Limited similitude relations for the construction of physical models of the watershed hydrologic system have been developed, using dimensional analysis, by Mamisao and Chery. Tests on both constructed models indicate that the hoped for similarity did not materialize, and that further testing is necessary to develop empirically the needed similarity relations. Grace and Eagleson have, using differential equations, also developed similitude relations for hydrologic system modeling and discussed the limitations of such modeling. Other individuals are also contemplating modeling, but their endeavors are not concerned with similitude relations, because their devices are non‐scaled representatives of parts of the natural hydrologic system.
