Basic principles and details on the assessment of wastewater characterizati
on are reported for metropolitan areas with significant industrial activiti
es, with great capacity for future development. The conceptual approach rel
ated to the evaluation of pollution loads in terms of major parameters is d
efined both for domestic and industrial sources. Methods for extrapolating
generated data for the future are discussed. A procedure is developed for t
he evaluation of the expected industrial pollution profiles on the basis of
inadequate data. The proposed methodology is illustrated for Corlu as a ca
se study, a region with rapid industrialization in Turkey. (C) 1999 IAWQ Pu
