Assessment of factors and conditions influencing bank stability of future lakes

While including gradual long-term flooding of individual residual mining pits, the re-vitalization program of the Podkrusnohorska brown-coal basin area has to assure--beside general water quality standards--satisfactory stability level of future lake banks and their wider environment as required for safe usage of future water lakes. General assessment of factors and conditions influencing bank and/or slope stability of future lakes was realized within the frames of the Czech Republic Academy of Sciences grant project. The grant project solutions include a study of exogenous processes on localities where the mining has been terminated. Also, prognoses were developed on behaviour of future banks during flooding and subsequent operation of future lakes. The presented paper is focused on assessment of mayor factors that participate on initiation and intensity of the bank abrasion and sliding deformations. keywords: flooding of residual mining pits, dangerous geodynamic phenomena, stability of banks and slopes
