As the TOC increases, what happens to the storm intensity?

• A. A. increase
• B. B. decrease
• C. C. cannot tell without a chart
• D. D. cannot tell without knowing the storm design frequency

Answer: (B)

When considering the relationship between total organic carbon (TOC) levels and storm intensity, it is important to recognize the hydrological processes at play. As TOC increases, it often indicates a higher level of organic material in water bodies. This can lead to an increase in the capacity of that water body to absorb rainfall and handle stormwater runoff. When TOC is high, the water's physical and chemical properties can change. Increased organic matter can result in enhanced soil water retention and infiltration. This means that during storm events, the soil may be able to absorb more water, potentially reducing runoff and modulating peak flow rates. It can lead to the absorption and slowing down of the rate of surface flow during and after storms. On the other hand, an increase in TOC can also sometimes contribute to changes in hydrological responses such as increased vegetation and root mass, leading to a more stable soil structure which similarly aids in stormwater management. However, these effects do not necessarily correlate with a direct increase in storm intensity; rather, they can help in mitigating the impacts of storm intensity through better water management practices. Thus, the correct choice reflects the understanding that as TOC increases, the inherent properties of the watershed can lead to a reduction in the
