dc.description.abstract |
For a proper diagnosis of drainage
problems one must have the appropriate soils
information. The required soil data have to be of
morphological, physical and chemical nature to relate
to the hydrological problems. Soil mechanical
interpretations and civil engineering aspects must also
be kept. A survey of the water table is one of the most
important parts of any drainage investigation. For a
well-balanced drainage plan, the soil data will be
include active gley phenomena, which give a reasonable
idea of the fluctuations in groundwater levels. Reduced
soil materials, Gr, that are permanently saturated have
a characteristic gleyic colour and the horizon Gr must
be present in the first 50 cm of the soil profile. Gleysols
can be used for arable cropping, provided the
groundwater table is lowered or groundwater seepage
from the uplands is intercepted. A common soil survey
offers soil data only for a depth of 1 to 1.5 meter. For
hydrological calculations it is necessary to know the
composition of the subsoil, even to depths of 50 to 100m.
For tile drainage, it is necessary to know the
characteristics, to a depth of at least 4 to 5 meters. For a
drainage plan, the following soil data will be required:
active gley phenomena, permeability, available water,
salinisation and sodication problems, rippening;
maturation. The drainage specialist will find the
sensitivity analysis a useful tool in guiding the required
soil and geohydrogeological investigations, which differ
from project to project, and in working out alternative
solutions regarding the use of pipe drains or ditches,
drain depth, etc. |
