Special Issue Information
Dear Colleagues,
This special issue aims to provide a common forum to share knowledge about the growing threat of Geohazards such as landslides and rock slides, earthquakes, floods, tsunamis, coastal erosion, drought among many others, due to the expanding size the cities and urban areas, critical use of agricultural lands, the increased use of infrastructure, and the effect of climate changes.
Original work related to the topic is welcomed, along with side topics if demonstrated to have a direct application into the theme, such as field surveys, numerical modelling, statistical analysis, monitoring, vulnerability and risk assessment, mitigation and adaptation strategies.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2300 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The accurate estimation of flood risk depends, among other factors, on a correct estimate of the floodable area and its associated hydrodynamic parameters. This characterisation becomes fundamental in the flood hazard analyses carried out in urban areas, especially when we are faced with the presence of cultural heritage sites. To achieve this objective, it is necessary to have a correct characterisation of the topography. Outside the riverbed, the LiDAR data have meant an important improvement, but not so inside the riverbed, due to the general inability to penetrate the water bodies. To overcome these deficiencies, different approach have been developed to simulate this bathymetry using simplified models. Here, we present a model based upon the calibration of the Manning´s n value inside the riverbed. The use of these abnormally low Manning´s n values has made it possible to reproduce both the extent of the flooded area and the flow depth value within it in an acceptable manner: the reduction of the flow depth average error from 50-75 cm to only about 10 cm, and a direct flood damage differences from 25-30% to values of about 5%. More robust geostatistical analysis of hydrodynamic modelling outputs, use of spatially distributed non-uniform Manning´s n values, and other improvements will enable more robust and reliable results to be obtained. But, even without an associated calibration process, the use of lower n values can halve errors in the estimation of flow depth, improving flood hazard analysis especially in those areas that are socio-economically weaker.
