The erosional, accumulative and postdepositional processes in flood plain after great flood of August 2002

The August flood of 2002 represented the largest Czech flood of the last 500 years and thus exceptional opportunity to study episodic processes. The documentation of morphological features and profiles had begun immediately after the flooding. Project is aimed for (1) the recognition of principal erosional and accumulative high flood processes; (2) the monitoring of flood plain development including destruction, bioturbation and incorporation of flood sediments into soil cover; (3) petrological, mineralogical and geochemical characteristics of flood sediments including leaching and mobility study of selected trace elements; (4) study of unusual phenomena related to water oversaturated sediments such as urban subsurface erosion, solifluction, trost cracking and trost diapirism. Besides an usual scientific output a popular monograph written for people living in inundated areas and focused on impact of future possible floods will be prepared.
