The main focus of this Special Issue of Water is the state-of-the-art and recent research on turbulence and flow–sediment interactions in open-channel flows. Our knowledge of river hydraulics is deepening, thanks to both laboratory/field experiments related to the characteristics of turbulence and their link to erosion, transport, deposition, and local scouring phenomena. Collaboration among engineers, physicists, and other experts is increasing and furnishing new inter-/multidisciplinary perspectives to the research of river hydraulics and fluid mechanics. At the same time, the development of both sophisticated laboratory instrumentation and computing skills is giving rise to excellent experimental–numerical comparative studies. Thus, this Special Issue, with ten papers by researchers from many institutions around the world, aims at offering a modern panoramic view on all the above aspects to the vast audience of river researchers.

Technology: general issues --- wavelet coherency --- Taylor’s frozen turbulence hypothesis --- scale --- hairpin vortex packet --- open channel flow --- bridge pier --- horseshoe vortex --- Physical hydraulic modeling --- quadrant analysis --- Scour and Velocity field --- hydraulics --- turbulent flow --- wall-wake flow --- dunal bedform --- horizontal cylinder --- turbulence structures --- scour --- velocity field --- turbulence --- equilibrium scour depth --- new scaling of scour depth --- ejections --- turbulence interactions --- gravel beds --- sediment transport --- surface and subsurface flows --- river hydrodynamics --- ADCP --- bedforms morphology --- river confluence --- Amazon River --- Yeongsan estuary --- freshwater discharge --- two-layer circulation --- Reynolds stress --- bottom turbulence --- suspended sediment concentration --- sediment kinematics --- entrainment --- disentrainment --- anisotropy --- rigid vegetation --- sediments --- local scouring --- erosion --- transport --- deposition --- open-channel flows --- laboratory experiments

Flooding is widely recognized as a global threat, due to the extent and magnitude of damage it causes around the world each year. Reducing flood risk and improving flood resilience are two closely related aspects of flood management. This book presents the latest advances in flood risk and resilience management on the following themes: hazard and risk analysis, flood behaviour analysis, assessment frameworks and metrics and intervention strategies. It can help the reader to understand the current challenges in flood management and the development of sustainable flood management interventions to reduce the social, economic and environmental consequences from flooding.

River discharge is a fundamental hydrologic quantity that summarizes how a watershed transforms the input of precipitation into output as channelized streamflow. Accurate discharge measurements are critical for a range of applications including water supply, navigation, recreation, management of in-stream habitat, and the prediction and monitoring of floods and droughts. However, the traditional stream gage networks that provide such data are sparse and declining. Remote sensing represents an appealing alternative for obtaining streamflow information. Potential advantages include greater efficiency, expanded coverage, increased measurement frequency, lower cost and reduced risk to field personnel. In addition, remote sensing provides opportunities to examine long river segments with continuous coverage and high spatial resolution. To realize these benefits, research must focus on the remote measurement of flow velocity, channel geometry and their product: river discharge. This Special Issue fostered the development of novel methods for retrieving discharge and its components, and thus stimulated progress toward an operational capacity for streamflow monitoring. The papers herein address all aspects of the remote measurement of streamflow—estimation of flow velocity, bathymetry (water depth), and discharge—from various types of remotely sensed data acquired from a range of platforms: manned and unmanned aircraft, satellites, and ground-based non-contact sensors.
