3 cards from this section. Quick, good the night before a test.
What does 'N' represent in the network adequacy formula?
Think about what we assess for adequate rainfall measurement.
What does the coefficient of variation indicate?
Consider how much data varies around the average.
What is the main purpose of the statistical test in network adequacy?
Focus on what 'network adequacy' means.
True or False: If the actual number of rain gauges is greater than N, the network is inadequate.
Consider what 'adequate' actually reflects in this context.
A region has a coefficient of variation (Cv) of 0.5 and an allowable error of 5%. Calculate the required number of rain gauges and discuss if a network with 10 gauges is adequate.
Remember to square Cv and divide by allowable error.
If a network is found to be inadequate despite having sufficient gauges, what could be potential reasons?
Think critically about where and how gauges collect data.
