High-resolution seismic reflection has been used successfully to characterize material and investigate a variety of problems associated with earthen dams and abutments. Limitations and challenges of seismic reflection when interrogating these structures and lithologies are nontrivial and require very critical thinking. Seismic reflection has proved an effective tool for mapping confining units ...

In this paper an example is elaborated of the design of a river dike, incorporating reliability-based models. The design is demonstrated with the help of this example, which is based on [1]. 1. PROBLEM DESCRIPTION A river dike has to be designed to protect a particular region of land. The goal is to minimize the construction cost and the expected loss, due to inundation. The total cost can be e...

Abstract Variable single and/or swarms of post-granitic dikes are widespread at Gabal Serbal, Southwestern Sinai, Egypt. The present article aims to identify and discriminate these multiphase through detailed geological, petrographical, geochemical examinations. These classified into two subphases: (1) acidic (porphyritic dacite, microgranite, granophyre, alkaline granophyre dikes); (2) basic (...

Al Huweizah Marsh is considered as the largest marsh at southern part of Iraq. About one third located within Iranian territory. Iran began to construct earth dikes along Iraqi-Iranian international borders separate marsh. The electrical conductivity, EC, value was adopted be indicator for water salinity A steady two-dimensional quality routing model implemented by using RMA2 and RMA4 softwares...

Field observations of active and fossil natural geothermal fields indicate that fluids are primarily transported along dikes fault zones. Fluid transport (commonly through fractures at their margins) is controlled by the cubic law where volumetric flow rate depends on aperture fracture in 3rd power. Dikes (and inclined sheets) also act as heat sources for fields. In high-temperature volcanoes I...

There is a growing concern about the safety of dams and dikes in modern society [...]
