Drainage strategies for offshore chemical industrial district considering environmental impact assessment
Considering the importance of offshore chemical industrial district,the flood control and drainage standards are relatively high.The original flood control and drainage plan for a techni-cal economic development area in Fujian follows the current drainage system and terrain layout.However,according to the new environmental impact assessment requirements,changing the posi-tion of rainwater discharge outlets will have a significant adjustment to drainage system.There-fore,it is necessary to analyze and explore the drainage problems under the new situation.After considering environment and the characteristics of the site,three relatively reasonable drainage plans have been proposed.Through design rainstorm and runoff model,a one-dimensional hydro-dynamic model of the study area is established to simulate the drainage level of each scheme,three drainage schemes are discussed through the hydraulic model.Finally,a reasonable drainage strate-gy is proposed considering the safety,economy and environmental friendliness.
