Course description

Introduction to movement and transformation of substances released in the natural environment. Fundamentals of advection, dispersion and reaction. Aggregation and parameterization of various mixing processes, leading to dispersion at larger spatial and temporal scales. Importance of heterogeneity, anisotropy and stratification in natural media. Basic principles are illustrated by application to atmospheric, river and estuarine pollution problems. Case studies include urban smog, acid precipitation, Chernobyl and Fukushimafall-out, and stratospheric ozone depletion.

Course Format


Academic Honor Code

As always, students are expected to observe all aspects of Dartmouth's Academic Honor Principle, as defined in Organization, Regulations and Courses. In this course, collaboration is allowed during homework preparation, although students have to turn in their individual answers. No collaboration whatsoever is allowed during the mid-term and final examinations. During those assignments, questions can only be directed to the instructor or the TAs.

Dartmouth College policy requires that any apparent violation of the Honor Code be reported to the Committee on Standards. The professor does not have another choice, regardless of how he/she may feel.

Note on laptop use in class

Use of laptop computers is forbidden during class. The only granted exception is to students with documented writing disabilities who need a computer for note taking.

Note to students with disabilities

Students with any type of disability are encouraged to contact the instructor to discuss their needs and what accommodations are necessary. Such contact should be made at the beginning of the term or, in the case of a new condition, as soon as it occurs.
