Analisis Likuefaksi Berdasarkan Data CPT Untuk Perancangan Pondasi Di Pesisir Pantai Kabupaten Kulon Progo DIY

Yogyakarta Special Region (DIY) is an area that has a high level of seismic activity in Indonesia. This is due to various local faults near the land and its location adjacent to the subduction of the Indo-Australian and Eurasian plates. The proposed new airport is located on the coast in Kulon Progo Regency DIY. The location is dominated by the sands layer and it has high ground water levels which indicate the high potential of liquefaction. The site classes of the coast in Kulon Progo Regency is medium category (SD). Liquefaction analysis using the PGAM value of 0.4 g. Liquefaction has the potential to occur in soil layers 0 - 6 meters. The analysis shows for eartquake of ≥ 6.3 Mw has a very high category of liquefaction. The analysis results has LPI ≥ 29.30 for ground water conditions at the surface, and LPI ≥ 15.32 for ground water conditions in depths of 3 meters. Estimated soil settlements of 19.7 cm for magnitude of 8.1 Mw with ground water conditions at the surface. The use of shallow foundations at soil depths of 0-6 meters is not recommended, unless a soil improvement method is used to eliminate the potential for liquefaction.

1. Observations made on growing a series of crops in rotation over a range of static ground water-levels in a Fen peat soil are recorded.2. The crops used show differences in their reaction to ground water conditions, and the seasonal incidence of rain has an overriding influence on their performance.3. The effects of ground water-level may operate directly on the growth and development of a crop or may influence it indirectly through factors such as weed infestation, difficulties of cultivation, or the incidence of disease.

Hydrological Effects

The research deals with the geographical and hydrological location of Khartoum state within the scope of the Nubian sandstone extension, and the effects of this on groundwater. To achieve this, 9 samples were analyzed from the wells dug in Omdurman, Khartoum and Bahri to identify the structure and composition of layers and depths of water, in addition to 30 other samples for chemical analysis And the physical of some elements to know the specifications of water and its suitability for human use. The research concluded with a number of results, including that there is a difference in the components of the Nubian sandstone, as its percentage in Omdurman is 67%, the number of layers 10 and Khartoum 71% and the number of layers 16, and in Bahri 82% and the number of layers 21 and thus it is higher than Omdurman and Khartoum. Water levels vary even within the region from one well to another in Omdurman, which is located at depths of 490, 690, and 800 feet, and in Bahri, it is located at depths of 530, 690, and 725 feet, and the hose is located at depths of 340, 505, and 585 feet. Soluble, nitrite and mineral compounds are good according to Global standards for water except for a few of them, with the high level of ammonia in Omdurman and Khartoum higher than 0.1mg/l, which is an indicator of pollution.

According to the conducted research it has been found out that the direction and intensity of water and salt regimes in the irrigated land areas of the Ararat valley are related to the ground water levels, mineralization, crops᾿ species composition and to the irrigation factors. Under conditions of high level of ground water (<1.75 m) some salt accumulation is observed in the mid and surface soil strata, which can lead to the decline of soil fertility and crops productivity. Hence, it is recommended to implement irrigation and leaching activities in spring and autumn seasons along the mentioned land areas increasing the irrigation rate in 1.5 times.

Climate change and its impact on water resources is the problem of the times. Therefore, this study is concerned with the subject of climate change and its impact on the water ration of the grape harvest in Diyala Governorate. The study was based on the data of the Khanaqin climate station for the period 1973-2017, (1986-2017) due to lack of data at governorate level. The general trend of the elements of the climate and its effect on the water formula was extracted. The equation of change was extracted for the duration of the study. The statistical analysis was also used between the elements of the climate (actual brightness, normal temperature, micro and maximum degrees Celsius, wind speed m / s, relative humidity% The results of the statistical analysis confirm that the water ration for the study area is based mainly on the X7 evaporation / netting variable, which is affected by a set of independent variables X1 Solar Brightness X4 X5 Extreme Temperature Wind Speed 3X Minimal Temperature and Very High Level .
