sugarcane, which has high water requirements, is grown in khuzestan province (iran). climate and optimizing the use of water is very important to sustainable cultivation of sugarcane. studies of water requirements for sugar cane in khuzestan show that in parts of sugarcane agro-industry, the water applied is more than the actual water requirement of the plant. the present study was conducted to...

[1] New closed-form expressions are introduced to capture the dependence of specific yield on time and depth to water table. The expressions allow the user to convert observations of water table fluctuations to volumes of water released from storage in a shallow water table aquifer. Whereas a linear relationship between water table fluctuations and released volumes holds for a deep water table ...

The effect of controlled drainage (CD) on ammonia volatilization (AV) losses from paddy fields under controlled irrigation (CI) was investigated by managing water table control levels using a lysimeter. Three drainage treatments were implemented, namely, controlled water table depth 1 (CWT1), controlled water table depth 2 (CWT2), and controlled water table depth 3 (CWT3). As the water table co...

Information about hydrological systems and water table fluctuations is important for water management and is needed to assess choices for long-term water management policy. Preferably, uncertainty about the future water table depths is quantified to enable risk assessment. The aim of this study is to map water table depths and quantify the associated uncertainty, in order to indicate extreme sc...

the management of water table is introduced as one of the major parts of the solutions in water resources management. this method could play a significant role in protecting water resources, increasing irrigation efficiency, preserving nutrients in soil, and protecting the quality of surface downstream, and as well, of groundwater. towards this end, a laboratory study has been done on the effec...

Pip is an internet protocol that scales efficiently encodes policy. It facilitates many advanced features, such as mobility and multiple defaults routing, and has a well-bounded routing table lookup, and is therefore fast. Pip is proposed as an alternative to the two “medium term” proposals that emerged from the Road (Routing and Addressing) group to deal with the dual IP problems of scaling an...
