Abstract
The purpose of this study is to offer the basic data of the tidal river development program by grasping the diffusion between the high density-sea water and the low density-fresh water in the tidal river. The tidal range of Hyungsan river which flows at Youngil bay in Pohang was selected to analysis the phenomenon of density current. The results obtained are as follows ; The tide of Youngil bay was one time a day, 0.104m in high tide difference and 0.085m in mean tidy difference. The change of sea level by tide was negligible. The volume of reserved water by sea water was
평균조차(平均潮差)가 10cm내외(內外)인 포항(浦項) 영일만(迎日灣)으로 유입(流入)하는 형산강(兄山江)의 감조구간(感潮區間)을 채택(採擇)하여 유역내(流域內)의 부조(扶助) 수문기준점(水文基準點)에서 관측(觀測)한 자료(資料)와 하천유량(河川流量) 및 수질측정자료(水質測定資料) 등을 근거(根據)로 밀도유현상(密度流現象)을 분석(分析)한 결과(結果)를 요약(要約)하면 다음과 같다. 1. 영일만(迎日灣)의 조석현상(潮汐現象)은 1일(日)1회조(回潮)이며 대조차(大潮差) 0.104m, 소조차(小潮差) 0.066m, 평균조차(平均潮差) 0.085m로써 해면(海面)의 변동(變動)은 매우 작았다. 2. 감조구간내(感潮區間內)에는 해수(海水)의 영향(影響)으로 인(因)하여 약(約) 270만(萬)
