Vast areas in the interior of Australia are exposed to regular but infrequent periods heavy rainfall, interspersed with long at high temperatures, little is known carbon budget these remote or how they respond extreme precipitation. In this study, we applied three methods partition net ecosystem photosynthesis into gross primary production (GPP) and respiration (R e ) during two years contrasting rainfall. The first year was wet (>250 mm above average rainfall), while precipitation fell...
Karst aquifers provide drinking water for 10% of the world's population, support agriculture, groundwater-dependent activities, and ecosystems. These are characterised by complex groundwater-flow systems, hence, they extremely vulnerable protecting them requires an in-depth understanding systems. Poor data accessibility has limited advances in karst research realistic representation processes large-scale hydrological studies. In this study, we present World Spring hydrograph (WoKaS)...
Abstract Seasonal variations in sea level are often neglected studies of coastal aquifers; however, they may have important controls on processes such as submarine groundwater discharge, water intrusion, and discharge to springs wetlands. We investigated seasonal salinity a groundwater‐fed wetland (the RAMSAR listed Piccaninnie Ponds South Australia) found that peaked during winter, coincident with peaks. Closer examination revealed relationship between changes salinity, indicating...
Abstract Carbon‐14 ( 14 C) has been widely used to estimate groundwater recharge rates in arid regions, and is increasingly being as a tool assist numerical model calibration. However, lack of knowledge on C inputs potentially limits its reliability for constraining spatial variability recharge. In this study, we use direct measurements the unsaturated zone develop input map regional scale unconfined aquifer Ti Tree Basin central Australia. The boundary condition 3‐D flow solute transport...
Groundwater-dependent ecosystems are particularly vulnerable to groundwater decline. The South East of Australia has experienced considerable hydrological change due drainage, clearance native vegetation, irrigated agriculture, and forestry. Recent hardwood plantings in the Limestone Coast Prescribed Wells Area (PWA) have increased considerably since 2000, coincident with decline; however, introduction plantations coincided a period lower than average rainfall. Given economic implications...
Abstract. Carbon-14 (14C) is routinely used to determine mean residence times (MRTs) of groundwater. 14C-based MRT calculations typically assume that the unsaturated zone in equilibrium with atmosphere, controlling input 14C activity. However, multiple studies have shown activities are lower than atmospheric values. Despite availability data, no attempt has been made generalise initial depth water table. We utilise measurements from 13 produce a 14C–depth relationship estimate activities....
Abstract The design of wells beneath streams and floodplains has often employed with tall standpipes to prevent incursion surface water into the well during flood events. Here, an approach been presented minimise infrastructure demands in these environments by sealing top (e.g., entering well) monitor total pressure column using absolute (non‐vented) transducer. sealed was tested a laboratory experiment where responses were monitored both unsealed well, while level varied. It is observed...
