    Euphrates and Tigris Rivers

    The word Mesopotamia comes from the Greek word “mesos” means middle and “potamos” means river. So Mesopotamia means an area that lies between two major rivers, namely the Euphrates and Tigris rivers. This area is better known as the “crescent moon” because the shape of the area resembles a crescent moon. Like the Nile in Egypt, the Euphrates and Tigris rivers also frequently flood so that they can benefit the lives of the surrounding communities. Initially, the rivers were swamps and even became a hotbed for malaria. However, it is the people who convert and process them into irrigation so that they can irrigate agricultural areas. Soil fertility and other…

    Nile Valley Civilization “ A Gift for Egypt”

    Egypt is one of the highly civilized countries in the past around 4000 BC. This is because Egypt has a natural state which is one of the conditions for the advancement of a culture, namely the Nile river. The Greek historian Heredotus once visited Egypt around 350 BC said “without the Nile Egypt could not have advanced, the River Nile was a gift to Egypt“. The statements of Heredotus can make it clear that it was on the Nile that ancient Egyptian civilization began. The Nile is the longest river in the world, reaching 6400 kilometers, flowing from south to north and emptying into the Mediterranean. There are 4 countries…

    The Source of Civilization Starting from the River

    Rivers are the source of life for not only humans, but all living creatures created by God that exist on this earth. When talking about the early civilization of mankind, it must be started from rivers, especially the valleys of large rivers. Some common examples are the Nile River Valley (Egypt 4000 BC) Africa, the Euphrates and Tigris River Basin (Mesopotamia-Iraq 3000 BC) West Asia, the Indus River Valley and the Ganges River (India 3000 BC) Asia, the Huang Ho River Valley (Yellow) China North. The incident started when there was a flood, the rivers carried sediment. Sediment, which is a material in the form of a powder found in…

    “Embung”, A Small Dam

    Have you ever heard the word “Embung”? In Indonesian, embung can be interpreted as a small dam. Dams are generally divided into two, namely large dams and small dams. The embung itself is a building that functions to raise the water level but does not meet the requirements of a large dam because it has a capacity of less than 500,000 cubic meters. Embung is also defined as a water conservation building in the form of a basin in a river or water flow in the form of land fill, rock fill, concrete and / or stone masonry that can hold and hold water for various purposes. The embung to…

    Dujiangyan, World’s First Irrigation System

    Talking about irrigation, irrigation problems cannot be separated from agricultural cultivation. This has long been realized by humans, especially farmers. According to stories in ancient times, when agricultural land was close to abundant water sources such as springs or rivers, irrigation was carried out by channeling water to agricultural land. But it can also be done by bringing water directly to agricultural land, which people call this method watering. In the world, the first irrigation system was built around 250 M named Dujiangyan which was built by Li Bing, a Chinese hydrologist, during the Qing Dynasty. Remarkably, until now this irrigation system can still be used. Li Bing found a…

    River Water Quality After The Eruption Of Mount Merapi In 2010

    The research was conducted in 2011 with a study of the Mount Merapi area located in Yogyakarta, Indonesia. This study is to determine how far the post-eruption conditions are to the water quality of the Opak River, based on the condition of the Opak River which is filled with Merapi material, especially after the lava flood which carries the material from the eruption to the downstream part of the Opak River. As a result of the lava floods that occurred during the rainy season in 2010/2011, material from the eruption in the upper reaches of the Opak River and the Gendol River filled the bodies of the two rivers. Silting…

    The Influence of Watershed Based Climate Change

    Global warming is no longer a problem for the future, but has become a problem that is being faced now. Several studies have proven that extreme climatic events are inevitable. The impact of extreme climate events is expected to get worse if the environmental damage, especially the damage to forest cover in the rain catchment area in the watershed, gets bigger. In general there is a decrease in the chance of rainfall exceeding the critical limit associated with flooding especially in the central part of a city. Meanwhile, during the dry season there is an increase in rainfall which will reduce the possibility of future drought. A watershed provides natural…

    The Concept of Eco-Hydraulics in Erosion Control

    Eco-engineering is one of the components in ecological-hydraulic (eco-hydraulic) technology and its principles can also be used to tackle abrasion of beaches, lakes and so on. River or lake cliff protection buildings that are always used in conventional cliff protection techniques are cliff pavements with filled or empty stone pairs. This construction covers the entire cliff face. This kind of building will directly shorten the river flow and reduce the wall roughness factor (the walls become relatively smooth). Besides that, it can cause difficulties for river or lake biota to migrate or move horizontally, it can even eliminate the possibility for all types of river or lake biota on the…

    Water Conservation and River Management

    One form of water resource management is conservation. How do you conserve the water? 1. Watershed Conservation The exploitation of natural resources of land, forest and water has resulted in the increasing number of critical lands. The impact will change the hydrological cycle such as flooding, drought, and increase the rate of erosion and sedimentation. To overcome the process of erosion and sedimentation, soil and water conservation techniques are needed. Some of the methods applied are vegetative methods, namely the use of plants to reduce the destructive power of falling rain, thereby reducing surface runoff and erosion. Reforestation is one of these methods. The second method is the civil engineering…

    Water Resources Problems

    Water resources are resources that, although until now they are still included as renewable resources, in fact water resources in the world are increasingly depleting. Yet everyone knows that water in life is irreplaceable and is a basic necessity for human, plant and animal life. The availability of water is very necessary, but it must be in sufficient quantity, not excess or lack. In its development, there are several crucial problems that require immediate follow-up and integrated handling, namely: Weak coordination among relevant agencies and lack of accountability, transparency and participation of stakeholders in water resources management. Increased conflict due to the increasingly limited availability of water while water needs…
