|LabCOIntro=In this lab, we are using a theoretical river basin of ~1990 km<sup>2</sup>, with 1200m of relief and a river length of ~100 km. All parameters that are shown by default once the HydroTrend model is loaded are based on a present-day, temperate climate.

Whereas these runs are not meant to be specific, we are using parameters that are realistic for the Waiapaoa River in New Zealand. The Waiapaoa River, located on North Island, receives high rain and has erodible soils, so the river sediment loads are exceptionally high. It has been called the 'dirtiest small river in the world'. A more detailed description of applying HydroTrend to the Waipaoa basin has been published in ''Water Resources Research'': http://dx.doi.org/10.1029/2006WR005570.

Introduction
In this lab, we use the HydroTrend model to investigate river sediment supply to the ocean by exploring the effects of climate change on river fluxes. We also look at the effect of humans on rivers: the building of a reservoir.
Classroom organization In this lab, we are using a theoretical river basin of ~1990 km2, with 1200m of relief and a river length of ~100 km. All parameters that are shown by default once the HydroTrend model is loaded are based on a present-day, temperate climate.
Whereas these runs are not meant to be specific, we are using parameters that are realistic for the Waiapaoa River in New Zealand. The Waiapaoa River, located on North Island, receives high rain and has erodible soils, so the river sediment loads are exceptionally high. It has been called the 'dirtiest small river in the world'. A more detailed description of applying HydroTrend to the Waipaoa basin has been published in Water Resources Research: http://dx.doi.org/10.1029/2006WR005570.
