Baru SMART watershed<\/p>\n

The Baru watershed is located in the Ulu Segama Forest Reserve, Sabah, Borneo. This small site has been subject to ongoing hydrological experimentation since 1990 and is part of the Danum Valley Field Centre Hydrology Project<\/a>. This link<\/a> gives details of the many projects that have been undertaken at the site. The site is part of the Critical Zone Exploration Network<\/a>. In June 2015 the site was equipped with an RX3000 remote monitoring station to deliver rainfall and streamflow data via telemetry. In addition, a trial was performed with SMART sensors<\/a> for high frequency measurement of water quality variables in the Baru stream.Location of the site can be found on our interactive map<\/a>.<\/p>\n
