| Abstract | Hill Irrigation falls in a class of its own due to its mountain setting and scale. The
conveyance systems of Hill Irrigation have to be developed appropriate to its setting and scale.
The conveyance systems of Hill Irrigation are dealt in this study more on the practical fieldbased
perspective than on theoretical level.
The study outlines some of the measures required at the diversion point to control sediment
intrusion into the irrigation canals. The factors that should influence the choice of diversion
structures is presented. The sediment related problems of hill irrigation system is presented
against the background of the wider environmental problems of the mountain watersheds. The
study confirms the need for control of sediment at various levels; at the watershed to the
scheme level. Prevention and mitigation measures of sediment problems in the form of long
and short term solutions are proposed. An attempt is made to compute the water duty of the
study area by CROPWAT Programme with the input of more reliable climatic data. The high
conveyance losses found by the study on Hill Irrigation confirms the need to upgrade the
conveyance structures. The low conveyance efficiency is due to the poor state of the
conveyance systems and the poor management of the canals by the beneciaries. The study
reveals the need for research on alternative low-cost lining materials. Improvement in the
design of some component of the conveyance structures is included as found necessary from
the field study.
An assessment of the Water Users Association as an organization to carry out O&M of
irrigation infrastructure is included. The assessment is centred on the organization's capability
mainly in terms of resources and skills. The beneficiaries are constrained by lack of resources
and skills for satisfactory management of the irrigation schemes. |
