Soils can process and contain considerable amounts of water. They can take in water, and will keep doing so until they are full, or until the rate at which they can transmit water into and through the pores is exceeded.

Managing for Drought

Managing for Drought

The mania for a green lawn, or in some cases green anything, across many regions of the US has been quelled by recent droughts (thankfully now abating). Even long before water meters were spinning at record rates for golf resorts, private homes, and corporate campuses, scientists have been devising technologies

Stormwater Irrigation

During recent decades there has been a growing national recognition that shrubs and trees in urban landscapes have both environmental and socioeconomic value. Research has shown that vegetation along streets and parking lots can lower urban temperatures and energy consumption (Halverson and Heisler 1981, Scott et al. 1999); filter, degrade,

Foliar Rainfall Factors

Foliar Rainfall Factors

Trees and forest systems play an important role in the water cycle by intercepting rainfall and regulating water flow to the soil for more efficient stormwater infiltration. Traditional urban development practices have reduced the function of these systems by eliminating the vertical structure (tree canopy cover), removing existing ground cover

Optimizing Irrigation

Optimizing Irrigation

Commercial growers, property managers, and landscapers can attest to how sophisticated and beneficial irrigation monitoring has become in terms of optimizing water consumption and plant growth, and maximizing operational profitability. Two examples from California—where much of the nation’s food supply is produced but where water availability remains a critical public

Leaves: The Fulcrum on Which the Water Balance Rests

Leaves: The Fulcrum on Which the Water Balance Rests

The hydrologic cycle is an interwoven network of dynamic equilibria of water in all its physical states driven by the Sun. The incoming solar radiation is all the energy available to cycle water through the air, land, and plant life by technology of the green leaf. An exploratory evaluation of

Urban Floodplain Management

Urban Floodplain Management

Flood events cause more than 3.5 billion dollars, or 90%, of property damage in the United States every year (FEMA 2009). Since 2004, more than 40% of annual natural disasters in the US have been related to flooding. With increasing local, state, and federal expenditures for flood disaster relief, flood

Farmland and Fecal Coliform

Farmland and Fecal Coliform

Fecal coliform transport on agricultural land can vary greatly with precipitation, livestock densities, and other environmental considerations. Various studies have discussed the effectiveness of different conservation practices for reducing fecal coliform loads on streams and subsurface water. These studies all conclude that grass buffers, along with other support practices, can
