“…The 12 papers present in this issue cover a number of important topics related to urban soils and sediments, such as soil formation (Burghardt and von Berhrab 2016), structure amelioration (Zimmermann et al 2016), spatial and temporal water dynamics (Wiesner et al 2016), human impact on urban park soils (Sarah et al 2016;Zhao and Hazelton 2016), the application of spectroscopy to urban soil studies (Kopel et al 2016), green roof soils (Jelinkova et al 2016), urban streamflow regimes (Ferreira et al 2016a), and the transport of sediments, heavy metals, and polychlorinated biphenyl in urban areas runoff (Dias-Ferreira et al 2016;Ferreira et al 2016b, c;Silveira et al 2016). This volume presents the latest research and case studies from several urban areas located in Europe, America, Australia, and Asia, contributing to the knowledge of urban soil and sediment dynamics at the international level.…”
