Journal of Hydrologic Engineering, 2005 Roll waves are frequently observed in overland flow, especially in rill flow, which has an important effect on the development of soil erosion. Using one-dimensional St. Venant equations, this paper investigates the dynamics of periodic roll waves based on Dressler’s and Brock’s work.

Variability in the Mobilization of Sediment and Phosphorus across 13 European Soils. [PDF]
, 2009 The objectives of this study were to examine the variability in mobilization and transport of primary particles and associated total phosphorus (TP) in sediments eroded by overland flow from 13 European arable soils and to consider the empirical support ...

Hydrology Research, 1981 Kinematic wave theory is utilized to investigate diverging overland flow which does not appear to have been previously investigated in watershed hydrology. This paper is the first in a sequel of two. It developes analytical solutions for a diverging geometry for two cases: (1) when infiltration is considered through rainfall-excess, and (2) when ...

Overland Flow and the Runon Process
, 2012 The processes of infiltration and overland flow over natural surfaces have important applications in surface runoff computations and transport of associated contaminants. Since natural fields exhibit spatially heterogeneous infiltration properties, water from upstream saturated areas may infiltrate into downstream regions where moisture deficit has not

Two-Dimensional Kinematic Wave Model of Overland-Flow [PDF]
, 2004 A two-dimensional kinematic wave model was developed for simulating runoff generation and flow concentration on an experimental infiltrating hillslope receiving artificial rainfall. Experimental observations on runoff generation and flow concentration on

Tracing near-surface runoff in a pre-Alpine headwater catchment [PDF]
Hydrology and Earth System SciencesNear-surface flow pathways (i.e., overland flow and topsoil interflow) play a crucial role in runoff generation and solute transport in steep humid catchments with low-permeability gleysols but remain understudied.

Assessing the quality of digital elevation models obtained from mini unmanned aerial vehicles for overland flow modelling in urban areas [PDF]
Hydrology and Earth System Sciences, 2016 Precise and detailed digital elevation models (DEMs) are essential to accurately predict overland flow in urban areas. Unfortunately, traditional sources of DEM, such as airplane light detection and ranging (lidar) DEMs and point and contour maps, remain

Microrelief-Controlled Overland Flow Generation: Laboratory and Field Experiments
Applied and Environmental Soil Science, 2015 Surface microrelief affects overland flow generation and the related hydrologic processes. However, such influences vary depending on other factors such as rainfall characteristics, soil properties, and initial soil moisture conditions.
