Comparative Analysis of Different Evapotranspiration Estimation Methods Used in a Raingarden in Auckland, New Zealand
Publication: International Low Impact Development Conference China 2016: LID Applications in Sponge City Projects
ABSTRACT
Raingardens are one of several versatile low impact design (LID) approaches; they have a significant effect on controlling runoff, groundwater recharge, and water quality. Much research has been done on the performance of raingardens (laboratory and field scale). However, most studies have focused on pollutant removal, and there is relatively little research to specifically quantify actual evapotranspiration from a raingarden. Actual evapotranspiration is a major component of the water cycle, but it is difficult to measure evaporation and transpiration directly and separately. For this study, the Hooton Reserve Raingarden (located in Albany, Auckland, New Zealand) was selected as the research site. An overview of hydrological and meteorological field experiments is presented. Although field-based hydrology research is more expensive than computer-based research, and is accompanied by many risks and difficulties, field-based research can bring new fundamental understanding and mechanistic explanations of processes. It thereby contributes to hypothesis development.
