ABSTRACT: Water quality of dam storage is highly affected by upstream environment and basin. Regarding other conducted studies, there exist various reasons such as some studies and general monitoring of dams which cause some main problems including salinity, chemical and microbial pollution eutrophication, and sedimentation. Chame-Gardalan Storage Dam in Ilam Province is one of the storages whi...

The modification of Amazonian rivers by the construction of megaprojects of hydroelectric dams has widely increased over the last decade. Robust monitoring programs have been rarely conducted prior to the establishment of dams to measure to what extent the fauna, and its associated habitats may be affected by upcoming impacts. Using bats as models, we performed analyses throughout the area unde...

Multi-layer neural networks have been used in this paper for modeling nonlinear behaviour of concrete gravity dams under earthquake excitation. Koyna dam which has been studied extensively by other authors in the past has been studied as test example in this paper too, where the nonlinear response of its crest has been modelled by the proposed algorithm. The main steps of the algorithm are as f...

Many countries are implementing new dam safety regulations that often include more restrictive standards. This, together with the increasing average age of dams, results in a greater need for dam control and maintenance works. The advances in information and communications technologies improved the performance of dam monitoring systems, so a large amount of information on the dam behaviour can ...

Therefore, the performance could be achieved in a more realistic man...

We have developed a microfluidic device for on-chip monitoring of cellular reactions. The device consists of two primary analytical functions: control of cell transport and immobilization, and dilution of an analyte solution to generate a concentration gradient. In this device, a dam structure in parallel to the fluid flow was constructed for docking and alignment of biological cells, which all...

Earthen embankments including levees, tailings dams, and earthen dams present many challenging problems for Civil Engineers, particularly in verification of their structural integrity and capacity, operation and maintenance (O&M), inspection, and safety. The sheer size and scale, age, and uncertainty of materials in these sometimes mammoth structures, all combine to present a difficult array of...

When creating computational models of engineering structures, it can be very helpful to have insights into the behavior and composition of the physical system. Such insights can be gleaned using data mining techniques, where often unexpected relationships between physical quantities can be made evident. In the context of an agent-based research project to monitor dams, a number of sensors suppl...

Abstract Displacement monitoring method of reservoir dam is a key research topic at present. In order to better display the overall efficiency horizontal displacement and vertical monitoring, numerical simulation analysis ecological small based on maximum entropy algorithm proposed. The virtual value calculated by algorithm, probability distribution function random variables obtained. comprehen...
