\section{Introduction}
\subsection{Study site}
Lake Murten, also known as Lake Morat, is located in Switzerland in the Seeland region (the Three Lakes region), nested between the Alps and the Jura mountains on the Swiss Plateau.
It covers an area of 22.8 km$^{2}$ and possesses a volume of 0.55 km$^{3}$. Its surface altitude is 429 meters above sea level. The catchment area is considered to be 693 km$^{2}$. \\
Historically speaking, this region of the Swiss Plateau is rich in archaeological sites covering the last 10000 years.
%The very first traces of modern humans living in this area date back to 8,000 years before the Common Era (BCE) \cite{international__swiss_wetzikon_nodate}, but more extensive occupation really started around 4300 BCE \cite{bolliger_archaeological_2020, international__swiss_111_nodate, mondial_sites_nodate}. During the Neolithic, the Copper Age and the Bronze Age periods, settlements took the form of pile-dwelling communities on or near lake shores. Three such sites have been studied around Lake Murten, and show that human occupation of this particular area originated around 3500-3800 BCE \cite{international__swiss_greng_nodate, international__swiss_haut_nodate, international__swiss_murten_nodate}. \\
%During the Iron Age, as the population became more dense and centralized, human influence on the environment increased, as shown by the fact that large-scale deforestation and farming became practiced in the catchment area of Lake Murten.\\
%The Romans arrived in the region during the first century BCE. In particular, evidence collected around the modern town of Avenches shows that construction of the Roman city of \it Aventicum\/ began in the first decade CE \cite{blanc_avenches_2004}, and the city reached a peak population of about 20,000 inhabitants during the first century CE \cite{site_et_musee_romains_avenches_aventicum_nodate}.
