This new short course from NGWA will introduce you to urban groundwater elements as a basis for managing urban groundwater development, implementing effective urban groundwater planning practices, and developing urban groundwater policies.
Urban water budgets are often poorly understood. A misunderstanding of the sources, quantity, and quality of urban recharge can lead to counterproductive land-use decisions and misguided legislation. Groundwater impacts from urbanization often focus on increased runoff from impervious surfaces, which is sometimes incorrectly equated with reduced groundwater recharge.
Most groundwater modelers assume the opposite is true — urbanization increases groundwater recharge — and this assumption is backed by a number of studies that suggest urbanization increases recharge even in moderately humid areas.
In addition to the incidental recharge increases seen from urbanization, many communities now promote practices that promote focused, intentional recharge and infiltration. The benefits and disadvantages of these focused infiltration practices must be analyzed in the context of a well understood urban water budget.
Infiltration can serve as one of the most effective and efficient best management practices to mitigate the environmental impacts of stormwater disposal/management. Low impact development, or LID, technologies, whether bioswales, porous pavement, or rain gardens, often rely on infiltration to achieve their stormwater management goals.
Unfortunately, however, many planners, architects, and design engineers take infiltration for granted. Generally because infiltration takes place out of site, it is therefore out of mind. Many program management plans and specific site developments get mired in a number of project feasibility problems because the project or agency planning teams do not have a clear understanding of the limitations and most importantly, the inexactness of infiltration technology.
