This study investigates differences in the concentration of total sediments (TSC) and suspended sediments (SSC) in the small peri-urban Mediterranean Ribeira dos Cov\u00f5es catchment (40% urban area) in central Portugal. Suspended sediment responses at the catchment outlet (E) and in three upstream sub-catchments, during periods of urbanization (2011\u20132013) and stabilizing land-use (2017\u20132018) are compared for storm-event datasets encompassing similar ranges of rainstorm sizes and antecedent rainfall condition. The Quinta sub-catchment, with the lowest urban area (22%) but subject to major construction activities affecting 17% of its area, led to highest TSC and SSC during urbanization (attaining 4320 mg\/L and 4184 mg\/L, respectively), and a median reduction of 38% and 69%, respectively, during stabilization. Esp\u00edrito Santo sub-catchment, with highest urban area (49%) and minor construction activities, displayed similar median TSC in both periods (258\u2013240 mg\/L) but highest SSC reduction (76%), highlighting the impact of the anthropogenic disturbance mainly on fine-particle sediments and a good connectivity with the stream. Porto Bordalo sub-catchment, with 39% urban area and subject to the construction of a four-line road covering 1.5% of its area, showed the lowest TSC and SSC concentrations and the lowest median reductions in both periods (31% and 64%, correspondingly), mainly because of the impact of an unplanned retention basin established with soil from the construction site. Overall, median TSC and SSC reduced 14% and 59% at E, from urbanization to stabilization. Information about sediment dynamics should guide stakeholders in establishing strategies to reduce sediment loads and mitigate the impacts on urban aquatic ecosystems.<\/jats:p>","DOI":"10.3390\/w12030665","type":"journal-article","created":{"date-parts":[[2020,3,2]],"date-time":"2020-03-02T07:50:53Z","timestamp":1583135453000},"page":"665","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Impact of Land-Use Changes on Spatiotemporal Suspended Sediment Dynamics within a Peri-Urban Catchment"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3709-4103","authenticated-orcid":false,"given":"C.S.S.","family":"Ferreira","sequence":"first","affiliation":[{"name":"Research Centre for Natural Resources, Environment and Society (CERNAS), Polytechnic Institute of Coimbra, Higher Agricultural School, Coimbra 3045-601, Portugal"}]},{"given":"R.P.D.","family":"Walsh","sequence":"additional","affiliation":[{"name":"Department of Geography, College of Science, Swansea University, Swansea SA2 8PP, UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7978-0040","authenticated-orcid":false,"given":"Z.","family":"Kalantari","sequence":"additional","affiliation":[{"name":"Department of Physical Geography and Bolin Centre for Climate Research, Stockholm University, Stockholm SE-10691, Sweden"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5686-9192","authenticated-orcid":false,"given":"A.J.D.","family":"Ferreira","sequence":"additional","affiliation":[{"name":"Research Centre for Natural Resources, Environment and Society (CERNAS), Polytechnic Institute of Coimbra, Higher Agricultural School, Coimbra 3045-601, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2020,3,1]]},"reference":[{"key":"ref_1","unstructured":"(2006).
