To minimize flood damages, one of the crucial factors is the identification of flood prone areas through fluvial hydraulic modelling in which a detailed knowledge of the terrain plays an important role for reliable results. Recent studies have demonstrated the suitability of the Reduced Cost Aerial Precision Photogrammetry (RC-APP) technique for fluvial applications by accurate-detailed-reliable Digital Terrain Models (DTMs, up to: \u2248100 point\/m2; vertical-uncertainty: \u00b10.06 m). This work aims to provide an optimal relationship between point densities and vertical-uncertainties to generate more reliable fluvial hazard maps by fluvial-DTMs. This is performed through hydraulic models supported by geometric models that are obtained from a joint strategy based on Structure from Motion and Cloth Simulation Filtering algorithms. Furthermore, to evaluate vertical-DTM, uncertainty is proposed as an alternative approach based on the method of robust estimators. This offers an error dispersion value analogous to the concept of standard deviation of a Gaussian distribution without requiring normality tests. This paper reinforces the suitability of new geomatic solutions as a reliable-competitive source of accurate DTMs at the service of a flood hazard assessment.<\/jats:p>","DOI":"10.3390\/rs10101566","type":"journal-article","created":{"date-parts":[[2018,10,2]],"date-time":"2018-10-02T08:23:50Z","timestamp":1538468630000},"page":"1566","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Flood Hazard Assessment Supported by Reduced Cost Aerial Precision Photogrammetry"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0265-1590","authenticated-orcid":false,"given":"Santiago","family":"Zazo","sequence":"first","affiliation":[{"name":"TIDOP Research Group, University of Salamanca, Avda. de los Hornos Caleros, 50, 05003 \u00c1vila, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2657-813X","authenticated-orcid":false,"given":"Pablo","family":"Rodr\u00edguez-Gonz\u00e1lvez","sequence":"additional","affiliation":[{"name":"TIDOP Research Group, University of Salamanca, Avda. de los Hornos Caleros, 50, 05003 \u00c1vila, Spain"},{"name":"Department of Mining Technology, Topography and Structures, University of Leon, Avda.
