“…This fact was probably due to the occurrence of the free inter-row space as a result of the free growing crop, and due to the water drip from leaves in the centre of the inter-row. The effect of the water drip from leaves on the water concentration in the centre of inter-rows and on the increasing splash erosion is pointed out by Brandt (1989), Bruckler et al (2004), and Morgan (2005).…”

Soil & Water Res., 12: 39−50.Line width is one of the major factors affecting arable soil erosion. The aim of the study was to assess the effects of different row spacing on splash erosion and throughfall in maize crops. Field measurements of the throughfall (P th , mm) and splash erosion (MSR, g/m 2 ) were carried out in silage maize crops (

“…The model has been developed by integrating soil erosion-sediment transport processes with the distributed hydrological model developed by Dutta et al (2000). Hillslope sediment dynamics has been represented by appropriate physical equations selected after a comprehensive review of the existing literature (e.g., Torri et al, 1987;Brandt, 1989Brandt, , 1990Smith et al, 1995;Morgan et al, 1998;Jain et al, 2005).

Abstract. Modeling of sediment dynamics for developing best management practices of reducing soil erosion and of sediment control has become essential for sustainable management of watersheds. Precise estimation of sediment dynamics is very important since soils are a major component of enormous environmental processes and sediment transport controls lake and river pollution extensively. Different hydrological processes govern sediment dynamics in a river basin, which are highly variable in spatial and temporal scales. This paper presents a process-based distributed modeling approach for analysis of sediment dynamics at river basin scale by integrating sediment processes (soil erosion, sediment transport and deposition) with an existing processbased distributed hydrological model. In this modeling approach, the watershed is divided into an array of homogeneous grids to capture the catchment spatial heterogeneity. Hillslope and river sediment dynamic processes have been modeled separately and linked to each other consistently. Water flow and sediment transport at different land grids and river nodes are modeled using one dimensional kinematic wave approximation of Saint-Venant equations. The mechanics of sediment dynamics are integrated into the model using representative physical equations after a comprehensive review. The model has been tested on river basins in two different hydro climatic areas, the Abukuma River Basin, Japan and Latrobe River Basin, Australia. Sediment transport and deposition are modeled using Govers transport capacity equation. All spatial datasets, such as, Digital Elevation Model (DEM), land use and soil classification data, etc., have been prepared using raster "Geographic Information System (GIS)" tools. The results of relevant statistical Correspondence to: M. A. Kabir (aynul.kabir@monash.edu) checks (Nash-Sutcliffe efficiency and R−squared value) indicate that the model simulates basin hydrology and its associated sediment dynamics reasonably well. This paper presents the model including descriptions of the various components and the results of its application on two case study areas.

“…To estimate the interception store, the equations of Merriam (1973) and Aston (1979) are adopted in EUROSEM and LISEM, respectively. Thereafter, the KE (Jm 2 mm 1 ) of direct throughfall is calculated using the formula of Brandt (1989) and the KE of leaf drainage is estimated using the formula of Brandt (1990). Both values of KE are summed and finally used to estimate the detachment induced by rainsplash under the canopy.…”

“…Second, the drop size distribution (DSD) and terminal velocity of throughfall are changed due to scattering, dripping and the height of lowest trunk. Although the amount of throughfall generally decreases, the KE of throughfall increases, resulting in greater interrill erosion under the canopy than on an open site (Mosley, 1982;Brandt, 1989Brandt, , 1990Nanko et al, 2004Nanko et al, , 2008.…”

Abstract:Soil loss plots on open and under canopy sites were installed to study the effect of the canopy on interrill erosion. The erosion rate under the canopy was smaller than that on an open site, and it was highly correlated with the maximum rainfall intensity for 3 hour and total rainfall, independent of the slope angle. The throughfall rate showed a relatively continuous value under high rainfall intensity conditions, although varied with rainfall intensity. When the throughfall rate was initiated at a relatively continuous value, the rainfall intensity was very similar to the threshold of rainfall intensity for erosion under a canopy. These results imply that the canopy storage had been changed due to the rainfall intensity, and this change affected the interrill erosion under the canopy. These results will contribute to the development of an erosion prediction model under a forest canopy.
