Long-term phosphorus loading and springtime temperatures explain interannual variability of hypoxia in a large temperate lake
Environmental Science & Technology, 1.
MeSH headings : Environmental Monitoring; Eutrophication; Humans; Hypoxia; Lakes; Phosphorus; Temperature
TL;DR:
It is found that a linear combination of decadal total phosphorus loading from tributaries and springtime air temperatures explains a high proportion of the interannual variability in average summertime hypoxic extent, which suggests that the lake responds primarily to long-term variations in phosphorus inputs, rather than springtime or annual loading as previously assumed.

Accelerating Bayesian inference in hydrological modeling with a mechanistic emulator
Environmental Modelling & Software, 7.
TL;DR:
This didactic example uses a model implemented with the hydrological simulator SWMM that allows us to compare the authors' inference results against those derived with the full model, and demonstrates that iterative improvements lead to reasonable results with a very small design data set.

Application of a Discontinuous Form of Macroscopic Gazis-Herman-Rothery Model to Steady-State Freeway Traffic Stream Observations
TRANSPORTATION RESEARCH RECORD, 2672(20), 51–62.
Contributors: I. Ahmed n , B. Williams n & M. Samandar n
TL;DR:
Three constraints justified by the Highway Capacity Manual were applied to fit the model so that the fitted parameters have reasonable and physically interpretable values, and two statistical performance measures verify that the proposed model is preferable to the HCM models both in terms of fit alone and when considering the tradeoff between fit and model complexity.

Contributors: M. Samandar n, B. Williams n & I. Ahmed n
TL;DR:
The model results indicate that WIM technology does increase travel time reliability and provides benefits to both trucking companies and enforcement agencies, and it was also found that increases in the proportion of WIM bypass result in increases in routeTravel time reliability.

Effect of Light Duty Vehicle Performance on a Driving Style Metric
TRANSPORTATION RESEARCH RECORD, 2672(25), 67–78.
Contributors: S. Tanvir n, H. Frey n & N. Rouphail n
TL;DR:
Findings from this study imply that the choice of vehicle does not significantly alter the natural driving style of a driver, and develops a metric for driving style termed “envelope deviation,” which is a distribution of gaps between microscale activity (1 Hz) and fleet average envelope.
