Urban Planning & Design Masterclass Banjarmasin 2015 focused on "Urban Water Challenges in Developing Countries". The presenter discussed rapid urban growth and associated issues like inadequate basic services and environmental degradation in developing countries. For Banjarmasin, issues discussed included insufficient water supply and sewage management, solid waste dumping in rivers, and associated flood and public health risks. The presenter proposed a three-part Integrated Flood Risk and Drainage Management Plan for Banjarmasin including short-term rehabilitation, medium-term data collection and modeling, and long-term investment strategies based on flood risk levels.

Floodplain Modelling Materials and MethodologyIDES Editor
A floodplain is the normally dry land area adjoining
river or stream that is inundated during flood events. The
most common reason for flooding could be overtopping of river
or stream due to heavy downfall. The floodplain carries flow
in excess of the river or stream capacity. Flood frequency and
flood water-surface elevations are the crucial components for
the evaluation of flood hazard. This paper presents the
methodology that incorporates advanced technologies for
hydrologic and hydraulic analyses that are needed to be carried
out to predict the flood water-surface elevations for any
ungaged watershed.
Floods can be hugely destructive, but they also offer opportunities for farmers and fisherfolk. If their frequency and extent can be measured, then we will be better able to mitigate costs and maximise benefits. Digital geospatial flood inundation mapping is a powerful new approach for flood response that shows floodwater extent and depth on the land surface. IWMI research will evaluate this new technology and develop a prototype flood inundation map for South Asia. Also discussed is a project to flood map and model in a spate irrigation system in Sudan.

3. Urban Development: Key Issues
Source: Asian Development Bank - Urban Development: Issues & Challenges
• Rapid urban population growth: 2008, > half world population lived in urban areas
(3.3 billion people) . 2030, expected almost 5 billion. Most of this growth will be in
developing countries. Urban population of Africa and Asia expected to double between
2000 and 2030 (UNFPA, 2007).
• High urban poverty level: Almost 25% of Asia's urban population is poor.
• Inadequate basic services: Large number of Asian cities cannot adequately provide
urban basic services. < Half of the cities population is covered by water supply. A
number of cities do not have efficient systems of solid waste collection. Majority of the
cities do not have sewerage system connections, and sanitary landfill facilities.
• Environmental degradation: With an increasing population density, especially in slums
areas, environmental and health problems are rising as well as concerns in managing
the consumption of non-renewable resources.

Sanitation Approach
WATER SUPPLY Management: Coverage of 98% of city population!
However, daily dotation (l/person/day)? Sufficient for essential domestic
uses (food, bathing, washing, toilet and leakage)?

8. IFR&DM Plan
Main Flood Risk and Drainage Problems in Banjarmasin?
1. Insufficient drainage capacity for dealing with Existing Flood Risk:
High urban flood risk from insufficient conveyance and
storage capacity of existing drainage canals system
(dumped solid waste, siltation, invasion and reduction of
main rivers and canals) → Short-term action
High urban flood risk from insufficient protection against
sea and rivers levels affected by Ndal movements →
Medium-long term solution → “IFR&DM Plan ”

2. Insufficient Drainage Capacity and Flood Protection for dealing with
potential increased Future Flood Risk from several risk sources:
Climate Change Impacts (Increasing sea levels and
probability storm events of high intensity) → Medium-long
term solution → IFR&DMP
Increased Population (people potentially affected byIncreased Population (people potentially affected by
floods, increasing urban runoff and solid waste generation)
→ Medium-long term solution → IFR&DMP
Increased Level of Development – Industrialization
(Higher Costs from flooding, Increasing deforestation
process, sedimentation in rivers and main channels, natural
runoff) → Medium-long term solution → IFR&DMP
