Figure 3.4 45 The location of Three Gorges Dam. Although the water level in the Yangtze River, the country's largest, remains high above the alert level, Tang is feeling less worried about the flooding this year than that in 1998. This framework was applied to the study of the annual maximum flood frequency of the Yichang gauging station 44 km downstream of the Three Gorges Dam over the period from 1470 to 2017. A basin wide severe flood occurred in the Yangtze River valley in 1998. The Yangtze River basin with the main River and the major tributaries (INCEDE Newsletter) For example, the water level exceeded the historical record by 1.74 m in Jianli, and 1.85 m in Lianhuatang. The 1998 Yangtze River Flood sounded the alarm for Chinese Government to take actions to protect her environment for Learn vocabulary, terms, and more with flashcards, games, and other study tools. This paper aims to compare the Rhine-Meuse-Scheldt Delta in Europe and the Taihu Basin part of the Yangtze River Delta in China from a long-term historical perspective. Urbanized deltas are among the most prosperous and populated regions in the world, but also the most vulnerable.

The flood caused a direct economic loss of more than 200 billion yuan. Nonstationary Frequency Analysis of Censored Data: A Case Study of the Floods in the Yangtze River From 1470 to 2017. A shallow water hydrodynamic model was deployed based on the weighted average flux - total variation diminishing (WAF-TVD) finite volume algorithm. Replies. On the basis of close correlation between discharge and sediment load recorded on the daily base of the past decades at a series of hydrological gauging stations located in the Yangtze River, the sediment rating curve of 1987/1988 was selected to ��� A computational case study is presented of the flooding in urban Jiujiang due to the Yangtze River dike break in August 1998. ... 1998 Yangtze River Flood - Duration: 10:02. A shallow water hydrodynamic model was deployed based on the weighted average flux ��� total variation diminishing (WAF-TVD) finite volume algorithm. Catastrophic floods include: 1931, 1935, 1954, 1998. In the summer of 1998, China experienced massive flooding of parts of the Yangtze River, resulting in 3,704 dead, 15 million homeless and $26 billion in economic loss. Reply. The 1998 Yangtze River floods were a series of major floods that lasted from middle of June to the beginning of September 1998 along the Yangtze. Three gorges Dam. It is characterized high water level, large flood volume and long lasting. Yangzhong, the second-largest island on the Yangtze River, is protected by 120 km of embankment. Flooding on the Yangtze River, China. Figure 3.5 49 Sketch of levee along the middle Yangtze River. Page 1 of 35 Forest and Flood: Aftermath of the 1998 Yangtze River Flood [Graduating Essay ��� FRST 497] [XinZong You] April 15, 2012 ABSTRACT There has been a long debate over the effect of logging on flood events. and why has flooding become more frequent and severe? A computational case study is presented of the flooding in urban Jiujiang due to the Yangtze River dike break in August 1998. Bin Xiong. What percentage of the watershed's original tree cover has been removed? This is a case study video giving an amateur outlook on the flood protection management in China. Last great flood-1998, ... what are the reasons that make the yangtze river flood regularly? Figure 3.3 43 On-propose levee breaches and inundation in the 1998 flood event. This year's rainstorms in southern China are characterized by a wide range of impacts, a long duration, high intensity and incessant heavy rainfall in some regions, China Meteorological Administration said on Wednesday. Controlling Yangtze River Floods: A New Approach By Dr. Jamie Pittock and Dr. Ming Xu After nearly a millennium of efforts to control floods in the Yangtze River basin with dikes, polders and other hard engineering measures, the Chinese government adopted a radically different approach after the disastrous 1998 floods. In the case of the Thames flood ��� Figure 3.2 29 Topography of the middle and lower Yangtze River. To cope with growing uncertainty, their systematic comparison has become instrumental in building ��� Home > A Level and IB study tools > Geography > Flooding on the Yangtze River, China. A new study for World Resources Report describes recent changes in approach to flood control along the Yangtze River:. 10:02. Yangtze River flood. Xu Freddy 5,833 views. ... Yangtze Flooding Case Study. However, judging from the rainstorm duration, intensity and impact range, the disaster in the Start studying IGCSE CIE Geography: 2.2 - Rivers (Case Study) - LEDC Bangladesh Floods. Figure1. The monetary value of the flood mitigation service was calculated by formulating an exponential function. The main cause of the flood was due to above average rainfall in the region for several months before and during the summer of 1998. The present study focuses on simulating sediment flux for 1998 big-flood with 60-year recurrent period in the Yangtze River catchment. 5.0 / 5. To examine and understand the effects of the Yangtze River and local catchment on the flood stage of Poyang Lake, four years in which a severe flood event occurred, i.e., 1983, 1995, 1998, and 1999, were selected for study. Yangtze is responsible for 70-75% of all floods in China. 1998 alone, more than 4,000 ... flood control that the river/lake linkages have historically provided, helping to reduce future flood damage. Highlights A spatial model was developed to mapping the flood mitigation function of ecosystem in the Upper Yangtze River Basin (UYRB). Ecosystems reduced flood 42.8 billion cubic meters per year and 6.479 billion RMB Yuan as the value of flood mitigation. On average, several hundred people are killed every year due to flooding; floods in the 20th century have killed more than 300,000 people. PDF | On Jan 1, 2011, Jamie Pittock and others published World Resources Report China's worst flooding since 1998 occurred over the Yangtze River Valley from 30 June to 6 July 2016. 0.0 / 5. The discharge in the 1998 flood was also high, only a little smaller than the catastrophic 1954 Yangtze River flood. 0.0 / 5. This study investigated the event using a new method ��� the spectral nudging and update cycle (SN + UIC) ��� in the regional Weather Research and Forecasting model, fuller use of small���scale features by using multi���scale blending. Streamflow Prediction Using Deep Learning Neural Network: Case Study of Yangtze River Abstract: The most important motivation for streamflow forecasts is flood prediction and longtime continuous prediction in hydrological research. Most areas saw double the normal amount of rainfall during the rainy season, with certain regions seeing rainfall levels as much as nearly three times the historical average. The evolution of summer monsoon over East Asia is the result of multi-scale interactions, including the large-scale subtropical high, upper level jet and regional-scale Meiyu front, vortex, and thermal heating. Figure 4.2 58 Flood - Yangtze (China), July 1998 China, July 1998 - Seasonal summer rains have devastated vast areas of China this year, killing more than 2,000 people, destroying 2.9 million houses and ruining more than 9 million hectares of crops.
