“…Transport of matter and energy through the soil (Bryan, 2000;Blum, 2005;Kovacs, 2012) is just one example of processes that show the dynamics of the pedosphere in part influenced by natural factors (Smith et al, 2015). Important biological and hydrological functions provided by the soil are at risk due to an anthropogenic overuse or mismanagement (Tarolli and Sofia, 2016;Tarolli, 2016), which can lead to erosion and degradation of soil, and the partial destruction of soil functions and resources (Costantini et al, 2015;Cerdà et al, 2016).…”

“…These changes in the economic sector seem to be in line with the changes highlighted by the drainage network analysis. The drainage density was 28.2 km/km 2 Despite the general decline, it is interesting to notice in some areas the efficiency of the network increased (blue colours in Figure 4c,f). In some locations, this depended on the creation of engineering projects, such as retention basins and some deep artificial channels.…”

“…Raising interest in the importance of human drivers to understand the past and current development of our planet is of great importance [1,2]. Both the landscape and the river systems in the urbanised floodplains of Europe, and elsewhere, have undergone major changes in the past, and these environmental changes have altered the flooding conditions [3,4].…”
Amongst human practices, agricultural surface-water management systems represent some of the largest integrated engineering works that shaped floodplains during history, directly or indirectly affecting the landscape. As a result of changes in agricultural practices and land use, many drainage networks have changed producing a greater exposure to flooding with a broad range of impacts on society, also because of climate inputs coupling with the human drivers. This research focuses on three main questions: which kind of land use changes related to the agricultural practices have been observed in the most recent years (~30 years)? How does the influence on the watershed response to land use and land cover changes depend on the rainfall event characteristics and soil conditions, and what is their related significance? The investigation presented in this work includes modelling the water infiltration due to the soil properties and analysing the distributed water storage offered by the agricultural drainage system in a study area in Veneto (north-eastern Italy). The results show that economic changes control the development of agro-industrial landscapes, with effects on the hydrological response. Key elements that can enhance or reduce differences are the antecedent soil conditions and the climate characteristics. Criticalities should be expected for intense and irregular rainfall events, and for events that recurrently happen. Agricultural areas might be perceived to be of low priority when it comes to public funding of flood protection, compared to the priority given to urban ones. These outcomes highlight the importance of understanding how agricultural practices can be the driver of or can be used to avoid, or at least mitigate, flooding. The proposed methods can be valuable tools in evaluating the costs and benefits of the management of water in agriculture to inform better policy decision-making.
New remote sensing techniques, such as airborne laser scanning (LiDAR), have led to a dramatic increase in terrain information, providing new opportunities for landform analysis. A major advance in using LiDAR‐derived high‐resolution topography (HRT) is the capability to provide an accurate and detailed terrain morphology. This study aims to use LiDAR HRT to identify palaeochannels of the Manawatu River (New Zealand) using an automated procedure based on the statistical analysis of landform curvature. The approach can provide rapid assessment and classification of floodplain topography. The proposed analysis is crucial, especially for intensively used floodplains requiring effective flood management and mitigation.
