AbstractThis chapter presents the foundations of dendrohydrology as employed in the ARCHIVES project. The development of annual rings in trees subject to seasonality is dependent on physiological processes leading to changes in the physical, biological and chemical properties of woody tissues. The rings formed, by their width, density and isotopic ratios of their elements (oxygen and carbon) provide information on the tree growth conditions. The metabolic processes leading to the production of woody tissue (wood) are governed by so-called limiting factors that dendrochronology seeks to reconstitute. The application of dendrochronology to hydrology (dendrohydrology) is supported by three approaches: 1) the search for indicators of the stresses caused by excess or lack of soil water for growth, 2) the dating of the direct actions of water or ice on trees bordering water bodies, and 3) the study of concordances between the hydro-climatic variations of a region (precipitation and temperature) and the characteristics of the rings of affected trees. The ARCHIVES project consisted in exploring these avenues over a vast territory in northern Quebec-Labrador.
