Invited Lecture for the new master’s program of the University of Arizona - Hydrology and Atmospheric Sciences

September 12, 2025

Fluid Dynamics - Bernoulli's Lecture, University of Arizona, Tucson, Arizona

Dr. Peter Troch invited me to teach a class for the new master’s program of UofA about fluid dynamics, in particular about the derivation of Bernoulli’s equation from fundamental laws of energy and momentum conservation. I personally enjoyed the lecture and received valuable feedback from the students. Slides of my part are available Here.

HydroPol2D short course for the graduate students of UTSA

November 21, 2024

Research Talk, University of Texas at San Antonio, San Antonio, Texas

A HydroPol2D course was given on Tuesday and Thursday in Dr. Giacomoni’s class at UTSA. I showcased the derivation of HydroPol2D, including governing equations, model applications, the automation of GIS processing with Google Earth Engine, and the application of HydroPol2D for flood inundation mapping. Recorded classes, including slides (100+) available in the HydroPol2D GitHub repositry.

Invited Talk for a graduate course in Water Resources System Analysis at UTSA

October 08, 2024

Research Talk, University of Texas at San Antonio, San Antonio, Texas

I was invited by Dr. Giacomoni to give a class on the topic of 1D hydrodynamic simulations. I showcased the full derivation of the governing equations and presented several example applications of HydroHP-1D to solve engineering problems such as optimizing channel design, evaluating flood propagation in channels, and assessing the effects of dam breaks. The slides and classes are available in the repository of HydroHP-1D.

The Conference on Computational Methods on Water Resources (CMWR)

October 01, 2024

Conference proceedings talk, Conference , Tucson, Arizona

At CMWR, I had a poster and an oral presentation.

  • Identifying the state dependence of effective material properties in a simplified hydrologic hillslope model. In this poster presentation, we showed a calibrated hillslope 1D Richards, 2D Boussinesq model to simulate subsurface hydrological processes in LEO compared to a data assimilation technique.
  • Large Scale Fully-Distributed Hydrologic-Hydrodynamic Modeling: Developing an Early-Warning Tool. In this presentation, we show the current advances we have in the development of an open-source, freely available early-warning tool for large-scale hydrology we are developing.

Tutorial of HydroPol2D with USP Graduate Students

September 01, 2023

Tutorial, USP - Hydraulics and Sanitation Engineering, Sao Carlos, Sao Paulo, Brazil

A 3-day course of HydroPol2D fully distributed hydrologic-hydrodynamic modeling. In this course we:

  • Delineated catchments and obtained all rasters and GIS files to run HydroPol2D
  • Explained details and particularities of the model
  • Showed the open-source code and explained how to adapt the model to the user needs
  • Illustrated the input data procedure
  • Applied the model for different types of rain-on-the-grid boundary conditions

Invited Talk for a Hydraulic Course using UFC system in USP - Sao Carlos

April 01, 2023

Research Talk, UFC Hydraulic System Course, Sao Carlos, Sao Paulo, Brazil

I was invited to present the current advances in hydrologic-hydrodynamic modeling from my Ph.D. In this presentation, I showed early versions of HydroHP-1D and HydroPol2D applications, illustrating applications in the Amazon basin and in urban catchments.

Invited Class Presentation for Civil Engineering undergraduate course at Vanderbilt University

November 29, 2022

Undergraduate Class, Vanderbilt University, Nashville, Tennesse

I was invited by Dr. Taha to present two classes for the Vanderbilt Civil Engineering undergraduate course to talk about the RTC-Stormwater model, a real-time control model of catchments, reservoirs, and channels. We derived the models and showcased some applications for estimating hydrological and hydrodynamic processes.

Latin American Hydraulic Congress

November 01, 2022

Conference proceedings talk, IAHS, Foz do Iguaçu, Paraná, Brazil

I presented two conference papers about applications of HydroHP-1D for varied cases, such as modeling of backwater effects, design of channels, complex boundary conditions, and dam-break scenarios. One of the papers was elected the best one in its category.

  • A Serious Game for societal risk perception of dam-break flood assessment using a hydrodynamic model
  • Assessing the role of cross-section shape for flood routing under compound flood events using a hydrodynamic model

World Environmental and Water Resources Congress

June 01, 2021

Conference proceedings talk, World Environmental and Water Resources Congress, 2021, Las Vegas, Nevada (Online)

Two conference proceedings articles were presented:

  • Permeable pavement hydrological model to assess the long-term efficiency of maintenance using high-resolution temperature and rainfall data
  • Spatial Assessment of Overland Flow, Pollutant Concentration, and First Flush Using a 2D Non-Point Source Pollution and Hydrological Model for Urban Catchments

Brazilian Symposium of Water Resources

December 01, 2019

Conference proceedings talk, Associação Brasileira de Recursos Hídricos (ABRH), Foz do Iguaçu, Paraná, Brazil

Presented two conference papers about inverse modeling of an important detention pond reservoir in Sao Paulo - The Pacaembu’s detention pond - and a sensitivity analysis of discharge coefficients of orifices.
