What is Hydrology?

Water cycle diagram (NASA)

Hydrology is the study of the distribution, movement, and management of water, which is vital for life. Hydrologists monitor water levels, water flow, rainfall and sediment. Because of increasing pressures due to population growth and changing rainfall and evaporation patterns due to climate change, hydrology is a dynamic and expanding field.

Best General Hydrology Course (PepsiCo)

The Water Cycle is a comprehensive hydrology program available for free auditing. It is divided into ten modules, providing a thorough understanding of both natural water processes and the complexities of managing water resources in a sustainable manner.

Syllabus:

• Introduction to the water cycle
• Basics of hydrology
• Understanding groundwater and models
• Human impacts on freshwater ecosystems
• Water governance and law
• Economics of water infrastructure

This course is part of the Water Stewardship Specialization, which also includes Water Governance & Economics (10-11 hours) and Water Security & Stewardship (9 hours).

If you have taken Coursera courses before, you may notice the user interface is somewhat different for this course. Instead of the steps being labelled “Video”, “Reading” etc, most are “Ungraded Plugin”, which could be a video, slides to click on, or a link. Or even combined steps, with a couple of videos in a single plugin. In my view, this format is more cumbersome.

Why You Should Trust Us

Class Central, a Tripadvisor for online education, has helped 60 million learners find their next course. We’ve been combing through online education for more than a decade to aggregate a catalog of 200,000 online courses and 200,000+ reviews written by our users. And we’re online learners ourselves: combined, the Class Central team has completed over 400 online courses, including online degrees.

How We Made Our Picks and Tested Them

Trying to find “the best” can be daunting, even for those of us who live and breathe online courses. Here’s how I approached this task.

First, I combed through Class Central’s Catalog and the internet to find a variety of free and paid open courses, some with certificates. You don’t need to enroll in a university to learn about hydrology.

When choosing courses, I considered the following factors:

• Instructor experience: I sought instructors with extensive experience in hydrology and engaging presentation styles
• Popularity: I checked numbers of enrollments and views to find popular courses
• Course content: I examined courses that covered a range of topics and presentation styles, including the basics and more advanced topics. I watched some course videos to sample courses I hadn’t already taken
• Learner reviews: I read learner reviews (when available) to get a sense of the quality of each course, leveraging the Class Central database with its thousands of course ratings and reviews written by our users as well as available course provider reviews.

Then, I defined the scope for these recommendations. A hydrology course can cover various topics, so I chose top courses from a range of sub-fields.

Ultimately, I used a combination of data and my own judgment to make these picks of the best hydrology courses. I’m confident these recommendations will be a reliable way to learn about hydrology.
