A new study for World Resources Report describes recent changes in approach to flood control along the Yangtze River:. Replies. 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. ... Yangtze Flooding Case Study. The Yangtze River. 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. 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. 1998 alone, more than 4,000 ... flood control that the river/lake linkages have historically provided, helping to reduce future flood damage. The present study focuses on simulating sediment flux for 1998 big-flood with 60-year recurrent period in the Yangtze River catchment. Figure 4.1 57 The parameters derived from navigation charts. 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. Highlights A spatial model was developed to mapping the flood mitigation function of ecosystem in the Upper Yangtze River Basin (UYRB). 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. Reply. 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. Figure 4.2 58 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 ��� 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. Reply Delete. However, judging from the rainstorm duration, intensity and impact range, the disaster in the 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. What percentage of the watershed's original tree cover has been removed? 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. 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.

A computational case study is presented of the flooding in urban Jiujiang due to the Yangtze River dike break in August 1998. The monetary value of the flood mitigation service was calculated by formulating an exponential function. 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.

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. 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.
