Bankfull geometry data at 22 United States Geological Survey stream flow gaging sites in the Red River Basin of Minnesota and North Dakota were used for developing regression estimates of flows of different return periods.
For more detailed survey of flow structure neutrally buoyant particles are employed.
The paper examined the critical headway and following time by the modified drew method and the survey traffic flow data on-site.
Figure 1 presents the survey's flow chart.
While continuous surveys might have some advantages over periodic cross-sectional surveys, the flow of so much data without improved structures to use the results is potentially wasteful, and such an approach does not truly test the I-Q concept.
This paper reports the application of a special acoustic sensor device to quantitatively survey sand water flows in a pipeline.
They are very widely used, but often stem from local initiatives, and they are seldom managed at national level (unlike, for example, the North-American Commodity Flow Survey, which is a shipper-based survey; or the European national road freight surveys, which are carrier based, with methodologies and data harmonised by Eurostat [12, 13]).
Although the measured depth to water is slightly different from that estimated from geo-electric survey, the expected flow net map gives consistent hydrological information about groundwater flow direction in the site.
The United States Geological Survey monitored the flow of Little Butte Creek at seven different stream gauges: two on the south fork, three on the north fork, and two on the main stem.
Flow survey at the rotor exit shows distinct behaviors of the aerodynamic parameters in the tip region at near stall flow condition.
