This paper aims to examine the nature of width, depth and configuration distribution along Kuya River and their temporal directionality of changes. It also pays attention to prepare some simplified indices regarding basin asymmetry, channel asymmetry and river bank stability and to explain the nature of basin and channel asymmetry and river bank stability using those constructed indices. Irregu...

Introduction and methods Marine litter density, distribution potential sources, the impact on canyon seafloor habitats were investigated in Motril, Carchuna Calahonda canyons, located along northern margin of Alboran Sea. During ALSSOMAR-S2S oceanographic survey carried out 2019, floor imagery was collected by a Remotely Operated Vehicle 5 km Motril Canyon, 10 3 together with 41 surficial sedim...

Check dams are used in gullies to prevent vertical downcutting of the thalweg. built as log crib structures common steep creeks prone floods or debris floods. Recent experience with performance check subject flow loadings is less common, those often made from reinforced concrete, steel masonry. This paper summarizes our six a gully at East Gate Landslide, between Revelstoke and Golden, BC, Cana...

Detailed bathymetry data are collected on short reaches and are usually not available for the entire stream network at a regional scale. By using the field data collected for a reach along the Brazos River in Texas, a geographic information system (GIS) framework for describing river channel bathymetry at regional-scale is presented. The framework is based on deriving relationships among differ...

Debris flow erosion into bedrock helps to set the pace of mountain denudation, but there are few empirical observations this process. We studied effects debris flows on using Structure-From-Motion photogrammetry and multiple real-time monitoring measurements. found that distribution across channel cross-section could be generalized as an exponentially decreasing function height above thalweg. U...

INTRODUCTION The objective of this study is to provide a synthesis of the pertinent design criteria for submerged bendway weirs. The technical paper is an extension of previous research conducted by the National Center for Computational Hydroscience and Engineering (NCCHE) at the University of Mississippi on the hydrodynamic effects on flow characteristics and effectiveness of submerged bendway...

Habitat evaluation of wadeable streams based on accepted protocols provides a rapid and widely used adjunct to biological assessment. However, little effort has been devoted to habitat evaluation in non-wadeable rivers, where it is likely that protocols will differ and field logistics will be more challenging. We developed and tested a non-wadeable habitat index (NWHI) for rivers of Michigan, w...

A surface network is a topological data structure formed by set of thalwegs and ridges on digital terrain model. Its computation relies the detection saddles terrain. Hence, methods must guarantee enough are detected but also that no improper conflicts between created, leading to an inconsistent network. This paper presents new approach maximizes number ensures this consistency for high-resolut...

New methods allow the direct computation of flood inundation maps from lidar data, independently discharge estimates, hydraulic analysis, or defined cross sections. One method projects interpolated profile measured levels onto surrounding topography, creating a smooth surface that is entirely based on data and geometrical relationships. A second computes for any simple function relates water to...
