Master Sample

This sample design is based on master sample: Columbia Basin Master Sample

Details of this master sample:



Frame Definition

Frame

This sample design started with an initial frame of 551,046 sites, based on its master sample. The criteria (based on the master sample's attributes) were then used to refine the sample frame down to 784 sites:

Criteria Group 1
           
  HUC 4 Code (Subbasin) Is Equal To 17060208
AND

Criteria Group 2
           
  Strahler Order Is Equal To 2 OR
  Strahler Order Is Equal To 3 OR
  Strahler Order Is Equal To 4

Target Population

<none>


Panels

Panel designs can help address sampling objectives by increasing the total number of samples at a lower overall cost. A common panel structure involves one or more panels with a high revisit frequency (e.g. an “Annual” panel), and other panels with a lower revisit frequency (e.g. a three year “Rotating” panel).

Stratification

This design uses the following attributes to create the stratification shown below. Each row in the table represents a stratum. This design’s panels are also shown in the table, even if it uses only a single, default panel.
