Nature-inspired optimization is an active area of research in the artificial intelligence (AI)
field and has recently been adopted in hydrology for the calibration (training) of both process …

Droughts are one of the most devastating natural disasters. Droughts can co-exist in different
forms (eg meteorological, hydrological, and agricultural) as concurrent droughts. Such …

Temperature rise, associated with global warming, has increased the severity and frequency
of heat waves around the world. Rajasthan and Karnataka are two major states of India and …

This study proposes a novel complex networks-based framework to examine the spatial
propagation of one type of drought to another (concurrent droughts) in a region and the …

Abstract Study region Varahi River originating from the Western Ghats of India. Study focus
We developed a hybrid model that integrates process-based hydrological model (PHM) and …

Trend analysis of rainfall is often carried out in water resources management to understand
its distribution over a given region. The cumulative seasonal and annual rainfall derived …

Since vegetation is closely related to a variety of hydrological factors, the vegetation
condition during a drought is greatly affected by moisture supply or moisture demand from …

The intensity-duration-frequency (IDF) curve is a critical input for designing hydraulic
infrastructure such as stormwater drainage systems. The last few decades have witnessed …

This work reports climate change signals and long-term trend analysis of climate variables,
meteorological drought, and extreme climate indexes over the tropical state of Kerala in …

This study aims to construct the multiple time-scale joint distributions of drought duration and
severity using two-dimensional copulas and compare the drought characteristics in India's …
