Continental-scale isotope hydrology
… dissertation outlines several applications of isotope hydrology to address four previously unknown questions involving surface- and ground-water resources at regional- to continental-spatial scales over contemporary- to millennial-temporal scales. The four chapters in this dissertation …

Stable isotope hydrology of the Table Mountain group
… from mixing during groundwater flow. Rainfall isotope composition is negatively correlated with continentality, as defined by the product of distance to the Atlantic and the closest coast. Isotope composition of rainfall is also strongly negatively correlated with altitude. Sites that are …

Isotope hydrology of Lehman and Baker creeks drainages, Great Basin National Park, Nevada
Environmental isotope techniques have been used to study the water resources in Great Basin National Park in Nevada in an attempt to understand the recharge and mixing characteristics of the creeks, lakes and shallow groundwater in the park. The results have been used to trace the sources of the …

Assessing the contribution and variations of spring discharges to river flows within the Nuwejaars Catchment, Cape Agulhas
… topography, lithology, aquifer characteristics, hydrology and climatic conditions. As such, quantifying and understanding the hydrological effects of these factors is crucial for effective water resource management as it reflects changes in water fluxes and storages within the hydrological cycle. …

Identifying control points of excessive nitrate load in a pastoral catchment to support lake management
… losses in the pastoral catchment. Multi-isotope analysis, high-frequency data collection, and modelling were utilised in identifying and describing potential nitrate sources and biogeochemical transformations involved that affect nitrate export from catchment to receiving waters. A …

Characterization of legacy soil P and quantification of subsurface losses under artificial drainage
… dissertation, we applied methods in chemical and isotope hydrology, soil chemistry and physics, and agronomy to better understand the risk of P mobility and loss through subsurface pathways in soils with a history of P amendment. The objectives of this dissertation project were to: 1) characterize …

Characterizing Hydrological Balance and Hydrochemistry of a Chronosequence of Newly Formed Wetlands within the Athabasca Oil Sands Region using Isotopic and Geochemical Tracers
… methods difficult to implement, so stable isotopes and geochemical tracers were used to infer the water balances. Isotope hydrological balances measured as Evaporation: Inputs ratio (E/I) varied significantly among wetlands on the two types of landscapes. Ratios for wetlands found on-lease …
