Risk of artificial lake 'Zavoj' to processes of erosion: Methodological, knowing and protecting aspect

Abstract

In this paper land erosion has been investigated from its temporal and spatial variability point of view. The aim of the application of contemporary soft wares and satellite observations was to create an adequate data base which allows faster and more adequate possibility for monitoring the intensity of erosive processes, as well as meaningful decision for application of different ways of anti erosive techniques of the most dangerous areas. Geomorphologic mapping of erosive processes using plane and satellite images has allowed rational planning of field observations and, at the other side very detailed establishing of the intensity of previous erosion. A new approach applied in this paper during data processing of all relevant parameters influencing erosion is based on using of software Geomedia 5.2 (Intergraph).

Rad tretira proces erozije zemljišta sa stanovišta njegove prostorno-vremenske varijabilnosti. Primena savremenih programskih paketa i satelitskih osmatranja ima za cilj formiranje adekvatne baze podataka, koja omogućava bržu i adekvatniju mogućnost praćenja stanja i intenziteta erozivnih procesa, a samim tim i svrsishodniju odluku o primeni različitih vidova anterozivnih mera zaštite najugroženijih prostora. Geomorfološko kartiranje erozivnih procesa putem avionskih i satelitskih snimaka omogućilo je, s jedne strane, racionalno planiranje terenskih opseravcija, a sa druge strane veoma detaljno utvrđivanje intenziteta erozije u prošlosti. Novi pristup primenjen u ovom radu prilikom obrade svih relevantnih parametara koji utiču na proces erozije, zasniva se na korišćenju programskog paketa Geomedia 5.2 (Intergraf).
