Gully erosion and associated risks in the Tutova basin - Moldavian Plateau

Stanga I. C.

Landform Analysis

Vol. 17

193-197

The present study approaches gully erosion in Tutova basin (south-central part of the Moldavian Plateau, Eastern Romania), mainly with the help of GIS and remote sensing by using the TNTmips 7.3. software. For this purpose a GIS was created, that integrates the Digital Elevation Model, geologic and morphometric maps, climatic and soil data, land use information and others. The assessment of risks associated to gullying has monitored several indicators, grouped as follows: gully-head advance and probability of affecting objectives located upstream; dynamics of gully banks; areal gully growth and loss of agricultural land; flooding and sedimentation of the land or social and economical objectives situated downstream the gully.
