Ecological water allocation(EWA) is needed in the practice according to ecological water requirement of watershed recently,which means to protect and improve eco-environment after allocating appropriate water resource for ecosystem.

Research and application of dynamic water distribution model for secondary cooling section in slab continuous casting

The distribution dynamics of 95Zr absorbed in crucian and the behavioral trait of 95Zr in an aquatic ecosystem was studied by using isotope-tracer technology, and the mathematical model was confirmed by application of nonlinear regression method.

Conclude that the degree of effect about tail-water of surface water heat pumps on Aquatic Ecosystem is mainly decided in the quantity of effluent and the temperature difference between influent and effluent,and it also has close relation with the hydrology and geology quanlity characteristics of water resource.
