摘要
Small weirs may control the groundwater level of drained fields in such a way that a balance between concerns of agriculture, flood prevention and water quality may be achieved. Based on a spreadsheet calculation, an easy to use software package is presented considering the interactions between precipitation, groundwater level, drain discharge, ditch runoff and weir action. Examples of calculation performed show the potential of flood prevention in different soils, the effect of different drain spacing and the influence of ditch maintenance on the operation of the entire system.
