Components of water budget for lawn-planting are considered to be the amount of precipitation, drain-off, water storage, evaportranspiration and condensation. We made two types mock-up for measure of the above items. Measured datas were analyzed from the following view points. 1. Diurnal and annual change of each components of water budget. 2. Relationships between precipitation and draining from lawn-planting befor and after at rain fall. 3. Relationships between weather parameters and evaportranspiration or condensation.
