Here is the second set of exercises. These are intended to cover subject groups 5-8 of the SOC/DAM syllabus (ABD, SFT, RD, E). These questions are styled as Tripos questions, with 20 marks each, but they largely involve repeating what was lectured. Tripos exam questions this year will be certainly be no harder than anything in these exercises. (In future years, questions that require a greater ...
A computational methodology dedicated to embankment dam performance assessment has been designed and implemented. The model’s inputs are the whole set of available information and data: visual observations, monitoring measurements, calculated data and documents related to design and construction processes. Firstly, a formal grid is proposed to structure the inputs. It is composed of six fields:...
A 3-D finite element (FE) numerical model was used to analyze structurally a proposed subsurface concrete dam to serve as a strategic water supply storage for the Holy city of Makkah, Saudi Arabia. The work was done mainly to show the behavior of the subsurface dam under the subjecting loads. The plastic concrete was chosen for the construction of the cut-off wall required for the reservoir. Th...
Here is the first set of exercises. These are intended to cover subject groups 1-4 of the SOC/DAM syllabus (R, SC, SD, ESL). These questions are styled as Tripos questions, with 20 marks each, and they largely involve repeating what was lectured. (In future years, questions that require a greater amount of creative thinking might be set). Full model answers and answer notes are available (for s...
Abstract. A seasonal investigation of the occurrence of metacercariae in cyprinoid fish was conducted at the Kwae Noi Bamroongdan Dam, Phitsanulok Province, northern Thailand during December 2008-August 2009. A total 361 cyprinoid fish from 10 species were examined by artificial digestion method evaluating for metacercariae. The metacercariae determined were Haplorchis taichui, Haplorchis pumil...
Ground-based synthetic aperture radar (GBSAR) is a powerful tool used in monitoring structures, such as bridges and dams. However, despite the extremely short range of GBSAR interferometry, the atmosphere effects cannot be neglected. The permanent scatterer technique is an effective operational tool that utilizes a long series of SAR data and detects information with high accuracy. An algorithm...
The damming of a river causes dangerous consequences on structure of the environment downstream of the dam, modifying the sediment composition, which impose major adjustments in longitudinal distribution of benthic community. The construction of Engenheiro Sérgio Motta Dam in the Upper Paraná River has caused impacts on the aquatic communities, which are not yet fully known. This work aimed to ...
China's historiographical traditions tell of the successful control of a Great Flood leading to the establishment of the Xia dynasty and the beginning of civilization. However, the historicity of the flood and Xia remain controversial. Here, we reconstruct an earthquake-induced landslide dam outburst flood on the Yellow River about 1920 BCE that ranks as one of the largest freshwater floods of ...
