Описание: Over 100 irrigation projects and systems can be found on Indian reservations primarily across the western United States. The scarcity of water in much of the western United States makes irrigation critical to agricultural activities. The Department of the Interiors Bureau of Indian Affairs (BIA) manages 16 irrigation projects on Indian reservations in the western United States. This book focuses on BIAs estimated deferred maintenance cost for its irrigation projects; shortcomings that the Government Accountability Office (GAO) identified in BIAs management of its irrigation projects; and issues GAO identified that needed to be addressed to determine the long-term direction of BIAs irrigation program.

Описание: Describes the application of cloud seeding technologies to facilitate the conversion of atmospheric water vapour into precipitation. Standard ANSI/ASCE/EWRI 42-17 provides an introduction to the history and technology of cloud seeding and describes the scientific basis for examining the efficiency of both natural precipitation and human-induced weather modifications.
Quantitative research with respect to the combination of engineering and socialcultural- religious aspects based on the Tri Hita Karana philosophy in Subak irrigation schemes is original in the field of land and water development. A scenario analysis needs a good and careful system approach. Based on a Generic Algorithm the RIBASIM model was applied using the dependable 80% of discharge and shifting the start of land preparation. The results provide evidence that the cropping pattern of the fifth scenario results in an overall optimal agriculture production of the Subak schemes.
The recoverable flow considered in the river basin scheme model plays an important role in the optimisation. Nevertheless, if a normal hydro-climate occurs, the other scenarios, especially the first scenario, can be applied as well. When the indigenous knowledge of farmers is compromised with present day knowledge of agricultural and technological developments, capability of these farmers increases, thus reflects the applicability of the Tri Hita Karana philosophy on harmony among people and harmony among people and nature.
