Carbon (C) modeling and carbon dioxide (CO2) flux measurements in peatlands are dependent on the distribution and productivity of vegetation in a system with a high degree of spatial variability, often linked to the position of the water table. We tested the hypothesis that at a fine-scale (tens of metres) water table position exerts a strong control on species abundance, plant biomass, particu...

The coastal aquifers of the Mediterranean region are highly susceptible to seawater intrusion due a combination challenges such as land subsidence, high aquifer permeability, urbanization, drainage, and an unsustainable use water during dry summer months. present study is focused on statistical analysis groundwater data evaluate spatial changes level electrical conductivity in phreatic Emilia-R...

A freshwater lens underlain by saltwater exists beneath the entire northern Yucatan karst plain, Mexico. Water levels recorded in this plain, during the period June 1987 April, 1989, were used to map the water table, identify inland hydrogeologic boundaries, and estimate the thickness of the freshwater lens using the Ghyben-Herzberg relation. The water table under most of northwestern Yucatan i...

Coastal aquifers are highly dynamic groundwater systems. Sea level rise will cause a in coastal tables resulting increased risk of shallow or emergent (Befus et al., 2020). Marine water fluctuations the beach table to oscillate over relatively large range. Understanding these oscillations is crucial, as (i.e., high) may impact subsurface infrastructure, mobilize sediment, and increase liquefact...

Abstract Background: Nowadays, with population growth and the increase of water demand in different sectors of agriculture, industry, drinking, and health, groundwater resources have faced a lot of pressure. This issue along with severe and prolonged droughts has created the conditions for country particularly for arid and hyper arid areas which has encountered the serious challenges in the ...
