The course deals with the principles of hydrology of catchment areas, rivers and deltas. The students will learn:
1). to understand the relations between hydrological processes in catchment areas 2?. to understand and to calculate the propagation of flood waves 3). to understand hydrological processes in deltas 4). to draft frequency analysis of extremes under different climatological conditions.

In Indiana, major rivers and their tributaries cross much of the state. These rivers can produce significant hazards related to flooding and erosion, which threaten nearby residents and infrastructure. Rivers are dynamic landforms, and they naturally shift their position on the landscape over time. The path of a river may change rapidly during a flood, or it may slowly evolve over long periods of time. In this exercise, students use hillshade images derived from airborne lidar (light detection and ranging) from a section of the White River in Indiana to map how the river has changed over the span of five years. Students learn to identify and describe how river meanders and oxbow lakes evolve by comparing the form of the river from 2013 and 2018. Students also use the lidar hillshade to evaluate the longer-term evolution of the river's form and assess how local infrastructure may be impacted. Students are additionally given a plot of river discharge measured from a stream gage station just north of the mapped section of river. They learn how to evaluate changes and trends in river discharge and assess how river discharge can be related to river morphology.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"Studying the microbes present in meanders — the bendy, curvy paths of rivers — may prove to be a way of understanding much larger processes happening on the scale of entire watersheds. That’s the finding of a new study by researchers at the University of California Berkeley. Scientists tested the idea that floodplain soils share a core microbiome that can be used to predict biogeochemical processes in watersheds. The group analyzed soil samples from the upper, middle, and lower parts of Colorado’s East River. While the specific microbes from the various sections of the river differed, there was a core set of shared microbial activity across the three meanders. This included microbiomes enriched for aerobic respiration, aerobic CO oxidation, and thiosulfate oxidation with the formation of sulfur. The results suggest that meander-bound floodplains serve as functional zones that might be able to predict biogeochemical transformations in riparian zones..."

This outdoor investigation involves students observing, recording, comparing and pondering the differing landscapes and rocks located along a river. Follow-up class sessions involve student generation of investigable questions, student-generated studies with required write-up and a mapping activity.

Students are given the opportunity to learn a process-based approach to river research, by developing research questions about river form and function in Maine. Students filmed themselves while collecting and analyzing their data. The final product is a 6-minute video, created in Final Cut Pro X, that contained a description of their project,their hypotheses, analysis/results, and conclusions.

This unit is designed to help second grade level students develop an understanding of the effects of weathering and erosion caused by water, specifically the creation of identifiable landforms. Students will explore and test the creation of a variety of landforms using both a community stream table and personal stream tables. Students will be able to conduct a series of investigations related to water erosion. This unit focuses on these specific landforms: braided channel, canyon, cliff, delta, meandering stream, oxbow lake, and valley. Students will also use Google Earth to explore the location of these types of landforms both locally and globally.

This class serves as an introduction to mass transport in environmental flows, with emphasis given to river and lake systems. The class will cover the derivation and solutions to the differential form of mass conservation equations. Class topics to be covered will include: molecular and turbulent diffusion, boundary layers, dissolution, bed-water exchange, air-water exchange and particle transport.

The course material emphasizes mathematical models for predicting distribution and fate of effluents discharged into lakes, reservoirs, rivers, estuaries, and oceans. It also focuses on formulation and structure of models as well as analytical and simple numerical solution techniques. Also discussed are the role of element cycles, such as oxygen, nitrogen, and phosphorus, as water quality indicators; offshore outfalls and diffusion; salinity intrusion in estuaries; and thermal stratification, eutrophication, and sedimentation processes in lakes and reservoirs. This course is a core requirement for the Environmental MEng program.
