Dans la zone semi-aride de Tunisie centrale, un grand barrage a été construit en 1982 sur l'oued Zeroud, dont l'infiltration des crues naturelles constituait jadis la principale source d'alimentation des nappes de la plaine de Kairouan. Ce barrage est destiné à l'écrêtement des crues, l'irrigation et à la recharge des nappes à l'aval de la retenue. Entre 1988 et 1996, plus de 70 millions de m3 d'eau ont été mobilisés sous forme d'ondes de lâchers à partir du barrage pour la recharge artificielle par infiltration dans le lit de l'oued. Le suivi des ondes de lâchers est effectué sur 3 stations de contrôle disposées sur une distance de 40 km le long du lit. L'analyse de l'évolution des débits a révélé que la capacité d'infiltration du lit augmente progressivement avant de se stabiliser, mettant en évidence l'effet de l'air sur le processus de recharge. Un modèle conceptuel à réservoirs conjuguant fonctions de production et de transfert avec discrétisation spatiale a permis de modéliser la propagation et l'infiltration des ondes de lâchers le long de l'oued. Son ajustement sur un échantillon de six événements de lâchers a fourni des résultats satisfaisants. Même si la validation reste insuffisante en raison de la rareté des données, ce modèle peut constituer un premier outil d'évaluation de l'efficacité de la recharge et de prédiction de son impact sur la nappe souterraine de la plaine de Kairouan.

“…The peak of recharge rate occurs at t=6.5 d, which is 1.5 days after the peak of leakage rate. As proposed by Besbes and De Marsily (1984) and Zammouri and Feki (2005), the effect of vadose zone to groundwater recharge can approximately described by a transfer function. For a thick vadose zone, the transfer function of several linear reservoirs can be considered.…”

“…However, the characteristics of infiltration-recharge conversion can be recognized through change of groundwater level as response of leakage events of surface water. In study of the upper river Lys basin and the Origny aquifer with an unsaturated zone (depth of water table is 0-50 m), Besbes and De Marsily (1984) suppose a method in recognizing infiltration-recharge conversion with observed rainfall and groundwater level by using a parametric transfer function. The transfer function method is also applied by Zammouri and Feki (2005) in study of artificial groundwater recharge through leakage from reservoirs on ephemeral streams.…”

Abstract. The behavior of groundwater response to leakage of surface water in the middle reaches area of Heihe River Basin is significantly influenced by a thick vadose zone. The groundwater regime is a result of two recharge events due to leakage of Heihe River and irrigation water with different delay time. A nonlinear leakage model is developed to calculate the monthly leakage of Heihe River in considering changes of streamflow, river stage and agricultural water utilization. Numerical modeling of variable saturated flow is carried out to investigate the general behaviors of leakage-recharge conversion through a thick vadose zone. It is found that the recharge pattern can be approximated by simple reservoir models of leakages under a river and under an irrigation district with different delay-time and recession coefficient.

“…The response function of precipitation represents the passage through the unsaturated zone, followed by a recession curve describing the subsurface drainage of the infiltrated water (e.g., Besbes and de Marsily 1984). A first approximation for the response function of evaporation is the response function of precipitation multiplied by a negative scale factor.…”

A time-series analysis framework for the flood-wave method to estimate groundwater model parameters

The flood-wave method is implemented within the framework of time-series analysis to estimate aquifer parameters for use in a groundwater model. The resulting extended flood-wave method is applicable to situations where groundwater fluctuations are affected significantly by time-varying precipitation and evaporation. Response functions for timeseries analysis are generated with an analytic groundwater model describing stream-aquifer interaction. Analytical response functions play the same role as the well function in a pumping test, which is to translate observed head variations into groundwater model parameters by means of a parsimonious model equation. An important difference as compared to the traditional flood-wave method and pumping tests is that aquifer parameters are inferred from the combined effects of precipitation, evaporation, and stream stage fluctuations. Naturally occurring fluctuations are separated in contributions from different stresses. The proposed method is illustrated with data collected near a lowland river in the Netherlands. Special emphasis is put on the interpretation of the streambed resistance. The resistance of the streambed is the result of stream-line contraction instead of a semi-pervious streambed, which is concluded through comparison with the head loss calculated with an analytical two-dimensional cross-section model.
