syntheticdv2lff, Scripts for low-flow frequency (LFF) estimation (and bias correction) from daily mean streamflow estimated at level-12 hydrologic unit code (HUC12) pour points in the southeastern United States syntheticdv2lff, Scripts for low-flow frequency (LFF) estimation (and bias correction) from daily mean streamflow estimated at level-12 hydrologic unit code (HUC12) pour points in the southeastern United States
The syntheticdv2lff repository contains R language source code that document the workflow to compute low-streamflow (low-flow) frequency (LFF) statistics from previously estimated streamflow at level-12 hydrologic unit code (HUC12) pour points (watershed outlet locations) in the south-central and southeastern United States for 1950 through 2010 and associated bias correction. LFF...

WRTDSplus: Extensions to the WRTDS method. WRTDSplus: Extensions to the WRTDS method.
For some sites and constituents the three dimensions of the Weighted Regressions on Time, Discharge, and Season (WRTDS) model do not capture all the important aspects of water quality variability. For example, in some locations hysteresis or antecedent flow conditions are important influences on water quality concentration and loads. In other places, daily flow is less predictive than...
MapMark4 Version Update (Version 1.1) MapMark4 Version Update (Version 1.1)
MapMark4 is a software package originally released by Ellefsen (2017) that implements the probability calculations in three-part mineral resource assessments (Singer and Menzie, 2010). The name is derived from the descriptive phrase “mineral assessment program mark4”—the name “mark4” is chosen because the previous, similar program was called “mark3”. Functions within the software package...
Landscape transcriptomic analysis detects thermal stress responses and potential adaptive variation in wild brook trout during successive heatwaves Landscape transcriptomic analysis detects thermal stress responses and potential adaptive variation in wild brook trout during successive heatwaves
Extreme weather events, such as heatwaves, are becoming more frequent and intense as a result of climate change. Importantly, such extreme weather events can be more important drivers of extirpation and selection than changes in annual or seasonal averages and they pose a particularly large threat to poikilothermic organisms. In this study, we evaluate the thermal stress response of a...
pfdf 2.0.0 pfdf 2.0.0
This release substantially improves support for working with datasets in a mix of coordinate reference systems. The release also introduces new classes for working with spatial metadata, adds confidence intervals to the Gartner 2014 volume model, adds support for additional unit systems, and improves the user experience when filtering the stream segments in a network.
