然后以实测资料为基础分析研究了三门峡建库前后潼关高程的变化规律以及渭河下游河道的冲淤演变规律，分析研究表明：建库前渭河下游主槽处于动态冲淤平衡状态，滩地处于微淤状态；建库后，渭河下游河道发生严重淤积主要是由于潼关高程的抬升造成的；潼关高程的抬升主要是由于三门峡水库的不合理运用造成的，近期不利的水沙条件加剧了潼关河床的抬升速度和渭河下游的淤积。 | | 4. | The optimum design mathematical models of both kind channels are developed in accordance with the theory of minimum rate of energy dissipation . the rate of energy dissipation of flow is used as the objective function , and the condition of both non - eroding and non - silting , or the condition of equilibrium of eroding and silting is the constraint

分析结果表明： 20世纪60年代下荆江裁弯后，三口（松滋口、太平口、藕池口）分流分沙减少，下荆江径流量和输沙量相应增加，洞庭湖泥沙淤积减少； 80年代中期以后，长江中游干流及洞庭湖出口的年输沙量呈减少趋势，城陵矶至武汉河段河床由淤积转为趋向冲淤平衡；三峡工程初期蓄水运用后，长江中游含沙量沿程恢复距离较长，但床沙质部分恢复距离相对较短。 |
