There is no doubt that water is one of the most important inputs in agricultural production in Ghana apart from labour. More importantly almost all agricultural productions depend on natural rainfall. Therefore, crop yields are invariably poor since the rains are very erratic. Groundwater development for irrigation should therefore be really looked at since it constitutes about 30.1% of the available freshwater on earth.The potential use of shallow groundwater for small-scale dry season irrigation is a key issue for irrigation development in the arid zone of Ghana. Farmers within the Atankwidi sub-basin of the White Volta Basin are increasingly using groundwater as a source for irrigation due to the unavailability of surface water in the dry season, hence the need to investigate its availability and suitability in order to ensure sustainability in the application and possible expansion in the area. The aquifer geometry in the Atankwidi sub-basin has therefore been successfully delineated using geophysical (VES and EM) techniques. Groundwater quality (suitability) for irrigation has also been successfully determined.

Shallow groundwater systems are important as a source of water, for sustenance of stream baseflow, and for wetland and riparian ecosystems. They are also central to waterlogging, and dryland and irrigation salinity problems. Response time to hydrologic change and pollutant loadings is fast among shallow aquifiers, and it is important that hydrogeologists and natural resource managers understand the unsaturated zone processes which links human activity at the soil surface and the underlying groundwater, and vice versa. This volume of papers explores practical aspects of soil and surface water interactions with groundwater, including modelling of flow and contaminant transport in the unsaturated and saturated zones.

This book was released on 2009. Hydrogeological and Hydrochemical Framework of Complex Volcanic System in the Upper Awash River Basin, Central Ethiopia available in PDF, EPUB and Kindle. Integrated approach has been used to investigate the hydrogeological framework of a complex fractured volcanic aquifer system in the Upper Awash river basin located at the western shoulder of the Ethiopian rift. The groundwater flow system and mechanism of recharge of different aquifers have been studied using conventional hydrogeological field investigations, hydrochemistry, isotope hydrology and numerical groundwater flow modeling techniques. Litho-hydrostratigraphic relationships were constructed from lithologic logs obtained from exploratory drilling of deep boreholes. The result indicates quite complex flow pattern and hydraulic characteristics of the different volcanic aquifers. The litho-hydrostratigraphic correlation indicates that the permeable and porous scoraceous lower basaltic aquifer is extended laterally all the way from the Blue Nile Plateau to the study area. .The analysis of the temporal and spatial variation of water samples from different places revealed clear undwater-surface water interactions. New evidences have also emerged on the inter-basin groundwater transfer. Two distinct regional basaltic aquifers (Upper and lower) are identified showing distinct hydrochemical and isotopic signatures. In the southern part of the study area the upper and lower aquifers form one unconfined regional aquifer system. In the northern and central part of the basin, it appears that the two systems are separated by regional aquiclude forming confined aquifers, in places with artesian wells. The groundwater from the deep exploratory wells (>250m) tapping the lower basaltic aquifer and wells located in the south were found to be moderately mineralized (TDS: 400-600 mg/l), with relatively depleted stable isotope composition and with almost zero tritium. In contrast, the upper shallow aquifer has lesser ionic concentration, more isotopically enriched. Evidences from the different methods clearly indicate inter-basin groundwater transfer from the Blue Nile basin to the Upper Awash basin. The evidences also converge to testify common origin of recharge, presence of hydraulic connectivity for systems tapping the lower basaltic aquifer. This has enormous practical implication in finding large groundwater reserve at a greater depth that can solve the current water supply problems of the community including the capital Addis Ababa. It will also have important role in finding more regional aquifers along the plateau-rift margins in many areas having similar hydrogeological setup as the study area.
