Abstract

Digital elevation models (DEMs) can be used to derive a wealth of information about the morphology of a land surface. Traditional raster analysis methods can be used to derive slope, aspect, and shaded relief information; recently-developed computer programs can be used to delineate depressions, overland flow paths, and watershed boundaries. These methods were used to delineate watershed boundaries for a geochemical stream sediment survey, to compare the results of extracting slope and flow paths from DEMs of varying resolutions, and to examine the geomorphology of a Martian DEM. -Author

Historical changes in streamflows important to diadromous fish in United States coastal regions

Diadromous fish species occupy freshwater habitats (rearing, spawning, migration) for a substantial part of their lives. The quality and quantity of these habitats is mainly driven by thermal and streamflow regimes; therefore, understanding trends in streamflow allows better management of diadromous species and their habitats. We investigated seasonal flows for many basins in two U.S. regions on the Pacific coast and two on the Atlantic coast and computed seasonal trends for eight streamflow metrics for each region from 1973 to 2022 and from 1943 to 2022. In the Atlantic regions, February through May maximum streamflows and frequency and duration of high flows mostly decreased from 1973 to 2022. These trends toward drier conditions coincide with migration windows of multiple diadromous species. Summer low-flow frequency and duration in the two Pacific regions increased (toward drier conditions) in many near-natural basins. More low-flow days can affect species directly through decreased river longitudinal connectivity, which can limit habitat access and food availability. Trends in highly regulated systems differed from trends in near-natural systems, especially in the Pacific regions, because large reservoirs often decrease peak flows and increase low flows. For example, in the southwestern U.S. coastal region, low-flow duration and frequency significantly decreased (wetter) in many regulated basins while near-natural basins were not similarly affected. Our results demonstrate how analysis of environmental flows at regional and seasonal scales can inform future habitat management and restoration plans.

Potential warming-induced changes in stream water sources between proglacial and non-glacial streams, south-central Alaska

Snow and ice-melt are essential for global water resources. Rising air temperatures are causing vegetation encroachment and shrubification of previously snow- and ice-covered landscapes, and precipitation regimes are changing. Collectively, these changes will likely affect the hydrology of mountain environments, although the exact ways in which the hydrology will change are poorly understood. Changing source waters (i.e., the proportion of ice-melt, snowmelt, rain and groundwater) affect the timing and magnitude of streamflow and affect stream temperature, sediment, solute and nutrient fluxes. We investigate spatial and seasonal source water contributions across sub-watersheds of the Nellie Juan River watershed on Alaska's Kenai Peninsula, which differ in glacier cover, elevation and land cover, using a space-for-time approach. To do so, we use a three-endmember mixing model to quantify the contribution of rain, snow/ice-melt and deep groundwater. We show that snow/ice-melt peak later in proglacial streams compared to non-glacial streams. Endmember contributions in non-glacial streams generally vary with elevation and season. We also found that groundwater is a major contributor to streamflow across the study area, contributing between 12% and 47% seasonally, and may become increasingly important as snowpack and ice-melt decrease. This research characterises the shift from a glacierised to a deglaciating landscape through the lens of source water contribution. Broadly, these findings could help improve understanding of how water resources in glacierised watersheds are affected by warming air temperatures.

Revealing tidal pumping processes of alternating groundwater discharge and tidal intrusion using vertical temperature analysis along an estuarine interface

Alternating patterns of groundwater discharge and tidal intrusion along shorelines have remained difficult to characterize and quantify efficiently using empirical data. Groundwater flowpaths along estuarine coastal interfaces have profound effects on dynamic redox conditions, contaminant transport and ecology in estuarine environments. In this study, we quantify tidally influenced groundwater discharge from the McAllister Point Landfill in Newport, Rhode Island, USA using temperature with depth measurements to model bidirectional hydrological fluxes in a recursive estimation state-space model. Zones of groundwater discharge at low tide were first located using thermal infrared and electromagnetic conductivity surveys based on strong contrasts between cooler, more electrically resistive terrestrial groundwater compared to the warmer, more electrically conductive tidal waters that occur in the summer. An array of 25 vertical temperature profilers was subsequently deployed along the southern shoreline of the site, directly adjacent to a landfill. Water samples were collected from discharge zones using a PushPoint sampler with depth, and from surface water away from these zones. Temperature with depth time-series data were used to model one-dimensional alternating groundwater discharge and tidal intrusion dynamics. A nonlinear cross-spectral inversion of the bed temperature data was employed to estimate bulk sediment thermal properties at the same temporal scale as the flux models. One-dimensional hydrological flux models were spatially upscaled via interpolation of fluxes over the southern shoreline area to estimate total volumetric flux. Models of hydrological flux show alternating periods of groundwater discharge at low tide and tidal intrusion into coastal sediments during high tide at a sub-daily scale. Additionally, geochemical analysis of pore waters revealed contrasts in heavy metal concentrations between sampling periods and depth, indicating potential landfill leachate transport. This study represents the use of temperature with depth data to model sub-daily changes in vertical hydrological flux through coastal sediments using a recursive estimation state-space model.
