Abstract: The subsurface drainage operation of shallow soils is characterized by sudden and brief peak flows followed by long‐lasting tail recessions. A field experiment was conducted on a seasonally waterlogged, shallow loamy soil ...

Abstract: Semianalytical transient equations describing the behavior of water tables in subsurface drained soils when drains rest on a sloping impervious barrier have been derived previously and represent the bases of the SIDRA ...

Abstract: Semianalytical transient equations for shallow subsurface transverse drainage systems installed in sloping lands are developed. They provide a general relationship between drain flow rates, water table elevations, and ...

Abstract: A coupled model was used to simulate the hydrology of a 22 km
