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.

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

A Natural Harmony

Conventional RCRA Subtitle D landfill covers include a composite hydraulic barrier in the cover system. However, many landfills use an alternative water balance cover that employs water storage mechanisms instead of a low-conductivity barrier.

With its moderate climate and warm, dry summers, California is a major agricultural producer and exporter. In 2007, California agricultural receipts topped $36 billion, with grapes, lettuce, and almonds as the top revenue-producing crops. Given that most of the state’s crops are irrigated, water drives California agriculture. However, a growing
