What is it?
Climate (precipitation/rainfall and temperature) is a major driver for flow regimes. Rainfall is directly linked to surface water and overland flow--increases in rainfall drive higher flows. The relationship between temperature and flow is more complicated but generally higher temperatures lead to higher evapotranspiration rates which reduce flow. This situation is different when snow pack is melting, as higher temperatures increase meltwater and can increase flow.How to use it:
To apply rainfall for overland flow in the current the model zone:1) Check box next to "Rainfall"
2) Select input format "Constant", "Transient", or "From Rain Gauges". Note that "Constant" units are length/day.
3) Input data with selected method.
To apply temperatures for overland flow in the current the model zone:
1) Check box next to "Temperature"
2) For both Maximum and minimum temperature
a) Select input format "Constant", "Transient", or "From Rain Gauges".
b) Input data with selected method.
