General Site Description: 

Dong Cao is a small agricultural catchment (47 ha) of northern Vietnam, located at 70 km from Hanoi, in a sloping land environment. The objective is to monitor the impacts of land use changes (from cassava to fodder and tree plantations) and possible climate changes upon hydrologic and sedimentary budgets, fluxes and qualities. The catchment has an elevation of 125m to 485m and slopes ranging from 15 to 120%. Equipments include an automatic meterological station since 2001, 4 weirs to monitor discharge, suspended and bedload since 2001, automatic suspended load samplers. More information available on http://www.msec3.net/portal/ and in Valentin et al. (2008); Yen Tan Bui et al. (2013), Hydrol. Process. Dong Cao belongs to the MultiScale Environmental Changes Network (MSEC) which is a long term monitoring network of experimental catchments in South-East Asia (Laos, Thailand, Vietnam) and to the French SOERE-RBV Network.

Purpose of Site : 

The objectives of this MSEC site are fivefold: (i) monitor the impact of land use change and possible climate change upon the hydrologic and sedimentary responses at various scales from micro-plots (1 m²) under natural or simulated rainfall to micro-catchments (0.6 ha) and larger catchments (up to 60 ha); 'ii) conduct experiments on new agricultural practices and their impacts on hydrology, carbon, nutrients, pollution and erosion; (iii) provide sound data to the scientific community and to decision makers to improve land management of steep slope environment in South-East Asia; (iv) develop and test generic hydrologic and erosion models; (v) to train young scientists and students from a very wide array of disciplines.
