A Study on the Installation of Measuring Instruments for Early Warning of Small-scale Reservoirs

Abstract

Climate change is causing the collapse of 101 reservoirs due to localized torrential rains and continuous heavy rains. To minimize the damage to human life and property, this article focuses on selecting appropriate local instruments for the efficient maintenance and proper arrangement of these instruments to maximize the efficiency of the early warning and predictive warning systems. In this study, six small-scale reservoirs were studied, and two cases were considered and compared, namely an embankment with a central clay core and a simply earth-filled embankment. The results showed that to predict the collapse of the reservoir by piping, it was considered appropriate to apply 50% of the wetness ratio (<i>l/L</i>) by calculating the wet length (<i>l</i>) on the length (L) of the downstream slope of the embankment. Finally, a methodology was presented for selecting the location of the measuring device.
