It should be treated estuary as an interface during the future research and we should strengthen the research on mechanism of estuarine interfacial self-adaptability.

在今后的河口研究中，应将河口作为界面，加深对河口界面的自适应性的认识，加强对河口界面自适应机理的研究。

So it is very impendence to study the project and operation rule to prevent or control flood of BuJi River.

在现有工程措施的条件下，研究河口水位的变化规律，特别是分析潮汐变化的一般规律，以及降雨径流对河口水位的影响，分析潮、洪共同作用下的河口水位变化关系，用来对布吉河流域的防洪调度进行指导，具有重要的意义。

Mouth bar can be divided into single and overriding types. In this paper, 18 conceptual models are set up according to different thicknesses, permeabilities, interbedded rhythms and injection-production conditions, and simulated by limiting water cut of 98%.

将河口坝划分为单一河口坝和叠置河口坝2种类型，建立了不同厚度、不同渗透率、不同夹层频率、不同注采条件等共计18个概念模型，并数值模拟至模型极限含水。

When sea level drops, forced by Kelioli, river mouth extends eastward and migrates southward, cutting down deeply. On the contrary, when sea level rises rapidly, river mouth jumps northward dramatically and moves westward, goes backward step by step. While sea level changes and river discharge is harmnize, as the geological depositional center is moving eastward and southward, driving by Keliolli and longshore drift, river mouth moves southward slowly, keeps relative stability, and forms the delta towards south slightly.

海面下降过程中，河流河口在科氏力作用下，南移东伸，下切迅速；反之，海面快速上升的过程中，河口则迅速北跳西移，逐步退缩；两者力量对比相当时，在沉降盆地沉降中心东移，并向南掀斜的背景下，在科氏力与沿岸流作用下，发育微微南偏的三角洲，河口缓慢南移，相对稳定。
