“…It is also applicable to most types of groundwater modelling problems and accepted by many agencies both in the USA and internationally. Examples of MODFLOW application include assessing change to Amsterdam Water supply system caused by addition and removal of wells (Olsthoorn, 1999); groundwater simulation and scenario analysis in Jordan (Al-Kharabsheh, 2000); simulation of drawdown and field operation in discontinuous layers in Kuwait (Szekely et al, 2000); investigation of possible alternatives for effective groundwater management in eastern Saudi Arabia (Rasheeduddin et al, 2001); and the simulation of groundwater in multilayer aquifer system in southwest Egypt (Ebraheem, 2002). Boronina et al (2003) also used MODFLOW in south Cyprus (a semi-arid climate experiencing a scarcity of water resources as in Libya) for water balance and recharge rate estimation at the Kouris basin.…”
