  • The composition and abundance of mesozooplankton were studied from the five stations on the Bulgap stream near Yeonggwang, Jeollanamdo, Korea. Mesozooplankton samples were collected bimonthly in April, July, August, October, and December 2006 and February 2007. Total 44 taxa of mesozooplankton occurred with the highest abundance (31$\sim$53,230 indiv. m$^{-3}$) in October, and the fewest (16$\sim$97 indiv. m$^{-3}$) in December. Diversity index is the highest in July (1.072) and the lowest in October (0.386). The two copepod species, Pseudodiaptomus inopinus and Macrocyclops albidus were dominant during the study periods. A brackishwater species, P. inopinus occurred in the Bulgap stream during from August 2006 to February 2007. This species was the most dominant species (53,010 indiv. m$^{-3}$) in the stations that usually have low salinities (0.1$\sim$14.0 psu). M. albidus was predominated during from April to August 2006 in the freshwater stations.

  • The coastal alluvial plain, sand dune, tidal nat might be the most prominent coastal landscape in western coast of Korea. The purpose of this paper is to examine the irrigation and drainage systems of the alluvial plain in the tidal coast. This study is concerned on the geomorphological and cultural landscapes of the alluvial plain in the western coast of the South Jeolla Province. The alluvial deposits have developed mainly by the actions of tidal currents, rather than transporting sediments by stream. The transformation of plain has been affected by human agency since 1920's. Dwellers have constructed the reservoir, banks, dammed pools, lock gates, and tide-dykes for the reclamation, irrigation, and drainage on the alluvial plain, coastal sanddune, and tidal flats.
