Abstract: The design of retaining walls requires the complete knowledge of the earth pressure distribution behind the wall. Due to the complex soil-structure effect, the estimation of earth pressure is not an easy task; even in the static case. The problem becomes even more complex for the dynamic (i.e., seismic) analysis and design of retaining walls. Several earth pressure models have been de...

Estimation of sediment transport load due to erosion in river basins is one of the issues which is indispensable for many projects related to water resources, soil and damps construction. With regards to the phenomenon of erosion and transmission Sedimentation in rivers has always led to deformation in the seaboard and sedimentation, so the management and planning in bank of rivers is important...

The motions of all known Earth approaching asteroids and comets with reasonably secure orbits have been numerically integrated forward in time to A.D. 2200. Special care was taken to use the best available initial conditions including orbits based upon radar data. Each object was integrated forward with Earth and moon perturbations treated separately, with general relativistic equations of moti...
