Inland excess water (IEW) is a form of surplus surface water, often regarded as a specific flood type. However, it occurs most frequently in local depressions of large flat areas, irrespective of river floods and the surface water networks. IEW is considered to be a typical Carpathian Basin problem, as it can cause major land degradation problems in the agricultural areas of Hungary, mainly located on the Great Hungarian Plain (GHP). An innovative method for mapping the probability of IEW inundation is proposed in this study. This method is based on the geostatistical modelling of the relationship between the natural and human driving factors and the occurrence of IEW inundations. The results show that significant part of the GHP (about 500,000 hectares) is moderately or highly affected by IEW inundations, where the combination of multiple influencing factors simultaneously occur. The resulted IEW inundation probability map can be used to meet future challenges in agricultural management and the adaptations to climate change effects.

匈牙利大平原内陆过量水危害的综合空间评估

内陆过剩水（IEW）是一种多余的地表水，通常被视为特定的洪水类型。但是，无论河流洪水和地表水网络如何，它最常发生在大平坦地区的局部洼地。IEW被认为是典型的喀尔巴阡盆地问题，因为它可能导致匈牙利主要位于匈牙利大平原（GHP）的农业地区出现严重的土地退化问题。在这项研究中提出了一种新颖的方法来绘制IEW淹没的可能性。该方法基于自然和人为驱动因素与IEW淹没发生之间关系的地统计学模型。结果表明，全球水电计划的很大一部分（约500,000公顷）受到IEW淹没的中度或高度影响，多个影响因素同时发生的地方。所得的IEW淹没概率图可用于应对农业管理和适应气候变化影响方面的未来挑战。
