The improvement of irrigation systems in the Nile Delta is one of the most important attempts in Egypt to implement more effective irrigation technology by improving the existing irrigation networks. Demand delivery system in the existing irrigation network is using of mechanical gates structures to automatically divert water from one portion of an agricultural field to another in the desired a...

A field crop irrigation management decision-making system (CropIrri) was developed based on the soil water balance model, crop phenology model, root growth model, crop water production function, and irrigation management model. The irrigation plan is made through predicating of soil water content in root zone and daily crop water requirement using historical and forecasting weather data, measur...

In the proposed Irrigation system IoT is implemented, in this system all the information that are received from the sensors and the various parameters are given to the arduinouno microcontroller as an analog input. A preset value of soil moisture sensor is fixed in microcontroller and also for fencing. When it goes beyond the particular threshold value water is automatically irrigated to the cr...

An irrigation scheduling model (ISM) consisting of a database management system (DBMS), model base and graphical user interface (GUI) was developed for performing irrigation scheduling under various management options for both single and multiple ®elds. The ISM is based on a daily water balance approach and uses climatological, crop and soil data as input. Depending on the availability of clima...

BACKGROUND Burr hole craniostomy is a widely used method for the evacuation of CSDH. However it is not clear whether the irrigation during operation improves the prognosis or gives rise to additional complications instead. This retrospective cohort study was conducted to determine this issue. METHODS Patients attending two medical centers in China who underwent burr hole drainage with irrigat...

Improving water efficiency in irrigated agriculture is a priority for better environmental and economic performance. It can be achieved by reducing the amount of water used and optimizing the timing of application. Among numerous methods, hybrid biophysical/decisional simulation models are effective tools for evaluating and comparing irrigation strategies under different weather conditions. How...

A greenhouse study was conducted in sand cultures to compare the effects of saline irrigation waters applied by two different methods, flooding and above-canopy sprinkling, on selenium (Se) accumulation by the forage brassicas, kale (Brassica oleracea L., cv. ‘‘Premier’’) and turnip (B. rapa L., cv. ‘‘Forage Star’’). The composition of the irrigation water was designed to simulate saline (7 dS ...

Sprinkler irrigation is a common farming practice in those states where the semi-arid climate and lack of sufficient rainfall during critical growing periods necessitate the use of supplemental water. The source of most irrigation water is groundwater which can be contaminated with volatile organic compounds (VOCs). Since the groundwater may be the primary or only source of drinking water for a...

OBJECTIVE To evaluate the efficacy of positive-pressure nasal irrigation devices in children with acute sinusitis, in addition to bacterial colonization of the irrigation device. METHOD We performed a randomized, prospective, controlled study of 80 children with acute sinusitis, aged between 3 and 15 years. Participants were randomly separated into two groups, where one group was treated usin...

Available water resources for agricultural irrigation have decreased worldwide in recent decades, prompting advances in water saving methods. In this study, soil water regime and water balance in a transplanted rice field with reduced irrigation (multiple shallow depth irrigations) in the Taihu Lake Basin of East China were observed and then evaluated using Hydrus-1D model during two consecutiv...
