The purpose of this study was investigating the effect of eleven gabion and five masonry dams on trapping eroded particles in the razin watershed located north of Kermanshah township. The frequency of sand particles increased by 40.67 percent and the percentage of gravel, silt and clay particles decreased by 14.37, 56.55 and 69.93 percent in sediments behind the gabion dams as compared to the w...
Erosion on reservoir margins causes losses in the production of energy Hydroelectric Power Plants (HPPs), making it necessary to implement control techniques that ensure reduction sediment deposits inside reservoirs. Among these techniques, geomats (geosynthetic erosion mats) are widely used processes slopes and watercourses. This material protects both short long term, contributing strengtheni...
In this study, a structure that can effectively prevent overtopping caused by abnormal rainfall was installed in deteriorative agricultural reservoir, and seepage characteristics were compared analyzed through model experiments numerical analysis. The experimental conditions observed installing stepped gabion, vertical parapet combination with gabion retaining wall, geomembrane, core on the dam...
The objective of this work was to determine a design for riparian protection infrastructure using gabions in the Peruvian jungle. methodology used an applied, quantitative type, sample is area between kilometers 1,060 and 1,660 Chaupimayo creek, Madre de Dios, Peru. conclusionswere that soil on surface clayey sand (SC) depth silty gravel (GM), micro-basin has 0,365 km2, perimeter 3,03 km. Likew...
Stepped spillways have become a popular method for handling flood releases. The steps increase significantly the rate of energy dissipation taking place on the spillway face and reduce the size of the required downstream energy dissipation basin. The compatibility of stepped spillways with roller compacted concrete (RCC) and gabion construction techniques results in low additional cost for the ...
Coal mine backfilling can effectively prevent large-scale movement of rock formations, not only improving the overall production capacity but also protecting surface from destruction and maintaining original ecological environment. Backfilling extent backfills compactness are two factors determining supporting effect on overburdens in underground coal mines. To make full use aeolian sand as bac...
The stability of roadbed in seismic prone areas is vital for the sustainable economic development regions. gabion structures are one methods road strengthening. Gabion used to avoid damage under loads natural ground slope due earthquake or other reasons. This approach most economical and efficient solutions stabilization slopes, it as a drainage system. Field tests give precise results about ef...
abstract the groines are structures which are use to protected the river bank and to form the water way .the most important problem of groynes is scour at around it that makes breaking and overturning the groynes. because of the less researches at about l-head groynes and open groynes ,this article considers the amount of scour in this type of groynes. so because of this have been used the lace...
