Tree and woody vegetation penetrations of earthen dams and their appurtenances have been demonstrated to be causes of serious structural deterioration and distress that can result in failure of earthen dams. Damage to earthen dams resulting from plant and animal penetrations is a significant dam safety issue in the United States. The purpose of this technical manual for Dam Owners, is to advance awareness of the characteristics and seriousness of dam safety problems associated with tree and woody vegetation growth impacts on earthen dams, provide a higher level of understanding of dam safety issues by reviewing current damage control policies, provide state-of-practice guidance for remediation design considerations associated with damages associated with tree and woody vegetation growth on earthen dams, and to provide rationale and state-of-practice techniques and procedures for management of desirable and undesirable vegetation on earthen dams.
