“…Ran et al (2008) showed that check dams are the most effective soil conservation measures to rapidly reduce the amount of coarse sediment (grain size d ≥ 0.05 mm) entering the major rivers. Hassanli et al (2009) found that the portion of clay and silt trapped by porous check dams decreased from the downstream sections toward the upstream sections. The check dams located at the far downstream sections were more efficient at trapping fine sediment than those located at the middle sections and the upstream sections.…”

A B S T R A C TCheck dams can be used as a source of information for studies on sediment characteristics and soil particle erodibility. In this study, sediment yield and grain size distribution (GSD) were measured in twenty small catchments draining into a rock check dam in NW Iran for different runoffs during 2010-2011. Significant correlations were found between sediment yield and slope steepness, vegetation cover and soil erodibility factor (K) of the catchments. The erodibility of soil particles was determined using the comparison of GSD between sediment and original soil. Clay was the most erodible soil particle which showed 2.05 times more percentage in sediment than the original soil. The erodibility of soil particles were strongly affected by the rainfall erosivity (EI 30 ). Check dams showed more effectiveness in trapping coarse particles (sand and gravel). The effectiveness of check dams in trapping coarse particles enhanced with increase in the remaining capacity of check dams.

“…Hassanli et al (2009) stated that grain size distribution of sediments deposited behind check dams depends on the type of the sediments transported and the performance of the check dams in trapping the sediments. In this study, the check dam is a solid dam where both water and sediments are trapped.…”

Check dam sediments document the process of soil erosion for a watershed. The main objectives of this research are as follows: first, to determine whether the sediments trapped in check dams can provide useful information about local erosion and the environment, and second, to obtain the extent to which they can be stratigraphically interpreted and correlated to the land use history of an area controlled by check dams. Particle size and the concentration of 137 Cs in sediments are the indicators used to study the effects of environmental changes on soil erosion in the Loess Plateau, China. A total of 216 soil samples were collected from four sediment profile cores at the Yangjuangou watershed check dam constructed in 1955 and fully silted with sediments by 1965. The results indicated that 137 Cs dating and sediment particle size can characterize the sediment deposition process. Silt makes up more than 50 % of the sediment; both the clay and silt sediment fractions decrease gradually in the upstream direction. The sediment profiles are characterized by three depositional layers. These layers suggest changes in the land use. The top layer showed tillage disturbance, with moderate sediments and new soil mixed from 0 to 20 cm. A transition stage from wetlands (characterized by vegetation such as bulrush) to cropland is inferred from sediments at depths of 20-85 cm. Below 85 cm, sedimentary layering is obvious and there is no tillage disturbance. At the downstream site, A0, the average rate of sediment deposition from 1958 to 1963 was approximately 6,125.4 t year −1 km −2 . Because of their high time resolution, check dam sediments indicate the effects of environmental changes on soil erosion, and they can provide a multiyear record of the soil erosion evolution at the local scale in the middle reaches of the Yellow River.

“…Therefore, check dams are actually multifunctional landscape units that can also trap huge amount of carbon in sediments. They have been used globally across various climate conditions such as the semiarid west Asia and Mediterranean region as well as humid European mountains (Wohl, 2006;Castillo et al, 2007;Hassanli et al, 2009). The carbon retention effects of these units cannot be neglected both for functional appraisal on check dams and their potential impacts on carbon cycling.…”

“…Check dams are manmade hydrological engineering structures built across drainage channels (Zeng et al, 2009). Although usually constructed with objectives of soil erosion control, their functions can be multi-dimensional such as soil and water retention, ground water recharge, water harvesting and supply, gully and slope stabilization, control of debris flow, regulation of river channel morphology, improvement of habitat conditions for vegetation restoration (Heede, 1979;Balooni et al, 2008;deWolfe et al, 2008;Ran et al, 2008;Bombino et al, 2009;Hassanli et al, 2009;Garg et al, 2011). Hence, check dams are actually multi-functional landscape units.…”

a b s t r a c tCheck dams have been widely used globally as human introduced structures for watershed management for various purposes. However, the effects of these structures for carbon retention have been scarcely considered and quantified. This research formulated a simple approach in estimating the carbon retention effects of check dams in Yan'an prefecture of the Loess Plateau region of China based on check dam inventory data and benefit transfer approach. Results indicated that the large and medium sized check dams had retained about 42.3 million tons of soil organic carbon (SOC) with a high spatial variability. This is a significant amount similar to about 1.48% of the SOC stored in the 0-40 cm soil layer across the whole Loess Plateau or roughly 4% of the estimated carbon emission from fossil fuel in China in 2000. Total volume of check dam is the most important influencing factor for carbon retention effects at both check dam and county-levels. Years after construction is also a significant factor at check dam level. The numbers of check dams and land use as well as topographical factors have impacts on the respect of check dam carbon retention of varied significance at the county-level. The effectiveness of carbon retention decreased from north to south. The results of this research can be used as important decision support for check dam development planning at the local context. This research also revealed the scientific worthiness in quantifying the carbon retention effects concerning the relationships between soil erosion and carbon cycling. On this respect, process-based monitoring and research are urgently in need.
