“…An index of soil detachability (k) has been considered another main calibrating parameter for sediment modeling and its range is highly related to soil texture. The theoretical range of values for soil detachability index is 0.01 to 10 g j −1 , where maximum values for sand and minimum values for clay (Gumiere et al, 2009;Morgan et al, 1998;Morgan, 2001). …”

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.

“…In this study we ran an enhanced version, the Modified-RMMF-2014 model, of the Modified-RMMF model proposed by López-Vicente and Navas (2010) from the basis of the original Revised Morgan, Morgan and Finney (RMMF) model (Morgan, 2001). The effect of the effective volume of the soil, the processes of cumulative overland flow and the maximum surface storage capacity were added.…”

“…An enhanced version of the Modified-RMMF (Modified Revised Morgan, Morgan and Finney;Morgan, 2001;López-Vicente and Navas, 2010) model of soil erosion and the IC (Index of Connectivity; Borselli et al, 2008) model of sediment connectivity are selected. The RMMF model has been applied in many plots and catchments around the world in studies of soil erosion (e.g.…”

ABSTRACT. The study and quantification of soil redistribution is a complex and difficult task and even a non-solved question at catchment scale both in field and numerical simulation studies. In this study we tackle this topic by coupling two different predicting models and a sound field-based dataset to assess the potential soil redistribution in a Mediterranean rain-fed agricultural and mountainous catchment (La Reina gully catchment, Cinco Villas region, NE Spain): the enhanced Modified-RMMF-2014 version of the "Modified Revised Morgan, Morgan and Finney" model (Morgan, 2001;López-Vicente and Navas, 2010)
