\section*{Introduction}
This is the \LaTeX template for the full papers of the $4^{\text{th}}$ Pan-American Conference on Unsaturated Soils, June 2025, Ottawa, Canada. Please do not modify the style, format, and structure of this file and only insert your text. For starting a new section, use \verb|\section*{}| command instead of \verb|\section{}|. Including $*$ helps suppressing numbering. The length of the paper should not exceed \textbf{10 pages}, including references.
\section*{Formatting Equations, Figures, and Tables}
Use the following format for your equations, figures, and tables. Equations, figures, and tables should be numbered and appropriately referred to in the text.
\subsection*{Gibbs-Thomson Relation}
The Gibbs-Thomson equation determines the critical pore radius below which the water is at a liquid state and can be described as follows:
\begin{equation}\label{eq:GT}
T_m-T_0=\frac{T_0\gamma_{sl}}{\rho_i\,L_f\,R}
\end{equation}
where $T_m$ is the melting point of water in the pores, $T_0$ is the melting point of pure liquid water, $\gamma_{sl}$ is the free energy coefficient of the ice–water interface, $\rho_i$ is the ice-phase density, $L_f$ is the latent heat of phase transformation, and $R$ is the pore radius~\cite{devoie2022repository}. The variation of freezing temperature with pore radius, as predicted by Eq.~\ref{eq:GT} is shown in Fig.~\ref{fig:GT}. The relation has been used for deriving the freezing characteristics curve, see for instance \cite{zhou2013three}.

\section*{Reference Style}
Please use the ``\verb|unsrt|'' citation and referencing style for your paper. You can simply add your citations to the accompanying ``\verb|refs.bib|'' file provided. Use \verb|@book| and \verb|@techreport| items in the \verb|.bib| file to cite books and reports. Examples of a book~\cite{fredlund1993soil} and a report~\cite{evans1983unsaturated} are given in the reference list.
\section*{Submitting Your Paper}
Please upload the final version of your paper as a single PDF file to the conference webpage at \url{https://www.panam-unsat2025.ca}.
