“…Exceptional meteorological drought occurs in 1994-1995 and 1999-2000, but in some years severe to extreme drought occurs mainly from 1995 to 1996 and 2000 to 2003. The patterns of the SPI cycle generally agree with those of MSDIc, displaying that SPI derived from rain gauges can detect severe drought episodes (De Jesús et al 2016;Kavianpour et al 2020).…”

“…It seems that in some years there is a relation between MSDIc/SPI and groundwater depth in the study area (Figure 9; Kavianpour et al 2020). The exceptional meteorological drought in 1994 corresponds to an increase in groundwater depth in the consequent year of 1995.…”

“…In a recent study focused on identifying the influencing factors on groundwater drought and depletion in north-western Bangladesh, it was shown that there is a vital need of including human-induced effects for drought analysis, and a latent urgency for new research and methods to identify the human influence on groundwater depletion (Mustafa et al 2017). Several studies have improved the general understanding of how a groundwater system may respond to human influences, as well as on the potential impacts on groundwater drought (Parkinson et al 2016;Jakóbczyk-Karpierz et al 2017;Thomas et al 2017;Han et al 2019;Escriva-Bou et al 2020;Kavianpour et al 2020;Persaud et al 2020).…”

Groundwater is the main source of water in arid cities where precipitations are low and not evenly distributed. The combined impact of climate variability and intensive human activities has caused a substantial decline in groundwater levels. Understanding the response of groundwater levels to meteorological and anthropogenic factors is a key step to propose water management alternatives. Meteorological and groundwater data were used to design a multi-step approach to assess the influential factors on the groundwater system in the City of Chihuahua, Mexico. The analysis of historical groundwater levels and climate showed a clear increase in meteorological drought, as well as a groundwater abstraction trend since 1986. Rainfall, groundwater recharge, and groundwater level displayed a significant decrease. Overall, the groundwater depth is continuously increasing with a strong correlation with groundwater abstraction. Despite having a significant trend, the changes in land-cover, groundwater recharge, and meteorological drought were not the main factors inducing the decreased level of water in the aquifer. The continuous abstraction of groundwater from 1986 to 2010 has led to a depletion of groundwater levels from 32 to 92 m. The findings of this study lay a foundation for future water resource management in the study area.

“…As a result, the use of SGI to assess groundwater drought has grown. Pathak et al (2016) (Harisuseno, 2020;Kavianpour et al, 2020). Based on a quantitative assessment of groundwater drought conditions, some scholars have begun to identify the characteristics of groundwater drought.…”

The urban groundwater system is complex and affected by the interaction of natural and human factors. Groundwater scarcity can no longer reflect this complex situation, and the concept of groundwater drought can better interpret this situation. The groundwater drought cycle is the time interval in which groundwater droughts occur repeatedly and twice in a row. The study of the groundwater drought cycle can more comprehensively grasp the development characteristics of the groundwater drought, which is of great importance for the development, utilization, and protection of groundwater. This study used monthly observation data from seven groundwater wells in Xuchang, China, in the period 1980–2018. We applied the Kolmogorov–Smirnov test to select the best fitting distribution function and constructed a Standardized Groundwater Index (SGI). We analyzed groundwater drought at different time scales and used Morlet’s continuous complex wavelet transform to analyze the groundwater drought cycles. The following results were obtained: 1) the maximum intensity of groundwater drought in the seven observation wells ranged from 104.40 to 187.10. Well-3# has the most severe groundwater drought; 2) the drought years of well-5# were concentrated in 1984–1987 and 2003–2012 and those in the other wells in 1994–1999 and 2014–2018; and 3) the groundwater drought cycles in the seven observation wells were 97–120 months, and the average period is about 110 months. The cycle length had the following order: well-7# > well-4# > well-5# > well-2# > well-1# > well-3# > well-6. Therefore, Morlet wavelet transform analysis can be used to study the groundwater drought cycles and can be more intuitive in understanding the development of regional groundwater droughts. In addition, through the study of the Xuchang groundwater drought and its cycle, the groundwater drought in Xuchang city has been revealed, which can help local relevant departments to provide technical support and a scientific basis for the development, utilization, and protection of groundwater in the region.

“…This reflects that climate change has led to myriad problems in all aspects of human life. Climate change hitherto has been observed in many parts of the world, and Iran, with an arid and semi-arid climate, has experienced significant climate anomalies due to such a change (Alizadeh-Choobari and Najafi 2018; Kavianpour et al 2020). Drought is a phenomenon with severity and highly sensitive to climate change return period.…”

This study puts forward a novel approach to identify Parishan Lake drying up roots by studying the dynamic evolutions in the study sub-basin. SPI, extreme climate indices, and several parameters (precipitation, evaporation, and temperature) were employed for 16 years (2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017)(2018). To obtain the object of the study, the phase space reconstruction method of delays and chaos theory were applied. Reconstruction of the phase space exposed that some attractors were elliptical shape and some were point. The temperature, evaporation, TXn, and PET suggested periodic time-series. However, TX90p, TX10p, TN10p, and SPI revealed aperiodic time-series, and, RX1day, Rx5day, and precipitation exhibited quasi-periodic behavior in time-series. The trajectory dispersion of all the parameters except TN10p, TX90p, and SPI reflected low chaos, while TN10p, TX90p, and SPI presented random behavior. The phase space behavior of RX1day, Rx5day, TN10p, precipitation, TX90p, and TX10p was nonsinusoidal. By contrast, temperature, evaporation, TXn, PET, and SPI displayed sinusoidal phase space behavior. The findings confirmed that Parishan Lake sub-basin has experienced climate changes which have generated anomalies in climatic and nonclimatic parameters. The comparison between reconstructed phase space of study sub-basin and control sub-basin verified that climate change yielded equal impacts on the study and control sub-basins. As it was highly improbable that the Parishan Lake could be dried up in less than 10 years due to climate change, other affecting factors were also addressed. The findings indicated that excessive groundwater exploitation (as the key factor) increased dryness in the Parishan Lake sub-basin.
