Eutectic Systems for Penetration EnhancementAlluvial terrain covers less than 25 % of the land surface of the country (Fig. 3.1) however, major prolific aquifers and larger groundwater storage lay in this zone (Fig. 1.1). Investment on groundwater schemes is, could therefore, much more feasible in the regions underlain by alluvial aquifers.

M. Vargas,A. Marra,G. Servillo,P. PelosiGroundwater resource is the pillar of socio-economic activity and environment functions. Unlike in most part of Africa where groundwater is stored in extensive continental scale groundwater reservoirs, the groundwater resources of Eastern Africa are known for their low storage and shallow circulation.

Groundwater Occurrence in Regions and Basins,The broad volcanic plateau (Fig. 1.2) accounts for about 25 % of Ethiopian landmass. The Ethiopian volcanic plateau is a thick monotonous, rapidly erupted pile of locally deformed, flat lying basalts consisting of a number of volcanic centers with different magmatic character and with a large range of ages.

Geochemistry and Water Quality,Water quality is the measure of physical, chemical, radiological and biological property of water. Water quality poses limits on the suitability of water use for a particular development purpose.

Groundwater Potential, Recharge, Water Balance: Vital Numbers,Groundwater potential is measured by (a) recharge rate and mechanism, (b) aquifer storage and transmission properties, and (c) suitability of the water from water quality point of view and (d) the response of the aquifer to changes such as climate, seasonality, artificial withdrawal and pollution.

Functions of Groundwater,ugh which solute (such as silica, nitrate, and cations) enters into lake and ultimately supports the phytoplankton and zooplanktons. Groundwater sustains aquatic ecological functions in rivers, lakes, riparian zones and estuaries require huge volumes of water. Fresh water sustains biomass growth in
