Abstract

SYNTHESIS STUDIES TO IDENTIFY AND DETERMINE MUTUAL EFFECTS BETWEEN ENVIRONMENT COMPONENTS AND THE GENERAL BIOLOGICAL POPULATION OF THE CONSIDERED RIVER. THE GLOBAL COMPONENTS OF THE ECO-SYSTEM, I.E., WATER, SUBSTRATUM (BED-BANKS-AQUIFER) AND THE TROPHIC STRUCTURE ARE FUNCTIONALLY UNDISSOCIABLE, WITH THE RESULT THAT A CHANGE IN ANY COMPONENT AFFECTS THE OTHERS. THE GENERAL INVESTIGATION SCHEME IS SUGGESTED FOR THIS TYPE OF STUDY: A) GENERAL GEOGRAPHICAL STUDY OF THE CATCHMENT AREA| B) STUDY OF PHYSICAL, CHEMICAL AND BIOLOGICAL WATER QUALITY| C) TYPOLOGICAL STUDY OF STREAMS AND RIVERS, BASED ON MORPHODYNAMIC AND ICHTHYOLOGICAL DATA OR ANALYSIS OF THE BENTHIC INVERTEBRETE POPULATION| D) MORPHO-DYNAMIC AND BIOLOGICAL STUDY OF APPARENTLY MOST STABLE RIVER SECTIONS.
