Unsteady State Condition Drainage of Sloping Land Theoretical and Experimental Results Concerning tubbasin (Cojocaru,I.1985) has indicated that drainage, due to climatic and hydrogeological characteristics, functions in that zone under unsteady state condition. The dimensioning of drainage for this operational regime consists of finding out those technical characteristics for which the dynamic ev

The Controller of Pumping Aggregates in Draining Pumping Stations in Poland,istula river delta cover the area of about 170 000 ha and there are 115 pumping stations. The tidal flats are about 8 m over sea level to about 2 m below sea level. The pumping stations have there very important functions as the elements of the water-economic system. The efficient and reliable contr

A Method of Flood Routing in Ungauged Catchments with Particular Reference to Proposed Changes. A Clternative methods for river flood routing, whilst offering significant advantages in speed of computation and simplicity. A method to predict variable coefficients from steady-flow backwater curve analysis has been developed which, when used in a Muskingum flood-routing routine, compares favourably

New Drainage Formulas Considering Delayed Gravity Response and Evaporation from Shallow Water Tableor a certain soil is a function of rate of drawdown and initial depth to ground water table, as well as intensity of evaporation. The formulas for water table draw-down with delayed gravity response have been developed by Neuman (1982) on the basis of 2-D flow equations.

Unsteady State Condition Drainage of Sloping Land Theoretical and Experimental Results Concerning tolution of the depletion curve, under the influence of water intake and outflow, satisfied the drainage duty permanently. The evolution of the depletion curve may display 3 situations:.In the paper herein it is analysed the raising stage of the depletion curve in the conditions of a systematic drainage located on an impervious layer.
