The shafts for an outfall tunnel in New York required shoring for excavation support and groundwater control. Since there was limited room at site, ground freezing was selected to provide the shoring, instead of a diaphragm wall. Ground temperature monitoring was a critical component, to allow for modeling of the freeze bulbs and to verify when it was safe to begin excavation of the shaft. ...
Disclaimer: This article covers an equation for linear scaling of conductivity sensors to estimate salinity based on the Practical Salinity Scale of 1978 (PSS-78). The equation effectively estimates seawater salinity between the practical salinity ranges of 22 and 42, temperatures 5-35°C, and pressure less than 200 dBar, using a temperature-compensated conductivity sensor. This is not for ...
Evapotranspiration is estimated using the data from a 5-parameter MetOne (MSO) all-in-one multiparameter sensor, a MetOne 370 precipitation gauge, and an Apogee SP-212 pyranometer. ...
