    Watershed Hydrological Function

    Many people cannot distinguish between watersheds and rivers. They still think that the watershed is an area near the river. Even though the watershed coverage is not that narrow. In managing a watershed, it requires a deep understanding of the watershed itself. The definition of DAS based on the function of a watershed is divided into several obstacles, firstly the upstream watershed is based on a conservation function which is managed to maintain the environmental conditions of the watershed so as not to experience degradation. The conservation function can be seen from the condition of watershed vegetation cover, water quality, ability to store water (discharge) and rainfall. Second, the middle…

    Coastal tourism ; Depok Beach

    Depok Beach is located in Bantul, Yogyakarta, Indonesia. The landscape type of the Beach is marine (coastal). Generally, coastal morphology consists of bays, berms, crest berms, and beach scarp. The coastal region is included in marine deposition with its material in the form of sand called shoreline. The sand in the beach area is black because it is sand carried from Mount Merapi, so the Depok coastal area is an ecological unit with the Merapi mountains. Sand types on shoreline are softer than other beaches because of the effect of the sorting process. The lithology composing the coastal area on Depok Beach is dominated by medium sized sand deposits and well-sorted. These loose deposits are composed of volcanic lytic (andesite and tuff sandstone). The character of the waves on the shoreline is plugged into large waves due to the speed of the wind that blows big. The study states that in August-September, wind speeds range from 3.33-10,094 m / sec with directions that change…

    Irrigation Principle

    Many think that irrigation is a new discovery in human civilization. Not many people know that irrigation is a cultural heritage that has long been practiced and practiced in civilizations thousands of years ago. Irrigation has been practiced by humans for thousands of years by taking water from available water sources such as groundwater or rivers and then transporting it to land which requires additional water. Collection, transportation and addition of water are carried out in different ways, depending on the level of progress and mastery of technology and local culture. The technology applied in irrigation activities can be in the form of very simple and local technology, to high…
