摘　　要：敖江河口是一条径流量小,潮波变形剧烈,海域来沙丰富的强潮河口。由于上游建库,支流建闸,使下泄径流和河口进潮量减少,从而导致河口的淤积,其中以敖江港区淤积最为严重。本文依据天然实测资料,对河口和港区淤积原因作了分析论证。并利用一、二维耦合数学模型计算了丁坝整治工程和疏浚挖泥对改善港区的效用。Based on hydrological, sediment and topographial data obtained from field measurement and numerical model, this paper has analysed the reasons of silting in the navigation channel and alongside .quays in the port area.These reasons are: 1 ) river runoff decrease owing to builting reservoirs in the watershed. 2 ) flood tidal prism decrease owing to.builting barriers at the tributary;3) tidal wave drastic deformation in the esatuary.Finally, various measures for improving the depth alongside quays in the port area are put forward.
