MODELING LEACHATE MIGRATION FROM A LANDFILL December‚ 2003 1 INTRODUCTION A two-dimensional‚ steady state transport modeling using MODFLOW/CTRAN was carried out following the particle tracking calculations to simulate potential contamination for leachate migration from Gibraltar landfill. Gibraltar landfill was a disposal waste site in Bogotá (Colombia) until 1988. The site presented problems related to contamination for leachate migration after its closure‚ since the operation

P5- Explain dysfunction in relation to water balance and its possible treatments. M3- Discuss dysfunctions in relation to water balance and its possible treatments. For P5 and M3‚ I am going to explain the dysfunctions that relate to the balance between water intake and the disturbance of water output. Then I am going to discuss it in more detail. Oedema‚ also known as dropsy‚ is one of the dysfunctions and this is when there is too much fluid retention in the body. In other words‚ the accumulation

“GROUND WATER AND ARTIFICIAL RECHARGE IN GUJARAT” ABSTRACT Though groundwater is an important source of irrigation in India‚ its availability is non-uniform in space and time. In Saurashtra region of Gujarat state‚ problem of groundwater depletion has arisen due to high withdrawal than rate of replenishment of groundwater. This also resulted in seawater intrusion in coastal areas at very high rate. The water harvesting and groundwater recharge activities played an important role in increasing the

The Negative Flood Effects The negative impact of floods is very uncontrollable. During a long period of dry weather‚ it suddenly begins to rain. Rainfall refills the water that supplies and provides a drink for every living thing. It also helps with drought and washes pollutants from the atmosphere. However‚ streams and rivers can’t handle the heavy rain so water overflows and produces a flood. As a result‚ they caused economic losses‚ damage in urban and rural communities and damage the environment

FLOODING IN BANGLADESH CAUSES OF THE FLOODS There are several physical reasons why Bangladesh suffers from flooding almost every summer; It has the perfect conditions for such as disaster- this is because : • tropical cyclones from the bay of Bengal bringing heavy rain and storm waves in late summer • 70% of the land of the total area is less than 1 metre above sea level • The total annual rain falls in the summer of Dhaka is almost 2000mm • Rivers lakes and swamps cover more than 10% of the

Survey on Water Scarcity & Conservation Water is becoming a limited natural resource in the world. In an article published on National Geographic website about “Fresh Water Crisis” [1] it has mentioned that out of the 70% of water which is covering the earth‚ only 2.5% is suitable for drinking and just 1% of fresh water is easily accessible. In the same article the author talks about how people are wasting this limited resource. The growing scarcity of water is due to the rapid growth of

Watershed Characteristics 1. Drainage Area the drainage area and it is the most important watershed characteristic for hydrologic analysis. It reflects the volume of water that can be generated from a rainfall. Thus the drainage area is required as input to models ranging from simple linear prediction equations to complex computer models. Once the watershed has been delineated‚ its area can be determined‚ either by approximate map methods or by GIS. 2. Drainage Density The drainage density‚ D

The Red River located near Fargo‚ North Dakota‚ has a history of flooding due to abnormal climate conditions. Every year precautions are taken to help minimize damages that are caused by the flooding. There are four main reasons that contribute to the river flooding so often. These main reasons for the floods are: Synchrony of discharge with spring thaw‚ ice jams‚ glacial lake plain‚ and the decrease in gradient downstream. The first reason that contributes to the river flooding so often is the

CHAPTER II REVIEW OF RELATED LITERATURE AND STUDIES It is an integral part of the study. It may also be a required part of proposals. The main purpose is to analyze scientific works by other researchers that the researchers used for investigation critically. It is also secondary sources‚ and as such‚ do not report any new or original experimental work. Basically this part of the study focuses on the foreign and local types of water level monitoring system and also the articles involved and necessary
