Measuring connectivity - A new approach for the geometrization of the landscape and for the enhancement of cost-effectiveness in landuse planning
Published December 27, 2009

The study aims to introduce a new method and approach for measuring the diversity of connectivity
with the help of the landscape geometrization, in order to create a new variable useful in landscape
metrics and to decrease the costs of landscape planning if its main goal is the enhancement of
connectivity. Using induction we identify t...he landscape elements with geometric elements,
calculating the theoretical maximum line, section, intersection point (node) number and compare
these values of the idealistic landscape to the values of the real landscape.

Morphometric changes of the River Bodrog from the late 18th century to 2006
Published December 27, 2009

The river regulations of the 19th century have affected each of our rivers to a different degree. In the
case of the River Bodrog it was stronger than the average. In our paper a section of the river between
Bodroghalász and Szegi was examined, the extent and intensity of river channel changes was
intended to be determined. The applie...d series of maps and aerial photos was georeferred and the river
channel was vectorized. The morphometric parameters of the channel were measured and the changes
were evaluated using the created database. From methodological aspect we concluded that the 9
variables can be grouped into 3 factors therefore most of the indexes can be substituted. We measured
the changes of length and lateral shift of the channel using GIS methods. Three development periods
were identified based on our results. In the first period the development of the river was characterized
by natural processes. Then, the development of the river altered owing to the antropogenic impacts. In
this transient phase the average shifting of the channel was 7.43 m/y. In the third term this value
reduces to 0.2 m/y as the river is getting to reach the equilibrium stage.
