Various types of equipment are often made within the Department to specific requirements and particularly when a permanent installation is required. Site surveys - Field sites can be thoroughly and accurately surveyed. Communication during this phase is important, particularly on safety grounds. Two total station Geodimeters with partial computer interface capability are available. There is also a wide range of standard levels accompanied by levelling staffs and ranging poles.
Surveying chains are also available for traditional methods.
Soil and Sediment sampling - Samples of soil may be taken to determine the soil type and structure. A comprehensive range of sampling equipment is available including a petrol-driven drilling rig. The entire boring system is in the process of rationalisation so that a standard bayonet locking sleeve is used in each case. Soils and sediments are analysed in the Physical Geography Laboratories . Instrumentation of field sites - Deployment of measuring sensors can range from the simple task of inserting erosion pins into the ground and making regular height measurements, to using expert divers for the placement of pressure transmitters on the bed of estuaries.
