“…The calculation of water budgets for constructed wetlands and small natural wetlands (surface area <400 km 2 ) has been well documented in the literature (e.g., Koerselman 1989;Becht and Harper 2002;Zhang and Mitsch 2005, Favero et al 2007, Rodrıguez-Rodrıguez et al 2007) while larger wetland ecosystem water budget studies are not as numerous; examples include the Nigerian Hadejia-Nguru wetlands (Goes 1999), Okavango delta floodplain wetlands (Ramberg et al 2006) and the Ortuluakar Marsh in Turkey (Dadaser-Celik et al 2006). Large wetland ecosystems such as the Everglades and the Pantanal possess complexity in hydrological pathways; for instance, evapotranspiration can vary spatially with vegetation type (Camacho et al 1974;Rawson et al 1977, Tardeau andSimonneau 1998) and seasonally with plant phenology.…”

Water budget parameters are estimated for Shark River Slough (SRS), the main drainage within Everglades National Park (ENP) from 2002 to 2008. Inputs to the water budget include surface water inflows and precipitation while outputs consist of evapotranspiration, discharge to the Gulf of Mexico and seepage losses due to municipal wellfield extraction. The daily change in volume of SRS is equated to the difference between input and outputs yielding a residual term consisting of component errors and net groundwater exchange. Results predict significant net groundwater discharge to the SRS peaking in June and positively correlated with surface water salinity at the mangrove ecotone, lagging by 1 month. Precipitation, the largest input to the SRS, is offset by ET (the largest output); thereby highlighting the importance of increasing fresh water inflows into ENP for maintaining conditions in terrestrial, estuarine, and marine ecosystems of South Florida.

“…These values are considerably higher than transpiration contributions in wetlands located in cooler or more mesic places. Evapotranspiration accounted for 13% of a Dutch CTW water budget (Meuleman et al, 2003), 10% for a CTW in Venice, Italy (Favero et al, 2007), and only 3% in a CTW in Missouri, United States (Kadlec et al, 2010). From another perspective, our estimates of summertime transpirational water losses equated to 30-35 mm d −1 while summer water losses via open water evaporation were estimated at roughly 10 mm d −1 (Sanchez et al, 2016).…”

Cities are increasingly pursuing more resilient and sustainable futures. One way to do so is by the increased use of Urban Ecological Infrastructure (UEI), including constructed treatment wetlands (CTW). This strategy is particularly important for aridland cities with scarce water resources. In this paper I synthesize nearly 10 years of systemslevel research at the Tres Rios CTW in Phoenix, AZ, United States. Since July 2011, a research team that includes dozens of student volunteers has been sampling for herbaceous biomass and productivity, water quality, transpiration rates, and aquatic metabolism. We also quantify belowground biomass and plant tissue nutrient content annually, and measured greenhouse gas fluxes from 2012 to 2014. Our peak summer biomass values are among the highest reported in the literature, and high rates of transpiration are associated with this biomass. Using our whole-system water budgets and tracer studies we have documented a slow movement of surface water into the marsh from adjacent open water areas that is driven by transpirational losses and that we refer to as the "biological tide." With our nitrogen (N) budgets for the whole system and the vegetated marsh we showed that roughly 50% of the annual N uptake by the vegetated marsh is driven by new water entering via this biological tide. Our aquatic metabolism sampling suggested that the N uptake associated with the autotrophic water column was roughly 27% of the average annual N uptake by the vegetated marsh. The marsh is a source of CH 4 and N 2 O across the air-water interface and the plants are a net source of CH 4 but a net sink for N 2 O. Our combined flux estimates suggest that the Tres Rios marshes are a net sink for greenhouse gas equivalents because of this plant-mediated net uptake of N 2 O. Finally, over the years our Tres Rios CTW project has provided a platform for dozens of students and young people to experience ecological research, both in the field and in the lab.

“…The water balance method, widely used in past studies (Dierberg et al ., ; Hood et al ., ; McJannet et al ., ), estimates seepage as the residual term. Although, a simplistic approach mathematically, accuracy of water balance method relies heavily on the accuracy of its components (Favero et al ., ; Hill and Neary, ; McMillan et al ., ; Rosenberry and Hayashi, ). Owing to the errors in estimating other components of the water balance equation, seepage computed as a residual term can differ from the actual seepage by more than 100% (Hill and Neary, ).…”

Abstract:A simple method, modified from White's method, was developed and verified for estimating seepage from two stormwater detention areas (SDAs) for 2 years, using night-time changes in surface water levels. The SDAs were located in warm sub-tropical Florida where the assumption of negligible night-time evaporation for White's method does not hold true. Daily seepage was estimated using the nocturnal water level fluctuations on no flow days during winter when evaporation losses were insignificant. Specific yield, rather than the composite specific yield, provided accurate seepage estimates. The average annual seepage from the two SDAs was 2.03 m/year. At almost 70% of surface flows, seepage is a significant contributor to regional surface and sub-surface flows. Comparison of seepage estimates from the night-time method (NM) and the water balance (WB) method showed that the NM-based estimates were within the range of the estimates from the WB method. At SDA1, the differences between the NM and WB estimates were 1% and 11%, for the 2 years. The discrepancy between the two estimates became higher (27% and 23%) at SDA2. Larger differences at SDA2 were because of higher error in quantifying pumped inflows for the WB method. Successful performance of NM combined with its low resource (single well monitoring) requirements will help quantify seepage from detention areas and other similar features (e.g. ponds, constructed wetlands) in warmer climates. A scale-up for the Caloosahatchee River basin showed that seepage from SDA's accounted for 15% of annual river flows indicating the importance of seepage in evaluating water and chemical balances.
