了解流域冲淤量对流域上下游泥沙综合管理具有重要意义。河流、水库悬沙浓度测量一般采用连续浊度法和瓶采样法。本文介绍了一种新型的差压式悬沙浓度测量系统（以下简称SMDP）。由于差压变送器直接测量水的密度，因此SMDP在长时间、高浊度测量中具有优势。根据测量条件，有潜水型和水循环型SMDP，通过在Miwa大坝、天龙河和黑部河的实验室试验和现场试验，这两种SMDP都表现出良好的性能。
It is important to know quantity of wash load for the integrated sediment management from upstream through downstream river basins. Generally, both continuous turbidity measuring and bottle sampling are used for suspended-sediment concentration measurement in rivers or reservoirs. Here, we have developed a new suspended sediment concentration measuring system with differential pressure transmitter (hereafter, we call SMDP). The SMDP has advantages in long-term and high turbidity measurement because differential pressure transmitter is measuring density of water directly. Based on measuring conditions, a submersible type and a water circulating type SMDP are available, and both of them have shown good performances through laboratory tests and field experiments at the Miwa dam, the Tenryu river and the Kurobe river.
