Climate change in many parts of the country is expected to increase the proportion of rainfall occurring in high intensity events, resulting in increased stormwater runoff. At the same time, a shift towards more intense storms is expected to decrease infiltration and groundwater recharge, resulting in reduced low flow periods between events. Increased air temperatures and evapotranspiration could also result in reduced streamflow between rainfall events. Reduced low flow events in receiving waters could result in increased water quality impairment below POTWs due to reduced dilution of effluent.
