چکیده

A Cellular Automata model for soil erosion by water, SCAVATU, was developed. It involves a larger number of states in comparison to the previous models: alti-sidering some of the most significant processes of the phenomenon: water flow, infiltration, soil erosion by water flow, sediment transport and deposition. Simulations gave encouraging results, in agreement with the findings of other studies. ________________________________________________

Simulation of Future Land Use Map of the Catchment Area, with the Integration of Cellular Automata and Markov Chain Models Based on Selection of the Best Classification Algorithm: A Case Study of Fakhrabad Basin of Mehriz, Yazd

INTRODUCTION Since the land use change affects many natural processes including soil erosion and sediment yield, floods and soil degradation and the chemical and physical properties of soil, so, different aspects of land use changes in the past and future should be considered particularly in the planning and decision-making. One of the most important applications of remote sensing is land ...

A Soil Erosion Model Based on Cellular Automata

It is of great significance to dynamically simulate and forecast the development and evolutionary of soil erosion process. Traditionally, most of soil erosion models are essentially steady-state models. Thus, they have limitations at real-time simulation on the initiation and development of soil erosion process. Cellular Automata (CA), with a “from down to up” dynamic modeling framework, is cap...

Detection and prediction of land use/ land cover changes using Markov chain model and Cellular Automata (CA-Markov), (Case study: Darab plain)

unprincipled changes in land use are major challenges for many countries and different regions of the world, which in turn have devastating effects on natural resources, Therefore, the study of land-use changes has a fundamental and important role for environmental studies. The purpose of this study is to detect and predicting of land use/ land cover (LULC) changes in Darab plain through the Ma...

Comparison of two MPSIAC and MMF models in soil erosion mapping of Ardebil Agh Gouni watershed

Extended abstract 1- Introduction Soil erosion is the most important cause of land degradation and the cause of water loss, soil loss, sedimentation in water resources, and maximum flood intensification (Liu et al., 2019). Models are the most important tools for estimating and mapping of erosion at the watershed level. As the experimental models are dependent on used coefficients and region c...

Edge Detection Based On Nearest Neighbor Linear Cellular Automata Rules and Fuzzy Rule Based System

 Edge Detection is an important task for sharpening the boundary of images to detect the region of interest. This paper applies a linear cellular automata rules and a Mamdani Fuzzy inference model for edge detection in both monochromatic and the RGB images. In the uniform cellular automata a transition matrix has been developed for edge detection. The Results have been compared to the ...
