Grassed filter strips in farm fields help reduce runoff and erosion by slowing water velocities in the vegetated areas. Grassy strips also reduce erosion by trapping excess sediment, nutrients, and farm chemicals. Vegetation (including dead vegetative materials) in prairies, forests, and other natural areas plays a similar role.

The soil surface acts as a filter that lets water pass through (infiltrate) at a rate known as the infiltration rate or infiltration capacity. Runoff may be produced when precipitation or snowmelt adds water to the soil surface faster than it can be absorbed. The excess water remains on the surface and flows downslope as runoff. For example, if the precipitation rate is 5 centimeters (about 2 inches) per hour, but the infiltration rate is only 2.5 centimeters (about 1 inch) per hour, surface runoff is produced at the rate of 2.5 centimeters (about 1 inch) per hour, even if the soil is not entirely saturated. This mechanism of runoff generation is more common in drier climates where vegetation cover is sparse.

In humid areas with greater vegetation cover, the water table may lie at the surface in low-lying areas or slope hollows, so that the soil there is saturated. Saturated areas expand during rain or snowmelt, as well as during the cold season when plants withdraw little water from the soil. Any rain that falls on these saturated areas must run off over the surface. In times of prolonged heavy rainfall, large areas of a gently sloping landscape may become saturated, and much of the rain that follows runs off rapidly to streams. This was the case during the devastating Mississippi River flood of 1993, when much of the landscape in the Upper Mississippi River Basin appeared as a "lake" on satellite images that detect surface water.

Soil Characteristics.

Infiltration rate is controlled by the nature of the soil, by the plant and animal communities it supports, and by human influences. Where soil is absent and little-fractured bedrock is exposed, water cannot soak in and will run off rapidly. If soil is present, but is very fine-grained and clay-rich, the pore spaces that water must pass through are extremely small; hence, water will infiltrate very slowly compared to sandy soils that readily soak up water. Some finer-grained soils have vertical cracks that form when the soil shrinks as it dries. These cracks allow water to enter more readily, but may close up after the soil is wetted.

Compaction of soils reduces the size of pore spaces and the infiltration rate. Water commonly runs off areas that were compacted through repeated passage of people, large animals, or heavy machinery. Raindrops falling on bare soil also can compact the soil surface in plowed fields, leading to increased runoff and erosion of farmland.

Ice and Snow.

Ice within the pore spaces of frozen soils typically reduces infiltration rates, but only soils that were saturated on freezing will completely prevent water from entering. Summer melting of the upper layer of permafrost in cold regions often results in a saturated zone of soil above the frozen ground.

Precipitation that falls as snow is stored until snowmelt, when a large pulse of runoff may be generated. Runoff occurs only after the entire snowpack has reached 0°C (32°F), some melting has occurred, and pore spaces between snow grains can no longer hold all the water supplied.

The rate of snowmelt depends on heat inputs into the snowpack through solar radiation and via water from melting and rainfall moving through the snow. The soil surface underneath the melting snowpack may become saturated, such that runoff flows through the base of the snowpack toward streams. Saturated zones and surface runoff commonly occur on slopes below the melting snow line .

Plants and Animals.

In general, plants and small animals tend to increase the infiltration rate of soils. Some water usually evaporates from plant surfaces before it can fall to the soil surface. A plant cover and litter layer of dead vegetation protects the soil surface from compaction by heavy raindrops, and also slows the delivery of water to the soil surface. Plant stems help slow down water that flows over the soil surface. Plant roots help create openings in the soil, and also draw water from beneath the soil surface and transpire it through leaves back to the atmosphere. Decayed plant matter helps keep fine soil particles (such as clay) from sticking together, thereby increasing infiltration capacity. The burrowing activities of small animals such as insects, worms, and gophers also help keep the soil loose and create small openings through which water can pass.

When the landscape is completely devegetated, for example, following a forest fire or during a construction project, a dramatic increase in runoff and soil erosion may result. In desert environments where much of the soil surface lacks vegetation and where bare rock is exposed, most of the rainfall in heavy thunderstorms runs off rapidly and flash floods are common. Yet in dense, humid forests, vegetation and thick, loose soils may absorb water so readily that water rarely runs off the surface.

Steep slopes in the headwaters of drainage basins tend to generate more runoff than do lowland areas. Mountain areas tend to receive more precipitation overall because they force air to be lifted and cooled. On gentle slopes, water may temporarily pond and later soak in. But on steep mountainsides, water tends to move downward more rapidly. Soils tend to be thinner on steep slopes, limiting storage of water, and where bedrock is exposed, little infiltration can occur. In some cases, however, accumulations of coarse sediment at the base of steep slopes soak up runoff from the cliffs above, turning it into subsurface flow.

Runoff and Flooding

Water commonly flows downslope through the loose soil overlying bedrock. This water moves more slowly to streams than does surface runoff and is Rain falling on areas where unfractured bedrock is exposed has little opportunity to infiltrate, and instead will run off the surface. A brief thunderstorm in Yellowstone National Park produced considerable surface runoff from these steep cliffs. much less likely to cause flooding, but is faster than the creeping flow of groundwater in the bedrock below.

Runoff and Urban Development

Urban development can greatly increase the amount of precipitation that is converted to runoff in a drainage basin. Most paved surfaces and rooftops allow no water to infiltrate, but instead divert water directly to storm channels and drains. Urbanization is of serious concern to water resources for several reasons.

First, the increased amount of water flowing to streams during storms causes larger floods, and floods build to a peak faster because of the rapid flow of water over smooth surfaces. Second, motor vehicles leave oils and exhaust residues on streets, and household and industrial chemicals also collect on pavement surfaces. These nonpoint-source pollutants are readily washed off during storms, contaminating streams into which urban runoff flows. Careless disposal of hazardous wastes on streets or in storm drains adds to the problem. Third, most precipitation has no chance to percolate downward to groundwater, so the supply of groundwater to wells is reduced.

Some cities have taken steps to reduce these impacts. Pavement can be constructed so that some water passes through to recharge groundwater, and storm runoff can be routed to artificial basins that allow water to soak in. Along with regulation of hazardous industrial wastes, programs have been developed to educate the public about the dangers of improper disposal of wastes on streets and in storm drains

Aquifer storage and recovery is a special type of artificial recharge of groundwater that uses dual-purpose wells for both injecting water into the aquifer and recovering (withdrawing) it later. Although the intent of AR generally is to increase groundwater storage for later use, incidental activities such as excess irrigation, stormwater disposal, canal leakage, and leaking water pipes may also result in AR.

Artificial recharge and aquifer storage and recovery are valuable water management tools that effectively help to offset increased demands for water. The variety of techniques, methods, and circumstances for these processes is vast and expanding.

Artificial Recharge

Artificial recharge requires some form of man-made structure. Surface spreading techniques involve keeping water at the surface in areas where the water can percolate down to a shallow, unconfined aquifer. Spreading basins, check dams in stream channels, furrows, trenches, and ditches are common AR examples (see Figure 1).

Surface spreading areas require periodic maintenance since the suspended sediment in the source water will settle out, clog the surface of the recharge area, and reduce the recharge rate. Microbial growth in the shallow soils also causes clogging. Many countries and most western states within the United States possess some AR projects that use some form of surface spreading techniques.

Injection techniques use wells to accomplish AR. Injection wells usually place water directly into a deep, confined aquifer where surface spreading would usually not work. Injection wells also require maintenance to remove particles, microbial growth, and chemical precipitates (solid substances).

Figure 1. Generalized cross-section of artificial recharge of groundwater using a surface spreading technique.

Injection wells are used in many countries. For example, such wells have been an important part of the water supply system in Israel since 1956. Society generally views the various AR structures as a more environmentally acceptable way to manage water rather than building dams for more surface storage. Yet the use of AR in any location still must overcome a variety of technical, legal, and financial obstacles.

Artificial recharge provides a tool to maintain or increase reliable water supplies. In some areas, agriculture and other uses have resulted in serious groundwater depletion. AR is important in these locations as a means of stabilizing the supply and sustaining withdrawals by wells. A large project in Los Angeles County, California recharges an annual average of 308 billion liters (80 billion gallons, or 250,000 acre-feet).

In some coastal areas, groundwater depletion can reverse the natural movement of groundwater to the sea and cause saltwater intrusion of the aquifer inland. In this case, AR provides a valuable hydraulic barrier that will likely prevent water quality degradation.

Site selection for AR is critical. Some aquifers hold little or no potential for successful AR projects, whereas others have great potential. Ideally, an aquifer will hold, store, and transmit desired amounts of recharge water without significant migration and chemical degradation of that water. In addition, the permeability of shallow earth materials should not limit the infiltration by surface spreading. Site investigation for AR should include hydrogeologic mapping of the aquifer to identify aquifer characteristics. Advanced techniques would use computer simulations for modeling groundwater flow and transport.

Water availability is often the most important consideration for the timing of AR. This occurs when the supply from the source is abundant and exceeds other demands. In most cases this involves strong seasonal weatherrelated influences, but it can also result during peak flow events or unusually wet years. Typically, AR by spreading techniques uses untreated surface water as its source. Injection techniques have used untreated water, treated drinking water, or reclaimed water, as appropriate for the site-specific conditions. The injection of reclaimed wastewater is a more constant supply and less dependent on seasonal availability.

Aquifer Storage and Recovery

Aquifer storage and recovery (ASR) may be defined as the storage of water in an aquifer through a well during times when water is available, and later recovery of the water from the same well (see Figure 2). ASR is a specific type of AR that involves potable water. The technique provides for specific placement of water in the aquifer and recovery of essentially the same water. Ideally, the recovered water will remain potable and not require additional treatment. ASR is generally pursued by cities.
