Estimation of Hydrological Outputs using HEC-HMS and GIS [PDF]

Nigerian Journal of Environmental Sciences and Technology, 2017
Estimating runoff and understanding of the relationship between rainfall and runoff are of great importance in the management of flood. Several computer based hydrological models have been developed and used in simulating runoff in various watersheds in different parts of the world and in water resource studies. This study focuses on the combination of

Compatibility of personal care thickening polymers in sulphate‐free surfactants

International Journal of Cosmetic Science, EarlyView.
Phase behaviour for alpha olefin sulfonate surfactant 10–15 wt% combined with 1 wt% sodium carboxy methyl cellulose, clearly indicating the sensitivity in miscibility when adding various levels of background salt. Abstract Objective Formulators today know that when traditional surfactants and polymers are replaced new problems occur. What was before a ‘
