This paper describes a wireless sensor network that monitored water extraction rate, salinity and water table level. The network collected real-time water quality measurements in order to investigate the impacts of current irrigation practice on the environment, in particular underground water salination. Particular challenges included a large coverage area, a sparse network with mean link dist...

Koot - Hamoodi are two units from seventh units out of 1&2 irrigation and drainage network in Dasht-Azadeghan project where was past about 7 years from their operation. Results of the studies were showed before construction of network; ground water table in considered of this area was high and more than 90% of these lands were high and too high in saline and alkaline. After construction and ope...

Both the economics and the engineering of irrigation design are typically based on the assumption of a single source. The more general economic problem is to determine which sources should be developed and how water should be allocated and delivered to various receptor-farmers. This is a problem in network economics. We begin our exploration with the problem of allocating irrigation water from ...
