The Role of Global Data Sets for Riverine Flood Risk Management at National Scales

Water Resources Research, Volume 58, Issue 4, April 2022., 2022
Abstract Over the last two decades, several data sets have been developed to assess flood risk at the global scale. In recent years, some of these data sets have become detailed enough to be informative at national scales. The use of these data sets nationally could have enormous benefits in areas lacking existing flood risk information and allow ...

Predicting maximum force in SPIF for different materials

Matéria (Rio de Janeiro), 2022
Abstract Knowing the importance of predicting acting forces during the formation process, our research has conducted 27 SPIF experiments in hyperboloid format, followed by Finite Element Method (FEM) simulations to validate the measurements found in order to determine regression equations to estimate maximum axial force in the SPIF process ...
