Repairs of concrete irrigation channels in Japan are guided to a large extent by the degree to which their walls have degraded over decades of use. Current methods of estimating Manning roughness coefficients from the roughness of the channel wall are based on linear profiles of arithmetic mean roughness. This study developed a method to estimate Manning roughness coefficients for a planar region directly from the peak-to-peak value of a reflected aerial ultrasonic wave, using a transceiver-base...

According to recent climate projections for South Korea, increases in temperature and precipitation will affect water use and crop production associated with paddy rice cultivation. Impacts are expected on crop growing season, crop varieties, and farming methods, all of which are highly vulnerable to disruption in weather conditions. Previous studies have estimated the effects on agricultural water resources according to climate change scenario, but most do not consider the growing season. In th...

In this study, we focused on the effect of the degree of floc growth on the moving velocity of the interface between sediment of flocculated montmorillonite and supernatant in the semi-dilute suspension, which is characterized by the start of an extremely slow movement of interface followed by an abrupt settling and ending in consolidation. Na-montmorillonite suspension coagulated under different ionic strengths, ranging from 0.5 to 1.5 M of NaCl, was placed in a settling cylinder. The initial h...
