Urban hydrographs tend to be more flashy than non-urban hydrographs, driven mainly by the prominence of non-permeable surfaces. Websoils are a major store of carbon within the terrestrial carbon system. Stocks are usually expressed in units of mass. e.g. total global soil carbon storage is estimated at 1500-2400 PgC (PgC is petagrams of carbon, a unit equivalent to grams or one gigatonne.) Fluxes are measurements of the rate of flow of material between the stores. Because

WebV = K * i. (where V is the velocity of the groundwater flow, K is the hydraulic conductivity, and i is the hydraulic gradient). We can apply this equation to the scenario in Figure 14.5. If we assume that the permeability is 0.00001 m/s we get: V = 0.00001 * 0.08 = 0.0000008 m/s. That is equivalent to 0.000048 m/min, 0.0029 m/hour or 0.069 m/day.
