“…Based on the results and the analysis of the SPI index, the surveyed area was categorized as experiencing normal drought conditions. These ndings align with previous studies by [30], [39], and [24]. Climate classi cation results from three synoptic stations in the region indicated that the area falls within the semi-arid climatic category.…”

Groundwater reservoirs are acknowledged as a vital and cost-effective water source, and comprehending their significance and efficient utilization can foster sustainable development of social and economic activities in a region, particularly in arid and semi-arid regions. This study aimed to explore the correlation between the GRI index and standard rainfall, followed by the classification of the region's climate using the De Martonne method. The research focused on analyzing the temporal variations in recent droughts and climate classification concerning underground water resources in the Qorveh-Dehgolan plain. The GRI calculation method was employed to assess groundwater depletion over periods ranging from 1 to 48 months in the Qorveh-Dehgolan plain. Additionally, ArcGIS software was utilized to zone the groundwater levels and drought severity. The study conducted a correlation analysis between GRI and SPI indicators through linear regression in Excel, revealing a lack of significant correlation between the two indicators (P-value = 0.053 and R2 value = 0.003), despite their distinctiveness. Furthermore, the drought classification based on SPI indicated that the region fell into the normal drought category. The climatic classification derived from three nearby stations was established as semi-arid using the De Martonne method.

Due to overcapacity, the current airport of Yogyakarta is going to be replaced with a new one, which is located in Wates coastal area, Kulon Progo District, Yogyakarta Special Province, Indonesia. One of the consequences of the development of the new airport is groundwater abstraction due to the airport's needs and related supporting activities. An excessive withdrawal of groundwater in the new airport will potentially change the system and the pattern of groundwater flow. Therefore, groundwater modeling should be done to predict the impact of groundwater abstraction in this area. MODFLOW code is used to simulate the groundwater flow and the impact of groundwater pumping in the Wates coastal aquifer. The model is calibrated using water level data from 40 wells in the research area. The results show that the calculated values are fit to the measured data, which indicates that the model is reliable. The effects of groundwater pumping on water table and seawater intrusion are investigated using a calibrated model. The results show that the pumping scenario from the airport area causes the groundwater level to drop 0.75 m and seawater intrusion inland to increase around 100 m.

“…The GRI index can explain groundwater drought properly. In some previous researches, such as Nayak et al, [56] the drought indices were only based on a normalization method. In their study they provided the precipitation data and groundwater level data for a catchment which had 541 wells.…”

The effect of meteorological and hydrological droughts is very important in arid and semi-arid regions. Analyzing these effects on groundwater supplies plays an important role for water management in those regions. This paper aims to characterize droughts in the Isfahan-Borkhar basin, an arid area of Iran. The observed hydro-climatic data (for the period of 1971-2005) were used for hydro-meteorological projections (for the period of 2006-2040). Meteorological and surface hydrological drought evaluated by Standardized Precipitation Index (SPI), Standardized Runoff Index (SRI), and the effect of hydro-meteorological droughts on groundwater was investigated by Groundwater Resources Index (GRI). Results showed that dry and wet conditions would occur in the region in the initial and subsequent decades, based on the three indices. There was a significant association between SPI, SRI, and GRI at the time scale of 12 months. The SPI estimated using only meteorological variables alone and it is useful for estimating meteorological drought forecasts. However, SRI and GRI can represent hydrological drought that computed using catchment discharge, soil moisture and groundwater level. Results showed a considerable alteration in time of drought outlines across the area and association between the variables of predicted precipitation, temperature and the kind of indices. The projection of all three drought indices indicated drier conditions in the future period (2006-2042). The results provide reasonable management strategy for management of water resources in arid coastal plains.
