A water-table dependent reservoir model to investigate the effect of drought and vascular plant invasion on peatland hydrology.. Journal of Hydrology, Elsevier, 2013, 499, pp.132-139. 10.1016/j.jhydrol.2013 calculating the stored water in effective porosity of the peat from precipitation and evapotranspiration datasets. Calculations conceptualize vascular plant consumption through a crop coefficient. Changes in water storage, located in the effective porosity of the peat, are described through a maximum infiltration rate and a maximum storage capacity. Water discharges take place in runoff and percolation reservoirs. The runoff coefficient is considered to be water table dependent.This model was tested on a peatland that has experienced strong water table fluctuations caused by summer drought and/or by vascular plant water consumption. A water table dependent runoff model appeared to be adequate to describe the water table fluctuations in peatland. From this model, vascular plants were found to increase the crop coefficient and to limit percolation through the peat. The high water table depth in winter was found to change with the year and is related to an equilibrium between slow infiltration in peat versus percolation plus evapotranspiration. In this disturbed peatland, even if overland flows occurred after a drought, the re-saturation of effective porosity was slow with about 30% of air trapped in the porosity 6 months after the drought period.The effects of drought on peat saturation were observed over more than a single hydrological cycle.This can affect the biogeochemical processes controlling the C cycle in peatland.

“…The knowledge about the hydrogeological features of these aquifers greatly improved due to studies for the construction of the main tunnels and tapping works in southern Italy (Celico, 1978(Celico, , 1983. The hydrogeological conceptual models proposed for these aquifers (Aquino, Petrella, Florio, Celico, & Celico, 2015;Celico, 1983;Celico, Celico, De Vita, & Piscopo, 2000;Celico, Petrella, & Celico, 2006;Celico et al, 2010;Fiorillo, 2011;Petrella, Aquino, Fiorillo, & Celico, 2015;Petrella, Capuano, Carcione, & Celico, 2009) identified strong similarities and differences with those of similar aquifers in other zones of the world (Drogue, 1992;Goldscheider & Drew, 2007;Jeannin, 1998;Kiraly, 1975Kiraly, , 2002Klimchouk, 2000;Mangin, 1975;White, 1969White, , 2002.…”

This paper summarizes the results of a study focused on the hydrogeological characterization and recognition of groundwater resources in continental southern Italy, developed under the European INTERREG IIC Programme. The study reconstructed up-to-date scientific knowledge regarding aquifers, groundwater circulation schemes and groundwater resources exploitation in the administrative regions of southern Italy included in the Objective I (Molise, Campania, Basilicata, Puglia and Calabria). In this paper, the methodological approaches applied to synthesize and homogenize bibliographic data collected from the hydrogeological literature and to set a regional hydrogeological mapping are described. Results presented are three hydrogeological maps, 1:300,000 scale, showing hydrogeological units and groundwater flow schemes that are relevant in the regional hydrogeological context, and a brief description of principal types of aquifer and groundwater resources of continental southern Italy.

“…Segmentation of recession curves has been justified by changes in flow regimes (Milanovic, 1976;Baedke and Krothe, 2001), catchment area, and effective porosity of the declining saturated zone (Bonacci, 1993;Fiorillo, 2011).…”

Estimation of Groundwater Mean Residence Time in Unconfined Karst Aquifers Using Recession Curves

A new parsimonious method is proposed to estimate the mean residence time of groundwater emerging at any specific time during recession periods from karst springs. The method is applicable to unconfined karstic aquifers with no-flow boundaries. The only required data are numerous consecutive spring hydrographs involving a wide range of discharge from high to low flow and the relevant precipitation hyetographs. First, a master recession curve is constructed using the matching-strip method. Then, discharge components corresponding to the individual hydrographs at any desired time are estimated by extrapolation of recession curves based on the master curve. Residence times are also taken from the time elapsed since the events' centroids. Finally, the mean residence time is calculated by a discharge-weighted average. The proposed method was evaluated for the Sheshpeer Spring in Iran. There are 259 sinkholes in the catchment area of the Sheshpeer unconfined aquifer, and all the boundaries are physically no-flow. The mean residence time calculated by the proposed method was about one year longer than that of uranine dye tracer. The tracer mean time is representative of flowing water between the injection and emergence points, but the mean time by the proposed method is representative of all active circulating water throughout the entire aquifer. The proposed method is more appropriate, in practice, especially in groundwater recharge and contaminant vulnerability assessments, than isotopic methods, in cases where a small portion of water with exceptionally high residence time increases the mean. Moreover, isotopic methods are more expensive and not capable of directly determining the residence-time distribution.
