<p>If the OP is interested in environmental studies focused on rivers, s/he should note that this is very much an interdisciplinary field. So, don’t limit your search to school with “environmental sciences/studies” programs, also look for schools with programs/centers in limnology (often in biology, ecology & evolution, or zoology departments), water resources, or hydrology. Relevant majors include environmental sciences; zoology; ecology & evolution; biology; water resources (interdisciplinary, or as hydrology in geography or geology/earth sciences depts., or sometimes combined with soil science in colleges of agriculture); fisheries; environmental chemistry/toxicology; geography; geology/earth sciences. </p>
<p>Since there are no academic programs focused entirely on rivers, you could consider universities that have research centers on rivers as they are likely to offer relevant coursework and research opportunities. Here are some programs/centers focused on “river studies”. Sometimes these are specific to a particular river, so picking a preferred region/location may come into play in your search.</p>
