    Morfología Fluvial.-Una paradoja en la restauración de canteras de caliza en el área mediterránea: características físicas del sustrato como condicionante de la dinámica del sistema creado

    ABSTRACT The restoration of opencast mining land looks for the quick integration in the landscape and the erosion control of derelict areas. The characteristics of substrate can determinate the behaviour of novel system. The stony substrates used have a great Ks and a very low water storage capacity. This paper presents the results of an experiment performed on stony mineral substrates amended with sewage sludge under Mediterranean climatic conditions in a limestone quarry in the SW of Barcelona (NE of Spain). The experiment was carried out at container scale and the aim was to evaluate the vegetation response in two substrates with different stoniness and with irrigation during dry period. Water content in the mineral substrate was monitored using vertical TDR probes during the experiment. The growth of introduced plants was monitored monthly. Throughout the experiment, populations of sown plants fluctuated according to the available water in the substrate. The irrigation applied was not sufficient to maintain the vegetation in summer (period of higher evaporative demand at that time of year). The volume of leachate was high and nitrates, sulfates and chlorides were washed
