Two Creek confluence The Maple Hong Kong, Maple Harbour flat and open, and an altitude of 110m to 300m or so, the main distribution area of fertile farmland fertile soil. Upstream of the project for the Maple Ridge Reservoir, the regions in which four distinct seasons, the Rainy Season, non-flood season with little precipitation, river training works, construction lines, north-south longitudinal, mostly single shore (single line) layout. Hong Kong Maple River Valley for many years lack of governance, worsening river erosion, and began to break down part of the revetment, the regional flow of soil is increasing year by year, and no revetment protection, when flash floods due to soil erosion led to river siltation serious, serious impact on watershed water quality and normal production and life of the basin near the village. Maple Harbour Basin to governance in order to protect
