SahysMod is a computer program for the prediction of the salinity of soil moisture, groundwater and drainage water, the depth of the watertable, and the drain discharge in irrigated agricultural lands, using different hydrogeologic and aquifer conditions, varying water management options, including ...
An integrated spatial-agro-hydro-salinity model (SahysMod) was used to model field soil and groundwater salinity dynamics in coastal rainfed farmland, and calibration, error analysis, and sensitivity analysis were performed for the SahysMod model. Results indicated that a leaching efficiency ranging...
该研究以银北灌区典型区域-西大滩为例,综合考虑荒地与耕地土壤属性的空间变异性,以2015—2016年土壤盐分数据进行率定,2017年盐分数据作为验证,利用SahysMod探索在土地整治过程中不同灌排管理下未来10 a内土壤水盐动态变化。结果表明,现有灌排管理下(即灌水量为670 mm,灌溉水电导率为1.05 dS/m,排水沟深1.5 m),荒...
【方法】以河套灌区为研究对象,综合考虑气象,水文地质,土壤,灌溉,作物等多因素的空间变异 性,结合 SahysMod 分布式模型与 GIS 软件,基于 2007—2012 年和 2013—2016 年的实测数据对模型进行率定及验 证,模拟不同情景方案下的水盐动态变化.【结果】在现有灌排条件下,年排水量呈先减小后逐渐稳定的趋势,年 排水...
The results showed that SahysMod could be used as an effective tool to simulate regional water and salt balances under different irrigation and drainage managements considering the spatial variability of soil properties. Irrigation amount, electrical conductivity of irrigation...
