Description

Abstract. Water hyacinth (Eichhornia crassipes) is an invasive hydro plant that invaded the waters of Lake Victoria and has since been spreading rapidly affecting the socio-economic livelihood of the community around the Lake. The weed's rapid spread is due to various anthropogenic activities in the surrounding environment among them being the eutrophication of the lake waters.This study aims at using remote sensing applications and presenting the results of the analysis of the water hyacinth Normalized Difference Vegetation Index (NDVI), water extent, and analysis of correlation with the water quality over time from Sentinel 2 satellite imagery in January 2017 to January of 2021. The analysis aims at understanding the vegetation growth coverage in the five years and sets the basis of monthly predictive modelling of the behavior of water hyacinth. Predictive modelling applies historical statistical data while trying to use trend analysis in predicting the future behavior of a phenomenon. This study also seeks to answer the research question of the role of suspended sediments and dissolved minerals in abating the spread of and growth of water hyacinth.

الملخص. صفير الماء (Eichhornia crassipes) هو محطة مائية غازية غزت مياه بحيرة فيكتوريا ومنذ ذلك الحين تنتشر بسرعة مما يؤثر على سبل العيش الاجتماعية والاقتصادية للمجتمع حول البحيرة. يرجع الانتشار السريع للأعشاب الضارة إلى الأنشطة البشرية المختلفة في البيئة المحيطة ومن بينها إغناء مياه البحيرة بالمغذيات، وتهدف هذه الدراسة إلى استخدام تطبيقات الاستشعار عن بعد وعرض نتائج تحليل مؤشر الغطاء النباتي للفرق المعياري لصفير الماء (NDVI)، ونطاق المياه، وتحليل الارتباط بجودة المياه بمرور الوقت من صور الأقمار الصناعية Sentinel 2 في يناير 2017 إلى يناير 2021. يهدف التحليل إلى فهم تغطية نمو الغطاء النباتي في السنوات الخمس ويضع أساس النمذجة التنبؤية الشهرية لسلوك صفير الماء. تطبق النمذجة التنبؤية البيانات الإحصائية التاريخية أثناء محاولة استخدام تحليل الاتجاه في التنبؤ بالسلوك المستقبلي للظاهرة. كما تسعى هذه الدراسة إلى الإجابة على السؤال البحثي حول دور الرواسب العالقة والمعادن الذائبة في الحد من انتشار ونمو صفير الماء.

Les applications de modélisation prédictive des données statistiques historiques sont testées afin d'analyser la tendance à l'utilisation dans la prévision du comportement futur d'un phénomène. Cette étude examine également la question de la recherche du rôle des sédiments en suspension et des minéraux dissous dans l'élimination de la propagation et de la croissance de l'eau hyacinthe.
