Environmental Effect of Using Polluted Water in New/Old Fish Farms

InTech eBooks (2011)

Yasser Hamed Sh. Salem Abu Muhammad Shajaat Ali A. Sheshtawi

One of the most dangerous hazards affecting the environment situation in arid and semiarid countries like Egypt is the water and soil pollution. Due to the lack of fresh water for irrigation, countries in arid and semi arid areas are forced to use marginal waters for irrigation and raising fish. The effect of using such kind of low quality water is rather dangerous on the environmental situation. Besides, countries like Egypt are facing great problems to get rid of untreated waste water and industrial disposal in addition to drainage water. The spill of such kind of waters in drains and lakes will cause great problems to the eco-system and environment in general. What will make the problem more complicated is the use of these waters for irrigation or raising fish due to lack of fresh waters. The using of polluted water in fish farms has a very dangerous environmental effect on soil and ground water. The water level in fish farms is higher than the original land level. Consequently, water flows from fish farms to the adjacent land and cause problems if the water was polluted. Bahr El-Baqar drain is considered as one of the most polluted drains in Egypt (Abdel-Shafy & Aly 2002). It receives and carries the greatest part of wastewater (about 3 BCM/year) into Lake Manzala through a very densely populated area of the Eastern Delta passing through four highly populated Governorates. Unfortunately, at the last decades, great areas on both sides of the drain were using its polluted water for irrigation and raising fish. As a polluted drain with high risk to the surrounding environment, Bahr El Baqar has received considerable concern by many scientists. Ali et al. (1993), Abdel-Azeem et al. (2007) studied the effect of prolonged use of drain water for irrigation on the total heavy metals content of south Port-Said city soils. They found that using such kind of water will cause high concentration of heavy metals in soil and plants roots and shots. Water quality, chemical composition, and hazardous effects on Lake Manzala water and living organisms caused by Bahr El-Baqar drain water has also been studied by several investigators like: Rashed & Holmes (1984), Khalil (1985) and Ezzat (1989). Special attention has been paid to the effect of environmental pollution from microbiological and toxicological points of view (Zaki 1994). Fish farms located on both sides of the Bahr El-Baqar drain are using the polluted water for rising fish since long time ago. Furthermore, many agricultural lands located in these areas are also using such kind of water for irrigation. The hazardous of such kind of water on

Visualizing Subsoil Structure for Evaluating the Efficiency of Mole Drain in Heavy Clay Soils Using Geo-electrical Methods

Research Square (Research Square) (2022)

Akram Aziz Tamer E. Attia Yasser Hamed Tarek Selim

Abstract Geo-electrical surveys have been conducted on three newly reclaimed farms located on the northeastern corner of the Nile Delta, Egypt. These farms always suffer from various soil salinization problems. The surveys include measuring the natural Spontaneous Potential (SP) of the soil, apparent Resistivity Gradient (RG), and Electrical Resistivity Tomography (ERT). The study aims to image the soil structure and evaluate the effectiveness of the traditional Mole Drainage (MD) systems that are customarily utilized to reduce soil salinity of the farms in this region. Integrating the results of the surveys conducted on the first farm shows that the subsurface heavy clay-bed is very close to the topsoil. This proximity reduces the role of the MD in draining the soil. On the second farm, the clay-bed did not reach the soil surface of the farm, and a significant reduction in soil salinity levels nearby the Mole drains was observed. However, the limited thickness of the root zone was not sufficient to plant deep-rooted vegetation. Repeating the ERT measurements on the third (barren) farm revealed a severe defect in the farm drainage network, where the slope of the clay-bed opposes the main direction of the surface drainage system of the farm. This has resulted in groundwater accumulation and a frequent occurrence of waterlogging.Eventually, the efficiency of any drainage network does not depend solely on its surface maintenance. It is important to figure out the subsurface conditions of the soil as well. The methods have proven to be effective and applicable tools in imaging soil subsurface conditions nondestructively, even in lands characterized by high clay content.

Field experiment and numerical simulation of point source irrigation with multiple tracers

PLoS ONE (2018)

Tarek Selim Fethi Bouksila Yasser Hamed Ronny Berndtsson Aki√ßa Bahri

Dyes like Brilliant Blue have similar adsorptive behaviour as some organic contaminants, e.g., pesticides. Bromide ions, on the other hand, move much like NO3-N (fertilizer) in soil. Consequently, by using these two tracers, it is possible to in a general way mimic how organic contaminants and fertilizers may move through soils. Three plots with sandy soil in semiarid Tunisia were irrigated during three successive hours using a single irrigation dripper and high-saline solution (10.50 dS m-1) containing dye and bromide. Fifteen hours after cease of infiltration, horizontal 5 cm trenches were dug in the soil and dye pattern, bromide concentration, and soil water content were recorded. Preferential flow occurred to some degree, however, it did not dominate the solute transport process. Therefore, drip irrigation can be recommended to improve plant culture for a better water and soil nutrient adsorption. Numerical simulation using HYDRUS-2D/3D was performed to replicate the field experiments. Observed soil water contents before and after infiltration were used to run an inverse parameter estimation procedure to identify soil hydraulic parameters. It was found that for both field experiments and numerical simulations the mobility of bromide is different from the mobility of dye. The dye was retarded approximately twice by volume as compared to bromide. The simulation results support the use of HYDRUS-2D/3D as a rapid and labor saving tool for investigating tracers’ mobility in sandy soil under point source irrigation.

Recent Advances in Fish Farms

InTech eBooks (2011)

Faruk Aral Zafer Do Zafer Doğu Erdinç Şahinöz Julio César Wasserman

The world keeps changing. There are always risks associated with change. To make careful risk assessment it is always needed to re-evaluate the information according to new findings in research. Scientific knowledge is essential in determining the strategy for fish farming. This information should be updated and brought into line with the required conditions of the farm. Therefore, books are one of the indispensable tools for following the results in research and sources to draw information from. The chapters in this book include photos and figures based on scientific literature. Each section is labeled with references for readers to understand, figures, tables and text. Another advantage of the book is the "systematic writing" style of each chapter. There are several existing scientific volumes that focus specially on fish farms. The book consists of twelve distinct chapters. A wide variety of scientists, researchers and other will benefit from this book.

Modeling Solute Transport by DLA in Soils of Northeastern Egypt

PLoS ONE (2015)

Yasser Hamed Hiroshi Yasuda Magnus Persson Ronny Berndtsson Xin‐ping Wang

Arid soils in Egypt display large variability in solute transport properties, causing problems in soil management. To characterize this variability, dye infiltration experiments were conducted on four plots representing three main soil types in northeastern Egypt. The plots represented both cultivated and uncultivated land use. The observed dye patterns displayed a large variability and especially the clay soils indicated a high degree of preferential flow. The loamy sand and sandy soils displayed a more uniform dye distribution indicating more homogeneous soil properties. The observed dye patterns were modeled using a diffusion limited aggregation (DLA) model. The DLA is a random walk model where model parameters can be optimized using genetic algorithms (GA). The DLA model reproduced the observed dye patterns for all soils in an excellent way. The best fit was obtained with a specific combination of directional random walk probabilities Pu, Pd, Pr, and Pl for each plot (correlation 0.97–0.99). To account for soil layers with different hydraulic properties a two layer DLA model was developed. For all plots the Pu (upward random walk probability) was higher for the upper more homogeneous soil layer. The overall results showed that spatial variability resulting from solute transport for the investigated soils can be modeled using a DLA approach.

Comparison of soil salinity and solute transport for different cultivated soil types in northeastern Egypt / Comparaison de la salinité du sol et du transport de solutés pour différents types de sols cultivés du nord-est de l'Egypte

Hydrological Sciences Journal (2008)

Yasser Hamed Ronny Berndtsson Magnus Persson

Abstract The soil salinity distribution and solute transport properties of three different soil types were investigated and compared within a project area in northeastern Egypt. For this purpose, dye tracer experiments and salinity sampling were carried out. The resulting salinity maps showed that the soil salinity in the cultivated western site of the project area is 8–10 times higher than that in the cultivated eastern site. However, the cultivated soil displayed significantly lower salinity with higher uniformity as compared to the uncultivated soil. The preferential flow phenomenon was less apparent in the cultivated soil. This is mainly due to tillage which disrupts the structure of the soil so that deep cracks are no longer connected to the soil surface. This reduces the risk for groundwater contamination through preferential flow. The study showed that careful and continuous monitoring of the salinity status is needed now and in the future.
