摘要

研究区域摩洛哥东北部angads平原研究重点本研究旨在通过引入一种新的定制灌溉水质指数（CIWQI）来评估用于灌溉目的的地下水质量，通过使用因子分析适应当地的水化学特性来提高精度。研究结果表明，受自然和人为因素的影响，研究区地下水质量具有高度的变异性。一些井含有优质的水，适合没有重大限制的灌溉，而另一些井含有高浓度的溶解盐，限制了它们的农业用途。常规指标（SAR、Na%、KR和MH）不存在季节变化，但CIWQI指数表明，湿润期水质较好（53.3% %的样品属于中等至良好），而干燥期水质较好（22.2% %的样品属于中等质量）。这个指数更好地适应了当地的特点，更准确地反映了季节变化。这项研究强调，使用适应当地环境的指数能够更准确地评估水质。

Assessment of groundwater quality for irrigation using a new customized irrigation water quality index

Study region

Angads plain, Northeastern Morocco

Study focus

This study aims to assess groundwater quality for irrigation purposes by introducing a new customized irrigation water quality index (CIWQI) to improve precision by adapting to local hydrochemical specificities using factorial analysis.

New hydrological insights for the region

The results reveal a high degree of variability in groundwater quality in the study area, influenced by both natural and anthropogenic factors. Some wells contain good quality water, suitable for irrigation without major restrictions, while others have high concentrations of dissolved salts, limiting their agricultural use. Conventional indices (SAR, Na%, KR and MH) did not show seasonal variations, but the CIWQI index showed that water quality is better during the wet period (53.3 % of samples classified as moderate to good quality) compared to the dry period (22.2 % moderate quality). This index, better adapted to local specificities, more accurately reflects seasonal variations. The study underlines that the use of indices adapted to the local environment enables a more accurate assessment of water quality.
