TECHNICAL-ECONOMICAL BACKGROUNDS FOR THE EVALUATION OF THE PRIMARY LAND DRAINAGE NETWORK

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.
