The use of forest roads as foundations for dam construction by beavers is a recurrent problem in the management of forest road networks. In order to limit the damage to forest roads, our goal was to calculate the probability of beaver dam installation on culverts, according to surrounding habitat parameters, which could allow for improvement in the spatial design of new roads that minimise conf...

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...

The focus of this study was to investigate the effect loess soil treated with lime on lateral-seepage response. Three groups box experiments were carried out under different types loess-lime structures. Automated testing systems designed perform and collect data. Additionally, numerical analysis impact embankment settlement performed. Finally, moisture content monitored quantify results corresp...

Finite element method (FEM) based analysis using the SEEP/W and SLOPE/W sub-programme options of a GEOSTUDIO software was used to analyze Saura-Keffi earth dam in Nasarawa State, Nigeria with view seepage its stability. The created geometry assigned material properties boundary conditions at reservoir water levels of: minimum (3 m), normal (6 m) maximum (7 m). conducted under cases that without...

Dispersive clay soils are highly erodible, even under standing water conditions. easily eroded both on the surface and in landfills, despite their high plasticity index ability to be passed by flows at low velocities. soil will cause a variety of problems dams structures, including potential for seepage patterns embankment material, which can trigger piping, compromising stability structure. oc...

In order to monitor dam safety condition better, a Dynamic Bayesian Networks (DBN) model is developed to overcome the shortcomings of the ordinary monitoring methods in this paper. Ordinary methods include comprehensive assessment methods and numerical simulation methods. Comprehensive assessment methods have shortcomings such as weight determination, scale difference, variables correlation, et...

upstream blankets, drains and cutoff walls are considered as effective measures to reduce seepage, uplift pressure and exit gradient under the foundation of hydraulic structures. to investigate the effectiveness of these measures, individually or in accordance with others, a large number of experiments were carried out on a laboratory model. to extend the investigation for unlimited arrangement...
