I. General Information
A. Date
26-28 November, 2012
B. Venue
Pakkading District Administration Office, Bolikhamxay Province
C. Number of participants
A total of 26 participants attended the workshop, with two student interns of NT-NKD
RBCs who observed the workshop proceedings. The workshop participants, aside from the
Nam Theun-Nam Kading River Basin Committee Secretariat (NT-NKD RBCs) and the
Technical Working Group (TWG), are composed of different stakeholders of the NT-NKD
basin both from the public and the private sectors; some of which participated in the
Inception Workshop held on 20 November 2012 at Pakxane District in Bolikhamxay
Province. This time, however, representatives from Pakkading villages were also invited to
participate. The workshop participants were selected based on their close involvement
with the issue, i.e. flooding in the Pakkading District, and the communities that are affected
by the issue.
II. Objectives
The objectives of this workshop are to:
1. Formally introduce the PN25 RIU project “Companion Modelling (ComMod) at Sub-
Basin Scale” and the ComMod Approach to the stakeholders;
2. Co-construct the knowledge about flooding in the Pakkading District and use this
knowledge to collectively build the model support; and
3. Plan for the improvements of the model support, knowledge and stakeholder
involvement in the project process.
Based on the outcome of the Inception Workshop, this ComMod workshop will focus on
the issue of floods in Pakkading District because it was determined that drought was a
fairly new phenomenon, in which not much of the participants in the previous workshop
were completely aware or knowledgeable about drought in the area. The first ComMod
workshop was held for three days from the 26th until the 28th of November, 2012. Just like
the Inception Workshop, each workshop day was structured into five parts, namely the
Institutional Scope, Concrete Experience, Observe and Reflect, Analyses and
Conclusion (for the full tentative schedule, please refer to Appendix B of this document).
The workshop was mainly facilitated by Dr. Panomsak Promburom and assisted by Dr.
Pongchai Dumrongrojwatthana.

III. Methods and tools
A. Process design
Just like in the Project’s Inception Workshop, a Process Design was used to prepare the
content and structure of the 1st ComMod Workshop. In this case the 5 phases of the
workshop, namely the institutional scope, concrete experience, observe and reflect,
analyses and conclusion. However, since the workshop is for three days, these phases were
applied for each day. (Please refer to Annex B of this document for the Process Design of
this workshop).
B. Presentations
Although some participants in this workshop have attended the Inception Workshop the
previous week, there are new participants in this workshop who have yet to be introduced
to the project and the Companion Modelling approach. Therefore, PowerPoint
presentations were done in Thai/Lao language to introduce the project to the workshop
participants.
C. Modelling and models
The participants were introduced to the modelling approach and models with the
presentation of a simple model of the basin, which was gradually made more complex
throughout the workshop with the addition of new aspects/knowledge about the model. At
the beginning, a simple representation or model of the basin, a map showing the basic parts
of the NT-NKD basin. After preliminary discussions, new elements about the basin were
added – rain and erosion; this was shown as a PowerPoint animation. This animation
translates into the model support tool, a basin role-playing game with a paper game board
and various game peripherals (described further in Section IV of this document).
D. Group discussions
Using prepared discussion questions, the workshop participants were randomly grouped
to address the discussion questions. Three members of NT-NKD RBCs staff facilitated each
discussion group. Each group was then asked to present the results of its discussions to the
rest of the participants.
IV. Summary of Activities
A. Day 1
The first day of the workshop was opened by Mr. Thongma Souknavong, and the governor
of Pakkading District, Mr. Bounyu Phommavongsa, made the opening remarks. Similar to
the Inception Workshop held the previous week, the project was presented to the
workshop participants through the presentations of Dr. Panomsak Promburom. To
3
introduce modelling, Dr. Promburom guided the participants into a simple model of a basin
(Figure 1) which consisted of the river (light blue lines) and 3 dam cascades (light blue half
circular areas), upland (dark green), lowland (light green), upland farms (yellow).
Figure 1. Simple model of the basin
After the presentation, the participants were divided into groups to discuss and gather
knowledge amongst each other about the basin (Figure 2). To continue the process of
capacity-building, the groups were facilitated by Mr. Pounyasan Siphaphommachanh, Mr.
Xailee Xayaxang and Ms. Souksamone Latsachanh of NT-NKD RBC Secretariat. The groups
were given the task to determine several aspects of the dams, upland farms and lowland
areas:
1) Dams
a. Calendar of power needs
b. Calendar of water level
c. Constraints and difficulties in managing the dams
d. The strategy of water release (how do they decide when releasing water in
the dams)
2) Lowland area
a. Flood impacts
b. Strategies to avoid impacts
c. Constraints and difficulties
d. Land tenure system
3) Upland farms
a. Farming practice
b. Erosion impacts

more rain falling in the basin, but there is also erosion from the upland farms. The
sediments from the erosion in the uplands are then deposited to th

At this point, the model support was introduced to the participants. The model support
consisted of 2 gaming boards representing the Nam Theun (Figure 4a) and the Nam Kading
(Figure 4b). The other model support peripherals include rain and sediment tokens (Figure
4c), farm plots (Figure 4d) with the orange paper representing vegetables and the green
paper representing rice, road tokens (Figure 4e) and a rain sound maker (Figure 4f).

The model support was “played” with the participants (Figure 5) to represent two
situations, i.e. regular rainfall and heavy rainfall, just like in the animation presentation that
was presented earlier. In each situation, there was a game master to control the flow of the
game, two people played as dam managers who are in charge of managing the release of
water in the dams and the rest played as upland farmers or lowland farmers. The farmers
were asked to choose their farm plots in the game boards as well as the types of crops they
would plant, either rice or vegetables. The lowland famers, who have permanent plots,
wrote their names on their plot, while the upland farmers would change their plots after
each game cycle. A game assistant, Dr. Paolo Campo, would signify the coming of rain and
distributed the rain and sediment tokens onto the game board. He was also in charge of
moving the rain and sediment tokens on the game board to illustrate flooding and
sedimentation in the downstream. The participants also shared their knowledge on the
effect of floods on roads in the model.
Figure 5. Gaming sessions with the participants
After using the model support, the participants (in groups) were asked on how to
improve it (Figure 6), such as the representations that are used in the model support. After
the discussion, the workshop day was ended and would be continued the following day.
C. Day 3
The third day was started with the recollection of the previous day’s activities. After which,
the participants were involved in a discussion. The participants were asked to answer
“What are the possible effects of flooding?” and each participant wrote his or her answer on
a paper. Mr. Siphaphommachanh read the answers of each participant and was opened for
discussion. The complete list of answers is provided in Appendix C
To close the workshop, the participants expressed their enthusiasm and support for the
project and the ComMod process.

V. Outputs and outcomes
A. Knowledge-gathering
For the 1st day, the following was the output from the discussions:
1) Dams
a. Calendar of power needs
• Power generating period starts on December onwards
• Also, depends on the actual power demands
• In the case of Theun-Hinboun Dam, it release waters to the power
house at 110m3/s to generate 100 MW
b. Calendar of water level
• Between June/July-November.
• To get enough volume of water for the dry season, as planned
• During rainy season, the amount of water released depends on the
inflow volume which is varies according to the amount of rainfall
c. Constraints and difficulties in managing the dams
• Releasing too much water would cause negative impacts to
downstream area. (river bank erosion)
• If the amount of the stored water is less than expected level, this
would affect the power generation
• Incomplete knowledge and information on water volume and water
flow speed during the heavy rainfall or storm events
• Poor communication between local people and the dam manager,
especially in cases of emergency (unclear information, not on time,
cannot reach all the target)
• Rainfall/climate variability
d. The strategy of water release (how do they decide when releasing water in
the dams)
• During heavy rain/storm even, if the inflow amount approaches the
threshold (maximum) level, the dam will release the water with
warning in advance.
2) Lowland area
a. Flood impacts
• Crop damage
• Building and infrastructure damage.
• Economic disruption
• Diseases outbreak
b. Strategies to avoid impacts
• Move/migrate people and livestock to higher elevations
• Mitigation after the flood
• Reduce/suppress deforestation
• Proper dam management, proper amount of water released
• Dike construction
8
• Relocation, resettlement
• Improve warning and communication system
c. Constraints and difficulties
• Flood plain -> flood prone area
• Poor communication / warning system
d. Land tenure system
• Permanent ownership, with land title
3) Upland farms
a. Farming practice
• The main crops in lowland area are paddy rice, maize and others
• Some tree plantation
• Animal rearing
• Swidden agriculture
b. Erosion impacts
• Soil erosion
• Sedimentation in the streams
• Natural resource depletion
• Crop yield declines
• More farm labor required
• Land ownership exists, with land title
• Land allocation has not been well established
c. Constraints and difficulties
• Rainfall variability
d. Land tenure system
• Allocate land to local people and promote soil conservation practice
On the second day, the discussion yielded the following results. In the discussion, it was
pointed out that shifting cultivation in the highland area as one of the factors that cause
flash flood and magnifies the flood impact. In Pakkading district, about 60-70% of land is
titled. This implies that the rest of cultivated lands are in sloping/highland area with
shifting cultivation practice. Regarding dam management, in general during the rainy
season, the dam will try to store water in the reservoir to meet the power generation
requirements. The power generated during the dry season is about 30%-40% of the whole
capacity. During the rainy season, if the inflow of water is about to go over the reservoir
storage capacity, the dam will release the excess water. To do so, the dam would notify the
downstream communities three days in advance to prepare for the incoming water
released from the dam. The communication system consists of sending official documents
from the dam to the district office. In case of emergency, however, the dam will contact the
village head directly by mobile phone. In 2011, this notification system failed; local
communities were not informed on time, and thus faced severe flood impacts. The
participants further added that, nowadays, there are no gauges or water level monitoring
network system along the tributaries that connect to the reservoir and dam. Another
interesting aspect explaining the dynamic link between dam, land use and impact from
floods was that before the dam was constructed, flood was quite a common phenomenon
with less impact because there was not much agricultural land in the flood prone areas.
9
Nowadays, people keep expanding and intensifying the cultivated lands, thus they are
exposed to higher risk from floods. But it was also said that dams could help relieve the
occurrence of floods, as well as supply water to cultivated lands. Further discussion
suggested that the knowledge and data relevant to flood and its impacts are not fully
available or known. There should be further investigation/study/data gathering. While
each sector gathers and keep their own data, it can be managed by communicating or
contacting all the relevant sectors through the district authorities. This would make, for
example, the data and information from the dam easier to obtain.
B. Role-playing game
The workshop participants suggested making the following changes and improvement:
1. Instructions of the game and materials should be provided.
2. Better legends e.g. direction, colors (of icons/tokens) of different land use types
(rice, cassava, maize, etc), direction of the stream/river flows.
3. Add tree plantation on the map.
4. Define appropriate proportion of different land use types.
5. Change how flood and sediments spreads in the river, i.e. sediments are deposited at
the bottom of the river and that the water overflows on the banks of the rivers
before slowly spreading to the built-up areas in Pakkading.
6. Change the representations of farms (produce) to something that is more
identifiable instead of using orange and green post its.
7. Real players should be invited to play the game. Additional role/players were
suggested e.g. dam manager, trade and industrial sectors, district / provincial
authorities.
C. Impacts of flooding in the basin
(Listed in Appendix C)
VI. Lessons learned
At the end of the day, it was found out that the number of upland farms in the NT-NKD
basin have increased considerably and are thought to be one of the main factors of the
increase of the severity of floods. It was also found out that the dams are designed such that
some of the sediments that settle in the head ponds of the dams are released downstream.
It was also observed that during the use of the model support, the participants were very
enthusiastic in participating in the activity.
It was clear among all participants that, at the moment, the data/information that are
available and obtainable at the village level and the district offices is about 50% and 60-
70%, respectively. Therefore, this should be improved through collective efforts among all
sectors. During the moment of closing address, all participants agreed to continue
studying/investigating this flood issue using Pakkading as the pilot site.
10
VII. Suggestions / recommendations for improvement
Towards the end of the workshop, the participants thought that this modelling process
would be most useful if it was brought closer to the ground, i.e. to the communities. It was
then decided that the participants were to select one or two villages in the Pakkading
District in order to study more closely the effects of floods. This task was to be completed
such that it would be the main theme of the second ComMod workshop.
