“…The development of TUNA-WQ is based upon extending the capability and robustness of the in-house tsunami simulation software TUNA [8,9]. The development intended in this research is the enhancement of the TUNA model to include tidal dynamics and pollutant transport simulations to enable the simulation of ecological and water quality scenarios in estuaries and open sea.…”

Abstract. Increasing demand for potable water coupled with diminishing water resources due to pollution and unsustainable utilization create a challenge in providing sustainable sources of potable water. It is therefore vital to protect our existing water resources from pollution while achieving economic and social development. Water quality models are useful tools for simulation of pollution levels, due to pollutants released into a certain water body. Mitigation measures for reducing the adverse environmental impact can be explored via model simulations. These model-predicted impacts and suggested mitigation measures provide a basis for environmental management agencies to make the right decisions. In this paper, we present an in-house two-dimensional water quality simulation model codenamed TUNA-WQ. As an in-house model, TUNA-WQ can be revised and adapted to broaden the applicability and improve the robustness of the model. Further, proprietary models are costly to maintain for individuals without access to institutional support. We begin the paper by introducing the development of TUNA-WQ, starting from specifying the equations and numerical method employed. This is followed by verification of the model through comparison with a tested water quality simulation model. To demonstrate the application of TUNA-WQ, we conclude the paper by presenting the TUNA-WQ simulated suspended sediment plumes in the top water column due to discharge from an offshore oil and gas exploration platform in the South China Sea.

“…Severely affected area at that time was Penang and Kedah (Colbourne 2005). The incident has driven lot of researches about it in Malaysia (Ismail et al 2012;Jahromi 2009;Jamaluddin et al 2010;Koh et al 2009a;Koh et al 2009b;Master, 2014;Teh et al 2009). In fact, at early years of the incident, the studies are much related to the tsunami impact assessment and tsunami warning (Aasen et al 2007;Ismail et al 2012;Koh et al, 2009b;Master 2014).…”

“…Mangroves are important coastal habitats for several ecological, economical, and protective functions (Biswas et al 2009;Cavanaugh et al 2014;Nortey et al 2016) and act as barriers against storm surges, floods and tsunamis (Alongi 2008;Kulkarni 2009;Teh et al 2009;Yanagisawa et al 2009;McFadden et al 2016). They have a highly efficient nutrient retention mechanism (Alongi 2002) and serve as breeding and nursery grounds for a wide range of aquatic and terrestrial species (Kumara et al 2010).…”

Monitoring of Eco-Restoration of Mangrove Wetlands through Time Series Satellite Images: A Study on Krishna-Godavari Delta Region, East Coast of India

Comparative analysis of time series satellite images spread over the past four decades indicated significant changes in the mangrove environment of the Krishna-Godavari twin deltas along the east coast of India. We analyzed Landsat-MSS, TM and ETM images from 1977, 1990, and 2000, respectively, and Indian Remote Sensing Satellite images from 1992, 2001, and 2013, which indicated that the mangrove cover in the region increased from 35,058 ha in 1977 to 39,283 ha by 2013. In spite of loss of mangrove vegetation over 8,036 ha due to coastal erosion, deforestation, decline and aquaculture encroachments, several mangrove-restoration projects taken up during 1991-2008 led to an overall increase in its area. Various mangrove eco-reforestation techniques were adapted in the region.
