Abstract
Recent advances in river instrumentation, including acoustic and remote sensing methods for measuring river hydrodynamics and morphology, are revolutionizing our capabilities to understand, describe and model river systems. The instrument development outpaces their thorough evaluation and assimilation such that a rigorous review is a daunting task. While not exhaustive, the present paper focuses on the new generation of acoustic and remote sensing methods and their synergy in providing new insights into the river hydrodynamic and morphologic macro‐characteristics. These instruments can quickly and efficiently provide detailed multi‐dimensional measurements that uniquely enable investigation of complex river processes that are related to critical issues such as river hydrodynamics, sediment transport, habitat availability and stream ecology. The paper reviews modern instruments including Acoustic Doppler Velocimeter (ADV), Acoustic Doppler Current Profiler (ADCP), Large Scale Particle Image Velocimetry (LSPIV), Multibeam Echosounder (MBES) and Airborne Bathymetry LiDAR (ABL). The use of two acoustic methods, namely ADCP and MBES, is then presented for describing multi‐dimensional river hydrodynamics and morphology by using data from three river reaches (Brazos River in Texas, Kissimmee River in Florida and Mississippi River in Iowa) in the United States. ADCP and MBES provide two and three dimensional datasets that have opened the door to many new research opportunities in the past decade. A brief description of these new opportunities along with the challenges that these new datasets bring is also discussed.
