The untraditional methodology of engineering geological application in the exploration of river Dams after a flood

Abstract

The submitted paper presents partial results of an engineering geological project of considering the right river levee of the Odra river in a section km 8,600 - 21,995 between Ostrava - Jih and Pudlov. Disastrous floods in July 1997 connected with local failures of the levee in examined area came out a question of necessary analysing those failures with a prognosis of possibility of their repetition in case of next loading of the levee with high water stands. The most critical for the filtration stability of the levee from a standpoint of their base conditions could be the places of transition of a levee fill over an original river bed and the dead channles, which can be often hardly defined in space by analysis of the graphic bases, which are lucidly elaborated in the relevant geographical information system. During next stages of the levee stability analysis is possible to pay particular attention to above mentioned critical sections well defined in space, if required.
