17-24. Evaluation of different frameworks and methods for model integration for application to the National Water Model

The interdisciplinary nature and increasing complexity of environmental and water-resource problems require the use of modeling approaches that can incorporate knowledge from a broad range of scientific disciplines. Selection of models and methods to address these problems is difficult given the large number of available models and the potentially wide range of application, data constraints, and spatial and temporal scales of application.

We seek a Mendenhall Fellow to investigate frameworks in which to focus multidisciplinary research and operational efforts, allowing scientists and engineers in a variety of disciplines and across multiple agencies to work cooperatively on multidisciplinary problems. Each developer can create and test models in their own areas of expertise; however, integrating their efforts with those in other domains will require a technical framework. In addition, as research provides improved model components, these can be used to modify or enhance existing operational models by inserting or replacing physical process algorithms.

Some examples of the types of framework that may be relevant to this evaluation are:

  1. Common modeling infrastructures and application programming interfaces (e.g., Earth System Modeling Framework; and the Community Surface Dynamics Modeling System;
  2. “Micro services” and cloud based approaches (Docker;,  Cloud Services Integration Platform;
  3. High performance computer message passing methods within standard coding languages (Message Passing Interface; and OpenMP;
  4. Other specialty, domain specific, or proprietary frameworks (Flood Forecasting System, Community Hydrologic Prediction System, HydroShare; , and (or) EarthCube;
  5. Any other framework or modeling system that the postdoctoral researcher finds interesting or applicable.

Proposed Duty Station: Lakewood, CO

Areas of Ph.D.: Hydrology, environmental engineering, or computer science (candidates holding a Ph.D. in other disciplines, but with extensive knowledge and skills relevant to the Research Opportunity may be considered).

Qualifications: Applicants must meet one of the following qualifications: Research Hydrologist, Research Engineer. (This type of research is performed by those who have backgrounds for the occupations stated above. However, other titles may be applicable depending on the applicant's background, education, and research proposal. The final classification of the position will be made by the Human Resources specialist.)
