  • A modified Green–Ampt model for water infiltration and preferential flow

    Preferential flow is significant for its contribution to rapid response to hydrologic inputs at the soil surface and unsaturated zone flow, which is critical for flow generation in rainfall–runoff (RR) models. In combination with the diffuse and source-responsive flow equations, a new model for water infiltration that incorporates preferential flow is proposed in this paper. Its performance in ...

  • Effect of soil texture on water infiltration in semiarid reclaimed land

    The infiltration of water and its influencing factors in disturbed or reclaimed land are not well understood. A better understanding would provide essential information for assessing the hydrological processes in disturbed ecosystems. We measured the infiltration of water in soils from loamy and sandy reclaimed land. The relationships between infiltration and soil properties were analyzed ...

  • Alternative methods to control water infiltration for landfills: a case study in the tropics

    Landfill caps made of synthetic materials are expensive. Compacted clay caps are also subject to desiccation cracks which negate the overall purpose of infiltration reduction. Vegetative cover caps, also called evapotranspiration covers, have been tested in arid climates. In this research, a vegetative cover using a naturally occurring soil of Hawaii was tested. As the annual rainfall at the site ...

  • Thatch and mat management in an established creeping bentgrass golf green

    Thatch is a layer of partially decomposed organic matter between green shoot tissue and the soil surface, and mat is thatch partially intermixed with topsoil. Excessive thatch–mat layering (>2.54 cm) is generally detrimental to turfgrass management, and numerous techniques including various mechanical and topdressing regimes, have been attempted to reduce its severity. This factorial ...

  • Impact of Tsunami Disaster on the Water Environment

    ABSTRACTThe earthquake that generated the great Indian Ocean tsunami of 2004 is estimated to have released the energy of 23,000 Hiroshima-type atomic bombs, according to the U.S. Geological Survey (USGS). The earthquake occurred on December 26, 2004 was an undersea earthquake originated in the Indian Ocean off the western coast Indonesia and generated tsunamis that were among the worst disasters ...
