Rainfall-runoff, reservoir releases and modelled transfers can change Q, storage, levels, downstream travel and inundation.
One continuous Mekong world with three camera zones, 21 primary cities, 35 governed map assets, 57 blueprint additions, and an MHIE training inundation layer.

Mekong Flow Coordination Lab
Solo open world · Endless basinManage the Mekong Basin as One River Network
Every storm tests the whole river network system, roles and responsibilities. Forecast the inflow, coordinate pre-releases, protect communities, and keep energy productivity.
- 01Track the storm
See where rain will arrive and how much water it may bring.
- 02Coordinate the river flow
Time reservoir pre-releases so flood peaks do not cause impact downstream.
- 03Protect people & power
Warn communities, reduce flood damage, and maintain energy supply.
View your mission
Storms can arrive anywhere across the Mekong Basin. Each brings different rainfall, reservoir inflows and flood risks. Some storms may overlap, increasing the challenge.
Use forecasts, reservoir storage, release timing, community warnings and power planning to manage the river as one connected system. Your 75+ target is calculated only when you choose End Game & View Score.
Review the storm forecast, identify reservoirs at risk, and agree on the safest order and timing for releases.

- River flow changes when rainfall, tributaries and reservoir operations change.
- Warnings and field checks help people prepare; they do not change the river.
- The basin stays live, so review likely impacts before making a major decision.

Simulation guide
How does the simulation work?
Follow water through the Mekong, make coordinated training decisions and review their modelled or recorded consequences.
01
Start here
A five-step path for a first exercise.
- Orient while the basin lives.Use Zones to choose a basin view or point of interest; the simulation continues while you inspect and decide.
- Read the situation.Open Operations. Check the basin alert, current phase, priority assets and decisions due.
- Trace the water.Q is discharge. Q-ETA shows the routed flow pulse and its remaining display arrival time. Confluences add tributary and mainstream flow through MHIE.
- Make a decision.Select a plant, station, city or community. Review whether its action is modelled now or recorded for the exercise before applying it.
- Review live consequences.Every confirmed action recalibrates reservoir, energy, downstream, warning and preparedness indicators from its effective time without stopping the clock.
02
The rules of the model
What can and cannot change physical flow.
Warnings, observations, shelters, evacuation and communications change preparedness or exercise records. They never directly change Q.
The moving Q marker presents MHIE discharge and travel time. Its illustrated speed or curve length does not calculate hydraulics.

Actions by asset
Adapted from the attached guide, with current capability labels added for accuracy.
Modelled nowExercise actionHydraulic viewPartly modelledPlanned feature
Hydropower plant
Modelled now- Player actions
- Pre-release, turbine discharge, spillway policy, flood-buffer or energy strategy, units, dispatch, reserve and cascade coordination.
- Simulation consequence
- Recalculates storage, reservoir level, generation, release and downstream Q-ETA through MHIE. Downstream notification and dam EAP are still planned.
City / provincial capital
Modelled now- Player actions
- Issue warnings, choose communication channels, activate EAP stages, prepare evacuation, open shelters, deploy teams, protect facilities and close crossings.
- Simulation consequence
- Changes warning reach, readiness, evacuation, protected population, resources and warning lead. City actions never change river discharge.
District / village
Exercise action- Player actions
- Local warning, notification, village EAP, riverside evacuation, shelters, boats, crossing closure and requests for support.
- Simulation consequence
- The current build records these decisions in the exercise log. A resource and exposure consequence model is planned.
Monitoring station
Exercise action- Player actions
- Increase observations, request field verification, use backup telemetry and publish a station bulletin.
- Simulation consequence
- The current build records the action without changing Q. Calculated latency, confidence and maintenance effects are planned.
Tributary / catchment
Hydraulic view- Player actions
- Inspect rainfall-runoff and routed tributary Q-ETA.
- Simulation consequence
- MHIE controls physical inflow. Forecast requests, gauge intensification and tributary-watch controls are planned.
Confluence
Hydraulic view- Player actions
- Inspect mainstream and tributary flow joining on the map.
- Simulation consequence
- MHIE calculates the combined Q and mass balance. Players cannot manually change confluence discharge; coordination actions are planned.
Tonle Sap / delta area
Hydraulic view- Player actions
- Inspect routed flow and provisional downstream limitations.
- Simulation consequence
- Hydraulic exchange remains MHIE-controlled. Monitoring, navigation warning and tide/backwater scenario actions are planned.
Nam Theun 2 transfer
Partly modelled- Player actions
- Inspect the transfer system and use available plant operations.
- Simulation consequence
- The transfer paths and energy system are represented. A dedicated Xe Bang Fai receiving-risk and transfer-strategy cockpit is planned.
Construction hydropower site
Exercise action- Player actions
- Suspend works, inspect diversion works, secure equipment and evacuate the workforce.
- Simulation consequence
- These are recorded exercise decisions. They have no hydraulic gate effect unless verified temporary-work capacities are later modelled.
Planned hydropower
Exercise action- Player actions
- Compare with or without a project, review emergency access and review flood-routing assumptions.
- Simulation consequence
- Planning only. The current control records the request; a separate calculated what-if run is planned.
Regional handoff
Planned feature- Player actions
- Send a bulletin, request acknowledgement, transfer coordination lead and escalate a basin-wide response.
- Simulation consequence
- The map endpoint exists, but the operational handoff workflow is not yet available.

Quick reference
Important terms used throughout the Lab.
- Q
- Discharge in cubic metres per second (m3/s).
- Travel time
- The MHIE time assigned for routed flow to move between model nodes.
- Pulse arrival
- The remaining display time for the currently animated Q marker; it is not a new forecast.
- Threshold forecast
- Estimated time until a monitoring station reaches an alarm or flood threshold.
- Storage buffer
- Remaining synthetic reservoir storage margin available in the training model.
- EAP
- Emergency Action Plan.
- Provisional
- A training value or assumption that has not been validated for operational use.
Choose what the map emphasizes. City and hydropower project names stay fixed; critical warnings remain reachable in red clusters.
