“…In simpler terms, by having knowledge of only the marginal distributions of two random variables, it is theoretically possible to construct their joint distribution. Copulas have found widespread application in various fields, notably in finance [13][14][15][16][17] and hydrology [18][19][20][21][22][4][5].…”

“…Musafer et al [29] proposed a method utilizing vine copulas to estimate prediction uncertainty within an environmental context. Pereira et al [30] employed vine copulas to achieve a stochastic simulation of stream-flow scenarios.In a more recent development, El Hannoun et al [4] utilized R-vine copulas to model the co-dependencies of five reservoirs, emphasizing hydrologic design and cascade reservoir management in the basin of the Saint-John River. This research highlights the versatility and applicability of vine copulas in addressing various aspects of hydrological studies, ranging from temperature relationships to storm variables, prediction uncertainty, stream-flow scenarios, and reservoir co-dependencies.…”

“…This paper introduces a hydro-economic optimization model that explicitly accounts for climatic uncertainties. The problem is framed as a chance-constrained program, where the dependence structure between hydrologic and meteorologic variables is modeled using copulas theory [4,5]. This innovative approach aims to provide a robust framework for managing water resources by incorporating and addressing the inherent uncertainties associated with climate change impacts on hydrology and meteorology.…”

Climate change significantly affects water resources through alterations in rainfall patterns, reduced rainfall quantities, rising temperatures, and prolonged drought cycles. Consequently, the escalating demand for water coupled with diminishing water availability is anticipated to lead to a critical water scarcity issue in the future unless proactive and innovative strategies are implemented.The impact of climate change on water resources is globally recognized as an increasingly vital concern, given its intricate interconnections with various sectors, notably agriculture, energy, and the provision of drinking water. Consequently, the scientific community has dedicated substantial efforts to devise optimal water resource management strategies in response to the challenges posed by climate change. Over the past four decades, hydro-economic models (HEM) have been instrumental in proposing solutions to adapt to evolving climatic conditions.This paper presents a newhydro-economic optimization model accounting for climatic uncertainties. The problem is formulated as a chance-constrained program in which the dependence structure between hydrologic and meteorologic variables is modeled using copula theory. The novelty of the approach lies in the capacity of the model to optimize the water resources, taking into account the dependence between agronomic, socio-economic, and hydrologic systems and climatic uncertainties.
