	* The seepage fluctuation parameter starts at a negative value. It increases (but remains negative) after 2 days. 2 days later it becomes high and positive, and during the last 2 days the value is 0. This means the amount of seepage due to fluctuation changes every 2 days.		* The seepage fluctuation parameter starts at a negative value.

	* The simulation lasts for 8 days. During these eight days only the water level, ground water level and the seepage influence the outcome, disruptive factors such as rain or evaporation have no influence in this case.		* The simulation lasts for 8 days.

	## The "Groundwater (Spatial)" Overlay calculates and shows the result for the seepage calculation, with a static amount of pressure and resistance affecting the groundwater levels, without any configured fluctuation.		## The "Groundwater (Spatial)" Overlay calculates and shows the result for the seepage calculation, with a static amount of pressure and resistance affecting the groundwater levels, without any configured fluctuation.
	## The "Groundwater (Fluctiation)" Overlay calculates and shows the results for a seepage calculation, in which natural pressure and resistance are configured to limit base seepage, so that the effect of seepage fluctuation is more visibly demonstrated.		## The "Groundwater (Fluctiation)" Overlay calculates and shows the results for a seepage calculation, in which natural pressure and resistance are configured to limit base seepage, so that the effect of seepage fluctuation is more visibly demonstrated.
