AWBM Simulation in no-available data watersheds of Fars province

M.Abassi-Zadeh, J.Nam-Dorost Page 257

There are diffrent methods for estimating runoff from rainfall in catchments. One ofthis methods is using hydrological models. Hydrological models allow the simulatingrainfall-runoff process in noavailable data watersheds (catchments) with low cost andtime. The AWBM model that developed by Walter Boughton, is one of this kinds ofmodels that can estimate runoff from daily or hourly rainfall. Application of themodel for daily results is using in water supply and for hourly result is using in floodcontrol. in this model storage capacity is divided into three storage parametes (C1, C2, C3). It can estimate the related partial areas (A1, A2, A3) and simulate the runofffrom partial areas using daily rainfall, discharge and evatranspiration with optimizingthe parameters. The objective of this study is to evaluate the performance of the variable sourcearea AWBM model in some Fars province catchments. The analysis was carried outusing data from selected catchments، namely Kol, Maharloo, Zohre and Mond, in Farspronince. The daily rainfall, runoff and evatranspiration selected with about 20 yearsduration. Daily rainfall regionalized with using TPSS method and daily dischargeconverted to spasial discharge. The correlation cofficient between estimated andobserved runoff was evalutated by optimizing the parameters. The results showed thatthe AWBM model, gives acceptable results and have adequate capability fordesigning.

M.R.Asgharipour, M.Rafie Shirvan Page 269

Application of urban refuse compost to agricultural soil could help to solve urbanproblems in large cities caused by increasing production of waste. Refuse compost hasbeen identified as an alternative to fertilizer to increase soil fertility and cropproduction. In this research the capacity of compost made from urban refuse toenhance emergence seedling grown in potting soil was studied. Four treatments wereestablished based on the addition of increasing quantities of composted urban refuseto soil (1:2.5, 1:5, 1:7.5, 1:10 v/v). Physical, physio-chemical and chemical analysesof different mixtures were made. Plant growth, biomass production andmacronutrient, micronutrient and heavy metal contents of plant and soil weredetermined. The addition of compost increased pH, electrical conductivity (EC) ofsubstrates, and macronutrients, micronutrients and heavy metal of plants andsubstrates. The highest germination, growth rate, shoots and roots dry weight wasobtained with the medium prepared by mixing rate of 1:5 compost and soil. Themixture with the most compost (1:2.5) had the lowest germination and growth oftomato seedling.

Daneshmand, A.H.Shirani-Rad, Gh.Noormohamadi, Gh.Zarei J.Daneshian Page 295

In order to determine the effects of water deficit and different nitrogen levels on oilseed, seed protein and relations of them with oil yield and protein yield in rapeseed,two field experiments were conducted using a factorial split-plot in randomizedcomplete block design in 2005 and 2006 growing seasons at Seed and PlantImprovement Institute, karaj. In this study, two cultivars (Zarfam and Modena), threewater regimes (irrigation after 40, 60 and 80 percent depletion of soil water) and fournitrogen levels (0, 75, 150 and 225 Kg/ha) were studied that irrigation and nitrogentreatments were in main plots and cultivars were in sub plots. Results showed thatincreasing the nitrogen rate from 0 to 225 kg/ha and increasment in soil water, causedincreasing seed yield, oil yield and protein yield. In water stress condition the seed oildecreased (7.17%) but the seed protein increased (8.31%). Increasing nitrogen usedcaused to decreasing seed oil (10.08%) and increasing seed protein (25.19%). Oilyield had strong and significant correlation with seed yield and oil percent. Also,protein yield had positive and significant correlation with seed yield. In contrast thetwo varieties, Zarfam had a higher nitrogen uptake and mobilization under normalirrigation and severe water stress conditions, and also in higher and lower nitrogenconditions.
