TB97: Evapotranspiration from Vegetative Surfaces in Maine

Diurnal evapotranspiration measurements were made over lowbush blueberries and potatoes in Maine during selected portions of the 1977 and 1978 growing seasons. Half hourly measurements were made using a Bowen ratio-energy budget method. Data from these measurements provided the principal energy budget components, an evaluation of potential evapotranspiration, and an array of diagnostic measures used to evaluate the partitioning of available energy into sensible and latent heat. Evapotranspiration rarely reached potential values and a large variability was found to exist. In an attempt to provide a reliable daily estimate of evapotranspiration from potatoes, using a minimum number of environmental measurements, the equilibrium evaporation equation of Priestly and Taylor was examined. A modified version of this equation, incorporating a soil moisture tension term to account for drying soil conditions, was established to predict daily evapotranspiration rates.https://digitalcommons.library.umaine.edu/aes_techbulletin/1104/thumbnail.jp

A decision‐making methodology for risk‐informed earthquake early warning

To maximize the potential of earthquake early warning (EEW) as a credible tool for seismic resilience promotion, it should be combined with next‐generation decision‐support tools that use advanced risk‐based predictions and account for unavoidable malfunctions of the system (i.e., false alarms) to determine whether or not alerts/mitigation actions should be triggered. This work contributes to the required effort by developing a novel end‐user‐oriented approach for decision making related to very short‐term earthquake risk management. The proposed methodology unifies earthquake‐engineering‐related performance assessment procedures/metrics (for end‐user‐focused damage and consequence estimation) with multicriteria decision‐making tools (to consider end‐user preferences toward different types of risks). It is demonstrated for EEW in a hypothetical school building, to specifically investigate the optimal decisions (i.e., “trigger”/“do not trigger” alerts) for a range of earthquake scenarios with varying parameter uncertainties. In particular, it is found that the best action for a given ground‐shaking intensity can depend on stakeholder (end‐user) preferences
