“…This multispectral imageries helps to identify the changes periodically happened in water hyacinths. Al-lami et al [3] proposed vegetation indices for monitoring the spread of Nile Rose plant in the Tigris River within Waste province, Iraq using water hyacinths on the surface of water. Once they removed all wastages vegetable cultivations are experimented with the purified water.…”

“…Water hyacinth scientifically called Eichhornia crassipes is generally grown in South America's subtropical and it's native too. Generally, the growth of the water hyacinth is a minimum of 40cm and a maximum of 1m in the water-filled areas [1][2][3]. The industrial effluent particles are connected with the water places such as lakes, ponds, rivers, and pits.…”

INTRODUCTION: Industries and factories are the backbone of any nation to increase the economy through its productivity and develop the county globally. But the wastages and sewages produced by each industry are creating pollution and make cleanliness environment on the society. OBJECTIVES: The recycling process and decontamination process of that industrial effluent is a challenging task for all the industries in and around the world. Ancient techniques are followed in industrial effluent cleaning processes but the output of those is not sufficient in terms of recycling.. METHODS: Phytoremediation is the new technique used to control industrial effluent with the help of water hyacinth available in the water places. This paper discussed all possible solutions of industrial effluent removal along with water quality improvement techniques. Decontamination of the industrial effluent using water hyacinth is mainly dealt in leaves, stems, and root parts. There are only water hyacinth is used to remove industrial effluent, no other products like powder, liquid plants, and other chemicals are used. RESULTS: Total duration of 21 days has to be considered for the growth of water hyacinth used in water places to monitor the recycling of industrial effluent at different parts. A water quality test has been conducted to identify the level of contaminants in the Industrial effluent. Furthermore, BOD (Biological oxygen demand), COD (Chemical oxygen demand), TDS (Total dissolved solids), TSS (Total suspended solids), Turbidity, and chloride levels are taken as a parameter from the industrial effluents. CONCLUSION: Every 24hours, for continuous 3-5days the color of effluent has been notified to predict the changes. Turbidity and other impurities are noted by the effects of the water hyacinth used as results.

“…Spectral signatures are popularly used in identifying different objects, landforms, vegetation including various species etc. 11 In mapping the presence of WH we make use of individual bands from the multi-spectral drone imagery to form WH spectral signature. Details of the five different bands are given in Table 1.…”

Pontederia crassipes, commonly known as water hyacinth (WH), is a highly invasive aquatic weed and its infestation has caused significant adverse ecological and economic impact across the world. Remedial actions include manual monitoring and removal which are often time consuming and expensive. This paper proposes the use of multi-temporal multi-spectral drone imagery for WH mapping and monitoring in Patancheru Lake, located in the outskirts of the Indian city Hyderabad. The data collection was done in two steps: 1) multi-spectral drone based data acquisition by aerial survey and 2) ground level optical image capturing through an Android mobile application named MPRO. Data was collected in regular interval starting from January 2021. Spectral bands were used to produce the WH detection and mapping. We compare spectral signature of clean and infested water for five different sites inside the lake. Multitemporal water quality samples of these sites were also collected together with drone data to analyse the effect of WH infestation on those parameters. The multi-spectral data was processed using an unsupervised machine learning classifier named expectation maximisation (EM) clustering to create a segmentation map indicating WH, water and other regions.

“…Cl red edge and MSR have been related to chlorophyll concentration (Cl red edge [24]) and Fraction of Absorbed Photosynthetically Active Radiation -FAPAR (MSR [25]), both of which exert an influence in the primary productivity of ecosystems. DVI, on the other hand, is more closely related to biomass and LAI [26], thus being more (less) sensitive to the vegetation cover (physiological status). Hence, among the 16 indices analyzed, the combined analysis of Cl red edge, MSR and DVI is considered a good option for the timely detection of P. crassipes in the IHP reservoir.…”

Pontederia crassipes Pellegrini & Horn (water hyacinth) is an invasive, world-wide distributed aquatic plant, which has been evinced in the reservoir of the Ituango Hydroelectric Project - IHP (Colombia) since 2018. In this study, the ability of several Vegetation Indices (VIs) to detect P. crassipes was evaluated based on monthly Sentinel-2 images, between September 2018 and March 2020. The invasive capacity of P. crassipes was demonstrated with covered area doubling each month in the IHP reservoir. A maximum 32-fold increase of P. crassipes in just one month was registered during the rainy season and resulted in a 104-ha expansion. Results based on Cl red edge, MSR, and DVI were consistent and had less deviations from normality. Our results highlight the importance of new-generation sensors to discriminate and map the spatial distribution of P. crassipes for the development of efficient monitoring and management strategies at the reservoir scale.
