“…For each rainfall event, streamflow metrics were calculated to characterize the hydrograph response for each catchment. The streamflow variables include (1) runoff coefficient (unitless) calculated as total runoff divided by rainfall depth for each event; (2) peak flow (mm/h); (3) discharge increase (Δ mm/h) calculated as the difference between peak flow and discharge at the start of the event and (4) lag time (hours) as the time difference between the peak rainfall and peak flow (Beven, 2011; Haque et al, 2022) (Figure 2, Table 2).…”

“…Detailed studies on event scale regulation have been limited due to the lack of high‐resolution hydro‐climatic data (Haque et al, 2022; Manus et al, 2009; Menberu et al, 2018). Existing studies have typically been conducted at either small spatial scales that focus more on individual catchments (McKillop et al, 1999; Palleiro et al, 2014; Streich & Westbrook, 2020; Wilson et al, 2011), or captured a relatively limited number of rainfall events (Haque et al, 2022; Ketcheson & Price, 2011; Lana‐Renault et al, 2014; Sun et al, 2002; Viglione et al, 2010; Wu et al, 2020). These studies have highlighted the important role of factors such as initial conditions and antecedent moisture in influencing hydrological responses, demonstrating a higher responsiveness of streamflow to rainfall events under higher antecedent wetness conditions.…”

“…As a result, the variability in the annual flow patterns is primarily controlled by the impact of snow accumulation and melt, often on frozen soils. Fewer studies have examined event‐scale runoff response during summer and autumn, when runoff is predominantly driven by rainfall events (Haque et al, 2022; Hudson et al, 2021; Wilson et al, 2011). Therefore, studying event‐scale runoff response during summer and autumn offers new insights into how catchment characteristics, antecedent wetness conditions, and rainfall events influence runoff generation during unfrozen conditions.…”

“…Given the uncertain role of peatlands in peak flow regulation, more research is needed on their hydrologic functions. Detailed studies on event scale regulation have been limited due to the lack of high‐resolution hydro‐climatic data (Haque et al, 2022; Manus et al, 2009; Menberu et al, 2018).

Boreal catchments are composed of different land covers, such as forests, peatlands and lakes, which differ in their runoff response to rainfall events. Understanding the individual and combined responses to rainfall events of these different land cover types is crucial for predicting potential impacts of future climate conditions on boreal water cycling. A common assumption is that peatlands attenuate peak flows, which is used as a motivation to restore drained boreal wetlands. However, it remains unclear how and to what extent peatlands can affect peak flow response. Only a few previous studies have looked at the hydrologic dynamics of peatlands in response to specific rainfall events across a wide range of nested sub‐catchments with varying peatland cover. In this study, we use nine years of hourly hydrometric data from 14 catchments within the Krycklan Catchment Study in northern Sweden to examine how peatlands contribute to flood attenuation at both local and stream network scales. Our analysis at the local scale demonstrated that during large events with low antecedent wetness conditions, peatland‐dominated catchment exhibited more muted responses compared to the similar‐sized forest‐dominated catchment. However, during events with high antecedent wetness conditions, the peatland‐dominated catchment exhibited flood magnitudes similar to the forest‐dominated catchment, although the elevated flow condition at the peatland‐dominated catchment persisted for longer periods. Finally, our analysis revealed no significant influence of peatlands on the attenuation or amplification of floods at the stream network scale.

Climate change is projected to impact river, lake, and wetland hydrology, with global implications for the condition and productivity of aquatic ecosystems. We integrated Sentinel‐1 and Sentinel‐2 based algorithms to track monthly surface water extent (2017–2021) for 32 sites across the central United States (U.S.). Median surface water extent was highly variable across sites, ranging from 3.9% to 45.1% of a site. To account for landscape‐based differences (e.g., water storage capacity, land use) in the response of surface water extents to meteorological conditions, individual statistical models were developed for each site. Future changes to climate were defined as the difference between 2006–2025 and 2061–2080 using MACA‐CMIP5 (MACAv2‐METDATA) Global Circulation Models. Time series of climate change adjusted surface water extents were projected. Annually, 19 of the 32 sites under RCP4.5 and 22 of the 32 sites under RCP8.5 were projected to show an average decline in surface water extent, with drying most consistent across the southeast central, southwest central, and midwest central U.S. Projected declines under surface water dry conditions at these sites suggest greater impacts of drought events are likely in the future. Projected changes were seasonally variable, with the greatest decline in surface water extent expected in summer and fall seasons. In contrast, many north central sites showed a projected increase in surface water in most seasons, relative to the 2017–2021 period, likely attributable to projected increases in winter and spring precipitation exceeding increases in projected temperature.
