1.1 The main hydrological characteristics and processes which operate in rivers and drainage basins
1.1.1 Characteristics of rivers and drainage basins: the long profile, width, depth, speed of flow/velocity, discharge, wetted perimeter, channel, watershed, tributary, confluence, source, mouth.
1.1.2 The Bradshaw model.
1.1.3 How the drainage basin operates within the water cycle.
1.1.4 Processes which operate in a drainage basin: precipitation, interception, infiltration, percolation, overland flow, channel flow, throughflow, groundwater flow, transpiration, evaporation, evapotranspiration.
1.1.5 Processes which operate within a river: • erosion; hydraulic action, abrasion, attrition, solution • transportation; traction, suspension, saltation, solution • deposition.
