A coupled hydro-meteorological modeling system is established for real-time flood forecast and flood alert over the Huaihe River Basin in China. The system consists of the mesoscale atmospheric model MC2 (Canadian Mesoscale Compressible Community) that is one-way coupled to the Chinese Xinanjiang distributed hydrological model, a grid-based flow routing model, and a module for acquiring real-time gauge precipitation. The system had been successfully tested in a hindcast mode using 1998 and 2003 flood cases in the basin, and has been running daily in a real-time mode for the summers of 2005 and 2006 over the Wangjiaba sub-basin of the Huaihe River Basin. The MC2 precipitation combined with gauge values is used to drive the Xinanjiang model for hydrograph prediction and production of flood alert map. The performance of the system is illustrated through an examination of real-time flood forecasts for the severe flood case of July 4―15, 2005 over the sub-basin, which was the first and largest flood event encountered to date. The 96-h forecasts of MC2 precipitation are first evaluated using observations from 41 rain gauges over the sub-basin. The forecast hydrograph is then validated with observations at the Wangjiaba outlet of the sub-basin. MC2 precipitation generally compares well with gauge values. The flood peak was predicted well in both timing and intensity in the 96-hour forecast using the combined gauge-MC2 precipitation. The real-time flood alert map can spatially display the propagation of forecast floods over the sub-basin. Our forecast hydrograph was used as opera-tional guidance by the Bureau of Hydrograph, Ministry of Water Resources. Such guidance has been proven very useful for the Office of State Flood Control and Drought Relief Headquarters in operational decision making for flood management. The encouraging results demonstrate the potential of using mesoscale atmospheric model precipitation for real-time flood forecast, which can result in a longer le

Using alert and Action Expected Times of Delivery in Prevention of Prolonged Labor

引用

Open Journal of Obstetrics and Gynecology 2015年第14期5卷 813-818页

作者： N. F. B. Tandu-Umba G. Kalombo Muamba Department of Obstetrics and Gynecology University Clinics Kinshasa DR Congo

Background and Objective: Although globally admitted as the most valuable tool to prevent prolongation of labor, the partogram has failed to be commonly used. This is due to its alleged complexity. Based on the simplified model proposed by Debdas, the so called paperless partogram, we aimed at evaluating the ability of only using the alert and action lines to prevent prolongation of labor. Methods: This was a cross-sectional study including labor records of women delivered at King Baudouin Hospital of Kinshasa (secondary level) from 01/01 till 31/12/2013. The study was approved by the Faculty Ethical Committee. Inclusion criteria were: 1) live singleton pregnancy, 2) cephalic fetal presentation, 3) lack of uterine scar, 4) monitoring in labor ward by 4 cm of cervical dilation, and 5) delivery at term. For every record, the expected time of delivery (ETD = 6 hours after 4 cm of cervical dilation) was considered “alert EDT” to which 4 hours were added to obtain the “Action EDT”. Irrespective of other fetal and maternal features contained in the traditional partogram alert and Action ETD were checked a posteriori on Debdas’s model to derive the appropriate outcome of labor. Results: The study included 357 participants, of which 219 primiparous and 138 multiparous. Vaginal delivery took place in 91% of cases. Full cervical dilation was achieved after 8 - 9 hours (9.5 ± 1.8 hours for primiparous and 8.4 ± 1.7 hours for multiparous women), namely 2 - 3 hours following alert ETD). This duration is close to the Action ETD. For 32 cesarean sections (9%) final decision took place within the alert ETD. Conclusion: Using only alert and Action ETD was found convenient to derive appropriate measures for the outcome of labor. So, the paperless partogram is a simplified method to manage the active stage of labor that could prevent prolongation of labor in our setting.
