OVERLAND FLOW ANALYSIS USING TIME SERIES OF SUAS-DERIVED ELEVATION MODELS [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
With the advent of the innovative techniques for generating high temporal and spatial resolution terrain models from Unmanned Aerial Systems (UAS) imagery, it has become possible to precisely map overland flow patterns.

Assessment of frequency and areal extent of overland flow generation in a forested mountain catchment

open access: yesSoil and Water Research, 2011
Short time rainfall and throughfall measurements in the period May-October 2009, and the calculated saturated hydraulic conductivities of soils and isotopic hydrograph separations in August 2009 were used to estimate the frequency of the infiltration ...

Hydrological heterogeneity in Mediterranean reclaimed slopes: runoff and sediment yield at the patch and slope scales along a gradient of overland flow [PDF]

open access: yesHydrology and Earth System Sciences, 2012
Hydrological heterogeneity is recognized as a fundamental ecosystem attribute in drylands controlling the flux of water and energy through landscapes. Therefore, mosaics of runoff and sediment source patches and sinks are frequently identified in these ...

Soil roughness and overland flow [PDF]

open access: yesAgronomie, 2000
Rugosité du sol et écoulement sur le terrain. La rugosité de la surface du sol affecte le stockage de l'eau dans les dépressions de la surface, son infiltration et la vitesse ainsi que l'organisation de l'écoulement sur le terrain. Cet article tente de donner une vue d'ensemble de nos connaissances actuelles sur les effets de la rugosité sur le ...

Two-dimensional (2D) numerical modelling of rainfall induced overland flow, infiltration and soil erosion: comparison with laboratory rainfall-runoff simulations on a two-directional slope soil flume

open access: yesJournal of Hydrology and Hydromechanics, 2021
This paper presents a two-dimensional (2D) numerical model of soil erosion and sediment transport resulting from rainfall induced overland flow. It is a spatial and temporal dynamic model combining physical and empirical laws and comprises: i) An ...

Influence of Vegetation Types on the Hydrodynamic Characteristics of Overland Flow on Slopes in Riparian Zone

open access: yesShuitu baochi yanjiu, 2023
In order to study the influence of riparian zone vegetation types on the hydrodynamic characteristics of the overland flow, through the field water discharge scour experiments simple runoff plot, the variations of hydrodynamic parameters of overland flow

Field experiment investigation into the spatial variability of overland flow velocity and soil erosion

open access: yesShui kexue jinzhan, 2015
The spatial variability of overland flow velocity and soil erosion,and their relationship under different discharges,were investigated using a field runoff plot combined with the erosion pins. There exists a positive correlation between flow velocity and

Use of terraces to mitigate the impacts of overland flow and erosion on a catchment

open access: yesPlant, Soil and Environment, 2016
The paper presents the impact of a historical system of terraces constructed centuries ago to mitigate the effect of a steep slope on overland flow. Systems of this type were constructed in past centuries by land owners, who then ploughed the land and ...
