Abstract

The use of artificial zeolite (AZ) derived from recycled material as a soil amendment has recently received much attention. The effectiveness of AZ in controlling soil loss, sediment concentration, and runoff water quality in artificial sodic soils is discussed in this study. Soils containing 3 different types of clay mineralogies (kaolinitic, smectic, and allophanic) were tested. Aggregate fractions with sizes >2000 µm and saturated hydraulic conductivity were considerably decreased due to aggregate dispersion after soil sodification, although the sodic KS soil was most stable. The addition of 10% AZ to sodic soil improved the mean weight diameter (MWD) and saturated hydraulic conductivity due to a decrease in exchangeable sodium percentage, resulting in a reduction in soil aggregate dispersion. This improvement of sodic soil with AZ had a beneficial effect on erodibility (soil loss and runoff water). This is attributed to the increment in soil infiltration as a result of the suppression of seal formation on the soil surface. The suppression of erodibility effectively controlled the salt concentration of runoff water. A beneficial effect of MWD and AZ contents on sediment concentration was observed, and a negative influence of electrical conductivity. These findings complement the role of AZ in controlling soil erosion.

Abstract

We investigated a method to measure sheet erosion by characterising the soil erosion of an upland field in a dryland environment. Digital photogrammetry was used to measure the erosion rates of soil surfaces packed to different densities under simulated rainfall or wind conditions. The photogrammetry system consisted of 2 digital cameras, a rainfall simulator, a wind tunnel, and a computer program for 3-dimensional algorithm analysis. First, we assessed the accuracy of our method by comparing conventionally measured data to photogrammetric data under conditions of either no rainfall or no wind application. Two statistical parameters were used to evaluate the soil surface evolution: the mean absolute error (MAE) and the mean relative error (MRE). Their values were 0.21 mm and 15.8%, respectively. We then assessed the precision of our system under simulated rainfall conditions using 3 different dry bulk densities for the packed saturated soil surface. At densities of 0.91, 0.98, and 1.09 g/[cm.sup.3], the MAE (MRE) values were 2.21 mm (392.5%), 1.07 mm (126.4%), and 0.59 mm (57.6%), respectively. It was possible to monitor and evaluate both the amount of eroded soil and the erosion mechanism in a specific area. Moreover, this system could be applied to measuring wind erosion with an MAE accuracy as high as 0.21 mm. The digital elevation models (DEMs) allowed for detailed analyses of soil surface evolution, and it was also possible to monitor sheet erosion with high spatial and temporal resolutions. Additional keywords: soil erosion, photogrammetry, precision, bulk density., Introduction Soil degradation resulting from accelerated water- and wind-induced erosion is a serious problem in drylands, and will remain so throughout this century. The detachment and transport of soil particles [...]

338. Tolling for Traffic Flow Networks: Positive Systems Modeling and Control

Author

Udagawa, T. and Inoue, M.

Abstract

This paper addresses modeling and control of traffic flow networks aiming at reduced congestion. We first develop a state-space model of expressing city-level traffic flow controlled by tolling, which is in a class of positive systems depending on some designable parameters. Based on the positivity of the model, we next present a design method of optimal tolling in terms of nonlinear programming. The nonlinear programming is transformed into a linear one, which is numerically tractable, by applying the change of variable technique. Finally, the effectiveness of the presented tolling design is shown through a numerical experiment.
