HIDROGRAF SATUAN SINTETIK SEMBILAN SUNGAI DI JAWA TIMUR

THE SYNTHETIC UNIT HYDROGRAPH FOR NINE RIVERS IN EAST JAVA

Author :
SUWIGNYO 




ABSTRAK

Unit Hydrograph UH is used as one of methods to calculate design flood. UH is derivate from discharge and precipitation on watershed. The limitation of the data and places for UH brings about ideas to develop The Synthetic Unit Hydrograph SUH. The Research and modeling of SUH to improve parameters of SUH QP TP and TB with the simple watershed physic characteristic the watershed area A length of main stream L slope of mean stream S and factor of watershed type FD. Modeling the SUH parameters uses Regression Statistical Method with four variables of watershed in individual and combination of it. From the Research of four watershed variables the variables A L and FD have strong linear influence sensitive to parameter of peak discharge and the variables FD A and S sensitive to the parameter of peak time of SUH. The modeling result parameter of peak discharge QP 020 . A073 with adjusted determination coefficient very high R2 0871 and the parameter of peak time TP 117 . S006 FD-092 with R2 0922. This research must develop with more data to rises the stability of model coefficient and definite the best model can be based on R2 and Sum Square of Error SSE. The Research factor of watershed type FD has not discussed the influence of watershed geometric position to parameter of peak time yet.
