Modeling the Hydrodynamics and Salinity of El-Burullus Lake (Nile Delta, Northern Egypt)

Abstract

Abstract-This study investigates issues related to hydrodynamics in Lake El-Burullus and flow patterns therein. Burullus Lake is the second largest lake in the northern Egyptian coast with a total area of 410 km 2 . It was utilized Delft3D-flow module to develop a field validated hydrodynamic model. The shallow brackish Lake is mainly affected by uncontrolled creeping of development areas and growing inflow of untreated agricultural, municipal and industrial drainage water. The developed model was used to examine a potential mitigation alternative by decreasing the pollutant loads that enter the Lake i.e. diversion of existing drains. In this fashion the creation of a new development area near-by may be feasible. In addition, the effects of hydrodynamics on pollutant dispersion either from an individual drain or all drains together. The results of this study will be the base for the water quality modeling stage. Actually, this work is the first stage of an integrated Lake management. The study concluded that the developed model efficiently simulated the hydrodynamics of the Lake which can act as an effective decision support tool for improving the environmental conditions in the surroundings.

“…For example, according to El-Adawy et al (2013), the residence time is higher than 60 days in Lake Burullus western sector.…”

Coupled Hydrodynamic-Water Quality Model for Pollution Control Scenarios in El-Burullus Lake (Nile Delta, Egypt)

“…The first stage of the research included creating a validated hydrodynamic model using available data sets. The model was used to examine a potential mitigation scenario by decreasing the pollutant loads entering the lake, i.e., diversion of existing inflows (El-Adawy et al, 2013). This study forms the second stage of an integrated management strategy for El-Burullus Lake, which assesses the current situation and employs scenario analysis of potential pollution control measures.…”

“…The calibration and validation of the hydrodynamic model utilized components of the hydrodynamic data sets (drain discharge, water leveland tidal variation) and meteorological data sets (wind vectors, solar radiation, relative humidity and temperature). In addition, geometric data (bathymetry, land boundaries, island boundaries and inlets positions) were used in determining the closed and open boundaries of the model and in creating the grids (El-Adawy et al, 2013).…”

Hydrodynamic and Inundation Modeling of China’s Largest Freshwater Lake Aided by Remote Sensing Data

“…In this study, the Delft3D-FLOW numerical modeling system, which has been widely applied in two-dimensional hydrodynamic simulations of lakes [24][25][26][27][28][29], is used to set up the two-dimensional hydrodynamic model of Poyang Lake. This system has been developed for the modeling of unsteady water flow, temperature, salinity and cohesive/non-cohesive sediment transport in shallows seas, estuarine and coastal areas, rivers and lakes [30].…”
