Saïss plain contains an important aquifer. This complex groundwater system plays an important socio-economic role. Managing the groundwater resources requests a good understanding of resources availability and human needs satisfaction. These two components are estimated to get annual water balance of Saïss aquifer. Resources availability depends on meteorological parameters (rainfall, wind speed, temperature, etc.), soil types, topography, water table, and land use. Previous studies do not consider all of these parameters in assessing the water resources availability in this region. In this study, we have identified the relationship between all Saïss hydro-meteorological parameters and we have organized all data in Geographic Information System (GIS) to assess inputs of the water balance. Meteorological and hydrological data and landuse/landcover maps obtained from Landsat imageries classification were used in Wet-Spass (water and energy transfer between soil, plants, and atmosphere under quasi-steady state) model and Soil Conservation Service Curve Number (CN-SCS) method to assess annual runoff, potential evapotranspiration, interception, actual evapotranspiration, and natural recharge of shallow aquifer of Saïss plain. The results of the water balance calculation indicate significant fluctuations in the aquifer recharge: 280 Mm³ (1987) and 418 Mm³ (2018). The annual direct runoff increased from 344 Mm³ (1987) to 638 Mm³ (2018).

使用遥感，湿绕模型，CN-SCS和GIS进行水平衡评估，以进行SaïssPlain（摩洛哥）的水资源管理

塞斯平原上有重要的含水层。这个复杂的地下水系统起着重要的社会经济作用。管理地下水资源要求对资源可用性和人类需求满意度有充分的了解。估计这两个组成部分将获得Saïss含水层的年度水平衡。资源的可用性取决于气象参数（降雨，风速，温度等），土壤类型，地形，地下水位和土地利用。先前的研究在评估该地区的水资源可用性时并未考虑所有这些参数。在这项研究中，我们已经确定了Saïss所有水文气象参数之间的关系，并且已组织了地理信息系统（GIS）中的所有数据来评估水平衡的输入。从Landsat影像分类获得的气象和水文数据以及土地利用/土地覆盖图用于湿绕过（准稳态下土壤，植物和大气之间的水和能量传递）模型和土壤保护服务曲线编号（CN-SCS）一种评估塞伊斯平原浅层含水层年径流量，潜在蒸散量，截留量，实际蒸散量和自然补给量的方法。水平衡计算的结果表明，含水层补给量有较大波动：280 Mm 塞斯平原浅层含水层的实际蒸散量和自然补给。水平衡计算的结果表明，含水层补给量有明显的波动：280 Mm 塞斯平原浅层含水层的实际蒸散量和自然补给。水平衡计算的结果表明，含水层补给量有较大波动：280 Mm³（1987）和418 Mm ³（2018）。年直接径流量从344 Mm ³（1987）增加到638 Mm ³（2018）。
