Averages and coefficients of variation of the parameters of the van Genuchten equation were estimated, in relation to a large dataset, for soil particle-size classes differentiated according to the pr...
Water retention characteristics of peat and sand mixtures
peat - sand mixtures water retention
2008/11/10
The water retention characteristics of peat, sand and their mixtures has been investigated. The results obtained showed that the hydro-physical properties of the mixtures in- vestigated depended on th...
Using of geocomposite with superabsorbent synthetic polymers as water retention element in vegetative layers
geocomposite superabsorbent anti-erosion protection water retention
