Abstract:
PURPOSE: A fishway block and a downstream shoal type fishway therewith are provided to enable fishes to easily move from an upstream to a downstream. CONSTITUTION: A fishway block(100) comprises a block body(110), an elevated part(120), and side walls(140). The block body touches with the bottom surface of a river. The elevated part is protruded from the top of the block body and stops the flow of the river. The side walls are in contact with the block body and the side surfaces of the elevated part.

Abstract:
PURPOSE: A constructing method of the ground from landfills with dredged soil for tree planting is provided to reduce the stabilization period for soft ground formed with the dredged soil. CONSTITUTION: A constructing method of the ground from landfills with dredged soil for tree planting comprises the following steps: digging the dredged soil from a reclaimed ground surface layer into the predetermined depth; spread a drainage layer material selected from gravels, wood chips, or a first soil improver on the dug up space to form a drainage layer; preparing a vegetating soil composition by mixing the dredged soil with a second soil improver, and installing the composition on the drainage layer to form a vegetation layer; planting trees on the vegetation layer; and sowing seeds on the vegetation layer for fixing the surface of the ground.
Abstract:
PURPOSE: A method of fixing the surface of a slope using dredged soil is provided to stably fix the surface of a slope at a low cost by minimizing the use of external soil. CONSTITUTION: A method of fixing the surface of a slope using dredged soil is as follows. Dredged soil of 50-80volume% is mixed with mountain soil of 20-50volume% to form vegetation soil. A soil improvement material of 40-80kg per 1m^3 vegetation soil is mixed to manufacture soil composition for slope vegetation. The soil composition for slope vegetation is covered on the slope. The seed of plant is sown on the covered slope and a mat is covered.
Abstract:
A method for constructing a database for arranging stands with a GIS(Geographic Information System) and a stand arrangement method using the same are provided to automatically arrange the stands of a forest fire region by storing a plurality of factors for selecting a stand structure in a database, and modeling tree types and geography in 3D(Dimensional). Each layer is discriminated, and ground temperature before/after a forest fire of each region is detected and inputted. Land cover change before/after the forest fire is detected by using satellite image data. Change of vegetation index distribution property is detected. A geographic information database of each layer is constructed by using data obtained from previous steps. A 3D model database of each history of the tree kind is constructed, and a 3D landscape model database is constructed by using the 3D model database and the geographic information database. Weight is assigned to the layers related to stand arrangement of each region and is stored to the database.
