Discharge and Sediment transport assessment on Barito River, Banjarmasin, Indonesia by river engineers from Pakistan, Afghanistan, India and Indonesia

Banjarmasin, Indonesia

As a response to the 2010 devastating floods in Pakistan, UNESCO in cooperation with the Government of Japan has started a major project, "Strategic strengthening of flood Warning & Management Capacity of Pakistan" from July 2011 to September 2014 for improving the flood forecasting and early warning system of the country.

Under this project, International Centre for Water Hazard and Risk Management (ICHARM)/PWRI under the auspices of UNESCO and Japan Aerospace Exploration Agency (JAXA) have developed a model "Indus IFAS" and installed it at the Flood Forecasting Division in Lahore for test operation in 2014. However, the first phase of the project underlined the lack of field-measured data for more accurate simulations; in particular, river morphology data were not available during phase 1.

In addition to the River morphology data, it is important to understand riverbed variation during flooding. For this reason, basic data such as the river discharge and sediment transport assessment are necessary to be assessed. As one component of the project, ICHARM/ PWRI Hydraulics Engineering Research Group team led by Dr. Yorozuya Atsuhiro and Mr. Hiroshi Koseki, has delivered the "International training on River Discharge and Sediment Transport Assessment with ADCP" in Banjarmasin, Indonesia.

Twenty two river engineers from Pakistan (from PCRWR, all four Irrigation departments, Federal Flood Commission, Water and Power Development Authority, University Engineering Technology-Lahore, National University of Science and Technology Islamabad), Afghanistan (Kabul and Kandahar River authority), India (National Institute of Hydrology) and Indonesia (Ministry of Public Works) were successfully trained to use ADCP for river discharge and water and sediment samplers as well as analysis software from Hydro System Development (HSD). Awareness in Pakistan, India and Afghanistan has been raised on new technics for water discharge, bathymetric measurements and sediment transport rate.

Along with the training, water sampler, bed load dredger to sample river bed materials have been procured to PCRWR (Pakistan Council for Research on Water Resources) and raised their capacity to understand and allow the monitoring of sediment transport issues and their mitigation at terms.
