| Abstract | Hanoi lies in the Red River Basin which was formed as a
result of the tectonic reactivation at the end of Paleogene
subperiod. The basin was filled with Neogene and Quaternary
sediments. Sediments exposed in Hanoi range in age from
Pleistocene to Holocene epoch and consist of Thai Binh, Hai
Hung and Vinh phuc formations of different origins. The
landform features include alluvial terrace, back swamp, natural
levees and oxbow lakes. Hanoi is located on an active seismic
region belonging to the soft earthquake environment where
maximum magnitude could reach the value of about 6.5. The area
is under annual flood threat . The Red River dike system has an
ability to control flood up to an elevation of 13. 5 m above
MSL . Hoa Binh reservoir would cut off flood peak at Hanoi by
about 1.2 m. Typhoon caused heavy losses in the coastal area of
Vietnam. There are some foundation problems such as
differential and excessive settlements du e to unadequate
geotechnical investigation and foundation design. Construction
materials used in the city are allu:vial sand, silt and clay.
Present rate of solid waste production is 840tons/day or 0 . 68
kg/person/day . Sanitary landfill method is used for solid waste
disposal at Bode site. This site could spread diseases and
contaminate t h e environment during flood period. Surface water
is abundant and is used only for irrigation purpose . Middle Lower Pleistocene aquifer has an estimated extraction discharge
of 2.13 million m3 /day. Quality of ground water of the aquifer
is good except concentration of iron and manganese cations is
rather high. |
