Performance Evidence

The candidate must be assessed on their ability to integrate and apply the performance requirements of this unit in a workplace setting. Performance must be demonstrated consistently over time and in a suitable range of contexts.

The candidate must provide evidence that they can:

access and collate existing hydrological information

collect and analyse hydrological data using appropriate sustainable practices

collect and assess a wide range of hydrological data

determine the movement of water within a catchment from existing data

assess processes within catchment to evaluate non-sustainable practices in catchments

report on catchment hydrological behaviour to organisational requirements

apply work health and safety practices to the collection and testing of water

apply an awareness of biosecurity in the context of own work

---

Knowledge Evidence

The candidate must demonstrate knowledge of factors used for analysis of water catchment area:

hydrological cycles

chemical and physical properties of water

rock and soil types including weathering processes

fluvial geomorphology:

drainage basin function

factors influencing stream flow rates

interactions between ground and surface water

stream hierarchy and ordering

human impacts on surface water quality and quantity

hydrogeology:
