Twin figures for the Tonle Sap and the Lower Mekong at Phnom Penh, counted from its layers at their stated dates.

Twin builder and simulator.

For Nexus-Based Risk Management (NRM): the faculty's twin of Tonle Sap on the planet map, the globe and in 3D. Pick a generator, switch layers, run the instruments; every layer prints its provider and date.

The Tonle Sap and the Lower Mekong at Phnom Penh: a flat plan of the faculty twin. Terrain 0 to 1,700 m; River 2,956 km; 14 dams; 6 power plants, 88 MW; Tree cover 37.8 percent of the box; Cropland 39.9 percent of the box; Built-up 0.9 percent of the box; Permanent water 4.7 percent of the box; River discharge, GloFAS via Open-Meteo: live, loads in the twin; Vegetation index, MODIS Terra NDVI 8-day: live, loads in the twin; Surface water extent, OPERA DSWx (HLS): the flood pulse: live, loads in the twin; Land cover classes, MODIS IGBP (annual): live, loads in the twin. Contours every 250 metres from the elevation grid; named rivers by class; cropland, tree cover, water and built-up shares (esa worldcover 2021) as the class holding a quarter or more of each cell; dams as marks; power plants as marks.

The discipline in brief.

It does not replace enterprise risk management: entity-level practice under ISO 31000 and COSO, the discipline tracks and disaster risk reduction under the Sendai Framework each keep their own scope, and NRM nests them on a scope ladder from entity to sector, system of systems, region and planet and governs the interdependencies, cascades, compound events and shared exposures between them. The discipline teaches the eight-step method cycle: scope the nexus system, map interdependencies as a typed and sourced graph, build compound and cascade scenarios, stress test the system, appraise a portfolio of options across levels, design anticipatory triggers and finance, govern shared exposure and hand off to the actor with authority, and monitor, learn and correct; the upward flow of register dependency fields into the nexus layer and the downward flow of systemic notices, tolerances and scenario packs; evidence grades from not bound to validated, kept separate from any single score; and NRM profiles as the form a nexus system is written in. The faculty's twin is its first case: the Tonle Sap loop and the cascade matrix are steps two to four of the cycle on real data, with every coupling labelled as a teaching sensitivity. A graduate can place an entity register on the ladder, run the cycle on a basin and write the systemic notice that goes back down, graded by its evidence.
