#### 4.7.3 Use Case 3: Financial Audit for Municipal Water Resources Management Scenario  
A financial audit is initiated in a municipality to ensure the proper allocation and use of funds for water resource projects, such as improving water supply systems, maintaining drainage infrastructure, and disaster preparedness for water-related issues (e.g., flooding, droughts). This financial audit ensures that municipal funds for water management are used efficiently and transparently, preventing future mismanagement and improving the municipality's ability to respond to water-related challenges [29].  
1. **Request submission**: the MayorAgent submits a formal request to the SecretariatAgent to initiate a financial audit of the municipality's water management expenses [30].
2. **Verification process**: The **SecretariatAgent** assesses the audit's scope and necessity by reviewing financial records, past audits, and any reported complaints or irregularities from the **CitizenAgent** or municipal staff [31]. Simultaneously, the **TreasuryAgent** compiles detailed financial records, including budget allocations, contract payments, and receipts for water-related projects, ensuring transparency and accountability in municipal financial management [32].
3. **Safety checks**: The TreasuryAgent conducts internal safety checks to identify any major anomalies in the financial data before the audit begins. This process involves verifying the completeness of invoices, detecting duplicated payments, and ensuring that all financial transactions comply with municipal regulations related to procurement and project execution. These checks help maintain financial integrity and regulatory adherence [33]. The **MayorAgent** ensures that an external audit firm or independent financial experts are involved to maintain transparency and fairness [34].
4. **Resolution drafting**: The SecretariatAgent, in collaboration with the TreasuryAgent, drafts an audit report outlining key findings, including misallocation of funds for water projects, overpayment to contractors, incomplete infrastructure work, and inefficient spending on disaster preparedness, such as unused water pumps or understock emergency supplies. The report includes recommendations for improvement, such as revising procurement policies, strengthening oversight mechanisms, and reallocating funds to critical projects. The MayorAgent reviews the audit report and proposes corrective actions to address the identified issues.
* **Permit issuance**: The MayorAgent authorizes permits for new financial controls and budget reallocations to address the issues identified in the audit. The TreasuryAgent ensures that all approved financial adjustments comply with municipal regulations. To maintain transparency and public trust, the CitizenAgent communicates the audit findings through public channels. This financial audit guarantees the efficient and transparent use of municipal funds allocated to water management, helping to prevent mismanagement and enhancing the municipality's capacity to address water-related challenges effectively.
