Flood discharge measurement Using ADCP

Discharge measurements not only act as a vital piece of evidence to the national resource database but also become an indispensable source to hydraulic resource planning and developments. Subsequently constant periodical observations need to be made especially to compile crucial high flow data that was laborious and difficult in the past. However, due to the unique characteristics of topography and torrential downpours, Taiwan’s rivers and streams inflate instantly during typhoon seasons, becoming quick-water. Combined with strong winds, these conditions may become a threat to hydrologists. To accurately measure discharges during high flow, therefore, an innovative measuring technique and modernized instruments must be introduced and developed.
