Base Flow Recession Analysis for Streamflow and Spring Flow
<p>Base flow recession curve during a dry period is a distinct hydrologic signature of a watershed. The base flow recession analysis for both streamflow and spring flow has been extensively studied in the literature. Studies have shown that the recession behaviors during the early stage and the …

Simulating the Cost and Legacy N Reduction Potential of Denitrifying Spring Bioreactors Installation in the Chesapeake Bay Watershed
… loading to the Bay is legacy N from groundwater springs. Denitrifying spring bioreactors are a best management practice that offers an opportunity to abate N from groundwater springs. The objective of this research is to estimate the regional abatement costs to remove legacy N using bioreactors. …

Habitat Modeling of Three Endemic Crayfish Species in the Black River Drainage of Missouri and Arkansas: Factors Affecting Distribution and Abundance
… related to stream size, current velocity, and spring discharge. Orconectes marchandi presence was predicted primarily by dolomite geology and water chemistry metrics, both of which may be related to spring flow volume. Cambarus hubbsi was associated with factors related to stream size and …

Dynamic Sensing of a Dynamic System: Mobile Water Quality Monitoring at Spring Lake, San Marcos, Texas
… into the patterns and drivers of variability in Spring Lake and comparable karst systems. From June 22, 2022, to June 11, 2023, a solar-powered continuous monitoring device mounted by Spring Lake staff on the stern of the 1953 glass-bottom tour boat automatically collected water-quality …

Groundwater management using a GIS case study : Uitenhage Subterranean Government Water Control Area
… The most wellknown of this manifestation are the springs at Uitenhage which have been used since pre-historic times and are currently a principal source of water for the municipal supply. At the turn of the 20th century, with the introduction of drilling machines into the area a number of …

Can run-of-river hydropower meet the needs of the north? A case analysis of the Albany River watershed
… change on this watershed suggests annual streamflow increases of at least 15% into the next century, distributed unevenly across the seasons with winter and spring flow increases of +45.7% and +27.7%, respectively and summer and fall decreases of -38.0% and -5.2%, respectively. Hydropower …

Assessing the contribution and variations of spring discharges to river flows within the Nuwejaars Catchment, Cape Agulhas
… South Africa has not stressed the importance of springs as a water resource and fails to integrate surface water and groundwater as one essential resource functioning interchangeably. The investigation of springs as a water resource is a way of understanding the integrated manner in which …

Delineating contributing areas for karst springs using NEXRAD data and cross-correlation analysis
The use of cross-correlation analysis on spring discharge and precipitation data in karst aquifer basins has been used for many years to develop a conceptual understanding of an aquifer and estimate aquifer properties. However, to this point, the application of these processes has relied on gaged …

On the dynamics of shallow water currents in Massachusetts Bay and on the New England continental shelf
… Massachusetts Bay show that freshening from the spring runoff dominates the low frequency currents and the hydrography of the Bay in the spring months. The major freshening is attributed to the Merrimack River which empties into the Gulf of Maine 30 km to the north of the Bay; discharge of the …

Quantifying the Impact of Climate Change on Water Availability and Water Quality in the Chesapeake Bay Watershed
… will result in moderate increases in winter/spring flow (2.7±10.6 %) and NO3- export (3.0±7.3 %), substantial increases in dissolved P (DP, 8.8±19.8 %), total P (TP, 4.5±11.7 %), and sediment (17.9±14.2 %) export, and greater N2O (63.3±50.8 %) and N2 (17.6±20.7 %) emissions. Conversely, …
