Elements and Performance Criteria
ELEMENT |
PERFORMANCE CRITERIA |
1 Plan and assess survey requirements . |
1.1 Planned survey exercises directly relate to the desired outcome and required standard processes and software . 1.2 Identify the location and value of survey reference marks from maps and plans. 1.3 Choose and justify appropriate survey techniques for specific hydraulic conditions and hydrographic purposes. 1.4 Identify and evaluate the source of levelling errors and misclosures. 1.5 Plan and manage the logistics and personnel to ensure effective outcomes and resource management. 1.6 Apply correct care procedure for storage, transport and use of survey equipment. 1.7 Assess and address occupational health and safety issues that may be encountered during the surveying exercise taking appropriate risk management strategies. 1.8 Apply for and confirm appropriate authorisations for entry to property for the purpose of carrying out survey exercise. |
2 Operate survey equipment . |
2.1 Set up survey equipment and use mathematical techniques to check for correct operation and prepared for use. 2.2 Carry out collimation test to check the level for accuracy. 2.3 Select survey equipment for suitability and use correctly and safely according to operating procedures. |
3 Select and survey monitoring sites . |
3.1 Identify required survey reference marks (bench marks). 3.2 Establish cease-to-flow level of controlling feature. 3.3 Identify and assess high-flow cross section and sectional control by survey. 3.4 Survey multiple cross sections of channels to determine the profile of the channel in the gauging station reach. 3.5 Identify and assess groundwater monitoring site survey reference points |
4 Document survey and data results . |
4.1 Correctly and accurately document and store results and verify in corporate database according to organisation and industry standards. |

Critical aspects for assessment and evidence required to demonstrate competency in this unit |
The candidate should demonstrate the ability to use appropriate survey equipment to collect survey data at monitoring stations and to process and manage the data for hydrometric purposes including:
|
Context of and specific resources for assessment |
Access to the workplace and resources including:
Where applicable, physical resources should include equipment modified for people with disabilities. Access must be provided to appropriate learning and/or assessment support when required. Assessment processes and techniques must be culturally appropriate, and appropriate to the language and literacy capacity of the candidate and the work being performed. Validity and sufficiency of evidence require that:
In all cases where practical assessment is used it will be combined with targeted questioning to assess the underpinning knowledge. Questioning will be undertaken in a manner appropriate to the skill levels of the operator, any cultural issues that may affect responses to the questions, and reflecting the requirements of the competency and the work being performed. |
Range Statement
