What do runoffs from infrequent rainstorms create?

Runoffs from infrequent rainstorms can create erosion and sediment transport, leading to the degradation of soil quality and the alteration of landscapes. They can also result in localized flooding, which may damage infrastructure and disrupt ecosystems. Additionally, these runoffs can carry pollutants into rivers and streams, negatively impacting water quality and aquatic life. Overall, the effects of such runoffs can have significant environmental and societal consequences.
