Appropriate utilization of agricultural land and natural resources, decreased erosion and increased production occurs in watersheds. On the other hand, land use pattern due to increasing human activities on the ground to meet different needs, is changing. Optimization of land use is one of the management methods to achieve stability and reduce soil erosion. In this study, by using linear progra...

sistan plain is affected by desertification and this phenomenon has serious impacts on roads and socio- economic activities of local people of this region. the main purpose of this study is estimating the current and potential desertification intensity of niatak region of sistan based on micd method. that, through it the working units of this region were prepared as the base map for evaluating ...

In this paper, a numerical solution of an inverse non-dimensional heat conduction problem by spline method will be considered. The given heat conduction equation, the boundary condition, and the initial condition are presented in a dimensionless form. A set of temperature measurements at a single sensor location inside the heat conduction body is required. The result show that the proposed meth...
