“…Installation of vegetative buffer strips in the irrigated lands of vulnerable semiarid regions can be useful to mitigate the destructive effects of human activities and consequently improve environmental protection. However, it should be considered as an additional approach for contamination control along with other control measures under field conditions in semiarid areas (Campo‐Bescos, Munoz‐Carpena, Kiker, Bodah, & Ullman, ).…”

Soil and water conservation in natural and cultivated areas is a major concern for humankind. However, there are severe problems with degraded hillslopes due to bare soils in northern Iran, which are one of the most important factors driving land degradation processes. Subsequently, soil erosion, pollutant transport, and/or nutrient impoverishment are affecting large territories; therefore, rapid and inexpensive soil conservation measures need to be implemented. The use of vegetative buffer strips could be an effective strategy to reduce pollutant transport as well as soil erosion.Thus, this research aimed to investigate the possible efficiency of two different vegetative buffer strips composed of vetiver-grass (Chrysopogon zizanioides) and native turf-grass (Festuca arundinacea) at reducing runoff and soil losses as well as nitrate transport on a representative degraded hillslope with bare soils in Mazandaran, Iran.Twelve 10 m 2 experimental plots were tested over 1 year using a runoff simulator that produced overland flow that corresponded to the 25-and 100-year return period rainfall events. The plots with bare soils had the highest runoff volumes (30.5 and 55.4 L m −2 ), sediment concentrations (101.2 and 430.6 g L −1 ), and nitrate concentrations (10.4 and 37.6 mg L −1 ). Vetiver was the most useful tool to reduce runoff, soil loss, and nitrate concentration, with values of 13.4 and 28.6 L m −2 , 13.4 and 90.9 g L −1 , and 2.9 and 16.4 mg L −1 , respectively. Of the treatments investigated, vetiver provided the most rapid cover and was the most efficient at preventing soil erosion and nitrate transport directly after plantation.

“…Soil erosion took place at the head and tail ends, while the deposition occurred at the middle of the experimental furrows. Campo‐Bescós et al (2015) investigated the effects of different factors such as slope, soil texture and plant filter on sediment contamination and runoff from irrigated furrows in arid areas. Their results showed that plant filter had the highest impact on pollution and runoff control.…”

The suspension of eroded soil in surface runoff ultimately leads to the transfer of nutrients to land and water resources. Placing soil or straw (as a barrier) inside irrigated furrows in order to reduce water flow velocity, as a traditional local practice, has not been investigated from the environmental point of view. In this research, the effect of micro‐dams (barriers built inside the irrigated furrows, also known as tied ridges or furrow dikes) on the reduction of soil and phosphorus losses was investigated. Field experiments were performed in four consequent irrigation events. Two erosive inflow discharges (0.6 and 0.9 L/s) and two micro‐dam distances (10 and 20 m) were implemented as test treatments. A control treatment, without micro‐dams, was used for comparison purposes. For the discharge of 0.6 L/s, micro‐dams reduced furrow soil loss by 25% and 33% for distances of 20 and 10 m, respectively. For 0.9 L/s, soil loss was reduced by 25% and 59% for distances of 20 and 10 m, respectively. Micro‐dams also reduced dissolved phosphorus losses in runoff water by 13% to 37%, depending on discharge and distance, as compared to the control treatment. Micro‐dams can effectively reduce water, soil and phosphorus losses.

The role of irrigation is very important to increase agricultural production. Utilization of water through a good treatment system for water utilization is implemented effectively and efficiently. Sediment transport in irrigation can shorten the service life of irrigation networks, due to silting and decreasing capacity, making it difficult for water to reach the surface of the rice fields and irrigate rice fields. Various efforts have been made to reduce sediment transport in irrigation canals, one of which is commonly done is the manufacture of Sediment Retention Models (SRM). Nevertheless, the sediments continue to enter the irrigation canal in considerable amounts. So in operation and maintenance it requires a high enough cost for such sediment dredging Given the importance of a sediment-catcher building, special attention needs to be paid to this problem, among others, by creating a sediment-resistant model that has the ability to capture sediment well. In the hope of helping to precipitate sediment so as not to disrupt the function of the channel. The research will be conducted at the Civil Engineering Laboratory of Muhammadiyan University of Makassar. The purpose of the research is to know the nature of the flow that occurs in the sediment catcher building, to know the volume of basic sediment transport with the calculation directly and compare with the formula approach. The results showed that the larger volume of sediment flow velocity tended to narrow, from 0.
