title: Coastal flow topology

description: Simulation of density-dependent, variably saturated flow and salt transport incorporating realistic representations of aquifer heterogeneity was conducted within a Monto Carlo framework to investigate intertidal flow topology and salt dynamics. Our results show that heterogeneity coupled with tides creates transient preferential flow paths within the intertidal zone, evolving fingering-type upper saline plumes beneath the beach surface. Compared to homogeneous systems, multiple circulation cells are generated in the intertidal zone with relatively larger spatial extent, creating hotspots of groundwater velocity at depth in the aquifer. Due to the heterogeneity, strain-dominated and vorticity-dominated flow regions coexist at small spatial scales, which alters the flow topology and local-scale mixing. The areal extent of the flow deformation reaches peaks at high tide and low tide, attributed to tidal action for the former and aquifer heterogeneity for the latter. Results suggest aquifer heterogeneity complicates intertidal flow topology, potentially altering pore-scale mixing and nearshore biogeochemical cycles.

title: The relationship between topography, bedrock weathering, and water storage across a sequence of ridges and valleys

description: Bedrock weathering regulates nutrient mobilization, water storage, and soil production. Relative to the mobile soil layer, little is known about the relationship between topography and bedrock weathering. Here, we identify a common pattern of weathering and water storage across a sequence of three ridges and valleys in the sedimentary Great Valley Sequence in Northern California that share a tectonic and climate history. Deep drilling, downhole logging, and characterization of chemistry and porosity reveal two weathering fronts. At ridgetops, the elevation of each front relative to the channel increases with hillslope length. The shallower front is approximately 7 m deep at the ridge of all three hillslopes and marks the onset of pervasive fracturing and oxidation of pyrite and organic carbon. A deeper weathering front marks the onset extent of open fractures and discoloration. This front is 11 m deep under two ridges of similar ridge-valley spacing, but 17.5 m deep under a ridge with nearly twice the ridge-valley spacing. In all three hillslopes, closed fractures in otherwise unweathered bedrock are found under ridges to at least the elevation of the adjacent channels. Neutron probe surveys reveal that seasonally dynamic moisture is stored to approximately the same depth as the shallow weathering front. Under the channels that bound our study hillslopes, the two weathering fronts coincide and occur within centimeters of the ground surface. Our findings provide evidence for feedbacks between erosion and weathering in mountainous landscapes that result in systematic subsurface structuring and water routing.

title: Hydrogeology and Trout Health, Southeastern Minnesota

description: The recent discovery of resurgent brook trout populations – brook trout present in 68% of southeastern Minnesota streams compared to only 3% in the early 1970s - has led to an increased interest in documenting and improving critical habitat for this native species - the  most temperature-sensitive of southeastern Minnesota’s trout population.    Many of the brook trout analyzed were not associated with known hatchery sources, leading investigators at the Minnesota DNR and University of Minnesota to focus on potentially remnant lineages that have proven their ability to sustain themselves in this region (Hoxmeier, Dieterman and Miller, 2015).  Brook trout often display distinct distributions along stream reaches, thought to be caused by stream temperature, discharge, competition with brown trout, or a combination of all three.  Previous groundwater and geologic investigations, funded in part by the LCCMR, have shown that specific layers within the bedrock provide greater groundwater flow.  Stream reaches that cross these layers are subject to greater groundwater inputs, increased base flow and lower temperature along and downstream from these reaches thus providing habitat conditions supportive to brook trout.

The goal of this project is develop a workable temperature sensing methodology and apply the methodology to candidate trout stream reaches to quantify the changes in temperature, flow, and trout distributions that occur along them.  Advances in temperature measurements using fiber optic cables (distributed temperature sensing, DTS) allow temperature to be recorded through time at regularly spaced intervals, over distances of 1 to  2 kilometers.   Stream reaches to be measured will be chosen based on  geologic mapping by the Minnesota Geological Survey, focusing in areas where different geologic conditions exist and information on trout distribution and abundance are available.  To date, DTS installation, temperature data collection and fish population sampling have been completed at East Indian Creek in Wabasha County.

title: Install fiber optic cable to detect groundwater upwelling in small section of Newtown Creek Canal in New York City. The site has DNAPL contaminants.

description: At a New York study area 1.2 acres of sediment were monitored for evidence of groundwater seeps using a fiber optic distributed temperature sensor (DTS).  A fiber optic cable was installed and monitored, providing 1.0 kilometers of cable laid out in six transects, each approximately 140 m in length and separated by 5-8 m.   The DTS system recorded sediment temperatures at half-meter intervals every 20 minutes in September, 2019, yielding approximately 1.5 million temperature measurements during the study.  Temperature data was analyzed through a suite of analytical methods to identify potential groundwater discharge locations.

title: Cross-boundary Wetland Stewardship in the Greater Rocky Mountain National Park Ecosystem

description: Researchers at Utah State University studied how to facilitate cross-boundary wetland stewardship, using the greater Rocky Mountain National Park ecosystem as a case study. A total of 22 semi-structured interviews were conducted with federal and state agencies, nonprofits, research organizations, and municipalities, as well as an analysis of these organizations’ wetland policies. Interviews consisted of 22 open-ended questions that inquired about the effects of jurisdictional boundaries on wetland ecological processes and conditions, barriers to cooperative wetland management, and the institutional and social contexts in which cross-boundary stewardship efforts operate. The selection of interviewees was based on purposive sampling of participants that work directly on wetland management within the study area. In addition, snowball sampling was used, in which interviewees identified others with special knowledge or experience related to the study questions. Five interviews were conducted in person for participants that were available during field work in July 2019. The remaining interviews were conducted over the phone from August-October 2019. With the consent of interviewees, the interviews were tape-recorded, and notes taken. Interview duration ranged from 30 to 75 minutes. Interviews and field notes were transcribed verbatim. Data analysis involved generating themes from the data by using a systematic, iterative process to of coding in ATLAS.ti, a qualitative analysis computer software program.

title: Agreement and uncertainty among climate change impact models: A synthesis of sagebrush steppe vegetation predictions

description: Ecologists have built numerous models to project how climate change will impact rangeland vegetation, but these projections are difficult to validate, making their utility for land management planning unclear. In the absence of direct validation, researchers can ask whether projections from different models are consistent. Here, we analyzed 42 models of climate change impacts on sagebrush (Artemisia tridentata Nutt.), cheatgrass (Bromus tectorum L.), pinyon-juniper (Pinus L. spp. and Juniperus L. spp.), and forage production on Bureau of Land Management (BLM) lands in the United States Intermountain West. These models consistently projected the potential for pinyon-juniper declines and forage production increases. Sagebrush models consistently projected no change in most areas, and declines in southern extremes. In contrast, projected impacts on cheatgrass were weak or uncertain. In most instances, projections for high and low emissions scenarios differed only slightly.

The projected vegetation impacts have important management implications for agencies such as the BLM. Pinyon-juniper declines would reduce the need to control pinyon-juniper encroachment, and increases in forage production could benefit livestock and wildlife populations in some regions. Sagebrush conservation and restoration projects may be challenged in areas projected to experience sagebrush declines. However, projected vegetation impacts may also interact with increasing future wildfire risk in ways single-response models do not anticipate. In particular, projected increases in forage production could increase management challenges related to fire.

title: Data from Beetle-Moorcroft et al. (2021), Exploring conceptual models of infiltration and groundwater recharge on an intermittent river: the role of geologic controls

description: These data are described in Beetle-Moorcroft, F., Shanafield, M., and and Singha, K. (2021). Exploring conceptual models of infiltration and groundwater recharge on an intermittent river: the role of geologic controls. Journal of Hydrology-Regional Studies, https://doi.org/10.1016/j.ejrh.2021.100814.

Non-perennial rivers and streams are the main surface water resource in arid climates, and streambed infiltration in these systems is a vital component of groundwater recharge.  Subsurface geology controls the extent and location of streambed infiltration and therefore impacts both streamflow and groundwater levels.  This study explores geological controls on groundwater recharge through an intermittent river streambed using scenario evaluation with numerical models constrained by field observations. Our conceptual model included five fundamental variations in the system that could impact where and how much recharge is possible: 1) the presence of a fault; 2) variation in the alluvial aquifer hydraulic conductivity; 3) variation in the thickness of the streambed; 4) presence or absence of a confining unit; and 5) groundwater withdrawals via pumping.  To achieve a realistic outcome, we parameterized the model using field observations from the Alamosa River in Colorado as an example.  Scenarios that changed hydraulic conductivity values resulted in the most notable changes to infiltration, streamflow, and deep aquifer recharge; conversely, variations in streambed thickness had the least impact.  The extent to which streambed infiltration occurs is dependent on streambed properties as well as the hydraulic properties of the underlying alluvial aquifer, and this in turn controls the impacts on streamflow.  This research shows that subsurface heterogeneities are a fundamental control on non-perennial rivers’ hydrogeologic systems and are key to their resilience.
