Abstract

ABSTRACT

Conventional floodgate operation is considered inefficient, while the application of IoT based technology with MPPT control on solar panels for floodgate automation systems is still rarely studied. In addition, studies on the relationship between the height of automatic floodgate opening and flow characteristics in open channels are still limited, and the use of solar energy in floodgate control systems has not been optimized optimally. The purpose of this study was to analyze the effect of the height of the automatic water gate on the resulting discharge, as well as to calculate the Froude number (Fr) and Reynold number (Re) to determine the flow characteristics that occur in the open channel. This study uses an experimental method on a laboratory scale which requires testing and measuring each variation in the height of the water gate opening. The results of this study are 1) The effect of the heigt of the floodgate opening, the smaller the resulting discharge in the downstream part of the channel, while after is an increase in discharge. 2) the flow characteristics that occur in open channels from upstream to downstream are dominated by laminar flow (Re<500), whilein the upstream the flow is subcritical (Fr<1) and after the gate is opened to the downstream the flow is supercritical (Fr>1). And 3) a higher opening of the water gate will lead to an increase in the resulting discharge coefficient.
