Erosion dynamics in semiarid environments is defined by high magnitude, low frequency rainfalls that produce runoff with high sediment concentration. Check dams are widely used in this environment as a sedimentation mitigation technique, however their impact on overall watershed sediment balance is not well known. In 2008 a total of 37 loose rock semipermeable check dams were installed on two small (4 and 3.1 ha [9.8 and 7.6 ac]) watersheds located on the alluvial fan of the Santa Rita…

Sediment Yield in Dam-Controlled Watersheds in the Pisha Sandstone Region on the Northern Loess Plateau, China

Soil erosion has become the dominant environmental issue endangering sustainable development in agriculture and the ecosystem on the Loess Plateau. Determination of watershed soil erosion rates and

Comparing the Hydrological Response of Forested Headwaters (Unregulated and Regulated with Check Dams) under Mediterranean Semi-Arid Conditions

This study has evaluated the runoff and erosion rates in torrents of Southern Italy, two forested headwaters with very similar climatic, hydrological and geomorphological characteristics; in one

Analysis of methods to determine the sediment retained by check dams and to estimate erosion rates in badlands

This study aims to compare five frequently used methods to evaluate how they estimate total sediment yield (TSY) at two locations in Central Spain and concludes that the determination of TSY rates depends on the chosen method and four related variables: check dam length, check dam height, wedge length and check dam drainage area.



Long‐term runoff and sediment yields from small semiarid watersheds in southern Arizona

This study presents analysis of 34 years of precipitation, runoff, and sediment data collected from eight small (1.1–4.0 ha) semiarid rangeland watersheds in southern Arizona, USA. Average annual

Evaluation of the SWAT Model for Assessing Sediment Control Structures in a Small Watershed in India

Stormwater runoff is a major pathway for transporting sediment and other nonpoint-source pollutants from watersheds to stream systems and other surface water bodies. In this study, the Soil and Water

Short-term soil moisture response to low-tech erosion control structures in a semiarid rangeland

Sediment yields from unit‐source semiarid watersheds at Walnut Gulch

This study reports sediment yields from seven small (0.18–5.42 ha) watersheds in Southern Arizona measured from 1995 to 2005. Sediment concentrations and total event sediment yields were related to

Measured Sediment Yield Rates From Semiarid Rangeland Watersheds

Abstract Data describing long-term sediment yield rates on semiarid rangeland watersheds are relatively rare. To augment existing data and gain a better understanding of the controlling variables,

The effectiveness of loose rock check dams for gully control in Tigray, northern Ethiopia

Abstract. Over the last two decades, large gully control programmes have been established in Ethiopia. Based on detailed observations and measurements of 400 check dams in the highlands near Hagere

Low erosion rates measured for steep, sparsely vegetated catchments in southeast Spain

Precipitation-runoff relations for very small semiarid rangeland watersheds

Simple linear regression models for predicting total volume of runoff, peak rate of runoff, duration of runoff, and hydrograph lag-time were developed using three years of data from four small (0.56
