Introduction

“Wetland areas” as an independent category of natural water sites are very often omitted in the formulation of the subject of hydrological activities. These areas comprise lakes and marshes, water reservoirs of total depth below 6 m, coastal strips, and other sites of stagnant water or high humidity level.

Definition of wetland areas

These areas have characteristics, which have not been adequately studied by the contemporary environmental science since it would require the combined efforts of specialists from different research fields, including ecology, chemistry, hydrology, engineering sciences, economic sciences, etc. For this reason, the different specialists deal with different definitions, which is a natural outcome of the fields of their specific interests and research methodology.

Wetland areas are part of the natural environment characterized by permanent presence of water. The influence of the water cycle on the wetland areas is most often connected with changes...
