| Abstract/Contents: | "Runoff and associated erosion have been recorded using a portable rainfall simulator (rain intensity of 55mm/h, 2.2 in/h) and four types of organic tackifiers, at concentrations of 5 and 10 gr/l (0.662 and 1.324 oz/gal). The tackifiers used differ in both origin and texture (A and B were derived from vegetable seed endosperm while C and D came from seed husks). A control was also used. Also had been carried out, the percentage of moisture retained was calculated for each treatment at a pressure of 0.33 atm (field capacity) and 15 atm (at the point of wilting up). The values obtained for erosion rates, indicate that product C, at a concentration of 10 gr/l (1.324 oz/gal) offers greatest capacity of sediment retention [erosion rate (T.E=4.62 gr/mĀ²/h, 0.0147 oz/sq ft/h] compared to the control (T.E=127.71 gr/mĀ²/h, 0.4086 oz/sq ft/h). With reference to runoff, the coefficients demonstrate that there are no differences between the control and products A and B at a concentration of 5 gr/l (0.662 oz/gal), the intermediate values for the tackifiers A, B and D at 10 gr/l (1.324 oz/gal) and D at 5 gr/l (0.662 oz/gal) with the lowest coefficients corresponding to product C at concentrations of 5 and 10 gr/l (0.662 and 1.324 oz/gal). With respect to retained moisture at pressures of 0.3 atm [moisture of control=19.87%; moisture of product C at a dosage of 10 gr/l (1.324 oz/gal)=8.94%], significant differences were not found, which indicates that in the test soil these tackifiers did not improve or increase moisture levels." |
