Description
This podcast covers practical examples of using Extrap to for particular field applications including: Bi-directional flow, low flow measurement, tethered boat measurement, narrow channel with rough banks, and a boulder/cobble bed stream. This podcast provides an introduction to the for determining correct extrapolation methods for moving-boat ADCP measurements. The podcast covers: the purpose of the Extrap tool, The shape and distribution of velocity profiles in rivers, how profiles are averaged in WinRiver, how profiles are averaged in Extrap, and provides a detailed description of the Extap interface.
This is part two of a two-part series. For part 1 see "Using Extrap to Determine Proper Extrapolation Methods, General Overview", which provides an overview of the tool, including a detailed description of the Extrap interface.
