Rietveld refinement. Rietveld refinement is a technique devised by Hugo Rietveld for use in the characterisation of crystalline materials. The neutron and x-ray diffraction of powder samples results in a pattern characterised by reflections (peaks in intensity) at certain positions.
The Corps' 1987 wetland delineation manual has a requirement for comprehensive determinations to quantitatively describe the vegetation in the past 5 years (page 41, Step 5). Revisiting a wetland delineation that is five or more years old does not necessarily mean a new wetland delineation needs to be done. It means it may be necessary to revisit the site to determine whether the delineation is still accurate or needs to be redone based on current conditions.
