Episodic Increases In Stream Acidity, Catchment Flow Pathways And Hydrograph Separation
… used to calibrate hydrological models. Isotope Hydrograph Separation (IHS) divides storm runoff into components of new rainwater and "pre-event water" which was in the catchment prior to a storm event. Such data can be used to improve the calibration of SWA model hydrology, but IHS usually shows …

Using Nutrients, Sediment, Ions, Isotopes, and Hydrograph Separation to Quantify Conduit-Dominated Recharge Processes in a Trinity Aquifer Site: Cave Without a Name
Cave streams provide an ideal location for sampling waters transported through a karst system because they integrate basin-wide sources ranging from fast flow in conduits to slow flow through the bedrock matrix. Although numerous studies have monitored cave streams to characterize these process, …

Old and subsurface water contributions to storm runoff generation in flat, fractured, clayey terrain.
… from two experimental plots. Chemical hydrograph separation results indicate that the subsurface water contributions were between 16-72% of the peak discharge and between 35-95% of the total runoff volume. Isotopic hydrograph separation results indicate that the old water contributions …

Recharge dynamics of a perched phreatic aquifer
… using fluid mass balance (FMB), integrated hydrograph separation (IHS), and innovative hydrograph manipulation techniques. Timing and mechanisms of recharge were analyzed using signal-processing and linear-system approaches. Hydrometeorologic and hydrologic data were collected for a 16-month …

The influence of urbanization on runoff generation and stream chemistry in Massachusetts watersheds
… U.S. watersheds (r2 = 0.60; n = 158 watersheds). Hydrograph separation in an intensively-studied 3.9 km 2 catchment indicates that surface flow paths are critical to stormflow generation during rainfall events in urbanizing catchments. Elevated discharge is largely composed of new water, with …

Characterization of legacy soil P and quantification of subsurface losses under artificial drainage
… use concentration-discharge (C-Q) relationships, hydrograph separation, and the seasonal origin index (SOI) to identify pathways of subsurface P loss in a ditch-drained field. ☐ Chapters 2 and 3 focused on characterizing the sources and solubility of soil P to predict the risk of P loss. The X-ray …

Biogeochemical Consequences of Hydrologic Conditions in a Tropical Montane Rain Forest in Ecuador
… soil. Results from an isotope two-component hydrograph separation for the three microcatchments showed that new rain water ('event water') contributed 44-81 % to the total stormflow runoff during one selected peak discharge. The canopy was a small and the organic layer the major source of …
