Impact of Climate Change on River Discharge and Groundwater Level Using Copula Functions (Case Study: Siminehrood River Basin, Iran) [PDF]

Water Harvesting Research
The aim of this research is to simulate and predict the groundwater level in the Siminehrood River Basin, which is situated south of Lake Urmia, Iran. This simulation was conducted using copula functions while accounting for changes in river discharge ...

Copula-Based Bayesian Inference Approaches for Uncertainty Quantification for Hydrological Simulation

Hydrology
In this study, an advanced copula-based Bayesian inference framework is proposed to characterize probabilistic features in hydrological simulations. Specifically, a Copula–Metropolis–Hastings (CopMH) algorithm is developed through integrating copula ...

A Copula-Based Scenario Generation Method for Renewable Wind Power Outputs of Two Wind Farms

Energies
Renewable wind power output is characterized by strong randomness, volatility, and spatial dependence, which makes accurate two-adjacent wind farm scenario generation essential for stochastic dispatch and secure operation of power systems.

On the Distortion of a Copula and its Margins [PDF]

This article examines the notion of distortion of copulas, a natural extension of distortion within the univariate framework. We study three approaches to this extension: (1) distortion of the margins alone while keeping the original copula structure, (2)

Aggregation functions: an approach using copulae [PDF]

In this paper we present the extension of the copula approach to aggregation functions. In fact we want to focus on a class of aggregation functions and present them in the multilinear form with marginal copulae. Moreover, we define the joint aggregation
