Hydrology and Water Resources
Land reclamation is an improvement of land, which reduces the adverse effects of climate conditions and ensures the sustainable use of natural resources. Latvia is in humid soil area, which means that soils are formed under wet conditions. During the spring and autumn, these soils are wetted and unsuitable for land treatment. The installation of drainage systems shall ensure the reception of excess humidity and its removal from agricultural land, which makes it possible to process the land and to carry out economically justified agricultural activity. Of all pollution entering the Baltic Sea, agricultural activities represent 70% - 90% of nitrogen and 60% - 80% of phosphorus diffuse pollution load. To achieve the UN goals of sustainable development, there is need for innovative environmentally friendly land drainage system elements. The installation of reclamation systems to be performed shall include the cleaning and retrenching of ditches, the construction of a sedimentation basin, the conversion of part of the cannula system and the installation of the controlled drainage, the conversion of an existing ditch to a two-stage ditch, the installation of stone piles in an existing renewable ditch, the installation of a wood-chip bioreactor, alignment of excavated soil, restoration of existing culverts. The aim of this study is to develop the conceptual framework of environmentally friendly land drainage system elements technical solutions. The results of this research are developed calculation algorithms according to research and a probated to Latvia local land reclamation systems standards. The developed calculation algorithms can be used for environmentally friendly land drainage system elements technical design. The future research have to be focused on efficiency of environmentally friendly land drainage system elements.
