Abstract:This study aimed to evaluate the accuracy of object-oriented classification with and without the use of fuzzy algorithms, compared with pixel based algorithm in land use/ land cover classification. In order to compare different methods, AVNIR2 sensor images obtained from ALOS satellite were used to classify land use in Maragheh County. The results indicated that object-oriented classification approach produced more accurate results than pixel-based, So that the fuzzy knowledge based ...

In order to determine the height of the filter in heterogeneous earth dam, three embankment models were provided in a flume laboratory, with the length of 4.2 m at the base of dam, the width of 60 cm and the height of 1 m and body slope 1H: 2V. For embankment of model, two types of fine and coarse grained soils were used. The texture of the soil was made using hydrometer method. In the first model, the fine-grained and coarse-grained soils were used in downstream and upstream of the dam crest...

The unsteady flow can be analyzed by Saint-Venant equations. These equations can be solved by characteristics and finite difference methods. The Saint-Venant equations are changed into four complete differential equations in characteristics method and these equation are solved by drawing two characteristics lines. The Saint-Venant equations are changed into a set non-linear equations and are solved using Preissman scheme in finite difference method. This set equation are changed into linear e...

For determining of Muskingum model coefficients, requires to an output hydrograph. Such hydrograph is not available in most rivers. In this research, the Muskingum's new coefficients are determined by the method that which is not require to output hydrograph and its accuracy is high. This coefficient is determined based on kinematic wave model with suitable scheme. The comparison between results of Muskingum model with new coefficients and dynamic wave model, showed that the new coefficie...

The type of water in a story or novel is just as important as the fact that water is used as a symbol. Rivers often represent the flow of life or fertility. Rivers are typically used as symbols by authors because rivers flow; they are constantly moving and they follow a distinct path. Oceans, on the other hand, because of their scope in relation to the earth, often represent obstacles or abysses from which things emerge or that characters must journey across to reach a destination. Oceans are...

Excessive use of chemical fertilizers, especially nitrogen fertilizers to increase crop and improper purification, and delivery of municipal and industrial wastewater are proposed as factors that increase the amount of nitrate in groundwater in this area. Thus, investigation of nitrate contamination as one of the most important environmental problems in groundwater is necessary. In the present study, modeling and estimation of nitrate pollution in groundwater of marginal area of Zayandeh-rood...
