PROBLEM TO BE SOLVED: To provide a measurement apparatus and a measurement method for flow condition to improve the operability for towing a mobile measurement instrument on the water, the safety, the certainty and the measurement accuracy. SOLUTION: The measurement apparatus 2 for flow condition comprises: a towing apparatus 3 movable on the water in a river 1; a towing member 4 connected to the towing apparatus 3 at one end, and freely suspended on the water in the river 1 at the other end; and a stream regime measurement means 13 provided in the towing apparatus 3, and measuring a stream regime in the river 1. Since a first tension adjustment means 5 for applying a tension to the towing member 4 is provided in the towing apparatus 3, the towing apparatus 3 can be towed without loosing the towing member 4. The towing member 4 is prevented from being loosed, contacting the water and being pulled by flowing water and driftwoods. The towing apparatus 3 is safely towed. Additionally, the towing apparatus 3 is smoothly towed by the towing member 4, and the certainty for measuring the stream regime and the measurement accuracy can be improved by overcoming a looseness of the towing member 4.
