“…Niazi et al. (), using groundwater chloride concentrations, estimated that the groundwater recharge rate varies spatially from 7.5 mm/year to 37 mm/year and the bedrock saturated hydraulic conductivity varies spatially between 0.003 and 0.085 m/day within the west portion of the Nose Creek watershed.…”

“…For example, Barker et al (2011), using a water-balance method, suggested that the groundwater recharge rate within the Nose Creek watershed varies spatially between 5 and 50 mm/ year. Niazi et al (2017), using groundwater chloride concentrations, estimated that the groundwater recharge rate varies spatially from 7.5 mm/year to 37 mm/year and the bedrock saturated hydraulic conductivity varies spatially between 0.003 and 0.085 m/ day within the west portion of the Nose Creek watershed.…”

Wetland protection and restoration strategies that are designed to promote hydrologic resilience do not incorporate the location of wetlands relative to the main stream network. This is primarily attributed to the lack of knowledge on the effects of wetland location on wetland hydrologic function (e.g., flood and drought mitigation). Here, we combined a watershed‐scale, surface–subsurface, fully distributed, physically based hydrologic model with historical, existing, and lost (drained) wetland maps in the Nose Creek watershed in the Prairie Pothole Region of North America to (1) estimate the hydrologic functions of lost wetlands and (2) estimate the hydrologic functions of wetlands located at different distances from the main stream network. Modeling results showed wetland loss altered streamflow, decreasing baseflow and increasing stream peakflow during the period of the precipitation events that led to major flooding in the watershed and downstream cities. In addition, we found that wetlands closer to the main stream network played a disproportionately important role in attenuating peakflow, while wetland location was not important for regulating baseflow. The findings of this study provide information for watershed managers that can help to prioritize wetland restoration efforts for flood or drought risk mitigation.

The accurate measurement of shallow flow velocities is crucial to understand and model the dynamics of sediment and pollutant transport by overland flow. In this study, a novel triple-tracer approach was used to re-evaluate and compare the traditional and well established dye and salt tracer techniques with the more recent thermal tracer technique in estimating shallow flow velocities. For this purpose a triple tracer (i.e. dyed-salted-heated water) was used. Optical and infrared video cameras and an electrical conductivity sensor were used to detect the tracers in the flow. Leading edge and centroid velocities of the tracers were measured and the correction factors used to determine the actual mean flow velocities from tracer measured velocities were compared and investigated. Experiments were carried out for different flow discharges (32-1813 ml s À1) on smooth acrylic, sand, stones and synthetic grass bed surfaces with 0.8, 4.4 and 13.2% slopes. The results showed that thermal tracers can be used to estimate shallow flow velocities, since the three techniques yielded very similar results without significant differences between them. The main advantages of the thermal tracer were that the movement of the tracer along the measuring section was more easily visible than it was in the real image videos and that it was possible to measure space-averaged flow velocities instead of only one velocity value, with the salt tracer. The correction factors used to determine the actual mean velocity of overland flow varied directly with Reynolds and Froude numbers, flow velocity and slope and inversely with flow depth and bed roughness. In shallow flows, velocity estimation using tracers entails considerable uncertainty and caution must be taken with these measurements, especially in field studies where these variables vary appreciably in space and time.

Estimar os valores de recarga das águas subterrâneas é importante para entender a dinâmica de sistemas aquíferos perturbados por forçantes climatológicas e pelo uso e ocupação da terra. Este trabalho estimou as taxas de recarga das águas subterrâneas pelo método da variação da superfície livre em área do Sistema Aquífero Bauru (SAB) para a Estação Ecológica e na Floresta Estadual de Santa Barbara nos anos hidrológicos 2014/2015 e 2015/2016. Durante esse período a região passou por dois períodos climáticos distintos: um ano considerado normal (com taxas de precipitação em torno da média histórica dos últimos 30 anos) seguido de um ano com a presença do fenômeno ENOS (El Niño Oscilação Sul) aumentando a precipitação em 35,44% quando comparado ao ano anterior. Os resultados demonstraram, apoiados na espacialização do fenômeno pela área estudada, que apesar das diferenças nas taxas de precipitação, o percentual de recarga foi o mesmo para os dois anos, não evidenciando diferenças entre as áreas com vegetação de Cerrado e reflorestamentos com espécies exóticas como Pinus e Eucalipto.
