A hazard-based risk analysis approach to understanding climate change impacts to water resource systems: application to the Upper Great Lakes
Risk Robustness Water resources
2014/10/31
Water resources systems are designed to operate under a wide range of potential climate conditions. Traditionally, systems have been designed using stationarity-based methods. Stationarity is the assu...
Assessing nonpoint-source nitrogen loading and nitrogen fixation in lakes using δ15N and nutrient stoichiometry
Assessing nonpoint-source nitrogen loading nitrogen fixation lakes using δ15N nutrient stoichiometry
2014/4/3
Runoff from human-dominated watersheds has greatly altered nitrogen (N) and phosphorus (P) cycling in lakes. Nutrients from human sources are distinct from those from undisturbed ecosystems in several...
