“…Alluvial river cut-andfill sequences, which typically preserve channel, floodplain and flood-basin deposits, record changes in the discharge-sediment load relationships that usually occur over periods of decades to centuries. Slackwater and boulder berm deposits, more commonly found in bedrock systems, can provide records of individual flood events that can sometimes be dated to within a decade or less (Maas and Macklin, 2002;Macklin et al, 2010).…”

“…Recent fluvial research in the Mediterranean has focused on trying to extend flood series primarily as a means of identifying changes in the frequency and magnitude of floods and relating these to atmospheric circulation patterns modulated by climate variability Thorndycraft and Benito, 2006a;Macklin et al, 2010;Luterbacher et al, 2012;Fletcher and Zielhofer, 2013). Both site-based flood chronologies (Benito et al, 2003a;Benvenuti et al, 2006;Greenbaum et al, 2006) and regionally aggregated flood histories Arnaud-Fassetta et al, 2010) have developed increasingly higher resolution chronological frameworks based on meta-analysis of large radiocarbon-dated fluvial databases.…”

Mediterranean fluvial hydrology is characterised by decadal-to-multi-centennial length wet and dry episodes with abrupt transitions related to changes in atmospheric circulation. Since the mid-1990s site-based flood chronologies from slackwater deposits in bedrock rivers and regionally aggregated flood histories from alluvial deposits have developed increasingly higher resolution chronological frameworks, although regional coverage is still uneven. This paper analyses the spatial and temporal distribution of extreme Holocene hydrological events recorded in fluvial stratigraphy in the Iberian Peninsula (Spain and Portugal), southern France, southern Italy, Northern Africa (Morocco and Tunisia) and eastern Mediterranean (Greece, Crete, Turkey, Cyprus and Israel). This study constitutes the most comprehensive investigation of Holocene river flooding ever undertaken in the Mediterranean and is based on the analysis of 515 14 C and 53 OSL dates. It reveals that flood periods in different regions cluster into distinct time intervals, although region-wide flooding episodes can be identified at

“…Deposits dated using 14 C constitute the vast majority of dated fluvial units in the UK and in many parts of the world but other radiometric methods, most notably luminescence dating techniques, have been widely employed in the study of Holocene fluvial sediments, particularly OSL dating in the European Mediterranean region (Macklin et al, 2010b). In the light of this, database compilation and analysis procedures have been adapted in order to incorporate luminescence-dated fluvial deposits (see Benito et al, 2014, this volume).…”

This paper describes developments in the analysis and interpretation of Holocene fluvial chronologies over the past 25 years. Particular consideration is given to meta-analysis approaches pioneered by Macklin and Lewin (2003), using radiocarbon-dated fluvial deposits in Britain, which have transformed fluvial geochronologies and correlations with climate and land-use records worldwide. During the last decade methodological developments have addressed issues such as correction for the shape of the radiocarbon calibration curve in the probability analysis of dated fluvial units and for variable alluvial unit preservation. The number of regional database analyses of fluvial sedimentary archives has also expanded significantly during the past decade, with studies now available for Africa, the Mediterranean region, India, Ireland, New Zealand, Poland, the Rhine catchment and the UK. Methods for incorporating optically stimulated luminescence ages in the probability analysis have also been developed and are illustrated using the database of Eastern Mediterranean dated fluvial deposits. There is considerable potential for meta-analysis research to inform long-term flood risk assessment, to evaluate short-term climate and land-use change impacts on flooding and river behaviour, and to test landscape evolution models.

“…This recognition of spatial and temporal variability in catchment connectivity is vital to grasp if management and mitigation is to be effective. Macklin et al [2010] have argued that effective slope-channel coupling renders steepland rivers responsive to both short-and longer-term environmental changes that enhance sediment production in these catchments and the examples from the Waipaoa and Ruahines demonstrate this. The impact of sediment and flood-producing events in a catchment is conditioned by the degree of coupling between landscape units within that catchment, such that well-coupled systems effectively transmit sediment generated by these events from slopes to channels, generating a response to that event [Harvey, 2001].…”

“…Steepland sediment cascades are rightly perceived as sensitive and responsive to disturbance [Macklin et al, 2010], rapidly conveying products of erosion through them at times in a highly destructive manner. Management of steepland sediment cascades therefore needs to account for complexity in behaviour of these systems, conditioned by unique threshold conditions in each catchment.…”

Steepland terrain is a characteristic of the Pacific Rim which must be better understood to mitigate and reduce risk associated with the cascade of sediment through short, steep, energetic catchments. The natural laboratory of New Zealand's East Coast ranges provides examples to improve the understanding of linkages between slopes and channels in the upper part of steepland river systems at this critical point in the sediment cascade. These examples illustrate an array of processes contributing abundant sediment in concert with intrinsic and extrinsic controls conditioning catchment connectivity. Once generated from hillslopes, the residence time of alluvium is contingent upon the efficacy of erosion and transfer processes moving sediment along the conveyor. Impacts of point sources of sediment delivery may be long-lived.
