Abstract
There is a dense land drainage canal network of state property in the lowland area of Hungary.
Based on the catchment area of these canals, a set of areal units, the so-called land drainage
systems are organised. The management of such a network always requires carefully made
decisions. This paper introduces a method for the description and comparison of these areal
units on a technical-economical basis. The method is based on well founded data giving
general information about the area concerned, and provides a clear set of indexes for the
evaluation. Though they are never the only parameters to be considered, the method is
suitable to support a wide range of decisions on national, regional and local level
