title: Water mass balances and hydrologic turnover for six first-order streams in the Holtemme catchment, Germany

description: This repository presents data that come from six first-order streams in the Holtemme catchment (Central Germany) of two different land use types:
a) agricultural streams = Asse, Ströbecker Fließ StF, Silstedter Bach SiB;
b) forested streams = Braunes Wasser BrW, Drängetalbach DrB, Wormsgraben WoG.

Study reaches (csv file with GPS coordinates) were 400m long at each stream and divided into 4 sub-reaches. Consecutive NaCl- tracer additions from seven campaigns during the hydrological year 2019 yielded a total of 458 usable breakthrough curves (BTC) for:
- stream channel water balance (results in data sheet "Mass Balance") and
- subsequent hydrologic turnover calculations (results in data sheet "Hydrol Turnover") with
- additional 61 cases of tracer recovery rates > 100% that were rejected beforehand (results in data sheet "MRec Rejected") but are given here for completeness. 
All in Excel File of repository.

Data from this repository were created for publications emerging from PhD project of Anne Jähkel.

title: Supporting Dataset for "Status of Freshwater Mussels (Unionidae) in the French Creek Watershed, USA at the Onset of Invasion by Round Goby, Neogobius melanostomus"

description: This resource serves as the supporting data for the following publication:  KH Clark, JM Wisor, SJ Mueller, C Bradshaw-Wilson, EW Boyer, and JR Stauffer, Jr.  (2021). Status of freshwater mussels (Unionidae) in the French Creek watershed, USA at the onset of invasion by Round Goby, Neogobius melanostomus. Water, 13(21), 3064; https://doi.org/10.3390/w13213064

Freshwater mussel surveys were conducted in the French Creek watershed of Pennsylvania. Data presented here -- on the contemporary locations of native mussel populations, their abundances, their host fish species, and characteristics of their habitat -- will inform strategies for the conservation of native freshwater mussel species as the invasive Round Goby continues its expansion throughout river networks. The interaction of the invasive Round Goby with indigenous fishes and mussels is shaping an ecosystem transition that has widespread implications for the conservation and management of aquatic ecosystems within the critical zone.

title: Preferential flow between rivers and aquifers in alluvial floodplains

description: Preferential flow between rivers and aquifers in alluvial floodplains may be a core component of shallow groundwater transport and, consequently, its understand- ing is key to modelling and managing groundwater resources. At a clay wedge separating present-day streamflow and bank storage from an adjacent shallow aquifer, we image a suspected sand-dominated structure. This structure cuts through the clay wedge and possesses temporally dynamic electrical resistivity as seen in time-lapse electrical resistivity tomographic (ERT) images collected over a 61-day study period. During days 11–12, following heavy rainstorms, the cross section of the electrically resistive sand fades into the background resistivity structure, reappearing the following day. This research shows that preferential flow can be imaged in time-lapse ERT in buried sand-dominated structures between a floodplain and the adjacent river. Our analysis demon- strates that sand conduits can transport infiltrated rainwater from the floodplain into the river as a bank spring and, hypothetically, at high-stage streamflow, from the river into the adjacent shallow aquifer. In both directions, these conduits for preferential flow exert an important control on the regulation and distribution of water, sediments and contaminants. This phenomenon will help hydrological models to incorporate more real-world phenomena and ultimately better prepare groundwater managers to sustainably steward shallow groundwater resources.

title: Streamflow Regime Changes in Canada

description: Streamflow regime types are identified for the 105 natural Canadian stations using Fuzzy C-Means (FCM) algorithm. The stations are extracted from Reference Hydrometric Basin Network (RHBN, Water Survey of Canada, 2017,  http://www.wsc.ec.gc.ca/) for the period of 1966-2010 to classify streams into a set of six overlapping regime types during the common period. These streamflow regime classes include (1) slow-response/warm-season peak (2) fast-response/warm-season peak (3) slow-response/freshet peak (4) fast-response/freshet peak (5) slow-response/cold-season peak (6) fast-response/cold-season peak. Here, we visualize the shapes of annual hydrographs in the six archetype streams during the baseline period of 1966-1975 and show how they evolve  to the last decadal period of 2001-2010. More information on how the six flow regime types are derived and a detailed description of each regime type can be found in Zaerpour et al. (2020).

title: CRSS-ready Temperature-Adjusted Colorado River Inflows

description: This dataset holds CRSS-ready flow sequences adjusted for temperature increases in the 21st century (2018 to 2100) as well as temperature increases that occurred during the natural flow period from 1906 to 2017.  These flow traces were produced using the methods described in the file memo by Udall (2020).  This study developed six different temperature-adjusted natural flow datasets based on considering three different temperature sensitivities (-3%/°C, -6.5%/°C, and -10%/°C) times two different temperature projections (RCP4.5 and RCP8.5).  The flows were generated by modifying the existing Reclamation natural flow dataset (USBR, 2019) at each of the 29 Colorado River Simulation System (CRSS) natural inflow sites.  Two main steps of temperature adjustment process in this study were: 1- Create a set of natural flows that would have occurred were temperatures constant from 1906 to 2017 assuming 2017 temperatures, and 2- Further adjust downward the constant 2017 temperature flows to account for expected losses due to warming in the 21st century.  The flow data are provided in an CRSS-ready Indexed Sequential Method (ISM) series with a starting year of 2018 and an ending year of 2100.

title: The National Ecological Observation Network Daily Isotopic Composition of Environmental Exchanges (NEON-DICEE) Dataset

description: The National Ecological Observatory Network (NEON) provides open-access measurements of stable isotope ratios in atmospheric water vapor (δ2H, δ18O) and carbon dioxide (δ13C) at different tower heights, as well as aggregated biweekly precipitation samples (δ2H, δ18O) across the United States. These measurements were used to create the NEON Daily Isotopic Composition of Environmental Exchanges (NEON-DICEE) dataset estimating precipitation (P; δ2H, δ18O), evapotranspiration (ET; δ2H, δ18O), and net ecosystem exchange (NEE; δ13C) isotope ratios. Statistically downscaled precipitation datasets were generated to be consistent with the estimated covariance between isotope ratios and precipitation amounts at daily time scales. Isotope ratios in ET and NEE fluxes were estimated using a mixing-model approach with calibrated NEON tower measurements. NEON-DICEE is publicly available on HydroShare and can be reproduced or modified to fit user specific applications or include additional NEON data records as they become available. The NEON-DICEE dataset can facilitate understanding of terrestrial ecosystem processes through their incorporation into environmental investigations that require daily δ2H, δ18O, and δ13C flux data.

title: IntegratingPerspectivesDOCRemovalWhole-StreamMetabolism_Data

description: Quantifying organic carbon (OC) removal in streams is needed to integrate the functional role of inland waters into landscape carbon budgets. To illustrate how in-stream OC removal measurements can be used to characterize ecosystem and landscape carbon fluxes, we compared two common methods: (1) bioassays measuring water column dissolved organic carbon (DOC) uptake and (2) daily rates of whole-stream metabolism and OC spiraling calculated from fluorescent dissolved organic matter, oxygen, and discharge measurements. We then assessed how OC removal rates from these two methods, measured in two low-productivity heterotrophic streams, affected estimates of terrestrial OC loading and export using a mass balance model. OC mineralization velocities calculated from whole-stream metabolism (0.06 ±0.03 m d-1 (mean±SD)) were greater than water column bioassay DOC uptake velocities (0.01 ±0.01 m d-1), which resulted in higher in-stream OC removal estimates (0.5-15.2% and 0.02-4.2% removal for whole-stream metabolism and bioassays, respectively). Furthermore, the terrestrial OC inputs needed to sustain in-stream OC concentrations differ among methods, with simulated inputs ranging from 79-1300 or 3-350 g OC d-1 for whole-stream metabolism or bioassays, respectively. We show how in-stream OC removal can be used to quantify terrestrial-aquatic linkages by estimating OC inputs needed to fuel whole-stream metabolism in low-productivity streams, and offer future directions to better link OC removal with whole-ecosystem OC budgets. Without appropriate conversions to whole-stream processes, bioassays systematically underestimate whole-stream carbon cycling. By integrating whole-stream metabolism with OC transport, we can better elucidate the role of running waters in landscape carbon budgets and the global carbon cycle.

title: Snow Pit Permittivity and Liquid Water Observations - Colorado and New Mexico 2020-2021

description: These datasets summarize field results of snow density, dielectric permittivity, and calorimeter-based liquid water content estimates. The field sites are the Jemez River Basin and Cameron Pass time series sites as part of the NASA SnowEx 2020 and 2021 time series data collection. Snow density observations were made using a 1000 cc wedge cutter and scale with 1 g precision. Dielectric permittivity observations were made with an A2 Photonics WISe sensor with a 325 cc volume of influence. The melt calorimeter observations were made to estimate liquid water content of 20-30 g snow samples taken from the WISe sensor volume; temperature precision was 0.01 degrees celsius and mass 1 g. Two datasets have been quality controlled and assessed to ensure accurate data are being reported. These data include the bulk average density and permittivity during dry snow conditions; and density, permitivitty, and liquid water content during isothermal and wet snow conditions.

title: Earth's Future: Climate change-legacy phosphorus synergy hinders lake response to aggressive water policy targets

description: With mounting scientific evidence demonstrating adverse global climate change (GCC) impacts to water quality, water quality policies, such as the Total Maximum Daily Loads (TMDLs) under the U.S. Clean Water Act, have begun accounting for GCC effects in setting nutrient load-reduction policy targets. These targets generally require nutrient reductions for attaining prescribed water quality standards (WQS) by setting safe levels of nutrient concentrations that curtail potentially harmful cyanobacteria blooms (CyanoHABs). While some governments require WQS to consider climate change, few tools are available to model the complex interactions between climate change and benthic legacy nutrients. We present a novel process-based integrated assessment model (IAM) that examines the extent to which synergistic relationships between GCC and legacy Phosphorus release could compromise the ability of water quality policies to attain established WQS. The IAM is calibrated for simulating the eutrophic Missisquoi Bay and watershed in Lake Champlain (2001-2050). Water quality impacts of seven P-reduction scenarios, including the 64.3% reduction specified under the current TMDL, were examined under 17 GCC scenarios. The TMDL WQS of 0.025 mg/L total phosphorus is unlikely to be met by 2035 under the mandated 64.3% reduction for all GCC scenarios. IAM simulations show that the frequency and severity of summer CyanoHABs increased or minimally decreased under most climate and nutrient reduction scenarios. By harnessing IAMs that couple complex process-based simulation models, the management of water quality in freshwater lakes can become more adaptive through explicit accounting of GCC effects on both the external and internal sources of nutrients.

title: A Novel Framework for Simulating Particle Deposition with Moving Bedforms

description: Previous modeling studies of hyporheic exchange induced by moving bedforms have used a Lagrangian frame of reference, typically a simulation domain that moves with an individual bedform. However, that approach is not suitable for simulating the exchange and accumulation of fine particles at a specific location by the migration of a series of bedforms, which commonly occurs in sand-bed streams. Here we present a novel simulation framework that represents mobile bedforms with a moving-interface domain and determines the resulting hyporheic transport using particle tracking. Simulation results successfully reproduce observations of clay deposition in sand beds, and the resulting development of a low-conductivity layer near the scour zone. Increased bedform celerity and filtration both lead to shallower depth of clay deposition, and a more compact deposition layer. While increased filtration causes more clay to deposit, increased celerity reduces deposition by flattening hyporheic exchange flowpaths.

title: Water management performance curves for economic and environmental benefit

description: Water management usually considers economic and ecological objectives, and involves tradeoffs, conflicts, compromise, and cooperation among objectives. Pareto optimality often is championed in water management, but its relationships with the mathematical representation of objectives, and implications of tradeoffs for Pareto optimal decisions, are rarely examined. We evaluate the mathematical properties of optimized tradeoffs to identify promising regions for compromise, suggest strategies for reducing conflicts, and better understand whether decision-makers are more or less likely to cooperate over environmental water allocations. Cooperation and compromise among objectives can be easier when tradeoff curves are concave and more adversarial when tradeoff curves are convex. “Knees”, or areas with maximum curvature, bulges, or breakpoints in concave Pareto frontiers, suggest more promising areas for compromise. Evaluating the shape of Pareto curves based on each objective’s performance function can screen for the existence of knees amenable to compromise. We explore water management and restorations actions that improve and shift the location and prominence of knees in concave Pareto frontiers. Connecting river habitats and other non-flow management actions may add knees on locally concave regions of Pareto frontiers. Managing multiple streams regionally, rather than individually, can sometimes turn convex local tradeoffs into concave regional tradeoffs more amenable to compromise. Overall, this analysis provides a deep investigation of how the shape of tradeoffs influences the range and promise of decisions to improve performance, and illustrates that management actions may encourage cooperation and reduce conflict.
