Palestras e apresentações

I presented an overview of my research trajectory in flood and water-quality modeling, dam-break simulation, and open-source hydrologic-hydrodynamic model development. The talk discussed lessons from building numerical tools from scratch, including HydroPol2D, HydroHP-1D, and related research codes developed during my Ph.D. at the University of Sao Paulo.

I gave an invited talk on my Water Resources Research paper about identifying state-dependent effective material properties in simplified hydrologic hillslope models. The presentation focused on the Landscape Evolution Observatory (LEO), how simplified hillslope models can represent effective soil properties, and why these properties may change with hydrologic state.

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.

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.

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.

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.

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

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.

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.

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

I presented two conference papers available here and here.

I presented a conference TC-Hydro model application for bioretention system analysis.

I presented the conference paper available here.

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

I presented one of the earliest versions of HydroPol2D, showcasing applications of the model to simulate river routing and pluvial flood routing.

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.
