  • Falling water tables` knock-on effect on falling harvests

    Scores of countries are overpumping aquifers as they struggle to satisfy their growing water needs. The drilling of millions of irrigation wells has pushed water withdrawals beyond recharge rates, in effect leading to groundwater mining. The failure of governments to limit pumping to the sustainable yield of aquifers means that water tables are now falling in countries that contain more than half ...

  • A distributed hydrological model in the Heihe River basin and its potential for estimating the required irrigation water

    A Grid-based Integrated Surface–Groundwater Model (GISMOD) was developed to estimate the required irrigation water using a control-site method. The entire catchment is divided into multiple grid cells of equal size, and several grid cells can be chosen as the control sites by users in this model. The grid cells from the upper stream of each control site, which have a land-use type of farmland, ...

  • Evaluation of the management practice for controlling herbicide runoff from paddy fields using intermittent and spillover-irrigation schemes

    Two water management practices, an intermittent  irrigation scheme using automatic irrigation system(AI) and a spillover-irrigation scheme (SI), were compared for the fate and transport of commonly used herbicides, mefenacet (MF) and bensulfuron-methyl (BSM) in experimental paddy plots. Maximum mefenacet concentrations in paddy water were 660 and 540 µgL−1 for AI and SI plot, respectively. ...

  • Building a filter defense against Zebra and Quagga mussles

    Tiny mussels can create massive problems for intake structures, vaLves, pumps, screens and other water infrastructure around the US. Some filtration systems can provide chemical-free protection against invasive zebra and quagga mussels, but it is vital to understand the problem and develop the right system to avoid being overrun by the alien species. Zebra mussels (Dreissena polymorpha) and their ...

  • Size‐dependent impacts of silver nanoparticles on the lifespan, fertility, growth, and locomotion of Caenorhabditis elegans

    The increased bioavailability of nanoparticles engineered for good dispersion in water may have biological and environmental impacts. To examine the present issue, we assessed the biological effects in nematodes as they relate to exposure to silver nanoparticles (AgNP) of different sizes at low (1 mg/L Ag), medium (10 mg/L Ag), and high concentrations (100 mg/L Ag). Over multiple generations, ...

  • BBA Pumps irrigation pumps, an unseen hero of daily life

    The Netherlands receives on average 800 mm of rain each year. This, you may feel is the reason why you relatively never see BBA irrigation pumps out in the field. But it is more likely due to the fact that the B series of irrigation pumps rarely sits idle. Due to their convenient mounting on a wheelbarrow frame they can be easily returned back to the barn as soon as the job is done. ...

  • Tensiometers—Theory, Construction, and Use

    Standard tensiometers are used to measure matric potential as low as -870 cm of water in the unsaturated zone by creating a saturated hydraulic link between the soil water and a pressure sensor. The direction and, in some cases, quantity of water flux can be determined using multiple installations.A variety of commercial and fabricated tensiometers are commonly used. Saturated porous ceramic ...
