Analytical Solutions of Seepage into Ditches from Ponded Fields
Publisher: American Society of Civil Engineers
Abstract: A steady-state theory is developed for the seepage of ponded water into equally spaced drainage ditches in a homogeneous and anisotropic soil overlying an impervious barrier. Solutions are obtained for two general cases ...
Modeling Hydrological Processes in Hillslope Watershed of Humid Tropics
Publisher: American Society of Civil Engineers
Abstract: Hydrological studies were conducted in a lateritic hillslope watershed of Kerala, a humid tropical region in India. The watershed characteristics, soil moisture properties, and hydrological processes were evaluated. The ...
Ditch Drainage Theories for Homogeneous Anisotropic Soil
Publisher: American Society of Civil Engineers
Abstract: The problem of seepage of steady rainfall or irrigation recharge into a homogeneous and anisotropic soil medium, drained by equally spaced ditch drains overlying a barrier, is solved. Two general cases of the problem are ...
Theories of Ditch Drainage in Layered Anisotropic Soil
Publisher: American Society of Civil Engineers
Abstract: Approximate theoretical formulas are derived for predicting the water table position for steady rainfall or steady irrigation recharge into soil bounded by equally spaced ditch drains dug up to an impervious layer in ...
RS and Geographical Information System–Based Evaluation of Distributed and Composite Curve Number Techniques
Publisher: American Society of Civil Engineers
Abstract: This paper compares the composite and distributed curve number (CN) techniques in computation of runoff from a hypothetical watershed of
