برآورد منطقی نفوذپذیری مقایسه ای با استفاده از دانه بندی رسوب

Knowing about the condition and permeability of different natural surfaces is very important for many different projects and plans, especially studies related to water resources. Since the most important factor affecting permeability is the grain size, many researchers have used the data related to soil and sediment granularity to estimate permeability. This method is comparatively cheaper and not dependent on other factors such as hydraulic boundaries. If the distribution of sediment and soil particles is uniform, the use of permeability estimation relationships can increase the measurement speed and reduce costs. Nevertheless, if the purpose of measuring and measuring permeability is to compare the state of permeability of different areas with each other or to determine the level of decrease or increase of permeability over time, even with non-uniform sediments, use relationships and tables to estimate permeability using granularity. Sediment and soil particles are not limited and in some cases it will be completely justified. Therefore, to estimate the permeability in areas and areas where the goal is to compare before and after certain operations (such as dewatering operations in flood spreading areas), sediment grading can be used, which significantly reduces the costs of measuring It will result in direct capture.
