“…Mean annual sediment yield can be calculated from the total volume of sediment retained behind check dams, as done by McManus and Duck (1985), Van den Wall Blake (1986), Neil and Mazari (1993), Foster and Walling (1994), White et al (1996), Romero-Díaz et al (2007), Boix-Fayos et al (2008), Sougnez et al (2011) and Bellin et al (2011). Other authors also used this total volume to calibrate or validate mathematical models (e.g.…”

“…This large number of small reservoirs in the world is a high potential source of information for sediment yield assessment and modelling. Some examples of sediment yield studies based on sedimentation volumes in small reservoirs include McManus and Duck (1985), Van den Wall Blake (1986), Neil and Mazari (1993), Foster and Walling (1994), White et al (1996), Romero-Díaz et al (2007), Boix-Fayos et al (2008), Sougnez et al (2011) and Bellin et al (2011). Verstraeten and Poesen (2002) calculated the error on sediment yield estimation for 21 catchments located in central Belgium using small reservoir deposits and concluded that this is a suitable methodology for medium-sized catchments (10 1 -10 4 km 2 ) and for midterm sediment yield estimations (10 0 -10 2 yr).…”

Abstract. Soil loss and sediment transport in Mediterranean areas are driven by complex non-linear processes which have been only partially understood. Distributed models can be very helpful tools for understanding the catchment-scale phenomena which lead to soil erosion and sediment transport. In this study, a modelling approach is proposed to reproduce and evaluate erosion and sediment yield processes in a Mediterranean catchment (Rambla del Poyo, Valencia, Spain). Due to the lack of sediment transport records for model calibration and validation, a detailed description of the alluvial stratigraphy infilling a check dam that drains a 12.9 km 2 sub-catchment was used as indirect information of sediment yield data. These dam infill sediments showed evidences of at least 15 depositional events (floods) over the time period 1990-2009. The TETIS model, a distributed conceptual hydrological and sediment model, was coupled to the Sediment Trap Efficiency for Small Ponds (STEP) model for reproducing reservoir retention, and it was calibrated and validated using the sedimentation volume estimated for the depositional units associated with discrete runoff events. The results show relatively low net erosion rates compared to other Mediterranean catchments (0.136 Mg ha −1 yr −1 ), probably due to the extensive outcrops of limestone bedrock, thin soils and rather homogeneous vegetation cover. The simulated sediment production and transport rates offer model satisfactory results, further supported by in-site palaeohydrological evidences and spatial validation using additional check dams, showing the great potential of the presented data assimilation methodology for the quantitative analysis of sediment dynamics in ungauged Mediterranean basins.

“…It was found that ANN model results are better than conventional empirical methods but inferior to GP. Various investigators (Neil and Mazari 1993;Verstraeten and Poesen 1999) have concluded that sediment trap efficiency is an important parameter to assess sediment yield when sediment deposits in reservoirs. If trap-efficiency is not accounted for in such studies, sediment yield will be underestimated.…”

Sedimentation is an important parameter to assess the life of a reservoir. Seventy-eight years ago, Cook was the first to identify mathematically, the three major factors affecting soil erosion in the catchment of a reservoir. As sedimentation is dependent on sediment yield and sediment yield depends on soil erosion, it is required to predict all three parameters to estimate the life of a reservoir. Since then many researchers carried their research dealing with soil erosion, sediment yield and sedimentation in various reservoirs for its practical significance. The aim of this article is to present a comprehensive state-of-the-art review of the important investigations on soil erosion, sediment yield and sedimentation in various reservoirs highlighting the governing mathematical background of these problems. 198 references are included in this review paper.

“…Sediment yield however can be monitored by using measuring sediment deposition rates in lakes, reservoirs or small ponds (e.g. Van den Wall Bake, 1986;Neil and Mazari, 1993;McManus and Duck, 1985;Foster, 1995;White et al, 1996;Verstreaten andPoesen, 1999, 2001c). In many of this reservoir, sediment deposition can be observed.…”

Sediment deposition in reservoirs is a serious off-site consequence of soil erosion in Semnan Province, Iran. So far insufficient and less reliable sediment yield data have been collected for these regions. The large number of available sediment deposition rates in reservoirs makes the use of reservoir sediments very attractive for regional-scale studies of sediment delivery. This paper however discusses a methodology combination of both source fingerprinting technique and reservoir sediment survey to provide reliable data on sediment yields of geological formation for two small catchments, Iran. The study first assessed the volume and mass of deposited sediment in reservoirs. Secondary a fingerprinting technique have been used to identify the contribution and then specific sediment yield of each geological formation to reservoir sediment. Results indicate that there is some variation in specific sediment yield (SSY) among geological formations in two catchments: i.e. 10.31 t ha-1 year-1 to 0.41 t ha -1 year -1 and emphasize the importance of Quaternary units and Upper Red formations as the dominant surface source within two catchments. This is the important finding to support design and implementation of sediment control strategies in these catchments.
