This study describes the hydrogeological conditions of the coastal urban areas of Poti and Batumi, Georgia. A clear hydrogeological zonation can be mapped out. The hydrological influence of the rivers Rioni and Chorokhi on the environment of Poti and Batumi is evaluated. Infilling of the coastal zone with inert material has proven to be, and will remain, the most effective method of rehabilitation of the areas where coastal erosion is occurring.

The article illustrates the possibilities of enriching the expensive and precious metals using gleying microorganisms. Introducing our method will allow to make mining of the deposits waste-free or reduced wastes. Apart from this it will be possible to produce not only the main metals, but also the associated expensive components, including the gold and rare metals for technicaprogress. 

Natural and artificial slopes of various origins (mountain, road) are subject to intense soil erosion, leading to loss of land, as well as the spread of heavy metals and other harmful substances from open mine workings. This problem is especially important for Georgia, which for the most part is a mountainous country, where slopes of various geological composition and structure abound. Slope erosion is the cause of a significant violation of the ecological balance of the environment. In Georgia, conditions are easily created for sliding masses of various scales, which are a good object for scientific research and engineering solutions. The main advantages of the proposed method are: (1) the method is cheap, fast and easy to use; (2) the method is absolutely environmentally safe; (3) does not require additional materials or biotextiles, since the mixture consists of natural sorbents that have a high binding capacity; (4) the grass does not need to be sown into the soil, the grass seeds are mixed in the binding solution; (5) the method is applicable in a variety of geological conditions with different slope inclinations; (6) the result is achieved quickly, if the method is applied in late autumn, grass of controlled density will grow the following spring. As shown by the preliminary study, the composition of the binding solution must be adapted to specific climatic and hypsometric conditions.
