A comparative study was performed to assess if open borehole temperature logging or above ground temperature measurements from multi-level pumping test could be used to gain representative temperature profiles in unconfined coastal aquifers.

Abstract
A comparative study was performed to assess if open borehole temperature logging or above ground temperature measurements from multi-level pumping test could be used to gain representative temperature profiles in unconfined coastal aquifers. But if precise temperature profiles are needed (e.g. modeling purposes), the only robust method is the online temperature measurement within an isolated portion of the well purged with a pump. This is the most reliable method that could be applied to existing long screen piezometers, if more expensive multilevel ground temperature sensor loggers are not availableFile in questo prodotto:
