Numerical Analysis of an Upstream Tailings Dam Subjected to Pond Filling Rates

Floods from tailings dam failures.

This paper compiles the available information on historic tailings dam failures with the purpose to establish simple correlations between tailings ponds geometric parameters (e.g., dam height, tailings volume) and the hydraulic characteristics of floods resulting from released tailings. Following the collapse of a mining waste dam, only a part of tailings and polluted water stored at the dam is...

Poroelastic loading of an aquifer due to upstream dam releases.

Short-term changes in the hydraulic head of surface water bodies are known to influence the shallow response of hydraulically connected groundwaters. Associated with these fluctuations is the physical increase in stream water creating a mechanical load on the ground surface. This load is supported by the geologic materials (sediment or rock) and the pore fluid contained within the pores. Change...

Diversion of Water from a Tailings Dam

Instrumentation Readings versus Numerical Analysis of Taham Dam

Dam construction is one of the challenges among large-scale projects of a country. Among different types of dams, due to special features, earth dams are the most kind of dams that were constructed in Iran in the past three decades. Features such as efficiency and stability of earth dams have an important effect on their operation and prevent them to be damaged. Taham dam is clay core dam which...

an infinite planar array of rectangular microstrip patch antenna analysis

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
