Veneered surfaces, roofs of buildings, streets and the like in urban areas as a barrier against the infiltration of rainwater into the soil and groundwater recharge.They cause more of rainfall to surface runoff and floodsto be converted. Combined method influence, storage and transmission of Atlantis, as the most urban runoff management approach, including implementation of a network of underground ducts, using Atlantis materials and execution of drainage layers on it and store water collected from the network. In this way, the possibility of penetration, transfer and storage provided and benefit levels increased urban streets as well as the transfer and accumulation of contamination is prevented. Town sajadieh located in the lower elevations of the highway and besat shahrzad and street in the south and west causes waterlogging town streets in the rain times. The present study has a descriptive, analytical approach and to investigate the role drainage plate networks, channel and ecological reservoir as the new approach in connection with control and management of surface runoff in town sajadieh Tehran.

to evaluate the different levels of silicon with the selective of wheat herbicides on control of wild oat, yield and yield components of wheat, was conducted a factorial experiment base on completed block randomized design with three replications in the city Eghlid in crop year 1393.The first factor consisted of seven treatments herbicide application topic , Puma super, Atlantiha, Aperous, Suffix , weedy and weed control, and the second factor has two levels of silicon (application and non-application). The results of dry weight wild oats showed that in terms of silicon utilization increased and were significantly different than the non-application of silicon. The height of dry weight wild oats was related to topic and pumasuper herbicides that in control wild oats weren’t succeeded. Herbicides Atlantis and Suffix herbicides had the height control of wild oats. The results of yield and components yield also showed that the use of silicon in herbicides Topic and Puma super were lead to reduction characteristics. In the case of herbicides Atlantis and Pumasuper in terms of the non-application of silica reduction yield and components yields were observed due to phytotoxicity the effects of herbicides on wheat plants. Silicon is used in treatments of herbicides Aperous and atlantis grain yield were significantly increased. The results showed that the silicon leads to reduce the phytotoxicity of herbicides aperous and Atlantis in weather condition Eghlid.

An experiment was conducted to evaluate efficiency of application time of dual purpose herbicides and mixing herbicides on weeds control and growth, physiological, yield and components yield of wheat based on randomized complete block design with three replications in research farm of Gonbad Kavous University in 2014-2015 growing season. Treatments included Total (sulfosulfuron+metsulfuron-methyl), atlantis (idosulfuron+ mesosulfuron+ Mefenpyer-diethyl), Othello (mesosulfuron+ iodosulfuron+ diflufenican+ mefenpyr-diethy), Apirous (sulfosulfuron), Granstar (tribeneron methyl)+Topic (clodinafoppropargyl) in two application times such as primary tillage and primary booting. Treatment of without application of herbicides and hand weeding in two studied times also were used as control. Results showed that aplication of dual purpose herbicides and Granstar +Topic along hand weeding in different consuming times had significant difference on traits such as leaf area, spikes number per m2, number of seeds per spike, seed yield, biological yield, harvest index, chlorophyll a, b and prolin content (p<0.01). On the basis of results, in the most cases herbicides applications and hand weeding in primary tillage time increased effeiciency of them as compared to primary booting.
