Modern Land Drainage 2nd edition is a fully revised and updated
edition of the 2004 edition. Modern Land Drainage describes
traditional drainage formulas (Hooghoudt, Kirkham, Donnan, Ernst,
Glover-Dumm) for rainfed agriculture in the humid temperature zone.
Significant parts are devoted to drainage for salinity control of
irrigated land in (semi-) arid zones, and to drainage of rice land
in the humid tropics. Institutional, management and maintenance
aspects are extensively covered, as well as the mitigation of
adverse impacts of drainage interventions on the environment. The
latest computer applications for drainage design in the context of
integrated water management are described (DRAINMOD, HEC, SWAP,
etc.). Field surveys are executed by governments, with the aid of
consultants, but rarely are the end stakeholders (i.e., farmers and
general public) involved from inception to planning to execution of
a drainage system. Yet, during the Operation, Management and
Maintenance (OMM) phase of a water management system, they are
expected to takeover, run, bear and be responsible for the costs of
OMM. The book describes successful methodologies and processes to
be followed for engagement of stakeholders at all levels, from
government to farm, from minister to farmer, and, from beginning to
end. The book covers all aspects needed for sustainable drainage.
The latest survey methodologies with satellites and drones are
suggested to assess cause and effect. Waterlogging and salinity are
the effect of something caused most likely upstream of the drainage
problem location. Hence treating the cause may be more
cost-effective. Triple Bottom Line (social, environmental and
financial considerations) and the water-food-energy nexus are an
integral part of the drainage design process. Controlled drainage,
i.e. the balance of removal and conservation of drainage water and
minimising solute transport as low as reasonably achievable (ALARA
principle) is extensively described. This work is intended for use
both as a university level textbook and as a professional handbook;
it is of particular value to professionals engaged in drainage
development in the context of integrated water resources and river
basin management, civil and agricultural engineers, government
officials, university students and libraries.
