This study sought to quantitatively relate morphological adjustments in the Azoh\u00eda Rambla, a gravel-bed ephemeral stream in southeastern Spain, to stream power (\u03c9), critical power (\u03c9c), and energy gradients (\u2202\u03c9\/\u2202s), along different reference channel reaches of 200 to 300 m in length. High-resolution digital terrain models (HRDTMs), combined with ortophotographs and point clouds from 2018, 2019, and 2020, and ground-based surveys, were used to estimate the spatial variability of morphological sediment budgets and to assess channel bed mobility during the study period at different spatial scales: reference channel reaches (RCRs), pilot bed survey areas (PBSAs), and representative geomorphic units (RGUs). The optimized complementary role of the SfM technique and terrestrial laser scanning allowed the generation of accurate and reliable HRDTMs, upon which a 1-D hydrodynamic model was calibrated and sediment budgets calculated. The resulting high-resolution maps allowed a spatially explicit analysis of stream power and transport efficiency in relation to volumes of erosion and deposition in the RCR and PBSA. In addition, net incision or downcutting and vertical sedimentary accretion were monitored for each flood event in relation to bedforms and hydraulic variables. Sediment sources and sinks and bed armoring processes showed different trends according to the critical energy and stream power gradient, which were verified from field observations. During flows exceeding bankfull discharges (between 18 and 24 m3 s\u22121 according to channel reach), significant variations in \u2202\u03c9\/\u2202s values and \u03c9\/\u03c9c ratios (e.g., \u221215 &lt; \u2202\u03c9\/\u2202s &lt; 15 Wm\u22123; \u03c9\/\u03c9c &gt; 2 for a peak discharge of 31 m3 s\u22121) were associated with a large amount of bedload mobilized upstream and vertical accretion along the middle reach (average rise height of 0.20 to 0.35 m for the same event). By contrast, more moderate peak flows (\u226410 m3 s\u22121) only produced minor changes resulting in surface washing, selective transport, and local bed scouring.<\/jats:p>","DOI":"10.3390\/rs12213624","type":"journal-article","created":{"date-parts":[[2020,11,5]],"date-time":"2020-11-05T00:00:37Z","timestamp":1604534437000},"page":"3624","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Combining SfM Photogrammetry and Terrestrial Laser Scanning to Assess Event-Scale Sediment Budgets along a Gravel-Bed Ephemeral Stream"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3818-5421","authenticated-orcid":false,"given":"Carmelo","family":"Conesa-Garc\u00eda","sequence":"first","affiliation":[{"name":"Department of Physical Geography, University of Murcia, 30001 Murcia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4509-4691","authenticated-orcid":false,"given":"Carlos","family":"Puig-Mengual","sequence":"additional","affiliation":[{"name":"Institut d\u2019Investigaci\u00f3 per a la Gesti\u00f3 Integrada de Zones Costaneres (IGIC), Universitat Polit\u00e8cnica de Val\u00e8ncia (UPV), 46730 Gandia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2155-3515","authenticated-orcid":false,"given":"Adri\u00e1n","family":"Riquelme","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, University of Alicante, 03080 Alicante, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2947-9441","authenticated-orcid":false,"given":"Roberto","family":"Tom\u00e1s","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, University of Alicante, 03080 Alicante, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4991-0251","authenticated-orcid":false,"given":"Francisco","family":"Mart\u00ednez-Capel","sequence":"additional","affiliation":[{"name":"Institut d\u2019Investigaci\u00f3 per a la Gesti\u00f3 Integrada de Zones Costaneres (IGIC), Universitat Polit\u00e8cnica de Val\u00e8ncia (UPV), 46730 Gandia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4495-4944","authenticated-orcid":false,"given":"Rafael","family":"Garc\u00eda-Lorenzo","sequence":"additional","affiliation":[{"name":"Department of Physical Geography, University of Murcia, 30001 Murcia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7870-3652","authenticated-orcid":false,"given":"Jos\u00e9 L.","family":"Pastor","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, University of Alicante, 03080 Alicante, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pedro","family":"P\u00e9rez-Cutillas","sequence":"additional","affiliation":[{"name":"Department of Physical Geography, University of Murcia, 30001 Murcia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5737-9299","authenticated-orcid":false,"given":"Miguel","family":"Cano Gonzalez","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, University of Alicante, 03080 Alicante, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,11,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"199","DOI":"10.1016\/j.geomorph.2013.06.021","article-title":"Assessment of channel changes in a Mediterranean ephemeral stream since the early twentieth century.
