The Hydrology Class 2022 - The schedule

This post contains the foreseen schedule of the course. Material uploaded is subject to modifications prior to the schedule date. All the lectures will be to students present in blended format. Meaning that students can be either present or attend remotely. All of them will be recorded and uploaded to web.

Topics in bold are definitive. Topics in normal characters are still subject to modifications.  All the 2022 videos will be available at this Vimeo Showcase.

In this part of the class we describe where it rains and how much it rains using statistical concept. One important objective is to understand what are the extreme precipitations for their importance in engineering.

Once precipitations arrive to the ground surface they either infiltrate or generate runoff. We first state how they infiltrate and, actually how water behave in the soil and in the ground. We talk about the complexity of the Earth surface that contains life and call it, the Critical Zone. To study infiltration we introduce the Darcy and Richards equations of which we explain the characteristics.

    Once the rainfall gains the terrain, it can infiltrate or producing runoff. In the next we discuss the main mechanisms that produce runoff.

    2020-03-29 - The surface water propagation (a brief Storyboard 2021)

    Runoff moves on the surface of the terrain according to the de Saint-Venant equation. In the following the equation is derived in the 1D case.

    Evaporation generalities 

    A consistent part of root zone and surface water evaporates and returns to the atmosphere to eventually form clouds and precipitation again. The process follows quite complicate routes and is different when happening from liquid surfaces, soil or vegetation (and BTW animals).  In this group of lectures we try to figure out the physical mechanisms that act in the process and give some hint on methods to estimate evaporation and transpiration with physically based models.
