Abstract Satellite altimetry is routinely used to provide levels for oceans or large inland water bodies from space. By utilizing retracking schemes specially designed waters, meaningful river stages can also be recovered when standard techniques fail. Utilizing retracked waveforms ERS‐2 and ENVISAT along the Mekong, comparisons against observed stage measurements show that altimetric have a root mean square error (RMSE) of 0·44–0·65 m 0·46–0·76 ERS‐2. For many applications, however,...
Despite there being well-established meteorological and hydrometric monitoring networks in the UK, many smaller catchments remain ungauged. This leaves a challenge for characterisation, modelling, forecasting management activities. Here we demonstrate value of community-based ('citizen science') observations modelling understanding catchment response as contribution to science. The scheme implemented within 42 km2 Haltwhistle Burn catchment, tributary River Tyne northeast England, has...
Abstract Achieving urban flood resilience at local, regional and national levels requires a transformative change in planning, design implementation of water systems. Flood risk, wastewater stormwater management should be re-envisaged transformed to: ensure satisfactory service delivery under flood, normal drought conditions, enhance extend the useful lives ageing grey assets by supplementing them with multi-functional Blue-Green infrastructure. The aim multidisciplinary Urban Resilience...
Rainfall-runoff modeling is highly uncertain for a number of different reasons. Hydrological processes are quite complex, and their simplifications in the models lead to inaccuracies. Model parameters themselves uncertain—physical because observations conceptual due limited identifiability. Furthermore, main model input—precipitation available high spatio-temporal variability. The quantification output uncertainty essential use. Most approaches used rainfall-runoff assign parameters. In this...
A methodology is developed to estimate daily river discharge at an ungauged site using remote sensing data. Use made of ERS-2 and ENVISAT satellite altimetry provide a time series channel stage levels longitudinal slope Landsat imagery range widths over 50 km reach river. The data are substituted into the Bjerklie et al. (2003) equation, which based on Manning's resistance equation has been global database hydraulic information measurements. Our applied three locations Mekong Ob Rivers...
Abstract. The Yangtze River basin is home to more than 400 million people and contributes nearly half of China's food production. Therefore, planning for climate change impacts on water resource discharges essential. We used a physically based distributed hydrological model, Shetran, simulate discharge in the just below Three Gorges Dam at Yichang (1 007 200 km2), obtaining an excellent match between simulated measured daily discharge, with Nash–Sutcliffe efficiencies 0.95 calibration period...
Abstract An integrated field and modelling study was carried out on the 35‐ha La Reina catchment, Chile, to test hypothesis that effect of forest cover flood peaks becomes less important as size hydrological event increases. Meteorological discharge data were measured at catchment before after pine plantation covered 80% area logged. Analysis response provides support for but is not conclusive. Therefore, using 1000 years generated rainfall representative current conditions forested logged...
Abstract Ponds and the adjacent green spaces are an important part of urban blue-green Infrastructure (BGI) contribute to a number ecosystem services, including alleviation flood risk, amelioration climatic fluctuations, improvement runoff water quality, as well biodiversity amenity values. Multiple benefits associated with ponds have only recently started be appreciated, examples in-depth interdisciplinary insights remain rare. This paper gives account services provided by Blackford Pond,...
The use of physically-based spatially-distributed models to solve problems in hydrology has been limited by their intensive data and setup time requirements. We have therefore created a system that enables the automatic robust, SHETRAN model for any catchment, gauged or ungauged, Great Britain. National-scale datasets topography, soil, landuse, geology climate collated, processed stored allow rapid retrieval configuration catchment with minimal user-intervention. These maps can be easily...
Abstract The SHETRAN physically based, spatially distributed model is used to investigate the scaling relationship linking specific sediment yield river basin area, for two contrasting topographies of upland and more homogeneous terrain as a function source, land use rainfall distribution. Modelling enables effects controls be examined on systematic basis, while avoiding difficulties associated with field data (which include limited data, lack measurements nested basins inability isolate...
Main international rivers of Iberia (SW Europe): Douro, Tagus and Guadiana. has long suffered from water scarcity which will worsen with projected reductions in rainfall increases temperature. Nonetheless, there been almost no research concerning the future discharges these rivers. We examine an ensemble climate model projections CMIP5 RCP 8.5 use two downscaling methods to produce a range changes discharge using physically-based, spatially-distributed hydrological (SHETRAN) for historical...

Abstract Bank erosion can contribute a significant portion of the sediment budget within temperate catchments, yet few catchment scale models include an explicit representation bank processes. Furthermore, is often simplistic resulting in inability to capture realistic spatial and temporal variability simulated erosion. In this study, component model SHETRAN developed incorporate key factors influencing spatio‐temporal rate erosion, due effects channel sinuosity vegetation. The applied Eden...
Earthworks such as embankments and cuttings are integral to road rail networks but can be prone instability, necessitating rigorous continual monitoring. To date, the potential of remote sensing for earthwork hazard assessment has been largely overlooked. However, techniques airborne laser scanning (ALS) now ripe addressing these challenges. This research presents development a novel strategy, combining high-resolution with numerical modeling approach. The was implemented at railway test...
