Notsukezaki Sand Spit is the longest sand spit in Japan and the wave and morphological characteristics vary along the spit. The main purpose of this study is to investigate the morphological changes of the sand spit for long-term and mid-term field observations and aerial photos. The natural and morphological characteristics are investigated based on the field observations and aerial photos for a long-term period (decades). The regional sediment budget is estimated using the shoreline changes and the result of wave hindcast simulation for five years. Finally, the cross-shore beach processes are examined using the numerical model, CSHORE.

The article describes the causes of occurrence and forms of geomechanical processes manifestation in surrounding coal-rock massif of mine workings supported by anchor support. Based on long-term field observations, six forms of typical deformations of the surrounding massif have been established. Design solutions to strengthen the anchor support or complete reinforcement of damaged sections of mine workings during geomechanical processes of local felling have been developed. They include: installation scheme, substantiation of parameters and list of used reinforcement elements; technology of work, a list of equipment used.
