THE APPLICATION OF THE TECHNICAL-ECONOMICAL INDEXES FOR THE EVALUATION OF THE PRIMARY LAND DRAINAGE NETWORK

Abstract

A set of technical-economical indexes was introduced in an earlier paper of this volume to evaluate the land drainage canal network of state property in Hungary. The catchments of theses canals form areal units, the so-called land drainage systems. This paper introduces the application of the method for the description and comparison of these areal units with the help of case studies. These case studies cover the fields of a national level grading, the sharing of reconstruction costs, the interest rates of multifunction canals as regional problems. A smaller scale grading is also given to determine an inlet restriction policy in case of a recipient with limited capacity.
