Given below are two statements: Assertion (A): The information that is essential for any drainage investigations are topographic maps, soil survey and geological report, well logs and water table fluctuations, irrigation and drainage maps, climatological and meteorological data and information regarding irrigation methods. Reason (R): The reconnaissance survey consists of moving around the area, inquiries from local people and to locate on the base map information about physical boundaries, cropping conditions, etc.

The downward and lateral movement of water into the soil is called:
