Research on Key Technologies of River Rapid Survey by ADCP

ADCP is convenient for field measurements , But the work of data extraction is heavy , and the flow field distribution map and topographic contour map can’t get from the system software directly , so the rapid extraction of measurement data and mapping technology are two key technologies in river rapid survey by ADCP. This paper studies these two issues , proposed solutions, applied these technologies to the measurement of Nanguotou Permeable Pile Groynes on the Yellow River, and achieved satisfactory results.
