Quantifying landscape evolution and erosion are two of the hot topics in present-day geomorphological and active tectonic research. In this regard, remote sensing has experienced a great development in the last years providing one of the main tools to get information about the present-day topography and active processes. Worldwide Digital Elevation Models (DEM) obtained from RADAR or local ones constructed by UAV or LiDAR techniques are two of the main sources of information about the present-day topography at regional and local scales respectively. Multi-temporal studies based on series of optical images, InSAR techniques or DEMs of Differences approaches provide powerful information to detect, quantify and model changes in topography and understand underlying processes. Recently adopted 4D and real-time monitoring approaches allow to elucidate the role of individual events on erosion and to establish accurate frequency-magnitude relationships.
In this special issue we want to compile the state-of-the-art research that specifically addresses how remote sensing is being used in landscape evolution studies and to monitor, quantify and model erosion. Review contributions are welcomed as well as papers describing new methodologies, or outstanding case-studies.

Abstract: High resolution data acquired via Structure from Motion (SfM) photogrammetry and Terrestrial Laser Scanner (TLS) can help improve the assessment of spatial distribution of stream power and changes in channel geometry, as well as net sediment flux. This study sought to quantitatively relate morphological adjustments in the Azohía Rambla, a gravel-bed ephemeral stream in southeastern Spain, to stream power gradient along different reference channel reaches of 200 to 450 m length. High-resolution Digital Terrain Models (HRDTM), combined with ortophotographs, point clouds acquired in 2018, 2019 and 2020, and ground-based surveys, were used to estimate the spatial variability of morphological sediment budgets to assess channel bed mobility and changes in net sediment flux during the study period.
Relationships between mean stream power gradient at peakflood discharges and volumes of erosion and deposition were quantified. In addition, downcutting and sedimentary accretion were monitored for each flood event in relation to bedforms and hydraulic variables (flow velocity, Froude number, shear stress, mean stream power, energy gradient, among others). These parameters were calculated by 1D hydrodynamic modeling and HRDTM prior entry of field information. The resulting maps allowed to compare stream power and transport efficiency with the areas of erosion and deposition in the reference channel reaches (RCR) and geomorphic representative sites (GRS). Incision and bed armouring processes showed different trends according to critical energy and power gradient, previous topographic features and bedform characteristics.
