“…Vadose Zone Journal considered as a single unit, the geology of such aquifers is, in fact, often highly heterogeneous as the upper units may be crushed or weathered (soft materials), whereas the lower units are generally unaltered and/or fractured (hard materials) (Dar et al, 2017;Williams et al, 2006). The knowledge of water flow and solute transport through limestone aquifers is consequently limited and perceived as especially complex, given the differences in the properties of their geological units (Mosthaf et al, 2018).…”

“…Limestone aquifers have an overriding interest in many countries, especially in the geographic areas under intensive agriculture, as they constitute important drinking water resources but are also vulnerable to groundwater pollutions (Aisopou et al., 2015). Even though limestone aquifers are regularly considered as a single unit, the geology of such aquifers is, in fact, often highly heterogeneous as the upper units may be crushed or weathered (soft materials), whereas the lower units are generally unaltered and/or fractured (hard materials) (Dar et al., 2017; Williams et al., 2006).

Limestone aquifers constitute important drinking water resources but are vulnerable to groundwater contaminations. They are also known to be often heterogeneous. However, the hydraulic properties of their entire vadose zone and the relationship of these hydraulic properties with their mineralogical and geochemical characteristics remain rarely studied. The hydraulic properties of soft (soil, powdery limestone, and calcareous sand) and hard (limestone rock) materials sampled throughout the entire vadose zone profile of the Beauce limestone aquifer (France) were determined with

“…It shows absorptions near 1400 nm and 1900 nm due to the absorptions of water and hydroxyl molecules and at around 2300 nm due to the absorption of Mg-OH and CO 3 molecules that occurred in the minerals of the siltation. The strong absorptions at around 1900 µm are due to the presence of hydroxyl minerals, namely montmorillonite ((Na, Ca) 0, 3 . The absorptions at around 2.3 µm are due to carbonate minerals, namely calcite (CaCO 3 ) and dolomite (CaMgCO 3 ) in the siltation.…”

this study demonstrates the use of ASteR data to map the siltation of the Al-Khod Dam constructed at the lower reaches of Samail catchment area, north Muscat, Sultanate of oman. in this study, the decorrelated image of spectral bands 6, 3, and 1 clearly discriminated the distribution of siltation. The occurrence of siltation is confirmed by the detection of minerals using the VNIR-SWIR bands by the Spectral Angle Mapper (SAM) method. in addition, the siltation of the dam is studied for the years 1987 to 2018 using Landsat satellite images. Interpretation of images showed a gradual increase of the siltation. Mapping accuracy for the occurrence of siltation is assessed by a confusion matrix which produced an overall accuracy of 97.88% and Kappa coefficient of 0.98 in the Maximum Likelihood method. Results of image analyses are verified in the field and confirmed through laboratory analyses. The study of spectral absorption characters of field samples using a Portable Infrared Mineral Analyzer (piMA) showed the presence of oH molecule bearing minerals (clays, serpentines, etc.) and carbonate minerals (calcite and dolomite) in the silt deposits. The occurrence of these minerals is confirmed further by X-ray diffraction (XRD) and Scanning Electron Microscope (SEM) analyses. Groundwater recharge in dams to increase the yield of groundwater for sustainability is very important in arid regions 1. Heavy rainfall and occurrence of flash floods in the regions may deposit large amounts of silts in the dams 2-7. The siltation is a major issue, hindering the infiltration of surface water into groundwater. Increase of such deposits reduce or stop groundwater recharge, decline groundwater levels, and well yields, and deteriorate water quality in and around the dam yearly 5,8. Researchers described the groundwater mounds beneath recharge sites 9-11 and infiltration during erratic floods in karstic basins 12-14. An in-depth study of alluvial stratigraphy provides detail about the number of timing, events, and deposited volumes of floods 15,16. A large number of check dams in the Mediterranean ephemeral streams have been built to prevent sediment inputs 17. Sedimentation rates are studied by infill stratigraphy of check dam and a model is proposed to evaluate erosion and sediment yield processes 18,19. However, meager attempts were made to study the siltations of the dams in Oman. Here the sedimentation in dams is influenced by numerous factors and the dams must be regularly cleaned and dried to continue the rates infiltration and storage capacities 4. In the Sultanate of Oman, many recharge dams across wadis were constructed by the government to hold up runoff and recharge the aquifers. But, most of the dams are silted now due to wadi flow after flash floods in catchments. A suitable technique to map and assess the silt deposits and sedimentation, an alternative to expensive and time-consuming methods 20,21 , is essential and urgently needed by scientists and engineers to remove or protect the deposits of the recharge dams. In thi...
