They play a crucial role in the socio-economic development of the region. Therefore, the estimation of groundwater recharge is necessary for a good management of water resources, while considering the impacts of climate change. The present study utilizes the application of APLIS method integrated with Geographic Information System (GIS) as a remote sensing technique for geospatial analysis to explore groundwater recharge areas along Khalled-Teboursouk basin, expressed as a percentage of precipitation combined with numerous parameters. The morphology of earth surface features such as Altitude (A), Slope (P), Lithology (L), infiltration (I), and Soil (S) influence the groundwater recharge rate in carbonate aquifers, from the infiltration of rainfall in aquifers in either direct or indirect way. The results revealed that 60–80% of precipitation is identified as high potential for groundwater recharge and it is associated with karstified limestones of Eocene lower age. The gentle slope areas in the Middle-East and Central parts have been moderate potential for groundwater recharge 40–60% of precipitation and they are associated with karstified limestone of Campanian-Maastrichtian age (Abiod Fm.). Hilly terrains with low and very low recharge are the most represented for groundwater recharge processes. They are associated with areas of non-karstified rocks and Quaternary deposits. The dominant water type of the groundwater in this area is Ca–Mg–Cl–SO₄ water type. The Total Dissolved Solids (TDS) of these waters (0.37 to 3.58 g/l) are slow in the recharge area and high in the discharge area. This is caused by rapid circulation of water from the recharge areas to the discharge points. The aquifers have been recharged by rainfall originating from a mixture of Atlantic and Mediterranean vapor masses. The isotope analyses, δ¹⁸O and δ²H ranged from − 6.8 to -5.3‰ (vs. SMOW) and from − 42 to -4‰ (vs. SMOW) respectively, confirm the recent recharge of these carbonate aquifers.</p></div>","PeriodicalId":46286,"journal":{"name":"Applied Geomatics","volume":"16 3","pages":"677 - 693"},"PeriodicalIF":2.3,"publicationDate":"2024-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141653553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The long processing steps needed to generate FAD curves, which involve logarithmic binning and iterative model fitting using various statistical tools, constitutes an energy and time-consuming task that pushes many researchers away from using the technique. In fact, no fully automatic tool capable of generating FAD curves and models exists as of July 2023. Therefore, we attempt to provide a fully automatic computer program capable of binning, fitting FAD curves and assessing their goodness of fit to theoretical models in a fully automatic, one step process. An example is provided using real data from Taounate province, Northern Morocco, so as to demonstrate the ability of the tool to deal with exhaustive datasets. In addition, the Kolmogorov-Smirnov, goodness of fit test is added to provide an objective assessment of the data fitting, which constitutes a better alternative to the subjective visual assessment that most landslides researchers rely on.

The present study aims to study the urban growth patterns of the fast-growing Mumbai Metropolitan Region (MMR) using the Landsat data from 1999 to 2019 and to evaluate the neighbourhood configurations’ effect on urban growth prediction. The urban area maps are classified using a maximum likelihood algorithm and are used along with the potential drivers to test three levels of neighbourhood considerations. The first model assumes no neighbourhood effect, the second incorporates the built-up pixels in the neighbourhood as an additional potential driver variable, and the third uses a Cellular Automata (CA). The CA model explores variations in neighbourhood types and sizes, distance decay and iterations to identify the optimal configuration. The results show an 89.44% increase in built-up areas over two decades (1999-2019). The urban growth prediction model testing reveals the importance of neighbourhood, with the first model without neighbourhood consideration giving the least accuracy (67%) while the inbuilt neighbourhood model gives better results (71%). However, the CA-based model with a 9 × 9 Moore neighbourhood, distance exponent β = 2 and two iterations give the highest accuracy (76%).

However, in this study, a scenario in which the calculated LST for a pixel is not only affected by the factors in the same pixel but also by the factors in the neighbor pixels is studied. Firstly, required maps for the calculated LST and influential factors (indicators of vegetation, building, and water surfaces) are produced from satellite remote sensing images. Secondly, the relationship between the LST and influential factors is modeled using the Ordinary Least Squares (OLS) model. Thirdly, Moran’s I and Lagrange Multiplier tests are used to analyze the existence of spatial dependency and correlation in residuals of the OLS model. Fourthly, three spatial regression models (Spatially Lagged X (SLX), Spatial Lag (SL), and Spatial Error (SE) models) are used to model the spatial dependency and correlation between the LST and influential factors. Finally, the outcomes of the models are compared and evaluated. Results present related maps for the variables besides maps for spatial residuals in the spatial regression models. The outcomes of the models are investigated by p-values, log-likelihood, and RMSE.

Information on rice production is thus essential for agricultural management and the formulation of food security policies. The objective of this research is to develop an approach combining remote sensing and artificial intelligence (AI) techniques with a crop growth model for enhancing yield estimation and crop management in Taiwan. The data processing involves three main steps: (1) data pre-processing to generate model inputs, (2) crop yield modeling through assimilating satellite-derived leaf area index (LAI) into a crop growth model using the AI particle swarm optimization (PSO) algorithm, and (3) model validation. The assimilation process was performed using a cost function based on the difference between remotely-sensed and simulated LAI values. The optimization process began with an initial parameterization and appropriately adjusted input parameters in the model. The fitness value derived from a cost function was determined using the PSO. The results of yield estimates obtained from the crop growth model based on optimized inputs were evaluated using the government’s yield statistics, revealing close agreement between these two datasets. The root mean square percentage error (RMSPE) and the mean absolute percentage error (MAPE) for the first crop were 19.8% and 17.1%, and the values for the second crop were 8.4% and 6.3%, respectively.

Likewise, to establish the degree of performance of each parameter, different control points have been established. We then trained and tested our DL models using the receiver-operating characteristic-area under curve (ROC-AUC) and precision-recall plots.
