  • This study has been undertaken to research the characteristics of growth of Pinus thunbergii Parl., which were planted in Uljin-gun, Gyeongbuk, Coast Disaster Prevention Forest. The total amount of 3600 trees of 9 sand dune stabilizing hedges were monitored in the past 4 years. The relationship between tree growth with environmental factors such as wind speed, soil conditions and sand-accumulation fences has been compared and investigated. To increase the growth increment of coastal disaster prevention forests, the development of sand-accumulating fences is the most important factor in controlling wind speed effectively. The monitoring for the maximizing wind-break effect of the sand-accumulating fences should be investigated when building coastal disaster prevention forests.

  • The objective of this research lies in the effect of installation parameters influencing on the wind proof performance of the coastal forest for damage prevention. The dissipation ratio of incident wind power is developed as an assessment index to make a lumped parameter study possible. From the real field data of East, West, and South Sea bounded on the Korean peninsula, single and double storied forests were modeled in three-dimensional shape with computer aided design, and so was done the artificial structures such as wind break, sand accumulating fence, and sand dune, etc With a commercial code ANSYS-CFX, the computational result from the comparison of dissipation ratio between single and double storied forest shows the effect of composition, and also the installation effect is investigated for artificial structures with optimal dimension of distance.
