The change in the amount of erosion, sedimentation and permeability is directly related to the change in the physical and chemical properties of soil, especially for marl formation (MF). Any hydrological modeling should be verified with land use (LU) and surface parameters of MF. For this purpose, soil hydrological response (HR) and soil loss were estimated for different LU units in Iran’s Sorkhab MF using ArcSWAT model. The output of the model was compared with the real data obtained from Kamphorst rainfall simulator (RS). The results showed that modeling well separated the changes through HR in different LUs of MF. Moreover, there was no statistically significant difference (R² = 0.72 and E_NS = 0.68) between results of RS and SWAT modeling (p < 0.05). The estimated sediment and the runoff rate were 4.62 t ha⁻¹ and 6.54 m³ ha⁻¹, respectively, for the large simulated unchanged units, and the amounts of sediment and runoff were 87.8 t ha⁻¹ and 8.28 m³ ha⁻¹, respectively, for units under land-use change (LUC). Generally, SWAT model has the ability to show the soil HR under LUCs in MFs.

SWAT模型确定泥灰岩水文响应的效率

侵蚀，沉积和渗透率的变化与土壤的物理和化学特性的变化直接相关，尤其是对于泥灰岩形成（MF）。任何水文模型都应通过土地利用（LU）和MF的地表参数进行验证。为此，使用ArcSWAT模型估算了伊朗Sorkhab MF中不同LU单元的土壤水文响应（HR）和土壤流失。将模型的输出与从Kamphorst降雨模拟器（RS）获得的真实数据进行比较。结果表明，通过MF，不同建模单元的HR可以很好地分离变化。此外， RS和SWAT建模结果之间无统​​计学差异（R ²  = 0.72和E _NS = 0.68）（p <0.05）。对于较大的模拟不变单位，估算的泥沙和径流量分别为4.62 t ha ^-1和6.54 m ³  ha ^-1，而泥沙和径流量分别为87.8 t ha ^-1和8.28 m ³  ha ^-1分别针对土地利用变化（LUC）下的单位。通常，SWAT模型具有显示MFs中LUCs下土壤HR的能力。
