| Abstract | Kathmandu area is mainly composed of thick lacustrine sediments about
400-650 m with some arenaceous limestone inliers and surficial alluvial
sediments. The mineral compositions are mainly sand grains of quartz and
feldspar, and black carbonaceous clay, with a lot of mica flakes, mixed
in various proportions . The landform features are characterized by four
valley plain terraces and flood plains. The hydrogeological regime is
highly influenced by the monsoon behaviour. The artesian and subartsian
ground water basin contains upto seven layers of aquifers with potable
water quality in the north and marshy water in the south. The area is very
prone to seismic hazard and the 1934 Nepal - Bihar Earthquake was the
biggest calamity in the area. The common type of foundation in residential
buildings is shallow strip footings with width varying from 0.45 m to 1
m and depthvarying from 1 m to 2 m. The range of ultimate bearing capacity
of soil was found to vary from 34 to 81 ton/sq. m. for sand, from 26 to
29 ton/sq. m for 11Kalimati" clay and from 21 to ยท24 ton/sq. m. for soil
containing sand and Kalimati clay . Various type of construction materials
are locally available. The necessary water is supplied from the reservoirs
located at the fririg.es by gravity flow system. Though solid waste materials are consumed by the Compost Plant, the city cannot be maintained
well . Likewise, land use and planning is becoming more and more important
since more than 50% of area has been already been covered by built-up
area . |
