Spatial and temporal variations of hydrodynamics and sediment dynamics in Indus River Estuary,Pakistan


Noor Ahmed Kalhoro et al. View all

Ecosystems and Natural Resources Management

Field investigations were conducted to study the seasonal variation of hydrodynamics and sediment transport in Indus River Estuary (IRE), Pakistan. The data of water levels, currents, salinity, and suspended sediment concentration (SSC) were collected hourly covering both wet and dry seasons. Tidal...

Estimation of changes in the Dead Sea surface water area through multiple water indices and geospatial techniques


Majed Mahmoud Ibrahim et al. View all

Water Resources Management

The study calculated the changes in the Dead Sea surface area from 1984 to 2019. The satellite images of 1985, 1990, 2000, 2010, and 2019 were classified by applying four different methods to estimate the changes in the Dead Sea surface water area. The methods included normalized difference water...

Quantifying the impact of urban runoff injection on groundwater Enhancement in a semi-arid environment using SWMM and MOFLOW Model


Reza Ghazavi et al. View all

Water Resources Management

In the urban area, surface runoff can be utilized effectively to improve groundwater table through rainwater harvesting. The main aims of this study were to:1) investigate the potential of the surface runoff to inject into Urmia aquifer and increase groundwater recharge of this aquifer using SWMM -...

Detoxification of As(III) in Aqueous Media by Using Photo-Fenton Method


Endang Tri Wahyuni et al. View all

Water and Wastewater Treatment

In this paper, photo-Fenton method has been systematically examined to oxidize the toxic and mobile As(III) in the solution by •OH radicals resulted from the reactions between Fe2+ and H2O2 under UV light, to form the less toxic and insoluble As(V). The effects of various experimental parameters...

Deep neural networks for climate relation extraction


Jian Zheng et al. View all

Climate change mitigation and adaptation

Climate data composes of time series and space series with unknown. These unknown series contains complex co-variation relations of climate data. The extraction of these relations is essential for further revealing the complex representations between time series and space series in climate data. As...

Purification of Biogas From Tofu Waste using Zeolite and Activated Carbon (AC) as Adsorbent


Mochamad Arief Budihardjo et al. View all


Substitution of fossil fuel into alternative energy sources, such as biogas, needs to be applied to prevent various problems in the environment. Biogas purification can be an alternative technology to improve the quality of biogas, which increases the heat value by reducing CO2. Purification can be...

A New Approach to Assess Wind Potential


Zaheer Uddin et al. View all

Sustainable Energy

Weibull Cumulative Distribution Function (C.D.F.) has been employed to assess and compare wind potentials of two wind stations Europlatform and Stavenisse of The Netherland. Weibull distribution has been used for accurate estimation of wind energy potential for a long time. The Weibull distribution...
