It works better compared to the traditional water quality objective function and can be used in the engineering practice.
Among the engineering measures to improve the water quality in the plain river network and lakes, water diversion project has been becoming one of the most important measures in China before the pollution sources can be effectively controlled, such as Suzhou River in Shanghai[2], Foshan River in Guangdong [3] and Tai Lake basin [4].
Some environmental policies and engineering measures have been developed gradually to improve the water quality in the rivernet [14-15], such as the policies for controlling the pollution sources, the engineering measures of dredging and the water diversion project.

With regards to construction industry in Pakistan, which is constantly connected with various worries and difficulties for the engineers and now and again they attempted to sort out and often it has been overlook because of amateurish perspectives.
As the only regulatory body, the Pakistan Engineering Council (PEC) has yet to enforce health standards to be followed by construction stakeholders (Farooqui et al., 2007) [13].
PEC additionally puts together well-being training classes and required short seminars on proceeding with proficient turn of events (CPD), which are just accessible for engineers.
· The Pakistan Engineering Council ought to take the lead by setting up seminars and health and safety training courses for contractors.

Evaluating the Use of Waste Materials in Building Envelopes for Energy Efficiency: A Theoretical and Empirical Study Christena Kamal Hanna1,a*, Abdel-Monteleb Mohammad Ali2,b, and Sayed Shebl Mohamed Shebl3 c 1Architectural Engineering Department, Faculty of Engineering, Assiut University, Egypt 2Architectural Engineering Department, Faculty of Engineering, Assiut University, Egypt 3Housing & Building National Research Center, Cairo, Egypt aarchkristenakaml2030@yahoo.com, bmonteleb@gmail.com, cbsayed_shebl@yahoo.com Keywords: Design-Builder (DB), Simulation, Verification, building envelope, waste material, Thermal Performance, Indoor Temperature.
With the increasing interest in energy-efficient building design, building energy simulation programs are increasingly employed in the design process to help architects and engineers decide which design alternatives save energy more.
Engineers need software tools that can be used in both the conceptual design stage, when little is known about the building; and the last design stages.
