Our analysis highlights the interest of combining hydraulic and age information for the prediction of residence time distributions within full hydrogeological models, and the capacity of identifying global hydrogeological structures from point-like data.
The hydraulic method suggests ages in the order of 3000 years (between 1500 and 7000 years) for the A1 CAS system and in the order of 4000 years (between 2000 and 9000 years) for deeper systems (A2a and A2b CASs).
The responses of water flux to D varied among species, size or age, and hydraulic architecture, which highlights that modeling water budget to land cover transition based on the same hydraulic parameter from one land use scenario can potentially cause extensive errors in model prediction.
Isotopic (18O, 2H, 3H, 13C and 14C) and geochemical studies (Cl SO4 HCO3 and Na K Mg ternary diagrams) were made to evaluate groundwater age and hydraulic and geochemical features of the aquifer system.
The examination of the technological level in (monumental) constructions and hydraulic works of Middle Bronze Age – Late Bronze Age (MBA, ca. 2200/2100-1580 B.C. – LBA, ca. 1600 110000 B.C). Greece, and the environment that was shaped, as it is implied by the material evidence, could infer implications for the historical canvas of the period.
Undisturbed samples were collected at 3 depths: 0 10 cm, 10 25 cm and 25 40 cm, from permanent grassland, aged 1, 8 and 19-years, and were used to determine water retention and saturated hydraulic conductivity for each sward age.
Equilibrium modulus decreased significantly with increasing donor age (P<0.01) while hydraulic permeability increased significantly (P<0.02).
Slackwater deposits, archaeological age dating and hydraulic modelling allowed us to reconstruct some of the oldest extreme floods reported in Spain.
Factors that affect SDI uniformity are emitter clogging, root intrusion, root pinching, mechanical and pest damage, soil overburden and compaction, soil hydraulic parameters, and, possibly, system age.
In the Financial Times, Martin Wolf, hardly a man to lose himself in euphoria, examines the promise of hydraulic fracking and "a golden age of gas".
