Rainfall impact is a research area that focuses on studying the effects of rainfall on various environmental aspects, such as ecosystems, agriculture, water resources, and infrastructure. Researchers in this field examine the relationship between rainfall patterns, intensity, and frequency, and how they influence these different systems. They may also investigate the impacts of extreme weather events, such as droughts, floods, and storms, on the environment and society. By understanding the effects of rainfall on different sectors, researchers can help to improve preparedness, resilience, and sustainability in the face of changing climate patterns.
