| Abstract | This dissertation deals with diverse, yet interrelated empirical and
conceptual problems encountered in integrated water resources planning
and management . Particular attention is paid to the proposition of an
integrated water resources development and management policy in a typical
sub-Himalayan river basin in Nepal - the Tinao River Basin.
Both the surface and ground water resources are assessed and analyzed
for the irrigation development of the basin; alternative schemes are
identified and evaluated. The combined use of surface and ground water
has great advantage when it is necessary to utilize water resources which
are limited and variable in time and space, to their optimum.
Incorporation of artificial ground water recharge is recognized as a
promising solution to various water management related problems both from
economic and environmental considerations. Another important key to the
evolution of the integrated water management policy is the basinwide
planning and management approach.
Working mathematical tools for analyzing and optimizing integrated
use of surface and ground water resources for irrigation are developed
and applied to the illustrative basin . A solution strategy based on
physical decomposition of a large system and solution by a multilevel
iterative technique is also developed. This scheme allows us to determine
detailed cropping patterns in various parts of the basin, and
simultaneously derive system design capacities and monthly water
allocation policies. The results of the model application to the study
basin indicate that both the surface and ground water irrigation
facilities should be developed for obtaining optimum agricultural
benefit. The management policy is to use ground water when the surface
supplies are too low; and when the surface supplies are in excess,
surpluses would be used to replenish the ground water shortages by
artificial recharge. The separate yields of surface water and ground water
developments would be replaced by the larger and more economical joint
yields of the combined resources. |
