  • Objective and Subjective Factors Influence on Demand of Drainage by Pumping in Red River Delta

    • Authors: Dang Ngoc, Hanh (2010)

  • The demand for newly constructing of drainage pumping station in Red river delta has increased recently. Total drainage volume for the whole region in 2006 was 2406.8m3/s, and it was predicted to increase to 5181.3m3/s in 2020 [1]. The average drainage coefficient for the year from 2010 to 2020 will be 7.0 l/s per hectar, three and a haft time higher than the average drainage coefficient for the period from 1954 to 1973; 1.8 times higher than 1973 to 1976 and 1.3 times higher than 1976 to 2000. This article aims to provide the primary analysis of objective (drainage requirement) and subjective factors (socio-economic condition, psychology, information, etc) influencing on the demand o...

  • On some significant unconformities in the Paleozoic and Mesozoic stratigraphy of North Viet Nam

    • Authors: Tong Dzuy, Thanh (2007)

  • A lot of unconformities and stratigraphic gaps have been discovered in the Paleozoic and Mesozoic stratigraphy of Bac Bo region (North Viet Nam), but their role in the regional geology was not accessed yet in detail. This paper is the first attempt to describe the most significant unconformities and stratigraphic gaps and discussing their role in regional geology. The most important is the angular unconformity of Norian-Rhaetian formations upon various formations of different formations; it marked the change tectonic regime of the region resulting from the indosian orogeny in Viet Nam and in Southeast Asia in common. The gap of Lower Devonian red beds formations (Si Ka Formation, Song...

  • On the detection of gross errors in digital terrain model source data

    • Authors: Tran Quoc, Binh (2007)

  • Nowadays, digital terrain models (DTM) are an important source of spatial data for various applications in many scientific disciplines. Therefore, special attention is given to their main characteristic - accuracy. At it is well known, the source data for DTM creation contributes a large amount of errors, including gross errors, to the final product. At present, the most effective method for detecting gross errors in DTM source data is to make a statistical analysis of surface height variation in the area around an interested location. In this paper, the method has been tested in two DTM projects with various parameters such as interpolation technique, size of neighboring area, thresh...

  • Paleomagnetism of cretaceous continental redbed formations from Indochina and South China, their Cenozoic tectonic implications: a review

    • Authors: Cung Thuong, Chi (2007)

  • Available paleomagnetic data of Cretaceous redbed formations from Indochina and South China blocks are compiled and their tectonic significance is reviewed in a common reference frame of the Eurasian coeval paleopoles. The important factors that play a vital role in determining the tectonic significance of a paleomagnetic result have been taken into consideration and discussed. Review of the Cretaceous paleomagnetic data from the South China block further confirms the conclusion of the previous researchers that the present geographic position of the South China block has been relatively stable with respect to Eurasia since Cretaceous time and shows that the paleomagnetically detected ...

  • Pattern and determinant agents of the debris and mud flash flood in Lay Nua Commune area, the Former Muong Lay District, Dien Bien Province

    • Authors: Dao Dinh, Bac (2007)

  • This paper discusses debris and mud flash flood, which is a widespread phenomenon with different levels of damaging effects and repetition in the mountainous areas of Vietnam. There are some sites where the flash flood with severe debris components has recurred many times and it has always caused heavy loss of human and materials, such as Lay Nua Commune, the Former Muong Lay District, Dien Bien Province. During the 1990s, this kind of severe hazard is recorded to occur every two years in the town of Former Muong Lay District. This leads to the government’s decision to relocate the town to another place. Some characteristics of physiographical conditions such as climate, relief, litho...
