  1. Time series neural network model for hydrologic forecasting

    水文預報的時間序列神經網路模型
  2. In fact, hydrology system is dominated by the objective factors, such as weather, geography and human activities, with combination of determinacy and randomness. the chaotic analysis method combines determinacy and randomness, which seems more adaptive to describe hydrologic time series than conventional hydrologic methods, and becomes more and more attractive recently

    本文打破以往傳統分析中單一的確定性分析或隨機性分析,在水文日流量時間序列中,引入將兩者統一起來的混沌性,系統地研究了水文流量的混沌非線性時間序列法。
  3. In this paper, a series of surveys on road condition, pavement - performance and destroy reason are analyzed, soil property, hydrologic regime are combined, modulus of resilience are confirmed on heavy compaction test, foundation classification in area of qinhuangdao is divided into 3 grades and highway is divided into 3 districts according to the principle that different soil grades produce the same effect on thickness of base course or bottom course, classification of traffic is divided into 4 grades after observation materials of traffic volumes are collected extensively, traffic characters and parameters are analyzed

    本課題在對現有路面結構狀況和使用狀況進行調查,並對路面使用性能和破壞原因進行分析的基礎上,結合秦皇島地區的土質、水文條件,確定重型擊實標準條件下土基回彈模量值,依據不同等級土基對路面基層或底基層的厚度產生大致相同效應的原則,將秦皇島地區地基強度等級劃分為三級並將本地區公路分成三個區。在廣泛收集交通量及組成的觀測資料,了解交通特性,進行交通參數分析后將交通量等級劃分為四級。
  4. In this paper, the chaotic nonlinear time series method was applied to improve hydrologic inflow data analysis. firstly, chaotic characteristics, i. e., fractal dimension and maximal lyapuonv exponent, and state space parameters, including time delay, reconstruct dimension and neighborhood radius, were calculated respectively. fractal dimension was estimated by g - p saturation correlation dimension method, and maximal lyapuonv exponent was calculated by two methods, namely, rosenstein method and kantz method

    文中利用沙溪口的日流量時間序列,研究了水文混沌非線性時間序列的特徵量,即分維數和最大lyapunov指數的計算,以及相空間重構參數,即時間延遲、嵌入維數和領域搜索半徑的選取。
  5. In this paper, a set of medium - and - long - range hydrologic forecast models were established for predicting water regime in shanghai, including three hydrological series, annual rainfall and rainfall during flood season for one representative station and annual maximum water tide level at huang - pu park. the prediction models includes two parts. one is quantitative ones which are mainly studied in the paper, including ar ( p ), gm ( l, l ), modified gm ( 1, 1 ) and threshold ar modeling ; the other is markov chain qualitative modeling

    研究分兩個方面,一是定量預測,是本論文的主要研究內容,共建立了四個預測模型,分別是ar ( p )模型、 gm ( 1 , 1 )模型、改進gm ( 1 , 1 )模型及tar模型;其二是建立了馬爾柯夫定性預測模型,給出分級預測結果。
