Like many other nations, Morocco is grappling with escalating water stress, exacerbated by climate change, decreasing rainfall, and the increasing demand for water, particularly within the civil engineering sector.
While many studies explore ways to reduce freshwater consumption in civil engineering, few specifically address the use of seawater in concrete production.
The development of solutions that use seawater for concreting have been studied by several players in civil engineering.
The idea of using seawater in civil engineering, in the Moroccan context, could indeed be explored as an innovative solution to the scarcity of fresh water.
In the civil engineering sector, water is used at several stages, notably in the preparation of concrete for mixing, soil compaction and equipment cooling.

Structural Modal Parameter Identification Based on ARMA Model Qiang Pei 1,a, Long Li 1,b 1Research & Development Center of Civil Engineering Technology,Dalian University,Dalian 116622,China apqiem@163.com，bdxl269@163.com Keywords: ARMA model; building materials and structural engineering; parameter identification; seismic engineering Abstract.
Structural parameter identification is a significant technology to show certain characteristics and material damage of earthquake resistant structures or building materials in structural engineering and seismic engineering field.
It is based on the input and output of the monitoring data of the civil engineering structure to establish the mathematical model of the dynamic responses [1].
Accordingly it can provide a reliable basis for reinforcement, repairing, health diagnosis, testing and evaluation of building structures and the materials in structural engineering and seismic engineering field.

Equipped with mechanical conveyance system, the system can be applied to the civil engineer.
So rock stratum displacement is the key parameter [1][2] in geotechnical monitoring or civil engineer, which is one of the key aspects of stable dam structures.
The engineering disaster will be reduced if the engineers adopt effective arrangement according the measuring results of the displacement monitoring system.
If the displacement is exceed to the engineer standard, the engineering accidents would rise.
Engineer can tuning grouting pressure without delay and reduce the displacement according system information.

By setting finite electrodes on the edge of the sensitive layer, the stress field of tested structure is transformed to electric field which is apt to be tested, and with resistivity tomography technology (ERT), field(global) monitoring on civil engineering structure can be realized.
Introduction With development of smart materials and sensor technology, it is possible to diagnose and supervise security service characteristics of critical civil engineering [1].
With conductivity and piezoresistivity of smart materials and resistivity tomography, it is hopeful to realize visible field monitoring on civil engineering structure.
Generally, in researching methods of civil engineering structure health monitoring and diagnosing, in order to get rich experiment data, it is necessary to conduct a large number of simulation experiments with different sensors parameters and complicated loading condition; but they were usually limited by the hardware condition, model structure difficulty and resulted in large consumption of resources.
To study on civil engineering structure health monitoring and avoid impact resulting from measuring difference caused by misc factors in experiment, virtual experiment becomes the first solution.
