Hydrodynamic and Advection-Dispersion Simulation of Cool Seawater Discharges from an LNG Facility(Indian Journal of Geo-Marine Sciences)
(Ankit Gupta, Ritesh Vijay, Rakesh Kumar,49,,7-14,Year : 2015)
|
The impact of cool seawater discharge in the coastal waters from a Liquefied Natural Gas (LNG) plant has been simulated using MIKE21. In this work, hydrodynamics conditions of the coastal waters were calibrated and corroborated to predict the cool seawater discharge under two plant design scenarios by selecting flow rate 15 m3 /s and 10 m3 /s with a temperature drop of 5 °C and 7 °C, respectively. The simulations were carried out under different scenarios, to arrive at the best possible case to minimize the potential impact on the coastal environment. Both the simulated scenarios complied with the available World Bank guidelines for LNG facilities. However, the designed scenario of flow rate 10 m3 /s with a temperature drop of 7 °C between inlet and outlet presents a better choice as it reduces the pumping power of seawater intake. As there are no Indian guidelines for cool seawater discharges from LNG plant, the present work can support the policymakers and regulators to formulate coherent discharge standards.

GIS based DRASTIC approach for groundwater vulnerability in Puri city, India(Journal of Environmental Science and Engineering)
(Ritesh Vijay, S. S. Ramya and P. K. Mohapatra Journal ,,,,Year : 2015)
|
Groundwater pollution is mainly caused due to the domestic and industrial activities which pollute the shallow aquifers. Puri city is such an important and pilgrim place where groundwater is getting contaminated by various anthropogenic activities. The vulnerability assessment of groundwater is mainly carried out to define the areas critical for the groundwater contamination. For this, GIS based DRASTIC model was used to assess the groundwater vulnerability considering groundwater level, hydro-geological parameters, land use pattern and topographic condition. It was found that most of the city area is highly vulnerable to groundwater contamination due to sandy aquifer property. The output of DRASTIC model helps in suggesting measures for protecting the groundwater from further contamination and management.

(Ritesh Vijay, Puja Khobragade, R. A. Sohony, Rakesh Kumar and S. R. Wate ,43,,10,Year : 2014)
|
To assess the impact of sewage discharges on creek water quality, a hydrodynamic and water quality simulation was carried out for Thane Creek. DO and BOD values showed non-compliance up to middle and upper stretches during low tide and even in upper stretch during high tide. FC was found beyond compliance level during low and high tides. Simulated results were correlated with observed tide and current as hydrodynamics and DO, BOD and FC as water quality parameters with correlation coefficients 0.66 to 0.91.

Trip Time Comparison of Conventional and Exchange Container Mode for Solid Waste Bins Collection: A Case Study of Ilorin Nigeria(Journal of Environmental Science and Engineering)
(A.S. Aremu, Ritesh Vijay O.O. Adeleke,55,1,1-8,Year : 2013)
|
The use of hauled container system for municipal solid waste collection and transportation often results in socio-economic and environmental impacts which are linearly related to trip time. In this study, trip times for the conventional and exchange container mode of solid waste collection by the hauled container system were evaluated. A trip time model was developed for this evaluation through field studies. The model was applied on ten trips to collect solid waste bins and its transportation to disposal site in the city of Ilorin, Nigeria. The results of the model for both modes were compared and Showed that at 5 % significance level,.the trip time for the conventional mode was greater than the trip time for the exchange container mode. Also, the exchange container mode resulted in haul distance reduction by 3 to 15% and trip time reduction by 2.5 to 13 %. This reduction could help in improving logistics and also reduce the negative, impacts associated with collection operation.

Hydrodynamic Simulation of Flood wave using Dam Break Analysis in Hilly Terrain(Journal of Indian Association for Environment Management)
(Ritesh Vijay, Garima Jain Apurba Gupta,30,1,37-43,Year : 2003)
|
A majority of river development projects forcing creation of a dam for hydroelectric generation, water supply, and/or recreational purposes warrants in-depth study on consequences of dam failure. The objective of this study is to assess the impact of such a catastrophic event due to the resulting surge wave in downstream of the dam. The study comprises hydrodynamic modeling of failure of a dam in hilly terrain using one dimensional dam break analysis to visualize a maximum credible failure (MCF) scenario due to 100-year return flood and breach formation. In this simulation, two bridges, confluences of two rivers and outflow from a powerhouse meeting in the downstream within the study area have also been considered. The simulation results include critical parameters like maximum flood discharges, maximum water levels and flood arrival time which are critical for the prediction of inundation in the downstream of the dam. The results may also be used to design protective measures to ensure the adequate security of the areas likely to be affected, as well as to develop flood warning system and emergency evacuation procedures.
