Description
A case study of a shallow, well mixed fjord illustrates the use of radioactive and an activable tracer. An instantaneous injection of the rare earth lanthanum was used as an activable tracer to determine residence-time and internal recirculation in the fjord system. An instantaneous injection of bromine-82 was used to investigate tae bypass of water from a harbour area through a power plant cooling water system to a partly enclosed basin of the fjord. Instantaneous releases of bromine-82 were further used for short time studies of the primary spread and transport of river water discharged to the inner section of the fjord system. (Author)

O estudo de um fiorde de aguas rasas e bem misturadas ilustra o emprego de um tracador radioativo e de um tracador ativavel. Utilizou-se uma injecao instantanea de lantanio como tracador ativavel para determinar o tempo de residencia e a recirculacao interna no sistema do fiorde. Empregou-se uma injecao instantanea de bromo-82 para investigar o desvio da agua proveniente de uma area de baia atraves de um sistema de refrigeracao de uma usina ate uma bacia do fiorde parcialmente fechada. Utilizaram-se, alem disso, liberacoes instantaneas de bromo-82 para estudos de tempos curtos de dispersao primaria, e de transporte de aguas de rio lancadas na parte interna do fiorde. (M.A.)Files
