It refers to the ability of a system or area to handle or remove excess water. Example: The new drainage system has greatly increased the city's drainage capacity, reducing the risk of flooding during heavy rains.
But how much drainage capacity is enough?
The risk of flooding was rationalized away by designing drainage capacity into the subways.
The national water authority declined to comment Sunday, but an assessment published on its Web site found that the decreased drainage capacity of the Hungarian flood protection system was due largely to increased building on former floodplains along rivers.
Planners will consider flood risk, highway access, and the sewerage and drainage capacity of possible sites.
This can occur through soil compaction or erosion, or increase in drainage capacity (Bruijnzeel [1990]).
The experiments included short-term and long-term water-tightness as well as drainage capacity tests.
The improved drainage capacities of that infill material mean that only an eight-inch crown is required, as opposed to 30 inches on older fields.
The rainfall led to flash flooding, which inundated roads and cars and overwhelmed local drainage capacities.
In fact, vermicomposts are finely divided peat-like materials with high porosity, aeration, drainage, water holding capacity and large surface area, providing strong capacity to hold and retain plant available nutrients such as nitrates, exchangeable phosphorus, soluble potassium, calcium, magnesium etc. (Edwards and Burrows 1988; Orozco et al. 1996; Chaudhuri et al. 2000).
Vermicomposts (VC) are finely divided, peat-like materials with high porosity, aeration, drainage, water-holding capacity, and microbial activity (Edwards 2004; Pandya et al. 2014).
Furthermore, the improvement of drainage and storage capacity in the upstream rural area is able to alleviate the extent and magnitude of flooding in the downstream urban area.
