This describes the essential skills and knowledge and their level, required for this unit.

Required skills:

use mathematical techniques to analyse and model flood data

prepare and plan strategically

computer skills

collect and interpret data

model data

develop clear and effective reports

communicate effectively

interpret data

manipulate data

communicate with a range of stakeholders

Required knowledge:

catchment hydrology principles

water flow measurement; flow routing

relevant legislation, by-laws and planning schemes

mathematical calculation

cultural environment

occupational health and safety and environmental legislation, Acts and procedures

The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for the Training Package.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

The candidate should demonstrate the ability to analyse and develop flood mitigation warning systems and strategies using the effective:

collecting relevant data

analysing relevant data

modelling data

developing critical flood warning systems

developing strategies to mitigate the impact of potential future floods

preparing clear, concise and timely reports

communicating data and outcomes to stakeholders and team members

Context of and specific resources for assessment

Access to the workplace and resources including:

documentation that should normally be available in a water industry organisation

relevant codes, standards, and government regulations

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 requires that:

competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace

where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice

a decision of competence should only be made when the assessor has complete confidence in the person's competence over time and in various contexts

all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence

where assessment is for the purpose of recognition (RCC/RPL), the evidence provided will need to be authenticated and show that it represents competency demonstrated over a period of time

assessment can be through simulated project-based activity and must include evidence relating to each of the elements in this unit

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.

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance.
