In the design of earth dams, it must be considered that water leakage through dam generates upward and pore pressure, in addition to forces cause internal erosion, which has a direct influence on structural stability this system. Also, rising dropping level effect dam's face slope. One way solve these issues is installation core or horizontal drainage The present study relied GEO-Studio compute...

Methods: During the first 10 weeks after an outbreak of acute porcine reproductive and respiratory syndrome (PRRS) in a herd but prior to implementing McREBEL management, crossfostering was performed only within 24 hours of birth; however, because the manager was sizing and sexing all litters at birth, > 85% of piglets were being raised by a foster dam. Under the McREBEL protocol, crossfosterin...

we report engineering experiences from the critical task of relief well installation under high artesian flow conditions at the downstream toe of the karkheh earth dam, iran. due to the establishment of excessive uplift pressure at the downstream toe of the karkheh dam, installation of a series of new relief wells was considered to permanently relieve part of these pressures. the mentioned upli...

This paper introduces an accurate, fast, and applicable method for optimization of slip surfaces in earth slopes. Using Genetic Algorithm (GA), which is one of the modern and non-classic optimization methods, in conjunction with the&#10well -known Bishop applied method, the optimum slip surface in an earth slope is investigated and its corresponding lowest safety factor is determined. Investiga...
