context_page_description: Bishan-Ang Mo Kio Park is a major park in Singapore, located in the popular heartland of Bishan. Serving the residents of Bishan and Ang Mo Kio, the park sits entirely within Bishan, running along the Ang Mo Kio–Bishan boundary line, which is situated at Ang Mo Kio Avenue 1. In the middle of the park lies the Kallang River, which runs through it in the form of a flat riverbed.
context_section_description: The use of soil bioengineering techniques (a combination of vegetation, natural materials and civil engineering techniques) to stabilize the river banks and prevent erosion was a first for Singapore and is a new reference for soil stabilisation in the tropics, which have otherwise rarely been used or documented.
  In 2009, a test bed was constructed, testing about 10 different soil bioengineering techniques and a wide variety of tropical plant species along a length of 60 metres at one of the side drains in the park. Seven of these techniques were then selected for use along the main river. These include fascines, rip-rap with cuttings, geotextile wrapped soil-lifts, brush mattresses with fascines, reed rolls, planted gabions, and geotextile with plantings. The test bed was used to refine the selection of appropriate techniques and plants, as well as the most efficient and effective construction methods. Extensive systematic testing was carried out, including measuring the depth and tenacity of root development.
