Rainwater collection and effective water resource management are essential for boosting availability, land productivity, groundwater levels in dry places like Iraq, which is susceptible to climate change drought. This work develops a GIS-based rainfall harvesting (RWH) method the western Karbala Governorate, address shortages future replenishment irrigation demands.

The research found that annual governorate would grow by 18%-24 % 21st century, highlighting necessity of sustainability. Themed RWH layers were created using ArcGIS software multi-criteria decision-making technique. Analytic Hierarchy Process determined tier weights based on seven factors.

Machine learning (ML) algorithms bring about a game changer tool in developing estimation models various fields of research, including water resources and climate change.These techniques can be used for solving problems when assessing change impacts on resources.For instance, they utilized to downscale outputs Global Climate Models (GCMs) investigate effects hydroclimatic variables.Furthermore, ML employed study variations quantity quality under changing climate.Moreover, exploited explore rivers, groundwater, supply systems.Because the importance topic, this special issue intends provide an opportunity collect recent investigations focusing evaluating resources.The scientific peer-reviewed papers contributed are summarized following:• Statistical computation hydrological assessment Understanding how variables over time considering is crucial.Nguyen et al.(2023) evaluated two models, i.e., convolutional neural network (CNN) long short-term memories (LSTM), estimating at 3S River Basin.For impacts, three CMCC-CMS, HadGEM-AO2, MIROC5, scenarios, Representative Concentration Pathways (RCPs) 4.5 8.5, were considered future periods.An increase mean annual temperature fluctuations precipitation detected.Furthermore, ML-based projections yield rise streamflow Srepok Sesan Rivers, reducing trend Sekong, increasing flood risk Sekong basins.Patel & Mehta (2023) conducted statistical analysis Hanumangarh district.They (i) graphical (Innovative Trend Analysis method) (ii) (Mann-Kendall's test Sen's Slope estimator) methods monthly, seasonal, 122 years.Their results indicated southwest monsoon season based method, which was identified as most robust model their study.
