| Since the construction and use of San Men Gorge reservoir, the conditions of water and sediment and evolvement laws of riverbed of lower reaches of Wei He River had taken place greatly. The lower reaches had changed from the river of the balance of scour and sediment to that filled up strongly, from that not fortified to fortified, from save and affluence to calamities frequently, and became the typical example of the lower reaches of the Yellow River. The mission of flood control is very huge. Since Wei He River locates at the accordant junction area of the Yellow River, Luo He River, Jin He River, Wei He River and other tributaries in South Mountains, the problems of water and sediment are very complex, and so the flood control and treatment of the river are rather complicated, formidable and perennial and integrative treatments have to be taken for the whole drainage area.The no engineering measure occupies the very important position in Shan xi province San Men Xia reservoir area districts defend anti work, but the water rain feeling measures one of the key measure of the report forecast right and wrong engineering measure. For the sake of tradition that changes area water lover's work falls behind to measure the report method, setting up one after another in 1999 the area water level measures the report system automatically, two automatic telemeter in volume of rain in subsidiary current in mountain in south in Tow Hua (Hua County, Hua Yin) system, face the Lin Tong, Nan Rong Hua automation way measure to flow the system.3 systems sets up the devotion makes use of feeling the advanced telemeter, correspond by letter, the high and new technique in etc. in calculator used for area water rain feeling measures the report, increasing consumedly water rain feeling measure the report level, defending the conductor for the area all levels the section provided quick, on time, accurate and dependable one hand water rain feeling data, defend the anti- for the reservoir area of the decision puts into practice the work won very precious time, the flood control in the reservoir area of reduced to develop the enormous function in the disaster. But, because of suffering to invest budget and local water rain feelings to measure the restrict of the soft hardware in report technique development automatically, especially the reservoir area of many sediment headstreams complexity affects, making the area of set up usage of 3 measure automatically the different degree in system in report exists some blemish. And, the reservoir area of measures the water feeling data of the report did not further handles automatically, having no 1 software for keeping view, development, image keeping watch on, automatically playing showing, forecast terrace.This research the design aims at above existent of some problem, combination oneself the work is actual, making use of to have can see the design tool that turn and have to face to the object drives with affairs the function and have the dynamic data exchange( DDE) the function and have the dynamic chain connects the ( DLL) function with the Visual Basic that have the open type the database conjunction the function( ODBC) language conduct and actions design tool, development design Shan Xi province San Men Xia reservoir Districts water feeling information multi-media surveillance forecast system software, realize Wei river downstream 4 kinds of typical models flood at course of river is with the number that District evolve imitate the true multi-media development plays to show, to reservoir area water rain the feeling measure to number off automatically according to the proceeding further handles, realize reservoir area water, rain the feeling measures to number off automatically according to dynamic image in multi-media solid hour surveillance forecast. From but adjust for the flood control the degree provide the clear and available water rain feeling with decision surveillance forecast work terrace.
