the effective management of available water for irrigation in arid region like iran has become increasingly important due to limited water supply. the need for irrigation water allocation in water limiting condition caused to use gis in order to manage information optimally and to have easy access. in the present study, the objective was to develop a planning support system to be adaptable to t...

8 The modernization of irrigation districts in Spain is based on the construction of 9 collective pressurized networks equipped with remote control systems. In this paper, a 10 simulation approach is used to explore the benefits of introducing a collective solid-set 11 irrigation control software. The controller works in combination with a district 12 management database, real time evapotranspi...

Population growth and increasing droughts are creating unprecedented strain on the continued availability of water resources. Since irrigation is a major consumer of fresh water, wastage of resources in this sector could have strong consequences. To address this issue, irrigation water management and prediction techniques need to be employed effectively and should be able to account for the var...

India is an agricultural country and agriculture is backbone of Indian economy. Agriculture provides the principal means of livelihood for the major Indian population. The optimum use of agriculture resources can lead to a good crop yield. Water resource is major constrain in agriculture so efficient distribution of available water is certainly beneficial to get good crop yield and hence profit...

Irrigation by benthic macrofauna has a major influence on the biogeochemistry and microbial community structure of sediments. Existing quantitative models of bioirrigation rely primarily on chemical, rather than ecological, information and the depth-dependence of bioirrigation intensity is either imposed or constrained through a data fitting procedure. In this study, stochastic simulations of 3...

The designating factors in the design of branched irrigation networks are the cost of pipes and the cost of pumping. They both depend directly on the hydraulic head of the pump station. It is mandatory for this reason to calculate the optimal head of the pump station as well as the corresponded optimal pipe diameters, in order to derive the minimal total cost of the irrigation network. The math...
