“…The Kuwait Group aquifer is generally in an unconfined state, whereas the Dammam Formation is confined. A detailed description of the aquifers is given by Mukhopadhyay et al (1994) and Amer et al (1990). The ground-water table varies from approximately 90 m above mean sea level in the south-west, and decreases to zero at the Gulf coast (Fig.…”

“…The transmissivity for Raudhatain was estimated as 840 m 2 day !1 and the storage coefficient was about 0)1. Aquifer parameter values for the entire region were estimated by Mukhopadhyay et al (1994) by numerical modelling. The values for transmissivity varied between 170 and 260 m 2 day !1 and the storage coefficient was about 0)08.…”

“…Sedimentary basins form important groundwater resources for the intramontane areas of Spain (LoÂ pez- Vera et al, 1981;Cruz-SanjuliaÂ n et al, 1990), and in addition such basins are frequently the only water resources in many semi-arid and arid regions in the world (Robertson, 1989;Mukhopadhyay et al, 1994;Rosen and Jones, 1998;Birkle et al, 1998).…”

The physical±chemical characteristics of the groundwater in the Baza±Caniles detrital aquifer system indicate that a wide diversity of hydrochemical conditions exists in this semiarid region, de®ning geochemical zones with distinct groundwater types. The least mineralized water is found closest to the main recharge zones, and the salinity of the water increases signi®cantly with depth towards the center of the basin. Geochemical reaction models have been constructed using water chemistry data along¯ow paths that characterize the di erent sectors of the aquifer system, namely: Quaternary aquifer, uncon®ned sector and shallow and deep con®ned sectors of the Mio±Pliocene aquifer. Geochemical mass±balance calculations indicate that the dominant groundwater reaction throughout the detrital system is dedolomitisation (dolomite dissolution and calcite precipitation driven by gypsum dissolution); this process is highly developed in the central part of the basin due to the abundance of evaporites. Apart from this process, there are others which in¯uence the geochemical zoning of the system. In the Quaternary aquifer, which behaves as a system open to gases and which receives inputs of CO 2 gas derived from the intensive farming in the area, the interaction of the CO 2 with the carbonate matrix of the aquifer produces an increase in the alkalinity of the water. In the shallow con®ned sector of the Mio±Pliocene aquifer, the process of dedolomitisation evolves in a system closed to CO 2 gas. Ca 2+ /Na + cation exchange and halite dissolution processes are locally important, which gives rise to a relatively saline water. Finally, in the deep con®ned sector, a strongly reducing environment exists, in which the presence of H 2 S and NH + 4 in the highly mineralized groundwater can be detected. In this geochemical zone, the groundwater system is considered to be closed to CO 2 gas proceeding from external sources, but open to CO 2 from oxidation of organic matter. The geochemical modeling indicates that the chemical characteristics of this saline water are mainly due to SO 4 dissolution, dedolomitisation and SO 4 reduction, coupled with microbial degradation of lignite. #

Abstract:Groundwater flow modelling of the Kwa Ibo River watershed in Abia State of Nigeria is presented in this paper with the aim of assessing the degree of interaction between the Kwa Ibo River and the groundwater regime of the thick sandy aquifer. The local geology of the area comprises the Quaternary to recent Benin Formation. Potential aquifer zones that were delineated earlier using geoelectrical resistivity soundings and borehole data for the area formed the basis for groundwater flow modelling. The watershed has been modelled with a grid of 65 rows by 43 columns and with two layers. Lateral inflow from the north has been simulated with constant heads at the Government College, Umuahia, and outflow at Usaka Elegu in the south. The Kwa Ibo River traverses the middle of the watershed from north to south. The river-stage data at Umudike, Amawom, Ntalakwu and Usaka Elegu have been used for assigning surface water levels and riverbed elevations in the model. Permeability distribution was found to vary from 3 to 14Ð5 m day 1 . Natural recharge due to rainfall formed the main input to the aquifer system, and abstraction from wells was the main output. A steady-state groundwater flow simulation was carried out and calibrated against the May 1980 water levels using 26 observation wells. The model computations have converged after 123 iterations. Under the transient-state calibration, the highest rainfall (and hence groundwater recharge) over the 10-year study period was recorded in 1996, whereas the lowest was recorded in 1991. The computed groundwater balance of 55 274 m 3 day 1 was comparable to that estimated from field investigations. Results from the modelling show that abstraction is much less than groundwater recharge. Hence there is the possibility for additional groundwater exploitation in the watershed through drilling of boreholes.
