Reservoirs are principal water resources that supply irrigation water to paddy fields and play an important role in water resources management in South Korea. For optimal irrigation reservoir operation and management, it is necessary to determine the duration of irrigation water shortages. Management of reservoir operation and irrigation scheduling should take into consideration essential varia...

In constraint-based scheduling, storage systems are modelled by a class of resource called reservoir. Activities can either produce or consume a capacity in a reservoir. Most of the models presented in the literature assume that the production and the consumption is instantaneous but they are not good for some class of problems. This paper introduces the continuous reservoir model in which the ...

Reservoir characterization plays a crucial role in modern reservoir management. It helps to make sound reservoir decisions and improves the asset value of the oil and gas companies. It maximizes integration of multi-disciplinary data and knowledge and improves the reliability of the reservoir predictions. The ultimate product is a reservoir model with realistic tolerance for imprecision and unc...

Declining reservoir storage has raised the specter of the first water shortage on the Lower Colorado River since the completion of Glen Canyon and Hoover Dams. This focusing event spurred modeling efforts to frame alternatives for managing the reservoir system during prolonged droughts. This paper addresses the management challenges that arise when using modeling tools to manage water scarcity ...

pricing policies play an important role in water demand management and its optimal allocation. determining proper water price leads to optimal allocation of water especially in agricultural consumptions. applying new subsidy targeting law in iran which insists on pricing water based on its supply cost, will effects considerably on water resource management in agriculture sector. so, in this stu...

Executive Summary The objective of Reservoir Monitoring Consortium (RMC) is to develop new methods for dynamic reservoir monitoring. We will carry out a number of focused applied research projects in reservoir monitoring that are directly pertinent to the current and future needs of our industry sponsors. We will develop specific workflows for different types of reservoirs. This will include th...

OBJECTIVES Recent studies have suggested the occurrence patterns and related diet factor of esophagus cancer (EC) and gastric cancer (GC). Incidence of these cancers was mapped either in general and stratified by sex. The aim of this study was to model the geographical variation in incidence of these two related cancers jointly to explore the relative importance of an intended risk factor, diet...

BACKGROUND Esophageal squamous cell carcinoma (ESCC) is a major health problem in many developing countries including Iran. ESCC has a very poor prognosis, largely due to late diagnosis. As a first step in developing an early detection and treatment program, we conducted a population-based endoscopic screening for ESCC and its precursor lesion, esophageal squamous dysplasia (ESD) in asymptomati...

BACKGROUND Zoonotic Cutaneous Leishmaniasis (ZCL), an important public health problem in Iran, is sensitive to climate conditions. This study aimed to examine dynamic relations between the climate factors and incidence of ZCL in Golestan Province, northern Iran during 2010-2012. METHODS Data of monthly climatic factors, including temperature variables, relative humidity variables, evaporation...
