Comparison of quadratic and non-linear programming (QP and NLP) optimization models in groundwater management
Psilovikos, A.; Tzimopoulos, C. (2004)This project is concerned with the comparison of two algorithms used in groundwater management models based on Quadratic Programming (QP) and Non-linear Programming (NLP) models,. A quadratic objective function is used and ... -
Estimation of unsaturated flow in layered soils with the finite control volume method
Arampatzis, G.; Tzimopoulos, C.; Sakellariou-Makrantonaki, M.; Yannopoulos, S. (2001)Water movement in unsaturated soil is described by Richards' equation, which is strongly nonlinear and cannot be solved analytically. For this reason numerical methods such as finite difference and finite element methods ... -
Laboratory experiments and estimation of cumulative infiltration and sorptivity
Angelaki, A.; Sakellariou-Makrantonaki, M.; Tzimopoulos, C. (2004)Soil water cumulative infiltration affects the environment by controlling the irrigation rate and consequently the water and pollutants movement through the ground. In order to study the cumulative infiltration in a sandy ... -
Theoretical and Experimental Research of Cumulative Infiltration
Angelaki, A.; Sakellariou-Makrantonaki, M.; Tzimopoulos, C. (2013)The main object of this study is the comparative evaluation of Green & Ampt's (G & A) and Parlange's (P's) models and their ability to describe cumulative infiltration of water through various soil types. Three soil samples ...
