The upstream part of the Essaouira basin, a data-scare region in Morocco, Northwestern Africa. scarcity hydro-climate data is significant challenge found several regions worldwide, where qualitative and quantitative water resource information remains limited. Estimating predicting groundwater levels (GWL) such areas producing knowledge for effective management. To address this issue, present study aimed to use Soil Water Assessment Tool (SWAT) model conjunction with downscaled total storage (TWS) (9 km) obtained from Gravity Recovery And Climate Experiment (GRACE) machine learning techniques, specifically random forest (RF) support vector (SVM), estimate predict variation GWL. This constitutes first its kind area; SWAT was set up 10 years, warm-up period 2000 2001, calibration 2002 2007, validation 2008 2010. statistical indices (Coefficient Determination (R²) ≥ 0.73, R² 0.78, Nash–Sutcliffe efficiency coefficient (NSE) 0.67, NSE 0.80 respectively validation) highlight correlation, implying model's capability faithfully reproduce streamflow. TWS demonstrates an impressive ability identify monitor fluctuations Using algorithms (RF SVR), prediction GWL yielded satisfactory results, = 0.78 root mean square error (RMSE) 0.33, 0.51 RMSE 0.49 RF SVR, respectively. Despite some limitations, our approach provided promising results prediction, possibility expanding other data-scarce regions.

The Atlas Mountains of Morocco, specifically the High Oum Er-rbiaa (HOER) and Ourika catchments. to identify recharge processes within semi-arid watersheds, in Mountains, through monthly monitoring snow, rainfall, surface water, groundwater isotope signal, but also usage remote sensing data. spatial-temporal analysis precipitation isotopes reveals significant spatial heterogeneity, primarily influenced by geological variations each aquifer. Temporal indicate that direct occurs response winter precipitation, whereas a delayed is observed during summer when snow replenishes towards end melting season. findings are further supported "Gravity Recovery Climate Experiment" (GRACE) dataset, which demonstrates high values Total Water Storage (TWS) align with isotopes. This highlights substantial abstraction rate between March June compensate for lack this period. data indicates 50% upstream Jurassic aquifer 80% downstream Triassic-Paleozoic aquifers HOER catchment sourced from snowmelt. Similarly, catchment, snowmelt contributes 30% portions catchments respectively. disparity due different rates across altitudinal ranges lithology catchment.

Salinity-Induced Changes in Heavy Metal Behavior and Mobility in Semi-Arid Coastal Aquifers: A Comprehensive Review

Water, Год журнала: 2024, Номер 16(7), С. 1052 - 1052

Semi-arid coastal aquifers face critical challenges characterized by lower rainfall, higher evaporation rates, and looming risk of over-exploitation. These conditions, coupled with climate change, are conducive to seawater intrusion promote mechanisms associated it. The understanding metal behavior in such environments is limited, hence, an attempt made through this review bridge the knowledge gap. A study on trace metals within a specific context semi-arid was carried out, 11 from 6 different countries were included. observed that exhibit distinctive behaviors influenced their surrounding environment. prevalence continuous played pivotal role shaping dynamics curtailing groundwater flux. findings suggest formation stable Cl organic ligands under increased alkaline conditions (pH > 8) has control over Zn, Pb, Cd toxicity highly ionic reactive condition.

On contrary, prevailing acidic < 6), carbonate SO4-ligands become more dominant, bioavailability/desorption Cu irrespective origin. Ni found be controlled increasing salinity.

Understanding the trade-offs between climate change-induced aridity and agricultural water demand in the Souss basin, Morocco

Frontiers in Water, Год журнала: 2024, Номер 6

The concept of integrated water resource management requires an in-depth analysis inflows into a river basin. Population growth and the uncertainties associated with climate change are causing increased stress droughts, which impacting agriculture. Hence need for studies on impact demand-supply interactions in basins. In this study, generic decision support system, ModSim, was used; first time region; to examine agricultural usage demands over Souss basin Morocco. ModSim calibrated period from 1990 2019 using recorded data about physical processes hydraulic infrastructures features management. simulations succeeded replicating different deficit episodes at various irrigated perimeters. During simulated 2012 2019, it observed that supplies dams experienced decline ranging 38% 89%. As result, average total unmet demand surface reservoirs areas reached 201 mm 3 between monthly increases by 55% dry season, compared rest year. significant amount across all sites suggests satisfied withdrawal groundwater resources. adopted approach has proven be useful tool understand resources planning challenges. Water managers require such reliable tools represent basin's trade-offs. Thus, additional investigation improve representation groundwater/surface interaction approaches is required enhance evaluation consequences uses, especially arid semi-arid regions as Souss. A conceptual framework well detailed discussion have been produced order guide efficient governance.
