2. Green Infrastructure as Disaster Risk Reduction Measure

Paddy fields and vegetation have been considered of great importance for their role as a green infrastructure (GI). As a disaster risk is a function of hazard, exposure, and vulnerability, the discussion was also accelerated on the possibility to reduce the exposure and vulnerability not only by grey infrastructure but also by green infrastructure such as forest, paddy fields, etc. In addition, for adapting climate change, GI has recently been applied to stormwater control elements and to control practices used to implement low impact development (LID). As the definition of GI is wide, this special session classifies the GI into the macro-scale topic (session1) such as watershed management and/or natural or hybrid (grey and green) system management, and the micro-scale topic (session-2) such as minimizing effective imperviousness to treat stormwater, etc.

Session 2-1: Ecosystem-based disaster risk reduction for floods and tsunamis

Objective
The effectiveness of coastal forests on sand dunes, mangroves or lagoon in reducing the disastrous fluid force of a tsunami has also received increased attention since the 1998 Papua New Guinea tsunami, the 2004 Indian Ocean tsunami, and the 2011 Great East Japan tsunami even though it had limitations (destruction) and disadvantages(production of driftwood). This session discusses the old wisdom of GI in Asia-Pacific region, proper design, and management of GI for increasing and strengthening the Ecosystem-based Disaster Risk Reduction (Eco-DRR) function. The macroscopic topic is welcomed in this special session.

Topics of interest
– Energy reduction of water-related hazards by natural system
– Management and/or rehabilitation of Eco-DRR function
– Function of forest belt as a GI against storm surge and tsunami
– Hybrid defense with natural system and artificial structures
– Utilization of paddy fields as flood retention basin for excessive flood under global climate change condition
– Re-recognition of the old Asian wisdom of utilizing natural or traditional landuse for disaster risk reduction

Session 2-2: Adapting to climate change using green infrastructure and LID measures

Objective
Green infrastructure (GI) in the urban area refer to systems and practices that utilize natural processes to infiltrate, evapotranspiration, or reuse stormwater on the site where the water is generated. Recently, GI has been applied to stormwater control elements and to control practices used to implement low impact development (LID). Considering that LID employs preserving and recreating natural landscape features, minimizing effective imperviousness to treat stormwater, many GI practices (i.e.,
bioretention facilities, rain gardens, bioswales, vegetated rooftops) can be implemented to achieve the goal of LID.

Topics of interest:
– Green infrastructure planning, design, construction and operations (especially in urban area)

– Green infrastructure and LID construction, and operations, and maintenance
– Adapting to climate change using green infrastructure and LID measures
– Modeling and tools for green infrastructure planning and design
– Green infrastructure and LID case studies

Representative keywords:
Micro-scale study, LID, climate change, stormwater, urban area

3. Conceptual ideas to solve problems related to Hydro-Environment Engineering.

This session is aimed at sharing ideas or concept that may be developed to solve problems related to Hydro-Environment and Engineering or Technology. You are invited to write your ideas or concept. You may build your concept based on existing science and technology with or without presenting any experiments or results to finally come to a conclusion about the prospect of your idea.

Target of participants:
Government officers, engineers (contractors, consultants), scientists (researchers, academicians)

Background:
A number of scientists and engineers may be very busy with administration works and teaching and they do not have much time, research facilities, or colleagues to realize their dreams of solving hydro environment engineering-related problems. Much of their ideas, however, may be worth to be shared in an international conference like IAHR-APD.

Objectives:
This session aims to share ideas/concepts on how to solve real problems related to hydro environment engineering fields. The paper may contain an introduction for problem statement and research objective, methodologies based on relevant science and technology, theories supporting the ideas, and a discussion how to realize the ideas. Hence, results from experiments or simulations are not compulsory for presentation. For instance: a problem statement is about water scarcity, and the objective is how to improve the water availability artificially. The methodology is to explain about the methods to achieve the objective. It is expected that the methods will be new ideas, innovation that have been never brought up before. A multidisciplinary method is recommended. Practitioners are also welcomed to share the weaknesses of current technology being used in daily works, and to propose how the technology shall be improved.

Goal:
It is expected that people who actually do not have time, money, and facilities to do research are able to share their ideas. It is also expected that at the end of the session, there will be collaboration among participants to implement the proposed ideas that sound realistic to be followed up.

Presentation time:
The presentation time can be different from the normal session. For this session, presentation time is approximately 8 minutes, and continue with discussion for 7 minutes.

4. Volcano and Multimodal Sediment Disaster:  Simulation and Risk Mitigation

The occurrence of  water and sediment related disasters are often triggered by extreem phenomena including the heavy rainfall, earthquake as well as active volcano. In order to reduce the negative impacts as caused by, efforts in developing simulation and other risk mitigation are considerably essential. The multimodal sediment disaster as triggered by volcanics activity should be well predicted, simulation of the phenomena through related integrated total monitoring system of volcanic activity and hydro-hydrological phenomena are relevant and important subjects to be presented and discuss in the 21th Congress of IAHRAPD.

Target of participants:
Researchers and policy makers related to volcanic activities including their impacts on the multimodal sediment disaster (simulation and application).

5. Hydrology-geomorphology Links in Tropical Rivers

Background:
The geomorphology of tropical rivers has received insufficient attention when compared to the advances realized by other scientific disciplines in the tropics. Science of the tropics has focused particularly on biodiversity in studies of terrestrial and aquatic ecology, which often lack a solid knowledge base regarding geomorphology and hydrology. Integration of hydrology and geomorphology will provide a solid conceptual framework of the functioning of the physical hydro system, enabling progress in each of the separate disciplines and in ecology. A key issue connecting hydrology to the geomorphological behavior of tropical rivers regards the hydrological exchange processes between a river and its surrounding aquifers, controlling river bank stability and the buffering effect of aquifers. Recent progress in hydrological modelling, in field instrumentation and in satellite remote sensing has opened the possibility to adopt a holistic approach to address the hydrologic and geomorphic aspects of large river basins.

Target of participants:
Academics, researchers, practitioners are welcomed to participate in this session. The topic of interest of this session includes methods for river monitoring and modelling, analysis of sediment transport and river morphology, and hydrological interactions in wetlands and in peat regions.

Objective:
The objective of this special session is to discuss the interlinked processes governing the hydrology and geomorphology of the tropical rivers, their deltas, wetland regions and peat lands connected to the rivers. This will yield new scientific insights in the fields of hydrology and geomorphology, which can be linked to aquatic ecology and form a solid basis for science-based water resources management and river engineering in the future. The gained scientific knowledge can be used among others to reveal main factors controlling drought, to analyze problems of flooding and salinity intrusion in the downstream lowland region
