“…Network science has been adopted by many in the natural sciences to study a range of phenomena. In the environmental sciences, this has inspired a generation of connectivity researchers in ecology, geomorphology, and hydrology (Larsen et al 2017; Masselink et al 2017; Paton et al 2019). The shared conceptual and methodological toolset has fostered cross‐pollination among these communities (Turnbull et al 2018), and increasingly informs much research in social‐ecological systems and sustainability science (Cumming et al 2010; Tonini and Liu 2017; Groce et al 2019).…”

Methods and concepts from network analysis can provide valuable empirics and novel insights for critical physical geography and related fields.• Network approaches can help to bridge human-physical and qualitative-quantitative divides in geographical research. • Critical physical geographers and network scholars have much to gain from collaboration.Critical physical geography (CPG) calls for integrative research on material landscapes and the socio-political dynamics of scientific knowledge production. Network analysis, a rich tradition of tools and approaches for analyzing relational information, has seen little use in the CPG literature to date. This represents a fruitful opportunity, as many of CPG's core interests-knowledge politics, histories of scientific concepts, and ecosocial relations-can be effectively analyzed using network techniques. In this article, I argue for adapting network approaches to CPG. First, I provide an overview of various network concepts, approaches, and their origins. I then discuss bibliometric network techniques for "science mapping" including co-word, co-authorship, and citation analyses. Next, I describe discourse network analysis, a recent mixed-method approach from political science. Finally, I discuss overlaps with emerging approaches from qualitative and visual network analysis. In each section, I provide existing and hypothetical examples, as well as software and visualization techniques, that demonstrate how network approaches could add new insights to CPG and related scholarship. Linking CPG with the diverse traditions of network analysis has the potential to produce new empirical understandings and bring the field into conversation with a growing body of research that spans the social sciences, natural sciences, and humanities.

“…Despite their relevance to hydro-sedimentological processes, gullies are often neglected in models (Poesen, 2018) and should be directly addressed (Paton et al, 2019). However, gully erosion is a process that involves the interaction of many variables, with several of them being difficult to assess (Bernard et al, 2010;Castillo and Gómez, 2016).…”

Abstract. Gullies lead to land degradation and desertification as well as increasing environmental and societal threats, especially in arid and semiarid regions. Despite this fact, there is a lack of related research initiatives. In an effort to better understand soil loss in these systems, we studied small permanent gullies, which are a recurrent problem in the Brazilian northeastern semiarid region. The increase in sediment connectivity and the reduction of soil moisture, among other deleterious consequences, endanger this desertification-prone region and reduce its capacity to support life and economic activities. Thus, we propose a model to simulate gully-erosion dynamics, which is derived from the existing physically based models of Foster and Lane (1983) and Sidorchuk (1999). The models were adapted so as to simulate long-term erosion. A threshold area shows the scale dependency of gully-erosion internal processes (bed scouring and wall erosion). To validate the model, we used three gullies that were over 6 decades old in an agricultural basin in the Brazilian state of Ceará. The geometry of the channels was assessed using an unmanned aerial vehicle and the structure from motion technique. Laboratory analyses were performed to obtain soil properties. Local and regional rainfall data were gauged to obtain sub-daily rainfall intensities. The threshold value (cross-section area of 2 m2) characterizes when erosion in the walls, due to loss of stability, becomes more significant than sediment detachment in the wet perimeter. The 30 min intensity can be used when no complete hydrographs from rainfall are available. Our model could satisfactorily simulate the gully-channel cross-section area growth over time, yielding a Nash–Sutcliffe efficiency of 0.85 and an R2 value of 0.94.

Tracing hydrological connectivity

When investigating fundamental hydrological functions of catchments (i.e. collection, storage and release of water and matter), the spatial and temporal variability of hydrological connectivity is a key element (Black, 1997). Introduced in hydrology in the early 1980s by Burt & Gadiner (1982), the concept of hydrological connectivity has only recently attracted the attention of the scientific community. Over the past two decades, hydrological connectivity has become an important conceptual framework within which the spatial and temporal variability of streamflow generation and sediment transport can be conceptualised from a holistic perspective, considering the structural and functional connectivity between the Chapter structures and connectivity pathways (Cammeraat, 2002;Wohl et al., 2019). Failure in assessing these heterogeneities may lead to erroneous process conceptualisation and discrepancies between processes observed at smaller scales and responses that may occur at larger scales (Ward and Packman, 2019). Assessing system heterogeneities is also particularly important for restoration purposes (Ward and Packman, 2019;Wohl et al., 2019), since the management of systems' hydrological (and ecological) functions should account for this variability to be properly implemented.Recently, Wohl et al. (2019) and Blöschl et al. (2019) have highlighted the need to consider hydrological systems as borderless, in a way that the transition zones (or interfaces) between different landscape elements should be characterised for their own processes and fluxes to have a better perception of where and when connectivity may take place. Similarly, Krause et al. ( 2017) stressed the importance of system interfaces as "hot spots of ecological, biogeochemical and hydrological processes" arguing that an improved understanding of large-scale landscape interactions will only be possible once interface processes would be incorporated in system conceptualisation. Advancing hydrological connectivity understanding through interdisciplinary approachesWhen investigating hydrological systems connectivity, it is fundamental to consider the ecological and geomorphic components of the landscape and the way they interact with the hydrological components. In this sense, research on hydrological connectivity intrinsically requires a certain level of interdisciplinarity (i.e. incorporating knowledge and techniques from different disciplines) (Paton et al., 2019;Turnbull et al., 2018). During the last decade, several authors have emphasised the importance of interdisciplinary approaches -and of improving the dialogue between hydrologists and specialists of different disciplines -in order to further advance our understanding of hydrological connectivity (Cooper, 2010;Smith et al., 2019;Wainwright et al., 2011). More specifically, Wainwright et al. (2011) suggested that we should focus on developing new interdisciplinary approaches able to obtain information about the system's structure (spatial variability) and functions (both spatial and temporal va...
