Slope stability is one of the most important issues in open pit mining design. The main purpose of any open pit mine design is to propose an optimal excavation configuration, considering safety, ore recovery and financial return. An accurate pit slope design which accounts for the mine geology, structural geology, rock mass properties, and hydrogeology models of the mine area, drastically enhan...

This research was aimed to simulate and prioritize the effective factors on water erosion using USLE-M in the system dynamic model. In this integrated model, by using the system dynamic simulation software (Vensim), all variables and factors involved in erosion and soil loss were considered according to the USLE-M model. After model implementation, the estimated values and observations were com...

Genetic programming has been widely used in the engineering field. Compared with the conventional genetic programming and artificial neural network, geometric semantic genetic programming (GSGP) is superior in astringency and computing efficiency. In this paper, GSGP is adopted for the classification and regression analysis of a sample dataset. Furthermore, a model for slope stability analysis ...

Manual surveying methods have long been used in the field of highway engineering to determine the cross-slope, and longitudinal grade of an existing roadway. However, these methods are slow, tedious and labor intensive. Moreover, manual survey methods almost always require partial or full lane closure resulting in traffic delays, increase in costs, and inconvenience to the travelling public. In...

abstract: the aim of this study is analysis of drainage basins neotectonic in the north slope of bozqoosh mountains by geomorphological methods. to attain this aim, it used of field observation, areal photographs and five geomorphic indexes in 20 basins of the north slope of bozqoosh mountains. indexes were calculated by topography maps (1: 50000), geological maps (1: 100000) and areal photogr...

The present study was conducted in Mollaahmad watershed of Ardabil city in 1390 to evaluate the canonical correlation between tillage erosion [slope gradient and position], and grain yield and barley yield components (Sahand cultivar) in order to determine the covariability between the two sets of variables to (1) detect simultaneously occurring patterns in the interdependencies sets of canonic...

Due to recent developments in concert hall design, there is an increasing interest in the analysis of sound energy decays consisting of multiple exponential decay rates. It has been considered challenging to estimate parameters associated with double-rate (slope) decay characteristics, and even more challenging when the coupled-volume systems contain more than two decay processes. To meet the n...

When using a 3D deterministic model to evaluate the landslide susceptibility of regional area, processing large amounts of spatial data and identifying the objective for applying the deterministic model would be arduous works. In this research, an enhanced hydrology tool is developed to automatically identify the objectives of research, which are called slope units, from terrain raster data. A ...
