“…In theory, the measurement range of this method can be very large. However, these devices, which use a flask, pycnometer, or constant volume container, are based on the volume–mass replacement method; however, they have not gained widespread acceptance due to inaccurate volume measurements and the influence of temperature (Aggarwal & Tripathi, 1975; Ban et al., 2017; Dahiya et al., 1979; Ma et al., 2016; Papadakis, 1941; Prihar & Sandhu, 1968). Therefore, there is no satisfactory method for on‐site sediment concentration measurement.…”

Soil erosion has long been recognized as a significant threat to the productivity and sustainability of agricultural land (Pimentel et al., 1995). Soil erosion has several negative consequences, decreasing local soil fertility and crop yields. Water pollution and siltation may occur off-site (Cerdan et al., 2010;Colombo et al., 2005). Sediment concentration is required for various purposes, including calculating sediment yield, monitoring soil loss, managing watersheds, and conserving ecosystems (

“…The accuracy of this method was always affected by the following issues during measurement: water surface tension, detained air in water, foams on water surface, as well as water temperature. To solve the above matters, a wide-mouthed pycnometer was used by Aggarwal and Tripathi (1975) under conditions of constant temperature and careful operation. However, the field measurement and certain calcul ation method could not be realized.…”

The measurement of sediment concentration in water is of great importance in soil erosion research and soil and water loss monitoring systems. The traditional weighing method has long been the foundation of all the other measuring methods and instrument calibration. The development of a new method to replace the traditional oven-drying method is of interest in research and practice for the quick and efficient measurement of sediment concentration, especially field measurements. A new method is advanced in this study for accurately measuring the sediment concentration based on the accurate measurement of the mass of the sediment-water mixture in the confined constant volume container (CVC). A sediment-laden water sample is put into the CVC to determine its mass before the CVC is filled with water and weighed again for the total mass of the water and sediments in the container. The known volume of the CVC, the mass of sediment-laden water, and sediment particle density are used to calculate the mass of water, which is replaced by sediments, therefore sediment concentration of the sample is calculated. The influence of water temperature was corrected by measuring water density to determine the temperature of water before measurements were conducted. The CVC was used to eliminate the surface tension effect so as to obtain the accurate volume of water and sediment mixture. Experimental results showed that the method was capable of measuring the sediment concentration from 0.5 up to 1200 kg m−3. A good liner relationship existed between the designed and measured sediment concentrations with all the coefficients of determination greater than 0.999 and the averaged relative error less than 0.2%. All of these seem to indicate that the new method is capable of measuring a full range of sediment concentration above 0.5 kg m−3 to replace the traditional oven-drying method as a standard method for evaluating and calibrating other methods.
