TL;DR: This commentary addresses a number of related new avenues for research in watershed science, including the use of comparative analysis, classification, optimality principles, and network theory, all with the intent of defining, understanding, and predicting watershed function and enunciating important watershed functional traits.

TL;DR: In this article, the authors compared the observed and predicted streamwater concentration of six solutes (alkalinity, sulfate, sodium, magnesium, calcium and dissolved silica), which are assumed to mix conservatively, and assessed the consistency of the implied hydrograph separation with the hydrological mechanisms that are believed to be operating in this catchment.

TL;DR: In this article, the authors address the following two questions: 1) What are the loads (flux) of nutrients transported from the Mississippi-Atchafalaya River Basin to the Gulf of Mexico, and where do they come from within the basin? 2) What is the relative importance of specific human activities, such as agriculture, point-source discharges, and atmospheric deposition in contributing to these loads?

TL;DR: In this article, a multivariate screening procedure is presented for the evaluation of these potential source solutions, which are groundwater and soil water from different horizons, in the case of stream water.

TL;DR: In this article, a technique is developed whereby stream water can be predicted as a mixture of the observed soilwater classes or end-members, provided that a sufficient set of endmembers has been identified, a least squares technique can be used to estimate the contribution to the stream from each end-member, whenever streamwater samples have been taken.
