Question

Two methods were used to determine the hydraulic conductivity of a sample. The first was the Hazen grain size analysis method, the second was from a large scale pumping test. Match the questions below with the most appropriate answers.
1)Given that different volumes of the aquifer are sampled using the different methods, we would expect? Choose the right answer from the options below in the picture.
2)It was observed that the material was a well sorted, medium sand. What is the most appropriate value of C using the units of (cm.s)-1. Choose the right answer from the options below in the picture.

Choose... The pumping test K to be higher The grain size method K to be higher Both methods should produce the same K measurment 80 to 120 40 to 80

Explanation / Answer
