Περίληψη

Η ενεργοποίηση των γραμμικών μορφών διάβρωσης στο νότιο τμήμα του Irkutsk προκλήθηκε από την κατασκευή και την εκμετάλλευση της τεχνητής λίμνης του Bratsk κατά τα μέσα του 10ου αιώνα. Στην εργασία αυτή περιγράφονται τα χαρακτηριστικά και η αλληλεπίδραση των φυσικών και τεχνητών παραγόντων που επηρεάζουν τη διαδικασία διάβρωσης. Η κατασκευή του φράγματος προκάλεσε νέους μηχανισμούς διάβρωσης, οι οποίοι δεν εμφανίζονται υπό φυσικές (αδιατάραχτες) συνθήκες, όπως είναι η καρστική, η αιολική και η διάβρωση λόγω τριβής. Μεγάλης κλίμακας τοπογραφικοί χάρτες χρησιμοποιούνται για την αξιολόγηση της χωρικής κατανομής της διάβρωσης στη ζώνη των ακτών; οι ενεργές διαδικασίες διάβρωσης παρατηρήθηκαν σε 16 τομείς της ζώνης των ακτών της τεχνητής λίμνης του Bratsk. Η έκταση της ακτής που επηρεάστηκε από τη διάβρωση είναι 332,9 χιλιάδες m2.
