Butibum River Basin Management

Abstract: Following severe flooding of the Butibum River near Lae, Papua New Guinea, on 24th September 1983, which caused widespread property damage, loss of life, and rendered thousands of people temporarily homeless, extensive investigations were undertaken to try to avoid any recurrence of similar disasters. The 1983 flood discharge was estimated to be 830 m3/sec equivalent to a 1 in 50 year return period flood. Lae, which is bisected by the Butibum River, is the second largest city in PNG with a population in excess of 70,000 which is expected to increase to over 130,000 within the next 15-20 years. The river has a total catchment area of 110 km2 extending 20 km inland into the Atzera Ranges. As the engineering investigations and other related regime design aspects progressed a change in emphasis was found to be necessary. Since 1942 the river has eroded its banks and wandered in a relatively random manner. Therefore non-structural measures (planning regulations) together with financial and social constraints were combined with engineering measures. The investigations concluded that it is possible to establish a river basin management concept and river engineering works which will not only prevent future disasters but also provide positive economic, social and land gain benefits to the river environs and the community. Some key elements of the recommended scheme are being implemented at the present time.

STORM-Rhine: Simulation Tool for River Management

Abstract: The Simulation Tool for River Management (STORM), based on the River Rhine case, aims to provide insight into river and floodplain management, by (1) raising awareness of river functions, (2) exploring alternative strategies, (3) showing the links between natural processes, spatial planning, engineering interventions, river functions and stakeholder interests, (4) facilitating the debate between different policy makers and stakeholders from across the basin and (5) enhancing co-operation and mutual understanding. The simulation game is built around the new concepts of “Room for the River”, Flood Retention Areas, Resurrection of former River Channels and “Living with the Floods”. The Game focuses on the Lower and Middle Rhine from the Dutch Delta to Maxau in Germany. Influences from outside the area are included as scenarios for boundary conditions. The heart of the tool is the hydraulic module, which calculates representative high- and low waterlevels for different hydrological scenarios and influenced by river engineering measures and physical planning in the floodplains. The water levels are translated in flood risks, navigation potential, nature development and land use opportunities in the floodplain. Players of the Game represent the institutions: National, Regional, Municipal Government and Interest Organisations, with interests in flood protection, navigation, agriculture, urban expansion, mining and nature. Players take typical river and floodplain engineering, physical planning and administrative measures to pursue their interests in specific river functions. The players are linked by institutional arrangements and budgetary constraints. The game particularly aims at middle and higher level staff of local and regional government, water boards and members of interest groups from across the basin, who deal with particular stretches or functions of the river but who need (1) to be better aware of the integrated whole, (2) to understand the interests and considerations of others and (3) to experience the mutual benefits of co-operation. There is potential for using the game as one of the tools in support of interactive formulation of policy and participatory decision-making in actual plans.

Study on Evolution of River Bed and Flood Prediction at Lanzhou Section of Yellow River

Abstract: Yellow River through Lanzhou city, so flood prevention is a very important for Lanzhou city. On the basis of the hydrologic data from 1951 to 2011 year, using river engineering model experiment, design flows and design flood hydrograph of Lanzhou section of Yellow River was simulated. On the basis of the hydrologic data from 1951 to 2011 year, evolution of river bed at Lanzhou section of Yellow River was analyzed. Sedimentation has been increasing slowly since 60 years. By the river engineering model experiments, a river-dredging plan, river width is planned 300 m, had been put forwarded. And the design flood level and water surface profile in different design flood (5600 m3/s,6500 m3/s,7920 m3/s,8350 m3/s) of Lanzhou section are gotten. It is forecast that occurrence of deluge is possible.
