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。河流或水库中悬浮泥沙浓度的测量一般采用连续浊度测量法和取样瓶法，本文介绍了一种新型的差压式悬浮泥沙浓度测量系统（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。有漂浮式和水循环式两种，通过在美和大坝、天龙河和黑部河的现场试验，这两种类型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. A floating type and a water circulating type are available, and both of them have shown good performances through field experiments at the Miwa dam, the Tenryu river and the Kurobe river.
