coastal areas usually involves in several kinds of water use, such as agricultural, industrial, and drinking, which are needed to be considered as important in water management systems. there is a need to study the sustainable water resources management in different terms. a combined methodology, which considers the human activities, as well as environmental problems according to some criteria,...

Today an integrated and complete system for the monitoring and management of water resources for a whole river basin does not exist. This paper presents the characteristics and showcases the design of such a system. The core of the system is based on water quality monitoring and risk management. This paper also highlights the need for the economic evaluation of water resources services, and pre...

in this research the simulation of an air independent proton exchange membrane fuel cell (pemfc) propulsion system was taken into consideration. the system consists of several parts including pem fuel cell stack, metal hydride and liquid oxygen (lox) tanks, and also pre-heaters of oxygen and hydrogen gases along with other heat exchangers, to ensure proper operation of system. the heat recovery...
