“…Therefore, these analytical solutions apply in principle only to specific cases (uniform flow, infinite or semi-infinite medium, low heterogeneity in particular). Their validation, therefore, requires recourse to in situ experiments (for example [27]) or to numerical simulations [6,[28][29][30][31][32][33]. The results of these different works show that these solutions can be applied to cases where the spatial variability of 𝐾ℎ is low.…”

It is accepted that digital models simplify the physical reality that is the object of the modeling. Hydrodynamic modeling is an approach with high uncertainties in this context. Indeed, the deterministic modeling approach assumes the existence of a functional relationship between the observed variables. The variables are observed by a series of measurements riddled with errors. Because of this, there is always a significant amount of uncertainty associated with a hydrogeological model. This uncertainty can be associated with the conceptual model or with the data and parameters associated with the different components of the model. Some model parameters such as hydraulic conductivity and recharge are particularly susceptible to uncertainty. Stochastic modeling of the hydrodynamics of a groundwater reservoir is an adequate response to allow us to take a step back on the significance of the results. The study is based on the development of a direct problem-solving model which represents the best estimate of the real hydrodynamic system. This model is used to make predictions. With a stochastic approach, a set of models is constructed where each model, as a whole, is considered to be equally likely. Each model is then used to make the prediction or simulate a given scenario. The MODFLOW-STOCHASTIC-GMS code allows us to do randomization simulations (Latin Hypercube method) and with parameter indicators.

“…Taking into account the specificities of each region and territory, water managers and water users adopt specific methods that are sometimes adapted to the local contexts (Akhmadiyeva and Abdullaev, 2019;El Mezouary et al, 2020b). In this way, the integrated water resources management (IWRM) framework has been widely used as management approach that takes into consideration economic, environmental, and social aspects all combined (Collins et al, 2020;Giordano and Shah, 2014;Lenton, 2011;Schröder, 2019).…”

This article aims to understand the typologies of stakeholders, their role in the water resources management system in the R’Dom Sub-basin(Morocco), and to identify the current and desired interactions among stakeholders. For this purpose, The MACTOR participatory approach was adopted to involve all key water stakeholders and to analyze their interactions. The action system was characterized by the analysis of related issues and relevant actors on the ground. Thus, ten actors and twelve objectives were identified and assessed in this study. The analysis of stakeholder games allowed to identify the typologies of stakeholders according to their strategic objectives and to evaluate their power, influence and dependence, as well as their convergence in a global water management system. The results show a significant level of convergence among stakeholders despite the existence of certain stakeholders who may be considered autonomous given their low involvement in integrated water management. Furthermore, there was a limited involvement of stakeholders in certain strategic objectives such as capacity building, technical means, and awareness-raising actions. The paper shows the need to generate greater collaborative efforts among water stakeholders involved in the implementation of integrated water resources management in the R'Dom sub-basin.

“…Infiltration basins are a good management tool for rainwater and treated wastewater. Widely used today as an alternative to the sewerage network of stormwater, which reduces the risk of flooding, contributes to the trapping of pollutants, and allows the settling of suspended matter loaded with pollutants [1][2][3]. Infiltration basins are also known to recharge the groundwater as well as other benefits [4][5][6][7].…”

The clogging of infiltration basins is the main problem affecting the proper functioning of groundwater artificial recharge systems. In this study, several parameters have been varied to understand their impacts on water infiltration. The experimental results show that the effect of initial humidity is significant for less porous material such as silty soil (Hamri) and sand. The air bubbles are also an important factor to take into consideration since when trapped within porous structures, it forms a barrier for the displacement of water infiltration. The accumulation of suspended particles in stormwater can contribute to clogging by creating a light layer due to the finest particles, which remain in suspension for a long time. Finally, for the tested materials and experimental conditions, we observed that a combination of a silty soil and sand layer in the design of infiltration basins was more practical than a combination of sand and gravel. The latter, despite its high porosity, could release very fine particles; which would create a cement layer of clogging when deposited at the interface. This layer is an obstacle for water infiltration, thus rendering the device thus constructed unsuitably for groundwater recharge, by reducing its life.
