“…An overall improvement in the condition of the stream's adjacent riparian tracts is also required (like rejuvenating the Okhla Bird Sanctuary area- Adak, 2017b ; Dixit, 2019 ; Bhatia and Vats, 2019 ), with suitable floodplain zonation and wetland regeneration, which are crucial towards maintaining river health ( Babu et al, 2013 ). The use of vegetative buffers along the river can help mitigate seasonal floods ( Mondal and Patel, 2020 ), absorb contaminants and enable better hyporheic exchanges ( Mondal and Patel, 2018 ), all factors in enhancing environmental flows and having a healthier aquatic ecosystem ( NIH, 2006 ), with the presently allocated eflow amounts being lower than what is suitable ( Soni et al, 2014 ). Urban greening and better land use management practices within the river corridor (cf.…”

The Yamuna's stretch within Delhi is considered as the dirtiest river reach in India and despite numerous restoration plans, pollution levels have risen unabated. However, the enforcement of a nationwide lockdown due to the ongoing COVID-19 pandemic can possibly provide a ray of hope. We analyze the lockdown's impact on the water quality status of this stretch using a combination of measured parameters and satellite image derived indices. Class C Water Quality Index estimates of nine stations indicate an improvement of 37% during the lockdown period. The Biological Oxygen Demand and Chemical Oxygen Demand values reduced by 42.83% and 39.25%, respectively, compared to the pre-lockdown phase, while Faecal Coliform declined by over 40%. Similar analysis of 20 major drains that meet the Yamuna revealed declining effluent loads and discernable improvements in drain contaminant status were ascertained via a hierarchical cluster analysis. Reach-wise suspended particulate matter content, turbidity and algal signatures were derived from multi-temporal Landsat-8 images of prior and ongoing lockdown periods for 117 channel segment zones. These parameters also declined notably within most stretches, although their extents were spatially varied. While the partial/non-operational status of most industries during the lockdown enabled significant reduction in effluent loads and a consequent betterment in the river water quality, its spatial variations and even deterioration in some locations resulted from the largely undiminished inflow of domestic sewage through multiple drains. This study provides an estimate of possible river recovery extents and degree of improvement if deleterious polluting activities and contaminants are regulated properly.

“…Fertilizer application needs to be ensured, following the index and chemical properties of nursery soils determined before plantation. Diammonium phosphate or organic compost such as vermicomposting and a special fertilizer "composed of cow dung, cow urine, gram flour and Trichoderma" fermented for 4 days can also be applied (Mondal and Patel 2020) (iv) Nursery Preparation: Cultivation in Golden Bags…”

The support from Project Management Unit 3 (PMU3) under the Ministry of Public Works and Transport (MPWT), Cambodia, is highly appreciated. Special thanks go to H.E Pheng Sovicheano, Secretary of State, MPWT, Cambodia for his guidance and kind support during the report development. Sardar S. Ahmed, International Material Engineer, Korea Consultants International, contributed to the study by providing necessary information regarding the Vetiver grass source and its availability in Cambodia. The cooperation and logistic support of the Department of Civil Engineering and the Directorate of Bureau of Research, Testing and Consultation, BUET, were indispensable. Samira Tasnim Progga, Research Associate, Department of Civil Engineering, BUET, provided strong contribution in the preparation of this knowledge product. Finally, the timely publication of this study was made possible by Marie France B. Balawitan's valuable coordination and administrative support.

“…This technique would be a good option, especially considering the good impacts on both environmental and socioeconomic indicators (see Tables 5 and 6). According to the hydraulic perspective, the geogrid and geocells are well-indicated to sustainably rebuild the banks (when necessary), providing steep slopes due to the preservation of the cross-section under stable conditions and the potential for erosion of the streambanks [57,107,110]. Furthermore, some authors suggested that its implementation tends to delay the peak flow rate in the watercourse, to decrease the flow energy, and to improve the rainwater infiltration process into the soil [107,108].…”

“…The techniques T6 and T3 are both (in this order) well-ranked (3rd and 4th, respectively, for Reach 1; 2nd and 3rd, respectively, for Reach 2). Thus, if we did not consider technique T2 (due to the width restriction), we could identify that the techniques T7, T6, and T3 (in this order) are the alternatives that better suit the thresholds of the local socio-economic conditions [107], being the most sustainable watercourse interventional techniques to be implemented in this case study.…”

Multi-Criteria Decision Method for Sustainable Watercourse Management in Urban Areas

et al. 2020

View full text Add to dashboard Cite

The rapid urban growth followed by disordered occupation has been generating significant impacts on cities, bringing losses of an economic and social nature that directly interfere with the well-being of the population. In this work, a proposal for local urban infrastructure problems associated with watercourse management is presented, comparing Sustainable Drainage System (SuDS) techniques and Low-Impact Development (LID) concepts with alternative traditional interventions. The study addresses sustainable alternatives to cope with the urbanization of the Cehab’s open channel, which is an important urban watercourse tributary of the Muriaé River, at the municipality of Itaperuna, Rio de Janeiro—Brazil. The multi-criteria decision-making method called Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) was applied here. The results highlighted the better performance of sustainable techniques when compared to the traditional ones, with an overall advantage of the geogrids and geocells for this case study. The obtained TOPSIS coefficients-C for these techniques were higher (0.59488, for Reach 1; and 0.68656, for Reach 2) than those for the others. This research, therefore, presented an important urban watercourse management methodology that can be further applied to guide sustainable investments and help the decision-making associated with the development of territories.
