The formation process of flood hydrograph in a river basin can be expressed by the combination of the conversion process from rainfall to runoff in divided sub-basins and the concentration process of the runoffs in a stream net. The objective of this

When a river dike breaks down, the flowing water of higher level in a stream channel runs outabruptly from the part of breaking. The motion of water which runs out in an inland area hasbeen studied by hydraulic experiments or by numerical calculation

The runoff phenomenon of a heavy rainfall in a river basin is divided briefly into thetransformation process from rainfall to outflow on mountain slope and the propagationprocess of water resulting from the above outflow in river channel. As the part

In the previous paper, we concluded that flood hydrographa from the whole river basin(4. 4 k㎡) can be calculated directly using hydrographs from the smaller sub-basin (0. 18k㎡) included in it, under the following assumptions1) The flood hydrograp

Estimation of evapotranspiration (ET) rate is an important part in the longterm runoff calculation. If there is no data that can be used to calculate the ETrate of that basin, some approximation must be used as the first step. Thornthwaiteor Hamon eq

We have been studying the formation process of a hydrograph of storm runoff, using a set ofunit basins and the stream net which connects these unit basins. In the first part of this paper, we describe the roles of the unit basins and the stream net i

Although many observational researches on the experimental basin have been carried out inthe world, including our research, it is not confirmed whether the research results in the basin canbe extrapolated to estimate the runoff hydrograph from a larg

This paper describes the relation between soil moisture profile and groundwater runoff in Araexperimental basin, and the quantity of interception and evapotranspiration obtained by waterbalance equation. These results are as follows:1) Observed groun
