“…The infiltration-recharge process was addressed by several researchers through analytical and numerical approaches (Abdulrazzak & Morel-Seytoux, 1983;Besbes et al, 1978;Flug et al, 1980;Freyberg, 1983;Morel-Seytoux et al, 1990;Moench & Kisiel, 1970;Parissopoulos & Wheater, 1991;and Guzman et al, 1989). Field investigations were carried out by Sophocleous & Perry (1985), Steenhuis et al (1985), Stephen & Knowlton (1986) and Crerar et al (1988).…”

Groundwater recharge in arid regions is intermittent and usually occurs as a result of flood flow transmission losses in dry wadi channels. Hydrograph characteristics play a dominant role in determining the amount of channel abstraction in relation to the width of the wetted perimeter and the time of inundation, and the subsequent groundwater recharge. Large variations in the magnitude of channel losses result mainly from the diversity in inflow volumes. The magnitude of groundwater recharge in relation to bed transmission losses is dependent on flood volume and duration, soil moisture content and physical soil profile characteristics. Runoff volume and duration are the dominant factors influencing the cumulative infiltrated volume and recharge to shallow water tables. Taking into consideration the influence of various hydrological and channel characteristics, several regression equations are suggested to estimate the transmission losses from a wadi bed and the groundwater recharge. Le recharge des nappes par l'infiltration des lits des ouadis dans les régions aridesRésumé L'alimentation des nappes phréatiques dans les régions arides est intermittent et résulte, en principe, des pertes de transmission des eaux des crues dans les lits desséchés des ouadis. Les caractéristiques hydrographiques telle que la largeur du périmètre humidifie et la durée de submersion jouent un rôle principal dans la détermination du volume d'eau qui alimente la nappe phréatique. Les variations importantes dans l'importance des pertes en eau des crues résultent en grande partie, des variations de débit à l'amont. L'amplititude du renouvellement de la nappe phréatique par rapport aux pertes de transmission des lits dépende du volume de la crue et de la durée pendant laquelle le sol reste humide ainsi que des caractères physiques du profil du sol. Le volume et la durée des crues sont les facteurs les plus importants qui influencent le volume cumule d'infiltration et la montée du niveau d'eau de la nappe phréatique peu profonde. Etant donné l'influence des différents caractéristiques de régime hydrologique et du lit du ouadi, on propose plusieurs équations du régressions pour évaluer la perte de transmission de l'eau dans le lit du ouadi et la recharge de la nappe souterraine.

“…For a stream or a canal hydraulically connected with an aquifer, the exchange of flow rate between the stream/canal and the aquifer is assumed to be linearly dependent on the potential difference causing flow (Aravin and Numerov 1965;Herbert 1970;Morel-Seytoux and Daly 1975;Besbes et al 1978;Flug et al 1980). Bouwer (1969) reported that when water table lies at shallow depth, recharge from a canal to an aquifer is directly proportional to the difference in water levels in the canal and the aquifer.…”

The article presents semi-analytical mathematical models to asses (1) enhancements of seepage from a canal and (2) induced flow from a partially penetrating river in an unconfined aquifer consequent to groundwater withdrawal in a well field in the vicinity of the river and canal. The nonlinear exponential relation between seepage from a canal reach and hydraulic head in the aquifer beneath the canal reach is used for quantifying seepage from the canal reach. Hantush's (1967) basic solution for water table rise due to recharge from a rectangular spreading basin in absence of pumping well is used for generating unit pulse response function coefficients for water table rise in the aquifer. Duhamel's convolution theory and method of superposition are applied to obtain water table position due to pumping and recharge from different canal reaches. Hunt's (1999) basic solution for river depletion due to constant pumping from a well in the vicinity of a partially penetrating river is used to generate unit pulse response function coefficients. Applying convolution technique and superposition, treating the recharge from canal reaches as recharge through conceptual injection wells, river depletion consequent to variable pumping and recharge is quantified. The integrated model is applied to a case study in Haridwar (India). The well field consists of 22 pumping wells located in the vicinity of a perennial river and a canal network. The river bank filtrate portion consequent to pumping is quantified.

The Cauvery river's present dwindling annual flow of less than 50 per cent of normal prompted the study of its hydrochemistry and those of its adjoining well waters as influenced by seasonal rains. At Musiri gauging station the river hydrochemistry showed quiescent behavior during winter and summer, exhibiting dilution with increase in discharge during southwest monsoon and concetration during northeast monsoon. Wells in alluvium had rapid responses regaining their water levels and hydrochemistry. Hardrock wells exhibited rapid declines. Dilution took place in the nearby adjoining alluvial wells and distant hardrock wells after the northeast monsoon. Concentration tookplace in the nearby hardrock wells after the northeast monsoon. Long term river hydrochemistry revealed that due to steady decrease in river discharge the concentrations were on the increase. WATSPEC effective soeciation confirmed that the river and well waters were supersaturated with respect to calcite and dolomite and undersaturated with respect to gypsum and halite.
