    An anti flood screen on inner slope may be an important part of earthwork dike. Groundwater level fall, decrease of groundwater flow through aquifer and local increase of water velocity around screen are additional results of screen work. Such screen will effectively decrease water flow when its thickness and permeability is optimal to specific cross section. In the paper an influence of screen parameters on seepage conditions is investigated using a mathematical model. A linear relationship between flow characteristic and screen parameters was confirmed. The necessary conditions for effective work of earth screen is its workmanship according to projected parameters.
