The construction of embedding piles in cross-section at Hualien River system was completed in 1978 with regard to the cross-section measuring results report where completed over the years in 1993, 2004, 2005, 2008 and 2011. The Council conducted "Hualien River Management Planning Review" and the preliminary results of the project range area includes of Hualien main river stream Mugua River, Shoufeng River, Wanli River, Maan River, Guangfu River and the other 10 tributary streams.

In order to meet the requirement of "Hualien River Management Planning (Amendment)”, the council executed measurement survey at embankment revetment, drain gate and water intake gate to update 1/1000 scale map to create new river map information in accordance with follow up the river management planning and engineering facilities. The surveillance area contained of confluence from Hualien River 1 mainstream and 10 tributary streams have completed total 174km of measurement survey at embankment revetment (Table 2-16), 32 gates of water gate surveillance (Table 2-17~18) and up to down streams of Hualien bridge total 233 hectare of topographic map revision (West up stream bank of the left embankment of the sugar factory at Hualien river, right bank embankment farm and east of detention of illegalize sand area about 106 hectare, right bank embankment index number 1 of Guangfu River and east of detention of illegalize sand area about 20 hectare, both sides of south Chingshui river detention of illegalize sand area about 37 hectare and up to down main stream of Hualien bridge area about 70 hectare). In addition, this plan integrates with past year’s aerial photographs, river water system, cadastral information, cross-section map of embankment results, coordinate with Google Earth Enterprise with procured Water Resources Agency to build 3D GIS showcase to show interactive information systems.
