Dongbian River — Water Environment Restoration & O&M

2019
Water · Governance

Water environment restoration and long-term operations & maintenance for the Dongbian River (Dongbian Yong), Guangdong — organized under the EAVC standard using the PAD methodology and CMM specialist coordination. Financial deviation from derived cost calculation: 0.77%. Confirmed stable water environment conditions in 2023 and 2025 follow-up reports.

The Demand

The Demand

The Dongbian River required comprehensive water environment restoration and a long-term operations and maintenance system. Key measurement parameters identified through PAD sensing:

Foundation Layer (earth/soil):

- NTU (Nephelometric Turbidity Units)

- ORP (Oxidation-Reduction Potential)

Flow Layer (liquid):

- COD (Chemical Oxygen Demand)

- NTU (Nephelometric Turbidity Units)

- ORP (Oxidation-Reduction Potential)

- DO (Dissolved Oxygen)

Power Layer (energia ordinata):

- Phosphorus (P)

- Nitrogen (N)

Power Layer (chaos/entropia):

- Phosphorus (P)

- Nitrogen (N)

How IESASP Organized the Solution

How IESASP Organized the Solution

① (P) Primal Perception: UAV (Unmanned Aerial Vehicle) remote sensing and GIS-based sensing

② (A) Analogy: Established a spatiotemporal knowledge base and spatiotemporal information database associated with Dongbian Yong, integrating with EAVC (Energy Anchored Value Consensus)

③ (D) Derivative: Water (and sediment) environmental remediation framework based on value consensus

④ Integration based on D — Mosaic specialist team:

a) Algae specialists

b) Chemistry specialists

c) Business management professionals

d) Radio/wireless communication specialists

e) Certified testing laboratories (with statutory qualifications)

f) Manufacturing team

⑤ Mosaic horizontal division of labour — deliverables:

a) Solution design: Dongbian River proposals, meeting records, and field investigation records (2019 – February 2020)

b) Prototype formulation testing: work reports

c) Equipment and facility design: design blueprints

d) Engineering implementation design: construction blueprints

e) Derived cost calculation: Dongbian River budget

f) Composition testing: test reports

g) Project acceptance: acceptance reports (3 rounds)

h) Work implementation: work orders and payment vouchers

Sediment value conversion (Power Layer):

- Extracted eutrophic sediment from Dongbian River

- Combined with a defined proportion of natural materials

- Manufactured into porous, breathable chelated bricks to preserve the anaerobic layer of the riverbed

- Includes brick design drawings, material formulations, installation guidelines, and testing

Long-term Operations & Maintenance

Long-term Operations & Maintenance

① (P) Primal Perception: Digital dock uploads 31 sensing parameters at a frequency of six times per minute

② (A) Analogy: Provides dynamic anomaly values based on EAVC (Energy Anchored Value Consensus)

③ (D) Derivative — O&M System:

a) Anomaly-triggered alerts and maintenance work orders

b) Unattended articulated-module operations and maintenance

c) Emergency entropy reduction handling of disordered energy

d) Mosaic-style division of labour: operations personnel respond to task allocations generated by the D-derivative system

Emergency Response Case — March 2021:

a) Nutrient concentration instantly exceeded threshold; anomaly values triggered system alarms with imaging showing large-scale discharge input from fishery sources

b) Unattended articulated modules initiated emergency operations; all systems engaged

c) Operations personnel arrived on-site within 1 hour to conduct nutrient dilution treatment

d) Water environment of Dongbian River restored within 24 hours
