There is much policy interest in the possible linkages that might exist between land use and downstream fluvial flood risk. On one hand, this position sustained by observations from plot- field-scale studies suggest management does affect runoff. other, upscaling these effects to show land-management activities impact upon risk at larger catchment scales has proved be elusive. This review considers reasons for why problematic. We argue that, rather than it reflecting methodological...
Abstract. Emergency responders often have to operate and respond emergency situations during dynamic weather conditions, including floods. This paper demonstrates a novel method using existing tools datasets evaluate responder accessibility flood events within the city of Leicester, UK. Accessibility was quantified 8 10 min legislative targets for provision ambulance fire rescue services respectively under "normal" no-flood as well scenarios various magnitudes (1 in 20-year, 1 100-year...
Abstract Hydrograph convolution is a product of tributary inputs from across the watershed. The time‐space distribution precipitation, biophysical processes that control conversion precipitation to runoff and channel flow conveyance processes, are heterogeneous different areas respond rainfall in ways. We take subwatershed approach this account for magnitude, relative timing, sequencing. hypothesize as scale watershed increases so we may start see systematic differences hydrological...
Abstract Urban flooding is one of the major issues in many parts world, and its management often challenging. One challenges highlighted by hydrology related communities need for more open data monitoring floods space time. In this paper, we present development phases experiments an Internet Things (IoT)-based wireless sensor network hydrometeorological collection flood urban area Colima-Villa de Álvarez Mexico. The designed to collect fluvial water level, soil moisture weather parameters...
Abstract Research has found that both flood magnitude and frequency in the UK may have increased over last five decades. However, evaluating whether or not this is a systematic trend difficult because of lack longer records. Here we compile consider an extreme record extends back to 1770. Since 1770, there been 137 recorded floods. period, unidirectional rising risk time. Instead, are clear flood‐rich flood‐poor periods. Three main periods were identified: 1873–1904, 1923–1933, 1994 onwards....
Leaky dams, particularly those constructed from large woody material, are increasingly implemented in headwater streams to reduce runoff rates by enhancing channel roughness, slowing flow velocities, and creating temporary water storage during high-flow events desynchronise flood peaks within catchments. Despite significant progress modelling the hydraulic hydrological effects of leaky dams through flume experiments field studies, design guidance for construction still needs be improved. A...
Abstract Dissolved oxygen (DO) plays a critical role in the development of juvenile stages benthic spawning fish and salmonids particular. Factors influencing DO regime within gravels include accumulation fine sediment, penetration groundwater or surface water into gravels, thermal regime, consumption by sediment its associated organic fractions. In this field study, we quantify an artificial salmon redd at high temporal resolution. The environment is shown to be complex, with large...
Determining the respective attribution proportions of climate change and land use to streamflow variations in river systems is increasing interest researchers practitioners tasked with managing basins. This paper proposes an extension established techniques attributing relative (CC) (LUC) drivers by instead considering these as distributed through a probability density function (pdf), rather than point value. The novel method demonstrated for River Tweed UK. Results are determined flow,...
Abstract Globally, salmon populations are under pressure and in those where numbers severely depleted, density independent factors such as the accumulation of fine sediment subsequent mortality incubating embryos critical their conservation. Although progress has been made identifying processes by which can lead to embryo mortality, this focussed on physical blockage gravel pores. This paper presents new knowledge role sediment‐associated organic matter controlling supply dissolved oxygen...
Abstract Tropical cyclone (TC) landfall is often accompanied by storm surges, strong winds, and heavy rain that cause destructive flash floods, especially in mountainous regions. However, there limited understanding of the contribution TCs to major flood events, Western Mexico. In this study, we assess annual rainfall, extreme rainfall stream flow region Colima, one most TC‐exposed areas The top 1% daily flow, maximum highest 20 events from 1970 2015 are examined for their association TCs....
Abstract. Salmonids clean river bed gravels to lay their eggs. However, during the incubation period fine sediment infiltrates bed. This has been found limit success of salmonid spawning, as reduces gravel permeability resulting in intra-gravel flow velocities and O2 concentrations decreasing. The spawning is therefore a function coincidence delivery development presence also exerts sub-lethal effects on rate egg with negative feedback slowing extending process meaning eggs are for longer...

The implementation of Natural Flood Management (NFM) measures theoretically provides an opportunity to build resilience into flood risk management systems in a way that incorporates sustainable practices and holistic the landscape. However, there remains lack clear understanding these solutions, practice this can hinder uptake NFM;  there is need expand emerging evidence base order quantify demonstrate their effectiveness range catchment storm event scenarios. This study focuses on...

Rural land management impacts on catchment scale flood riskThis thesis examines the relationship between rural and downstream risk.The recent increase in frequency magnitude has been hypothesised to have caused by either climate change or management.The theoretical basis for why these factors might risk is well known, but showing their impact remains a challenge.Field studies found that changing practices does affect local runoff streamflow.Upscaling effects continues be problematic, both...
