农村土地的城市开发可能会引起对水资源和野生动物的关注。城市化可对地表水径流和地下水补给的数量和质量产生重大影响。溪流和冷水生境中的基流，例如，对于鳟鱼来说，依赖于地下水。如果含水层的水补给减少，地表径流增加，则径流和冷水生境可能受到不利影响。在明尼苏达州的Vermillion河流域的农村/自然区域的城市化导致的地下水补给的变化进行了调查。应用了渗透（土壤保护局（SCS）和Green-Ampt（GA）方法）和蒸散（联合国粮食及农业组织（FAO）-56 Penman-Monteith）估算的既定原则和关系，并使用水预算方法确定渗透或地下水补给。这些关系被组装在三个模型中，称为FAO-SCS，FAO-GA和GA模型。
Urban development of rural land can be a concern for water resources and wildlife. The quantity and quality of surface water runoff and groundwater recharge can be significantly affected by urbanization. Base flow in streams and cold-water habitat, e.g., for trout, depend on groundwater. If water recharge to aquifers is reduced, and surface runoff is increased, streamflow and cold-water habitat can be adversely affected. An investigation of the changes to groundwater recharge resulting from the urbanization of a rural/natural area in the Vermillion River watershed in Minnesota was conducted. Well established principles and relationships for the estimation of infiltration (Soil Conservation Service (SCS) and Green-Ampt (GA) methods] and evapotranspiration [Food and Agriculture Organization (FAO)-56 Penman-Monteith) were applied, and percolation or groundwater recharge was determined using a water budget approach. The relationships were assembled in three models called the FAO-SCS, the FAO-GA, and the GA mo...
