Its main work includes the Yellow river sediment cross-section tests, river bed surface quality sampling and particle size distribution analysis and so on.
其主要工作内容包括黄河河道断面淤积测验，河道表层河床质取样及颗粒级配分析等工作。
The water surface level, velocity field and sediment concentration field of gravel sand bed and sand bed reach on Jianjiang river were refined simulated.
细致地模拟了荆江卵石夹沙河床及沙质河床浅滩河段的水面线、流速场、含沙量浓度场及河床变形。
The measured data show that the bedload sediment transport rate is related more closely to the effective stream power within the bed-surface layer than to the river stream power.
实测资料表明，推移质输沙率与床面层内有效水流功率有良好的相关性，且高于推移质输沙率与水流功率的相关性。
The results have shown that using this method to mine the ore body will not affect the stability of the surface river bed.
结果表明，用该采矿法开采矿体时不会影响地表河床的稳定性。
