Identifying hydrodynamic soil parameters of Hweez dam in Lattakia which needed to build mathematical model for Predicting the Water Content Distribution using the Simulation Program PCSiWaPro®

In this paper, we focus on the importance of conducting the necessary tests either field or laboratory in order to obtain realistic values for soil hydrodynamic parameters allowing the best result to simulate the actual situation of any engineering facility. The importance of this research highlights in earth dams and dikes which have great importance to economic, environmental and human. It is necessary to be complete accuracy when creating a mathematical model to study stability of these structures. From here comes the need to calculate these parameters rather than extracted from engineering codes, that we will use them to simulate the effect of long rainfall on the distribution of water content in the Hweez dam soil and hence its stability. We will build a mathematical model for dam using PCSiWaPro® depending on transition flow chart. concerning that, hydraulic conductivity and volumetric water content in the soil are functions of pore water pressure. These equations with their functions give a smooth transition of the studied model where the saturated state is considered as a special case of the used equations.

Changes in water content and dry matter in grains of some cereal crops during the period from anthesis to physiological maturity

This experiment was conducted at two ecologically different regions, Boka, and Gellien, using 3 lines of X.triticosecale Wittmack (372, C.187, and C.G.2) and 6 cultivars of wheat (5 of them were triticum durum Cham1, Cham3, Cham5, Bohoth5, and Haurani, and one of triticum aestivum Cham6), to assess the changes in water content and dry matter in the grains during the period from anthesis to physiological maturity .The results showed that all genotypes had the same moisture content curves, whereas it had seemed that the two durum wheat cultivars (Cham1 and Bohoth5) exhibited a disturbance in the moisture development curves in the first region, and the same observation was noticed on (Cham1, Cham3, and Cham5) in the second region. However, triticale lines had a higher test weight of 1000 grain compared with wheat cultivars in the two regions, and there was a positive relationship between grain fill duration and the weight of 1000 grain, whereas, there was a depression in the test weight of wheat cultivars in the second region in comparison with the first one, but it is associated with an increase of protein percentage, and this might be attributed to temperature elevation during grain fill stage.
