Geomorphological Processes and Natural Hazards

All manuscripts should be submitted to remotesensing@mdpi.com with a copy to the Guest Editor. Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as 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 refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Remote Sensing is an international peer-reviewed Open Access monthly 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 300 CHF per accepted paper. English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.

Abstract: This paper is focused on the combination of instrumental rainfall records, field data, hydrologic and hydraulic modelling, GIS and remote sensing techniques applied to estimate magnitude of floods in ephemeral channels (ramblas) on the coastal zone in Southest Spain. These constitute an important natural hazard due to their high discharges and sediment loads. Rainfall-surface runoff models (SCS Dimensionless Unit Hydrograph –SCSD-, Témez gamma HU –Tγ- and the Modified Rational method –MRM-) integrated in a GIS (Geographic Information System) to obtain spatially distributed data, and methods of hydraulic geometry combined with remotely sensed data, were compared with flood hydrographs of the ASHI (Automatic System of Hydrologic Information) in the coastal Benipila rambla (Murcia Region). Area affected by floods during the period 1970 to 2009 was delimited through HEC-GeoRAs from rainfall–runoff conversion data and using Landsat images of these floods. Best-fit results were used to calculate different geomorphological parameters, specially capacity of bed load, concentration of sediments in suspension, channel stability and transitory bed erosion. All these aspects have a great usefulness to determine the safety degree of road links, the efficiency of drainage works and potential problems of obstruction. A last considered aspect is the intense and undue occupation of the fluvial space in most of these ramblas, turned today into an important hazard factor, so much for its direct exposure to flood events as for its negative effects on the hydraulic regime.

Title: Effects of Collapse Processes
Author: Viacheslav Andreychouk; E-Mail: geo@wnoz.us.edu.pl
Abstract: Collapse dolines formation is most often an eminently dynamic process. Fast ground surface subsidence are usually accompanied by different physical phenomena (effects) like, e.g., acoustic, luminous, pneumatic etc. Recent data and author’s field observations enable him to propose the first classification of phenomena accompanying collapse doline formation. They can be classified based on the following criteria:
- place of appearing (local – within the limits of collapse doline and areal – in collapse doline surroundings);
- time of appearing (before collapse doline formation – pre-collapse, during collapse doline formation – collapse-time and after collapse doline formation - post-collapse);
- physical nature of effects (acoustic, luminous, pneumatic, seismic, hydrodynamic types with subtypes).
Due to their diagnostic, forecasting, engineering-geological significance, the phenomena (effects) accompanying the collapse doline formation should be thoroughly investigated.

Title: Geomorphological Patterns of the Earthquake Hazard Zones on India-Eurasia Plate Collision Boundary

Abstract: Study area lies at the western end of the Indo-Asian collision zone. Basic geomorphologic features are defined by active faults of different kinematics, such as Chaman, Heart, Darvaz faults, Central Badakhsan fault zone and others. Besides morphotectonic and seismic settings are controlled by active intracontinental subduction beneath the Pamir–western Himalayan syntaxis. Study region is known as one of the major seismic area and at the present day there are numerous thematic investigations including earthquake hazards maps. In this paper we attempted to delineate different geomorphological patterns for the different earthquake hazard zones in the region based on remote sensing data. Both satellite images and radar topographic data were used in the investigation. Analysis of correlation between multiple-aged plains of subaerial denudation, neotectonic active fault sets and disposition of seismic hazard zones using GIS technology was carried out. The analysis results allow characterizing geomorphological structure of active fault systems for earthquake hazard zones.
