Capillary Rise in a Tube

Domenico and Schwartz, 1992.

Soil Water Characteristic Curve is

a Function of pore size

Capillary forces hold water tightly in small clay pores.

Larger sand pores produce lower capillary pressures.

Soil Water Characteristic Curve is a Function of

Sorting (Pore Size Distribution)

Relatively wide range of pore sizes from small to large results in widely varying capillary pressures.

Narrow range of particle sizes results in relatively small range of capillary pressures.

Fetter, 1999.

Who Was Darcy?

  • Henry Philibert Gaspard Darcy was born June 10, 1803 in Dijon, France.
  • Admitted to the French School of Bridges and Roads in Paris, part of the Corps of Bridges and Roads. After graduation, he was eventually assigned by the Corps to a position in Dijon.
  • In 1828, Darcy designed a 12.7 km system of aqueducts to supply the city of Dijon with surface water. The system included 28,000 m of pressurized surface lines and required no pumps or filters.
  • Made important contributions to flow and friction loss in pipes, created an improved pitot tube design, and was the first to postulate the existance of a boundary layer in fluid flow.
  • In 1856, carried out experiments while researching sand filters that lead to Darcy’s Law.
  • Died unexpectedly January 3, 1858 from pneumonia during a trip to Paris.
