Abstract: Apart from creating an ecological imbalance, drought events could affect an agrarian country's economy and food security by reducing crop yields. The antecedent meteorological droughts could prolong into hydrological and (or) agricultural droughts and may…

Abstract: Modeling and understanding the statistical relationships between geophysical quantities is a crucial prerequisite for many geodetic applications. While these relationships can depend on multiple variables and their interactions, commonly used scalar methods like the (cross)…

Abstract: Floods are disastrous events in nature. In order to minimize the loss caused by these inevitable events, there is a need to estimate the risk of their occurrences. Several attempts have been made to study…

DOI: 10.1016/j.energy.2020.117063
Abstract: Water and energy are closely linked and restrict each other, which has become major restraints to urban development associated with constricted water resources availability, increased electricity demand and limited environmental capacity. In this study, a…

DOI: 10.1016/j.physa.2019.04.077
Abstract: In this paper, we deal with the evaluation of Conditional Value-at-Risk in the framework of portfolio theory by using a modified Gaussian Copula – where the modification is obtained by introducing the Generalized Correlation Coefficient…

Abstract: Abstract The recent increase in population growth and urbanisation demands for real-time riverine water management to fulfil the daily-scale domestic and ecological water needs, necessitating for high-frequent streamflow estimation at any river section. Although there…

Abstract: ABSTRACT This study examines the extent of systemic risk embedded in the credit and equity markets using a conditional value-at-risk (CoVaR) measure. We implement a copula-based CoVaR approach with different perspectives of a dependence structure…

Abstract: The joint analysis of spatial and temporal processes poses computational challenges due to the data's high dimensionality. Furthermore, such data are commonly non-Gaussian. In this paper, we introduce a copula-based spatiotemporal model for analyzing spatiotemporal…
