Abstract
A bromide tracer applied to a cracked clay soil was adsorbed in the soil matrix close to the soil surface. Upon subsequent precipitation, a small part of the bromide dissolved and flowed rapidly through cracks to the subsoil and the groundwater. As a result, the groundwater and the drain discharge showed considerable solute concentration peaks in the first days after application. The first drain outflow contained a bromide concentration of about 0.1% of the applied bromide solution. Subsequent precipitation events continued to cause concentration peaks in both groundwater and drain discharge.
