Materials and Methodologies two. Materials and Methodologies two.1. Study Area 2.1. Study Location The Yellow River basin features a vast territory, which crosses 3 key geographical The Yellow River basin includes a vast territory, which crosses 3 major geographical terrains in China (Figure 1). The complete length of your river course for the mainstream is terrains in China (Figure 1). The full length of your river course for the mainstream is 5464 5464 km, and also the annual imply organic runoff volume of your complete river for many years is km, and the3 annual imply all-natural runoff volume of the full river for a lot of years is 58 58 billion m -1 , which only occupies two of river runoff volume in China [26]. billion m3 -1, which only occupies 2 of river runoff volume in China [26].Figure 1. The upper and middle Yellow River drainage method diagram. Source: China Water Sources Yearbook, 2018. Figure 1. The upper and middle Yellow River drainage program diagram. Supply: China Water Sources Yearbook, 2018.The Yellow River supply region maintains the vital flowing water with the Yellow The Yellow maintains the essential flowing water on the Yellow 3-Chloro-5-hydroxybenzoic acid Cancer River’s life by taking 49 runoff volume on the all round drainage basin. With worldwide cliRiver’s life by taking a a 49 runoff volume with the general drainage basin. With global climate warming, the annual typical temperature the Yellow River area has the mate warming, the annual average temperature inin the YellowRiver location has precisely the same trend. The snow line rises; the ground temperature trend. The snow line rises; the ground temperature rises; the elevation of the decrease bound for frozen earth rises, which brings series of ecological troubles. Water for frozen earth rises, which brings a series of ecological complications. Water and soil loss are the classic ecological challenge within the Yellow the standard ecological problem in the Yellow River, and this sort of problem is most apparent on the Loess plateau. The soil layer the Loess plateau is profound, plus the the apparent on the Loess plateau. The soil layer in inside the Loess plateau is profound, and soil soil property is loosening. The terrain is crushed; the rainstorm is frequent, water loss house is loosening. The terrain is crushed; the rainstorm is frequent, water and soil and soil loss are extreme, the principal supply of sediment of your Yellow Yellow River brought on are severe, which is that is the main supply of sediment of your River and hasand has triggered the heterogeneous scenario from the flow and sediment. The region of your upper as well as the heterogeneous situation in the flow and sediment. The area from the upper and middle middle accounts for 97 of 97 of region. The riverbed stretching for numerous kiloreaches reaches accounts forthe totalthe total region. The riverbed stretching for hundreds of kilometers in the lower reaches of the River River is than the ground o.
