ABSTRACT : The objectives of this research are to integrate hydraulic model and Geographic Information System (GIS) for study of Mae Klong River runoff and to create flood risk map based on hydrology and hydraulic approach. The process involved runoff frequency analysis for designing runoff frequency, and developing GIS data for generating Digital Terrain Modeling (DTM) and integration of Hydrologic Engineering Centers River Analysis System (HEC-RAS) with the DTM to develop regional model for flood plain determination, and design flood return periods to a model for simulation of the prevention, warning and forecasting.
The result from the simulation model of flood in 1996 was properly presented in GIS and DTM. The DTM was derived using contour lines, river spot height and riverside spot height data. Accuracy of the model was 60 % based upon the comparison of the flooding area in 1996, interpreted by Royal Irrigation Department, and flood simulated by the model.

摘要：本研究的目的是整合的夜功河径流研究水力模型和地理信息系统（GIS），并建立洪水风险图的水文和液压的方法。该过程涉及径流频率设计径流频率分析，并发展与DTM的生成数字地形模型（DTM）与工程中心的长江水文分析系统集成（港灯- RAS）的制定平原洪水的区域模式的决心，和地理信息系统设计洪水重现期为一个模拟的预防，预警和预测模型。
从1996年的洪水仿真模型的结果是正确地介绍地理信息系统和数字地面模型。推导出的DTM使用等高线，河流点的高度，沿江现场高度数据。模型的准确度为60％后，1996年洪水比较面积皇家灌溉部解释，为基础，洪水模拟的模型。应当进一步研究做了较大的盆地，如夜功盆地为分deviding流域。该网络连接的方法结合起来subbasins应采用有一个盆地概述。在冲积平原，河道，人为的结构和地理信息系统数据库，径流量是重要的因素的研究径流量的行为和预测洪水区。进一步研究，建议将包括粗糙度值，微妙的地理信息系统数据，遥感数据和数据库管理。
问题补充：引言洪水是一种自然现象，到处发生
