본 연구는 낙동강 진우도 전면의 해빈 포집시험구에서의 비사의 방향성을 조사하고 이를 바탕으로 해안표사 및 비사이동의 정량적․ 정성적 해석을 수행하고자 하였다. 춘계 약 1개월간 조사된 비사포집 결과를 바탕으로 해안사구 전면의 표사는 거동하며 서남(WS)방향에서 우 세하였다. 하지만 기상관측소 자료에 따른 풍향과 포집된 모래의 방향과는 다소 차이를 나타내었다.
A three year's field experiment was carried out on newly reclaimed tidal saline soils to evaluate the salt tolerance and growht characteristics, and their relationship to dry matter production and nutrient quality of main selected pasture species. Nine te
A two year's field experiment was conducted on newly reclaimed saline tidal lands to measure the effects of sand mulching on salinity of the soils and their relationship to crop performance. Hybrid sorghum cv. Pioneer 931 was grown under different mulchin
After identifying species by collecting the suspended and attached algae mat inhabiting in the slow sand-filter, Spirogyra sp., Mougeotia sp. and Closterium sp. were main green algae and Synedra sp. was diatom algae. Among them green algae Spirogyra sp. was dominant species. A result of observing the life mode of apple snail for a month after introducing into the slow sand-filter, apple snail eggs were discovered on the filter walls 2 weeks after introducing, 4 weeks later lots of eggs were observed all of the slow sand-filter walls, it means there is no problem for apple snail to live in the slow sand-filter. The observation result for algae removal potential by introduced apple snail after 2 months later, slow sand-filter where apple snail were introduced, a few algal mat were observed. On the other hand, no introduced apple snail into the slow sand-filter, lots of suspended algal mats were formed in the water and attached algal mats on the sand surface as well, these algal mat induced much of operating problems.
