the problem. As a result, the dam was built in in 1989-1990, and was shortly opened after completion.

There are three lakes in total in the park; a weir controlled small upper lake, a lower lake which has its water level is controlled by a luice – allowing a certain volume of water flow down the Scalford Brook, and the main lake where the water level is controlled by the dam and a sluice (channel). The primary feature of the flood alleviation scheme in Melton Country Park is the Scalford Brook reservoir.
The reservoir was designed by Severn Trent Water Authority. The dam has been placed at 6m higher than original bank level, and has an embankment of 359m long. To achieve a suitable foundation, up to a 4m excavation was required at the centre of the valley. A network of footpaths was designed around the dam, and he newly created landscape was extensively remodelled and planted.
A brick chamber control acts as the outlet for the dam, inside which a throttle plate can be opened or closed to control the amount of water flooding through the dam into the stream and then downstream at the side of the dam. There is also a small area of the park which has been designed as a flood retention area to reduce any flooding which may happen. This area is maintained by Melton Borough Council, whereas the sewage pipes lying underneath are maintained by Severn Trent Water.
The mbankment is designed for overtopping in a 100 year flood, with the blocks above the downstream water level being filled with topsoil, and those below downstream water level were filled with gravel, this design was more economically sustainable When the Scalford Brook becomes flooded, water builds up behind the dam and floods the adjacent area; the water is then released at a controlled rate into the Scalford Brook. The Scalford Brook Dam was designed to protect the King Street and Thorpe End area of Melton Mowbray, especially the business and residential property.
