Evaporation control research, 1959-60
Water Resources Division, U.S. Geological Survey
1963, Water Supply Paper 1692
Two hundred and forty-five dispersions of long-chain alkanols were formulated by using various emulsifiers and alkanols. The dispensing and spreading ability of each of these formulations was tested. The most promising emulsifier that could be used with any of the alkanols was glyceryl monostearate (self-emulsifying). However, the concentration of the...
Factors influencing the occurrence of floods in a humid region of diverse terrain
M. A. Benson
