Impact of UK reservoirs on the surrounding environment

The paper tells that over the last 25 years, the “freeboard and spillway arrangements” for reservoirs in the UK have been based on the unit hydrograph rainfall-runoff and losses model. The model was used to obtain the design of the events of flood that would enable to determine whether the prevailing arrangements might convene the floods. The characteristics of drainage such as the area of the basin, the basin shape, the type of soil, use of the land, drainage density and drainage network topology, and the rainfall characteristics that include duration of the rainfall, its intensity, its distribution and direction are the different factors that might affect the shape of the hydrograph. The unit hydrograph model was established in the year 1975. However in the recent years, the model has been revitalized and hence replaced with the ReFH or Revitalized Flood Hydrograph Model that comprises three significant components – the loss, routine and baseflow models. The seasonality of the floods is also measured through this model such that factors of seasonal corrections are applied to the estimates of the flood designs and conditions with the purpose of meeting the floods. The Reservoirs Act 1975 led the responsibility of the law to protect the reservoirs in the UK. Approximately 25000 cu m of water is held by the UK reservoirs and the Act covers around 2500 reservoirs under its framework. England, Wales and Scotland are under the purview of this Act. ...
