“…Wetland area within a watershed has been shown to be significantly related to flood control (Mitsch & Gosselink, ) and reduced nitrate concentrations in groundwater and surface water (Phillips, Denver, Shedlock, & Hamilton, ). The type, magnitude, and scale of these functions depend considerably on the degree and mechanism of hydrologic connectivity between wetlands and other landscape elements (Cohen et al, ; Leibowitz, Mushet, & Newton, ; Marton et al, ).…”

Geographically isolated wetlands, those entirely surrounded by uplands, provide numerous landscape‐scale ecological functions, many of which are dependent on the degree to which they are hydrologically connected to nearby waters. There is a growing need for field‐validated, landscape‐scale approaches for classifying wetlands on the basis of their expected degree of hydrologic connectivity with stream networks. This study quantified seasonal variability in surface hydrologic connectivity (SHC) patterns between forested Delmarva bay wetland complexes and perennial/intermittent streams at 23 sites over a full‐water year (2014–2015). Field data were used to develop metrics to predict SHC using hypothesized landscape drivers of connectivity duration and timing. Connection duration was most strongly related to the number and area of wetlands within wetland complexes as well as the channel width of the temporary stream connecting the wetland complex to a perennial/intermittent stream. Timing of SHC onset was related to the topographic wetness index and drainage density within the catchment. Stepwise regression modelling found that landscape metrics could be used to predict SHC duration as a function of wetland complex catchment area, wetland area, wetland number, and soil available water storage (adj‐R 2 = 0.74, p < .0001). Results may be applicable to assessments of forested depressional wetlands elsewhere in the U.S. Mid‐Atlantic and Southeastern Coastal Plain, where climate, landscapes, and hydrological inputs and losses are expected to be similar to the study area.

“…Leibowitz and Vining () characterized the fill and spill dynamics in the PPR as pulsed surface‐water connections limited to periods following spring snow melt (Figure a). Figure b demonstrates what researchers (Barton, Herczeg, Dahlhaus, & Cox, ; Huang, Dahal, Young, Chander, & Liu, ; Leibowitz et al, ) refer to as “fill and merge” dynamics; a nearly continuous surface‐water connection. Figure c conceptualizes surface depression connectivity for a rectangular bottom depression for a PRMS HRU.…”

“…Waterbody connectivity: (a) “fill and spill” and (b) “fill and merge” (from Leibowitz, Mushet, & Newton, ) versus (c) “merge, fill, and spill”; the Precipitation‐Run‐off Modelling System conceptualization for rectangular bottom surface‐water depression. Relevant Precipitation‐Run‐off Modelling System parameters are as follows: dprst_et_coef (fraction of unsatisfied potential evapotranspiration); dprst_seep_rate_open (used in linear seepage flow equation); dprst_flow_coef (used in linear flow routing equation); op_flow_thres (fraction of depression storage above which surface run‐off occurs; any water above maximum open storage capacity spills as surface run‐off); and dprst_depth_avg (average depth of storage depressions at maximum storage capacity)…”

In this study, the Precipitation‐Runoff Modelling System (PRMS) was used to simulate changes in surface‐water depression storage in the 1,126‐km2 Upper Pipestem Creek basin located within the Prairie Pothole Region of North Dakota, USA. The Prairie Pothole Region is characterized by millions of small water bodies (or surface‐water depressions) that provide numerous ecosystem services and are considered an important contribution to the hydrologic cycle. The Upper Pipestem PRMS model was extracted from the U.S. Geological Survey's (USGS) National Hydrologic Model (NHM), developed to support consistent hydrologic modelling across the conterminous United States. The Geospatial Fabric database, created for the USGS NHM, contains hydrologic model parameter values derived from datasets that characterize the physical features of the entire conterminous United States for 109,951 hydrologic response units. Each hydrologic response unit in the Geospatial Fabric was parameterized using aggregated surface‐water depression area derived from the National Hydrography Dataset Plus, an integrated suite of application‐ready geospatial datasets. This paper presents a calibration strategy for the Upper Pipestem PRMS model that uses normalized lake elevation measurements to calibrate the parameters influencing simulated fractional surface‐water depression storage. Results indicate that inclusion of measurements that give an indication of the change in surface‐water depression storage in the calibration procedure resulted in accurate changes in surface‐water depression storage in the water balance. Regionalized parameterization of the USGS NHM will require a proxy for change in surface‐storage to accurately parameterize surface‐water depression storage within the USGS NHM.

“…Vanderhoof and Alexander (2016) explore how lake expansion has influenced wetlands across the landscape of the PPR, in some cases increasing connectivity among aquatic systems, while in others, contributing to the loss of wetland functions when wetlands are entirely subsumed by an expanded lake. At a more localized scale, Leibowitz et al (2016) identify differences between fill-andspill versus fill-and-merge hydrologic processes and differing effects of each on the water chemistry and biotic communities of prairie-pothole wetlands.…”

The multitude of wetlands in the Prairie Pothole Region of North America forms one of Earth's largest wetland complexes. The midcontinent location exposes this ecologically and economically important wetland system to a highly variable climate, markedly influencing ponded-water levels, hydroperiods, chemical characteristics, and biota of individual basins. Given their dominance on the landscape and recognized value, great interest in how projected future changes in climate will affect prairie-pothole wetlands has developed and spawned much scientific research. On June 2, 2015, a special symposium, BMidcontinent Prairie-Pothole Wetlands: Influence of a Changed Climate,^was held at the annual meeting of the Society of Wetland Scientists in Providence, Rhode Island, USA. The symposium's twelve presenters covered a wide range of relevant topics delivered to a standingroom-only audience. Following the symposium, the presenters recognized the need to publish their presented papers as a combined product to facilitate widespread distribution. The need for additional papers to more fully cover the topic of prairie-pothole wetlands and climate change was also identified. This supplemental issue of Wetlands is the realization of that vision.
