    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…

    Travel to the Bahamas

    Bahamas comes from the Spanish “baja mar” which means “shallow sea water”. The Bahamas is a stable and developing country with an economy that is heavily dependent on tourism and offshore resources. Judging from the typology, all the islands in the Bahamas contain calcium carbonate, which is produced from coral reef organisms, mollusks, echinoderms, and mollusks where this process is thought to have started since prehistoric times. One of the unique beaches in the Bahamas is the Pink Sands beach, which is located on Harbor Bahamas Island. The pink sand on this beach comes from Foraminifera, which are small marine animals with bright pink or red shells. Land use in…

    Types of Estuaria

    After telling about the estuary, the mother from of beach, we need to know more about its types. From a morphological point of view, estuaries can be classified into several categories based on their shape and geological development since their inception since the ice age. Based on geological criteria, there are three main types of estuaries based on the condition of the connecting channel to the ocean which functions to control tidal exchange. The three criteria include estuaries that are tide-dominated (tide-dominated), wave-dominated (estuary) and which are relatively closed (intermittently closed). 1. Tide-dominated Estuary Estuary which has the form of a connecting channel to the ocean which is relatively large…

    Tells About The Mother of Beach

    The estuary area deserves to be called the mother of the coast, because the estuary area is a place for nurturing, foraging for food, giving birth, raising fish and other aquatic biota. What is an estuary? Estuary is the waters of a semi-closed river estuary that are freely connected to the sea, so that sea water with high salinity can mix with fresh water from rivers. Estuary is a transitional zone between a river environment and a marine environment, so that the condition of the estuary is influenced by the character of the river that forms it (for example the amount of fresh water and sedimentation it carries), as well…

    Difference Between Disaster Management and Watershed Management

    A teacher asks students about the differences between disaster management and watershed management. The student was a bit confused in answering the question, because according to his view that the two management were different but the differences were difficult for him to describe. Actually, what is the fundamental difference between the two management? Let’s look at the reviews below. Disaster management is a series of activities carried out in the context of efforts to prevent, mitigate preparedness, emergency response and recovery related to disaster events. Losses and risks that can be reduced or reduced as well as accelerating the post-disaster recovery process are the goals of disaster management. This is…

    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…
