Abstract
The development of GIS brings several advantages for environmental protection and management in Binh Dinh province. This technology has huge potential to overcome the disadvantages of ground-based monitoring sites and can provide additional information on the geographical representation of environmental quality at the regional level. The objective of this study is to use GIS technology to develop a map for rapid identification of the emission coefficient Kv (Kv), coefficient Kq of receiving water (Kq), and wastewater discharge with columns A and B in national environmental regulations. This study also used the ArcGIS tool and map overlay method to merge data with several GIS’ layers. The results show the maps of emissions coefficient Kv in the province are as 5 regions with a coefficient Kv = 0.6; 0.8; 1.0; 1.2; 1.4 based on the current state of urban development, socio-economy, industrial zones, special-use forests, natural heritages, historical and cultural relics, urban areas, rural areas. For the coefficients Kq (Kq = 0.9) corresponding to the flow rate (Qmean) of receiving water of all rivers, streams, canals, and channels in Binh Đinh province (Qmean < 50 m3/s). The other result shows that the wastewater river basin from the downstream of the river to the estuary or lagoon usually is the zoning of wastewater discharge column B.
