“…Historically, the response to these pressures has involved the construction of hard engineering structures such as levees, dykes, seawalls, pumps, and diversion channels to defend vulnerable areas from flooding and/or promote drainage (Day & Templet, 1989). However, the construction, operation, and maintenance of this infrastructure is only viable if it is offset by societal and/or economic returns, such as in the Netherlands (Xu & Blussé, 2019). Consequently, pumped systems are more typically implemented where periodic usage can augment gravity discharge, for example, in parts of Australia (Yang, 2008), the USA (Lang et al., 2010) and Asia (Marfai & King, 2008).…”
