Floods have an important impact on life and loss of goods. Urban green spaces are crucial to mitigating flood impact. However, their capacity to prevent floods depends on their condition, especially in areas highly affected by human activities such as lawns. Here, we developed a simple method to assess flood regulation using soil penetration resistance as a proxy and tested it on an urban lawn in Vilnius (Lithuania) in winter. We developed an experimental design using an app for collecting data and working with it in a GIS environment. To understand their spatial relations, geostatistical (e.g., semi-variogram model and ordinary kriging mapping) and spatial statistics ((Moran's global autocorrelation index and Cluster and Outlier Analysis (Anselin Local Moran's I)) tools were applied. The preliminary results from the tested method showed that the lawn studied has different capacities to retain floods due to the management practices. Nevertheless, it is essential to be applied in different soil moisture conditions since flood regulation (soil penetration resistance) can be variable throughout the year.•A novel method was developed to estimate flood regulation using soil penetration resistance as a proxy;•An urban lawn was used to test the method and identify areas with low and high capacity for flood regulation;•The method quickly assesses lawn flood retention capacity in different environments.
洪水对生命和财产损失有着重要影响。城市绿地对于减轻洪水影响至关重要。然而，它们的防洪能力取决于其状况，尤其是在受人类活动影响较大的区域，如草坪。在此，我们开发了一种简单的方法，以土壤穿透阻力为替代指标来评估洪水调节能力，并在冬季对立陶宛维尔纽斯的一块城市草坪进行了测试。我们利用一款应用程序开发了一个实验设计，用于收集数据并在地理信息系统（GIS）环境中进行处理。为了解它们的空间关系，应用了地质统计学工具（如半变异函数模型和普通克里金法绘图）以及空间统计学工具（莫兰全局自相关指数和聚类与离群值分析（安塞林局部莫兰指数I））。测试方法的初步结果表明，由于管理措施的不同，所研究的草坪具有不同的洪水滞留能力。然而，由于全年洪水调节能力（土壤穿透阻力）可能会有所变化，因此该方法必须在不同的土壤湿度条件下应用。
•开发了一种以土壤穿透阻力为替代指标来估算洪水调节能力的新方法；
•利用一块城市草坪对该方法进行测试，并确定洪水调节能力低和高的区域；
•该方法能快速评估不同环境下草坪的洪水滞留能力。
