Abstract
Grouping both existing and newly planned reservoirs based on selected measurable characteristics allows to point out issues that are relevant to area management using experience obtained from the environment of other sites. Divisive hierarchical clustering has been deployed to find similarities between dam locations. The Nitra River Basin (located in Nitra District, Nitra Region in Slovakia) with its 54 reservoirs is the model area. Profiles for 11 potential new reservoirs have been developed. Partial river basins were identified for each of the existing and new reservoirs using a digital relief model. The area size, proportion of arable land, forestland and built-up area, degree of exposure to soil erosion and the volume of surface runoff have been used as parameters for comparisons. Six clusters have been identified containing similar existing as well as new locations, one of them being a special case.
Highlights
Water has been a basic requirement for humanity from the very beginning, and it used to be drawn from natural resources such as springs, rivers and lakes
A partial river basin and all input criteria were generated for each proposed final profile of a potential new reservoir, which were created for existing hydraulic structures and the river basins where they were situated
The river basins at the suggested locations suggested for the new and existing reservoirs were included in the cluster analysis
Summary
Water has been a basic requirement for humanity from the very beginning, and it used to be drawn from natural resources such as springs, rivers and lakes. It was when humans began to settle in larger numbers in urban regions that they found themselves in need of constructing adequate water reserves. Another reason why dams and reservoirs started to be built was to protect against erosion, flooding and fire, as well as for recreation and fishing, and rivers were where the construction of dams and hydraulic construction started, with channel reservoirs, irrigation canals and dam reservoirs necessary for supplying water or hydro-energy to cities and towns. Reservoirs provide protection, redevelopment, seepage, reserves, retention, implementation, accumulation and clearing. Just et al [2] commented that for a reservoir to fully function, it is crucial for it to meet these criteria of renewal and construction: (A)
